Non Technical Summary
The honey bee, a pillar of the economy for providing pollination services and producing honey, is battling unprecedented population decline. Research efforts to identify the culprit behind this phenomenon have culminated in a multifactorial etiology, including stressors such as pathogens, chemical toxicity, and poor colony management. The intricacy of the problem entails a mitigation approach that adopts an integrated analysis and scrutiny at local levels. In the research part of this proposal, we suggest conducting a holistic survey of pathogen incidence, pesticide residues, and colony losses occurring in apiaries throughout Kentucky. The disease diagnosis of sampled hives will be achieved through molecular and metagenomics methods and linked to potential pesticide exposure uncovered by chemical analysis of hive matrices. The colony loss rate in relation to risk factors such as poor management will be determined by an epidemiological survey using a questionnaire. In the teaching part of this proposal we suggest curriculum improvement by enhancing existing courses with practica and new teaching tools as well as developing a new Genomics course. This integrated project also proposes improving our extension services through the development of custom-based solutions, determined by field data, that will take into account beekeepers' tangible needs.If funded, this project will strengthen the capacity of the longstanding Apiculture and Pollinators Health Program at KSU, which delivers translational research, education, and outreach to stakeholders. The program serves the Institution's goal to close the achievement gap of under-represented minority and low-income students in STEM fields.

Goals / Objectives
a. Objective 1: Map honey bee disease prevalence in Kentucky apiariesRationale: The epidemiological analysis of colony losses is confounded by a relative dearth of bee pathogen field studies, and Kentucky is no exception. Monitoring disease agents can help control their spread and solve problems that compromise colony strength. Hence, we propose to map the spectrum and abundance of infectious agents in Kentucky apiaries. To achieve this goal, honey bee samples will be collected from apiaries across the state. To capture seasonal variations in incidence and abundance of pathogens, the sample collection will be performed strategically throughout the year. In order to connect type of pathogens to overall colony health, the samples will be categorized in three classes according to the strength of their original colony: weak, moderated, and strong. To identify pathogens and prevalence of pathogens in the collected samples, a metagenomics strategy will be adopted. We suggest using RNA-seq technology to survey a wide range of pathogens and to detect unexpected or rare taxa by mapping reads against inclusive sequence databases. Confirmation of select viruses and pathogen loads will be done via quantitative RT-PCR.b. Objective 2: Identify and quantify pesticides contaminants in Kentucky apiariesRationale: Under field conditions, honeybee colonies can be exposed to bio-aggressors concomitantly with pesticides, making co-exposure to pesticide/bio-aggressors a primary concern for honey bee health. Because synergy between environmental stressors influences colony strength and survival, we suggest a more holistic approach to surveying honey bee health in Kentucky apiaries. This approach is suitable to detangle the complex multifactorial problem compromising hive strength. We suggest performing a residue analysis of pesticides that are commonly used in Kentucky and that are potentially toxic to honey bees. When collecting bees for disease incidence analysis, we will concomitantly collect two hive matrices, pollen (capped pollen or beebread) and beeswax, which will be tested for pesticide residues. A comprehensive pesticide residues study of hive samples from across the U.S. showed that the type and amounts of pesticides contaminants are well represented in the stored pollen and wax (a slightly larger number of pesticides were found by in samples of other matrices). The same study found that bees contained the fewest residues, and these were at lower levels, possibly due to biotransformations and rapid excretion. Beeswax and capped pollen (as opposed to trapped pollen) are more conveniently sampled from hives and do not put any burden on beekeepers. Hence, we reasoned that capped pollen and beeswax are suitable hive matrices for our purpose.c. Objective 3: Epidemiological survey of honey bee colony losses in KentuckyRationale: A pan-European survey study probing 5,798 apiaries to identify risk factors associated with colony lossfound that the highest and lowest mortality were correlated to occurrence of diseases and beekeeper background. Beekeepers with better knowledge on disease detection and management, applying earlier prophylactic measures and good beekeeping practices, such as preparation of colonies for winter, had lower mortality rates than others. Based on the study, the authors concluded that the main factor protecting honey bee colonies are beekeepers' managing skills, and recommended promotion of regional scale studies of local practices.In the U.S., a national survey study questioning 6,482 beekeepers to document overwintering mortality rates during the 2012-2013 season revealed that colony losses were attributed to different reasons depending on the beekeeper operation type: backyard beekeepers identified "manageable" factors as the causes of their loss (e.g. starvation and weak colony in the fall) while commercial beekeepers suggested "non-manageable" factors (e.g. queen failure and pesticides).In light of the above findings, we propose to survey winter colony mortality, which is a standardized parameter to quantify apiculture and directly linked to colony management. With this survey we aim to identify the magnitude and spatial distribution of honey bee colony losses in Kentucky and collect information to correlate the losses to possible determinants, including Varroa control, poor winter preparation, and poor nutrition. This will enable the provision of recommendations regarding control of colony stressors to prevent or diminish losses.d. Objective 4: Improvement of curricula and development of new course materialsRationale: Courses such as ENV 545 (Molecular Methods) and Bio 307-01 (Genetics) are based on both, lectures and laboratory sessions, and both include genomics topics but no practicum to demonstrate the workflows related to these topics. To remedy this shortcoming, we will develop new instructional materials as well as incorporate laboratory sessions related to genomics and metagenomics into both courses. Since ENV 545 is an elective that is offered every other year, we will develop a new course ENV 585 Special Topic/Genomics that can be offered during the years ENV 545 is not offered. ENV 585 Special Topic/Genomics will be exclusively focused on genomics with more in-depth outlook on pathogen surveillance. Other existing courses will also benefit by incorporating some or all instructional materials developed under objective 4 (see course list in table 1).e. Objective 5: Improving extension services to Kentucky beekeepersRationale: KSU is the only Land Grant university offering extension services in apiculture in the state of Kentucky. Assuming this role necessitates gathering data to infer the overall health of beehives in Kentucky as well as having an appreciation of the prevalent beekeeping practices in the different regions of the state. Yet to this date, there was no global effort to collect samples from beekeepers due to lack of resources. Our Extension services will grandly improve with a better understanding of pesticide use and type of prevalent diseases per region as well as possible shortcomings in management practices, especially from new beekeepers. This is why, through this project, we will gather data that will be used to devise better solutions/advice to local beekeepers.
Project Methods
a. Under Objective 1: Map honey bee disease prevalence in Kentucky apiariesi.) Sample collection: Colonies from apiaries located in the different physiographic regions of Kentucky will be sampled during winter, spring, summer, and fall. The large-scale sample collection will include roughly 30 colonies/season/region for a total of 480 samples.ii.) Metagenomics approach for pathogen diagnosis and prevalenceRNA extraction: For each sampled colony, 50 bees will be pooled to extract RNA. The obtained RNA extracts will be pooled according to their respective region, season, and colony strength, leading to a maximum number of 48 treatments (region/season/colony-strength). Each RNA pool will be converted into a cDNA library in triplicate for deep sequencing. This design will lead to about 144 cDNA libraries, with a total of 24,000 analyzed bees (480 colonies x 50 bees).Deep sequencing and statistical analysis: We will adopt the strategy used by Tozkar [54] since it was based on the CLC Bio platform and was successfully used to identify and quantify honey bee pathogens.b. Under Objective 2: Identify and quantify key pesticide residues in Kentucky apiariesBeeswax and stored pollen will be collected when bee hives are sampled (Objective 1); we will randomly select a subset of the weak, moderate, and strong hives to remove about 15 g of stored pollen and 15 g of burr comb, which will be placed on ice and subsequently frozen until analysis.Beeswax and pollen samples will be analyzed for a number of pesticides selected based on their possible toxicity to honey bees, their detected presence in hives, and wide use in Kentucky. Samples will be shipped, on ice, overnight to USDA-NSL in Gastonia, North Carolina, for processing. Conventional gas chromatography-mass spectrometry (GC-MS) or the more sensitive liquid chromatography-tandem mass spectrometry (LC/MS-MS) will be used appropriately to the type of pesticides.c. Under Objective 3: Epidemiological survey of honey bee colony losses in KentuckyWinter colony loss can predict seasonal losses and is commonly used as an indicator of the overall losses; hence the survey will focus on winter mortality. The epidemiology study will be designed to estimate overwinter colony loss rates, identify areas with a higher or lower risk of honey bee mortality, and gather information on possible determinants. Data collection will be facilitated by means of a standardized, self-administrated questionnaire, available online.i.) Sample size: To ensure a large sample size of respondents answering the questionnaire, different platforms, especially beekeeper associations, will be used to reach participants. The Kentucky State Beekeepers Association, which has about 2,500 members, has agreed to offer the survey to its members (communication of the President, Chris Renfrow). The Kentuckyana Beekeepers Association, which has more than 100 members, also agreed to offer the survey. Other venues, such as different county meetings, will also be contacted to offer the questionnaire to their beekeeping audiences.ii.) Questionnaire and pilot survey: A standardized, self-administrated questionnaire will be developed to obtain epidemiological data on apiaries in Kentucky. KSU expert apiculturists Dr. Webster and Joseph Palmer will participate in the survey content and planning.iii.) Data analysis: Anticipating that the survey population of beekeepers in Kentucky will be mainly small and intermediate operations, we will consider six classes: small hobbyist (1<5 colonies), medium hobbyist (5-15 colonies), large hobbyist (16-50 colonies), small commercial operations (51-150 colonies), medium commercial operations (150-500 colonies), and large-scale operations (>500 colonies).d. Under Objective 4: Improvement of curricula and development of new course materialsThe improvement of course curricula will be approached in two ways: incorporation of live laboratory sessions and creation of virtual labs. The courses in which the new laboratory live sessions will be incorporated are ENV 545 Molecular Methods, Bio 307-01 Genetics and ENV 585 Special Topics. The course ENV 585 is an umbrella graduate course under which different topics are taught depending on the instructor. PD Dr. Olden has developed and taught ENV 585 Special Topic/qPCR, which is a lecture/laboratory hybrid course. With the current proposal, we will develop ENV 585 Special Topic/Genomics. Other courses that can benefit of all or part of the developed materials from this proposal areAFE 443 Apiculture and Pollination Biology (Undergraduate) andAFE 307 Animal Nutrition Undergraduate.i.) Live laboratory sessions: The metagenomics data collected through this project will be used for laboratory exercises to reinforce the theoretical part of the course with hands-on experience. The lab exercises will consist of the re-creation of the workflow used to analyze the sequences of the project.ii.) Virtual laboratory sessions: To accommodate the growing need for course materials that are asynchronously accessible via the internet, we will develop course modules that are video recorded and made available to students. This crucial need has been a limiting factor of the online transfer of the courses during this COVID-19 pandemic. We will thus video record RNA-seq analysis steps by reanalyzing data of previous projects as well as video record metagenomics analysis of the present proposal while analyzing the data.e. Under objective 5: Improving extension services to Kentucky beekeepersi.) Workshops and Third Thursday presentations: If this proposal is funded, the additional manpower (hired technical/extension assistant) and resources that will be available will be used to develop workshops, extension fact sheets, publications as well as Third Thursday presentations for local beekeepers. Our efforts will focus on the problem areas identified from the information gathered during the project. For example, if the genomics data show a prevalence of a particular disease such as varroa, then varroa prevention and management presentations will be developed. The management practices survey will also be valuable to determine the type of workshops to offer. For example, we predict that beekeepers might have difficulties when supplementing their colonies with food. Indeed, there are multiple types of bee food that are commonly used to supplement the natural food stores of the colonies. The most common are pollen patties, sugar syrup, and sugar candy. All of these food types have different uses and applications depending on colony size, time of year, and amount of food stores in the colony. Also, there are different ways to administer each type of feed and using the wrong feed type or application method can be detrimental to the colony. For example, using an entrance feeder to feed sugar syrup during a nectar dearth will trigger "robbing" from other nearby colonies. This "robbing" can lead to colonies being depleted of all food stores, resulting in starvation and death of the colony despite supplemental feeding. Another example of food supplement misuse is the implementation of high moisture feed during winter, since it increases the humidity inside the hive, which makes it difficult for the bees to stay dry and warm. Additionally, mixing these feeds can be intimidating to beekeepers, causing many to purchase premade food supplements, although some are not as beneficial to bee health or as affordable as homemade options.

Palmer J, Holbrook K, Olden F. 3/09/2024 Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?During this period, I had the opportunity to learn how to effectively use the survey platform Qualtrics for conducting surveys. This allowed me to produce data that was statistically analyzed, yielding results that are instrumental in improving beekeeping practices in Kentucky. Additionally, conducting pesticide residue analysis provided me with the chance to expand my knowledge of chemical concepts and enhance my skills in statistics through the processing of raw data using software such as Prism. This project also facilitated several partnerships, including collaborations with the Bioinformatics Core and the Metagenomics Core at the University of Delaware, as well as the Biotechnology program at BCTC. These partnerships not only advanced the project goals but also provided valuable opportunities to examine in depth various approaches for handling large sequencing data to obtain the most accurate results.

Bluegrass Bee school, Frankfort KY 3/09/24 What do you plan to do during the next reporting period to accomplish the goals?During the upcoming reporting period, our aim is to achieve the disease mapping objective by completing all RNA extractions, library sequencing, and bioinformatic analysis of fall, spring, and summer bee samples. Regarding Objective 2, we plan to finalize the pesticide analysis of spring and summer samples. For Objective 3, we intend to complete the distribution of the large survey and analyze the collected data. Additionally, we will continue developing educational materials to support Objective 4. Utilizing the outcomes of all these objectives, we will sustain our extension efforts across Kentucky to fulfill Objective 5.

What was accomplished under these goals? Objective 1: Map honey bee disease prevalence in Kentucky apiaries Sample collection for the Spring and Summer seasons was conducted between April and September 2023. The six physiographic regions--Bluegrass, Knobs, Eastern Coal Field Region, Mississippi Plateau, Western Coal Fields, and Jackson Purchase--were visited, and samples of wax, bees, pollen, and honey were collected from about 10 apiaries per region. The collected bees are intended to fulfill the disease prevalence objective. Also, during this reporting period, RNA extraction from 277 samples of the fall season and the subsequent sequencing of 57 libraries were completed. The metagenomic analysis of these libraries has been completed, and the bioinformatic analysis of the generated sequencing data is in its final stageto identify and quantify the pathogens present in the fall samples.For the spring samples, the RNA extraction of 125 bee samples and the sequencing of the generated 18 libraries, are in progress. Finally, the processing of the Summer samples is scheduled to be completed in March 2024 for RNA extraction and library sequencing during summer 2024. b. Objective 2: Identify and quantify pesticides contaminants in Kentucky apiaries Sample collection for the Spring and Summer seasons took place from April to September 2023. Visiting the six physiographic regions--Bluegrass, Knobs, Eastern Coal Field Region, Mississippi Plateau, Western Coal Fields, and Jackson Purchase--we gathered samples of wax, bees, pollen, and honey from approximately 10 apiaries per region. The collected pollen was gathered specifically to address the objective of assessing pesticide contamination prevalence. As of March 2024, hundred-thirty-one hives of the fall pollen samples have been processed. The pesticide residue analysis was performed using GC and LC-MS/MS multi-residue screen that includes 468 analytes. The analysis generated results that are available for Kentucky beekeepers and for further downstream analysis. c. Objective 3: Epidemiological survey of honey bee colony losses in Kentucky During this period, we report that a final number of 57 beekeepers participated in the pilot survey, all of whom were involved in the hive matrices collection and citizen science aspect of this project. The survey responses, whether in hard copy or emailed attachments, were processed and entered into the Qualtrics survey platform. The survey results were then analyzed using the Qualtrics data analysis tool. The final results of the pilot survey proved instrumental in refining the final large survey questionnaire that is intended for a wider participation of beekeepers across Kentucky. As of March 2024, the large survey has been distributed via links or QR codes at conferences and bee schools, resulting in 190 beekeepers completing the survey thus far. d. Objective 4: Improvement of curricula and development of new course materials During this period, our focus was on developing teaching materials, particularly by exploring videography techniques. We acquired materials to enable research associates and graduate students to record videos while conducting fieldwork, allowing us to capture the techniques and protocols used in field trials and beekeeping at our apiary. Additionally, we established a partnership with Bluegrass Community & Technical College (BCTC), providing them with fall pollen samples and reagents in exchange for conducting sequencing to identify the pollen species in these samples. This collaboration involves both BCTC students and our graduate students, allowing them to learn new molecular biology research protocols. e. Objective 5: Improving extension services to Kentucky beekeepers ? During this reporting period, we maintained our efforts to connect with beekeepers across Kentucky, aiming to raise awareness about the KYSU pollinator research and extension program, and to address beekeeping questions through Q&A sessions following our presentations. We continued to organize oral presentations during monthly meetings held in various locations throughout Kentucky, including Russell County, Clark's River, Little Sandy, Spencer County, and Northeast Kentucky. Additionally, we participated in events such as the Kentucky State Fair, Cynthiana Honey Festival, and the ApisRescue conference, among others. We also renewed our presence at the Bluegrass Bee School and conducted a workshop focusing on testing and treating for varroa mites. Furthermore, we delivered talks highlighting the results of this project and their significance for Kentucky beekeeping at the Bluegrass Beekeeping School and the ApisRescue conference. Continuing our commitment to raise awareness about the importance of bees and research-driven beekeeping, particularly among young Kentuckians, we participated in the Berea College Beekeeping and Bee Biology Class during their Field Work Day.

    Target Audience:Kentucky beekeepers, local associations of beekeepers (such as Kentuckyana Beekeepers Association and Kentucky State Beekeepers Association), Kentucky small farmers, Kentucky scientific and academic entities (such as Blue Grass Community and Technical College) national associations and societies (such as Entomological Society of America and American Association of Professional Apiculturists), Kentucky general public, general public and scientific community at large. Changes/Problems:This project faced a substantial two-year delay due to various challenges, including the impacts of the COVID-19 pandemic, the struggle to fill the field assistant position, and a change in direction that was suggested by the former president of the Kentucky State Beekeeper Association but turned out to be incorrect. Despite these hurdles, we have made significant progress during this reporting period. However, it is important to acknowledge that the project's scope is extensive, involving a large number of samples that require processing and complex analysis of big data, including a metagenomics analysis. The sheer volume and intricacy of these tasks mean that the project will require an extension to ensure it is completed thoroughly and accurately. We remain committed to the project's success and will continue to work diligently to achieve our objectives, ultimately delivering comprehensive and valuable results. What opportunities for training and professional development has the project provided?Through this project, I had the opportunity to delve into a novel research method involving the use of surveys for data collection. The process of developing the survey instrument proved to be an invaluable learning experience, and the final product has not only proven to be beneficial for this specific project but also holds potential value for other research endeavors at Kentucky State University and beyond. How have the results been disseminated to communities of interest?The project's objectives and sampling activities were effectively communicated through various channels, including bee schools, county monthly meetings, and online platforms like the KSU bee program's Facebook page as well as facebook pages of different regional honey bee associations. While we have actively shared information about the project, it is important to note that at this stage, we do not have any results that ready for dissemination. As the research progresses and data analysis is completed, we look forward to sharing our findings with the community and interested stakeholders. What do you plan to do during the next reporting period to accomplish the goals?This project encountered a significant two-year delay due to several challenges, including limitations imposed by the COVID-19 pandemic, difficulties in filling the field assistant position, and a new direction suggested by the former president of the Kentucky State Beekeeper Association that proved to be unsuitable. Despite these obstacles, substantial progress has been made during the year 22/23, addressing all five project objectives. However, there is still a considerable amount of work to be completed to finalize the project. In the upcoming reporting period, our focus will continue to be on extension efforts and enhancing curricula. We aim to complete sample collection ofsummer seasonand conduct data analysis for a portion of the collected samples, as well as finalize the survey. Due to the delays encountered at the project's inception and the extensive volume of samples that need to be processed, along with the complexity of sequencing and data analysis, we anticipate that the project will require an extension of at least one year. This extension will allow us to ensure thorough and accurate analysis, leading to comprehensive and meaningful results.

    Impacts
    What was accomplished under these goals? a. Objective 1: Map honey bee disease prevalence in Kentucky apiaries Sampling collection for the Fall season was conducted between September and November 2022. All six geographical regions of Kentucky, namely Bluegrass, Knobs, Eastern Coal Field Region, Mississippi Plateau, Western Coal Fields, and Jackson Purchase, were visited. In each region, ten apiaries were included for sample collection, totaling 60 apiaries overall. During these visits, a total of 285 hives were randomly selected, to collect pollen, bees, honey, and wax. As a result, four collections of beehive matrices were created, each comprising approximately 280 samples. To ensure proper sample preservation, the collections were carefully transported using dry ice and subsequently stored in -80 freezers. Moving forward, a metagenomics strategy will be employed to process the bee samples and detect potential diseases. b. Objective 2: Identify and quantify pesticides contaminants in Kentucky apiaries Sampling collection for the Fall season was conducted between September and November 2022. All six geographical regions of Kentucky, namely Bluegrass, Knobs, Eastern Coal Field Region, Mississippi Plateau, Western Coal Fields, and Jackson Purchase, were visited. In each region, ten apiaries were included for sample collection, totaling 60 apiaries overall. During these visits, a total of 285 hives were randomly selected, to collect pollen, bees, honey, and wax. As a result, four collections of beehive matrices were created, each comprising approximately 280 samples. To ensure proper sample preservation, the collections were carefully transported using dry ice and subsequently stored in -80 freezers.The pollen samples were sorted, and a subset were pooled according to the region and colony strength. Each sample that was selected for further analysis was divided in two parts which created two identical batches, one is being analyzed at Guelph University to detect the presence of pesticide residues, while the other batch was submitted to Blue Grass Technical College (BCTC) to carry out species identification via DNA sequencing. This comprehensive analysis will provide valuable insights into the health and characteristics of the bee populations in the various regions of Kentucky. c. Objective 3: Epidemiological survey of honey bee colony losses in Kentucky A comprehensive survey instrument was created, comprising a questionnaire with 37 short and direct questions. The questions were designed to elicit yes or no answers or gather simple information, such as the number of treatments administered per year. The pilot survey was executed by distributing the questionnaire via email or in person to the beekeepers. All beekeepers whose apiaries were included in the sample collection were invited to take part in the survey. This effort resulted in the collection of over 50 survey responses from the beekeepers. Additionally, the survey elicited valuable feedback, enabling further refinement and improvement of the final survey instrument. d. Objective 4: Improvement of curricula and development of new course materials In the Fall 22/23 semester, the KSU Genetics course (BIO 307) incorporated high-tech wet lab sessions to instruct students in the fundamentals of molecular genetics research. These labs were designed to be hands-on and included the utilization of bee tissue from the collected samples. During the lab sessions, students applied various techniques, such as protein quantification, DNA extraction, DNA quantification, and electrophoresis. These labs enabled students to practice current technologies but also gain insight into what research projects entail. e. Objective 5: Improving extension services to Kentucky beekeepers During this reporting period, our primary focus was on connecting with beekeepers across Kentucky to raise awareness about the KYSU pollinator research and extension program. We aimed to inform them about the program's capacity to provide support and assistance to beekeepers in their endeavors. To achieve this, we organized three engaging dialogues during monthly meetings held in different counties, including Garrard, Cynthia, and Jessamine. These dialogues allowed beekeepers to learn about our program and also provided them with a platform to ask questions related to apiculture. In addition, we conducted a specialized workshop at the Blue Grass Bee School, focusing on testing and treating for varroa mites, a common pest affecting honey bee colonies. This workshop aimed to equip beekeepers with valuable knowledge and practical skills to manage this issue effectively. Furthermore, we delivered a presentation titled "Sampling Method to Assess Colony Health in Kentucky." This presentation emphasized the importance of monitoring colony health and provided information about our ongoing project. During the presentation, we also encouraged beekeepers to participate in a forthcoming colony loss and management survey. Recognizing the significance of raising awareness about honey bees among the general public, we directed outreach efforts beyond beekeepers. One such effort involved presenting to the Berea College Beekeeping and Bee Biology Class during their Field Work Day, where we shared insights into the vital role of honey bees and their importance for the environment and agriculture. Through these various activities, we strived to foster a collaborative and informed beekeeping community while highlighting the crucial role of honey bees in our ecosystem and the importance of their conservation and protection.

      Target Audience:As part of the initiation of the reserach part of this project. We held several meetings with the board president of the Kentucky State beekeeper association (KSBA), Tom Ballinger. We held discussions of the best way to proceed with the sampling part of the project, as beekeepers might prefer that we sample our own hives. Changes/Problems:It seems like we will have to change the part about sampling the beekeepers' hives and instead purchase or lease 200 hives and place them in different apiaries. We are still exploring all avenues at the moment and will have a definite plan in few days. If such change happens there will be no issue, we have sufficiant funds to transfer to be able to adapt to this change. What opportunities for training and professional development has the project provided? Nothing Reported How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?For the next reporting period, we plan to have collected and processed the samples of at least 2 seasons (summer and fall). Winter collection will depend on whether the hives are purchased for the project or belong to the apiarists. From some discussions we had with the KSBA board president, it is very likely that many beekeepers will be reluctant to open their hives during winter.

      Impacts
      What was accomplished under these goals? a. Objective 1: Map honey bee disease prevalence in Kentucky apiaries The bee health laboratory has been set upto store and process the samples. The lab has now the capacity to receive and analyzea large number of samples. RNA extraction and quantification as well as for qPCR analyzis are now doablein the lab due to the purchase ofequipment including Applied Biosystems QuantStudio3 qPCR system and a BMG Labtech Omega Plate reader with absorbance, fluorescence, & luminescence. b. Objective 2: Identify and quantify pesticides contaminants in Kentucky apiaries The Bee health lab has now the capacity to receive a large number of samples due to the purchase of a freezer and a refrigirator. The sampling in itself has not yet started as we are discussing the best way to carry out this important objective without unacommodating the beekeepers. Meetings have been held with the board president of KSBA. Also we are readvertising the Apiculture Research Assistant position as a Technical assistant, since most of the experienced apiarists do not have a high education level. c. Objective 3: Epidemiological survey of honey bee colony losses in Kentucky KSBA, board president, Tom Ballinger, has confirmed that we can use the association's website to conduct the survey d. Objective 4: Improvement of curricula and development of new course materials Wet lab sessions to teach students the principal of molecular genetics research (i.e. DNA/RNA extraction and quantification, and electrophoresis) were integrated for the first timesince the start of the Genetics course. Students, for example, learned about DNA extraction and the evolution of the electrophoresis system to the high-tech simple and fast technology using Invitrogen's Power E-gel. e. Objective 5: Improving extension services to Kentucky beekeepers This objective has not yet been achieved.
