What do you plan to do during the next reporting period to accomplish the goals?Our team will continue to gather input from growersand our advisory board. This winter we have a few team members leaving through graduation and/or contracts ending, so we will be re-evaluate our alignment of team members and objectives with the remaining budget to complete the proposed research. While our main fieldwork is complete, there are some targeted field experiments planned and continued greenhouse research we expect to complete in 2024.

What was accomplished under these goals?
Objective 1. Conduct cost-benefit analyses of different honey bee stocking density and placement strategies to develop recommendations for modern blueberry systems.Data evaluating the effects of different honey bee stocking densities were collected from multiple field sites in Michigan and Florida. Preliminary analyses of data from Michigan have been completed and included in a graduate student's thesis. Remaining data analyses are underway across the whole project to synthesize how various measurements of honey bee abundance relate to pollination service in highbush blueberry.Field studies assessing the effects of honey bee hive placement on blueberry pollination and pesticide exposure are complete with data collection completed in 2021-2023 in Michigan, Oregon, and Washington. During the visits to these farms, there were opportunities to collect data for building and validating the bloom predictor in Objective 3. All results are being shared with our collaborating economist who is conducting cost-benefit analyses of various hive density and placement strategies for incorporationinto our Pollination Planner (Objective 4). Objective 2. Determine pollination requirements and pollinator attraction across new and existing cultivars. We compared the pollination requirements of 11 northern highbush blueberry cultivars by conducting hand pollination experiments. Specifically, we assessed autofertility, self-fertility, and cross pollination with varying single pollen donors and multiple pollen donors. For all pollination treatments, we assessed fruit set and berry weight. We are currently assessing seed set, sugar and acidity, and firmness in all resulting berries. Time to ripen for all berries across all pollination treatments was also calculated. Additionally, we compared variation in floral traits across 10 southern highbush and 9 northern highbush cultivars including nectar volume and nectar sugar content, flower density, and flower morphology. We additionally collected anthers from all cultivars and are in the process of assessing pollen quantity and its variation across cultivars. Our preliminary results show that cross-pollination increased fruit weight per flower significantly by 14-420% depending on the cultivar in 9 of 11 cultivars, with no significant increase in the other 2 cultivars. It also significantly decreased the time to ripen by 4-18 days in 5 cultivars, and it significantly increased the fruit firmness by 6-38% in 7 cultivars. There was also nearly no parthenocarpy for any cultivar. The total amount of nectar secreted per flower varied by 4.6-fold in southern cultivars, from 2.0 ± 0.5 in 'Farthing' to 9.3 ± 1.2 mg of sugar per flower in 'Kestrel', and by 2.1-fold in northern cultivars, from 6.2 ± 1.1 in 'Bluecrop' to 12.8 ± 1.4 mg of sugar per flower in 'Draper'. Northern cultivars secreted more nectar per flower than southern cultivars. Corolla length and aperture diameter also varied greatly among cultivars and between northern and southern cultivars. Flowers of northern cultivars were on average smaller than flowers of southern cultivars, with shorter corollas (ranging from 7.3 to 9.2 mm in northern and from 8.3 to 11.5 mm in southern cultivars) and shorter aperture diameters (from 2.3 to 3.4 mm in northern and from 3.4 to 5.2 mm in southern cultivars). Studies to compare attraction of bees to different cultivars were started in 2023, but low bee abundance, scale of the experiment, and weather conditions all contributed to low bee activity in the trial. Revised plans will be developed with our advisory board's input this winter. Objective 3. Determine how variable weather conditions affect blueberry pollination. Repeated counting of opening blueberry flowers was done on bushes of various cultivars in multiple farms and across the states within this project. This information is being used to construct degree-day based models of bloom phenology that can be integrated into local weather networks to provide updates to growers on bloom timing and when bee delivery should be planned. This can also guide changes in pest management activities once bloom ends and honey bee hives are removed from the fields. Data on bee activity and environmental conditions has been collected across two field seasons in all four states. Those data are being collated for a project-wide analysis of how environmental conditions affect bee foraging activity. The effects of extreme weather conditions have continued to be evaluated in laboratory and some field studies. Blueberry pollen was collected from various southern highbush blueberry cultivars and germination and pollen tube growth of the pollen were measured across a range of temperature conditions from 10 to 37.5 oC (50 to 99.5 oF). Results from this study show similar results to the recent Walters & Isaacs (2023) study in terms of the response to different conditions. Extreme high temperatures inhibited pollen development in a similar way to the earlier research, but we also found that on average the southern highbush cultivars were better able to develop at 10 oC compared with the northern cultivars. Overhead irrigation was tested at a research planting to determine the degree of cooling provided. intermittent irrigation during the hottest parts of the day reduced the air temperature by 5-10 oF. To determine the effect of humidity on pollen production, pollen production was compared in 'Emerald' when the conditions were 45 or 85% relative humidity. Pollen was mostly released during the first day after flower opening when the growth chamber was set at 45% RH. At 85% RH, pollen was never released, indicating that high humidity conditions are not conducive for pollen release. This may be a mechanism for flowers to hold pollen until bee activity is more likely, and a follow-up experiment indicated that flowers held at 85% RH will release pollen once the flowers return to lower humidity conditions. Objective 4. Develop predictive models of pollination, fruit set, and yield for creation of a Pollination Planner to improve pollination management decisions.A draft Pollination Planner interface was created and presented to growers and crop consultants in all participating states in a focus-group setting in order to get feedback on optimal interface design and model utility. The draft Pollination Planner included a beta-version of a bloom phenology model that incorporated data from Michigan and Washington. Additionally, the Pollination Planner had a beta-version of models that estimated the effects of changing hive density on blueberry fruit set, berry weight, yield, and profitability. Model refinement is underway and feedback as well as new data will be incorporated into the next generation model circulated for the 2024 growing cycle. ?Objective 5. Deliver information on improved blueberry pollination to the industry. Information from the project was delivered to 1,639 contacts at 15 grower talks and 6 field days in Washington, Michigan, Oregon, Florida and the Canadian province of British Columbia. We also produced a 17 min video for growers to learn to grade colony strength in blueberry fields using hive entrance counts, which has resulted in 122 views. We also produced three podcast episodes highlighting aspects of the project (listed below) resulting in 4,588 downloads. Our website continues to grow in visibility and content with materials from the project being added as they become available. The project was also covered in two trade publications and three scientific publications.

What do you plan to do during the next reporting period to accomplish the goals?Second-year data from Florida will be collected for the hive density experiment and associated cost/benefit analysis will be completed. We also plan to estimate the income effects using data from a yield model developed in Objective 4. We plan to repeat Obj. 1a across ~8 farms in Florida. We will also collect data relevant for Obj.3 including weather and bee foraging rates on these same farms, and potentially bloom phenology and weather for degree-day models. We will conduct pollination experiments on northern highbush cultivars for Obj. 2 and additionally conduct an experiment for Obj. 2 designed to assess the relative attractiveness of different blueberry cultivars and the floral traits that determine attraction. Pesticide exposure data collection will also be finalized, and all project data will continue to be analyzed based on advisory board feedback and prepared for publications and dissemination to industry stakeholders. Additionally, data will be shared with the Objective 4 team for the Pollination Planner. For Objective 5, we will publish the survey results as extension bulletin, and conduct exit surveys as well as an endline survey to assess the contributions of the project, including changes in practices or knowledge of stakeholders. We also plan to produce videos associated with the Hive Planner, two additional podcast episodes, and grower engagement on using the Pollination Planner. Results from this project will also be shared with the Michigan Commercial Beekeepers Association at their meeting in July 2023.
Impacts
What was accomplished under these goals?
Objective 1. Conduct cost-benefit analyses of different honey bee stocking density and placement strategies to develop recommendations for modern blueberry systems. Field experiments were successfully completed for a second year on commercial blueberry farms for the honey bee colony density study (in Michigan only; Florida will be repeated in 2023) and colony placement study (in Michigan, Washington, and Oregon). Pollinators and pollination success have been surveyed, and pesticide exposure data have been collected according to established protocols. Preliminary data analysis was initiated and is ongoing at the time of reporting. Furthermore, economic analyses are in progress and additional revenue and break-even yields that are needed to offset the cost of renting additional hive/s in Michigan and Florida have been estimated. Although current data show that hive placement has no income effects for growers, there may be economic implications for beekeepers for certain hive placements, specifically clumping hives for efficiency and placing pallets such that they face away the field to reduce pesticide exposure. Evaluations of honey bee colony cluster sizes, forager activity, and bee abundance on nearby blueberry flowers were done for fields and colonies under different placement regimes. These colonies were also assessed for other health metrics, including presence of diseases. This information is being used to help understand the link between blueberry pollination contracts and colony diseases. Objective 2. Determine pollination requirements and pollinator attraction across new and existing cultivars. We conducted greenhouse experiments to assess the pollination requirements of 10 southern highbush blueberry cultivars. We conducted a variety of pollination treatments and assessed fruit set, berry weight, berry firmness, brix and acid content of berries, time to ripen, and seed set. We have begun data analysis and presented findings to FL Blueberry Growers Association and the advisory board. Finally, we prepared for the 2023 season in which we will conduct similar experiments with northern highbush blueberries and an additional experiment on the relative attractiveness of different cultivars. Objective 3. Determine how variable weather conditions affect blueberry pollination. We continued to analyze data collected in 2021 to determine the effect of weather on honey bee foraging in the field, as well as controlled laboratory experiments examining the effect of temperature on both the effective pollination period of blueberries and nectar secretion rates. We have begun to write a manuscript on the experimental data for a peer-reviewed publication. Additionally, we monitored weather conditions during bloom in Oregon, Michigan, and Washington as part of activities described under Objective 1b. Pollen germination was measured across a range of temperature conditions in northern highbush cultivars, and this will be repeated in 2023 in southern highbush cultivars. Objective 4. Develop predictive models of pollination, fruit set, and yield for creation of a Pollination Planner to improve pollination management decisions. Planning and refinement of the Pollination Planner continued with attention to the interface, method of deployment, and planned user-inputs and model-outputs for short- (i.e., timing of bloom, honey bee activity by weather, and petal fall) and long-term (i.e., stocking density) planner outcomes. Coordination between Objective 3 and 5 teams continued to inform optimal Pollination Planner design and outputs. Preliminary percent bloom and petal fall prediction models were developed for Michigan and Washington by the Objective 3 team and will be part of future beta-testing of the Pollination Planner. ?Objective 5. Deliver information on improved blueberry pollination to the industry. An online survey about current blueberry pollination practices and challenges was disseminated to blueberry growers between May 2021 and April 2022 through grower meetings and conferences and advertisements in trade journals. We received a total of 539 responses, with 487 responses containing useable data. Majority of responses came from Michigan (30%), while 14% of total was from Florida, 16% from Oregon and 8% from Washington. We wrote an article for the Blueberry News, to be published in late fall 2022, on our preliminary findings in Obj. 1a. Results have been presented to grower commissions in Oregon, Washington, and Florida in 2022. We have also conducted a survey of growers in each region to determine how they would use the Pollination Planner. Our team has also developed two podcast episodes: https://extension.oregonstate.edu/podcast/pollination-podcast/225-chabert-would-blueberry-yield-benefit-planting-different-cultivars and https://extension.oregonstate.edu/podcast/pollination-podcast/192-lisa-devetter-blueberry-pollination-planner

What was accomplished under these goals?
1. Conduct cost-benefit analyses of differenthoney beestocking density and placement strategies to develop recommendations for modern blueberry systems.The Washington team led development of a shared protocol and data templates for sub-objectives 1a-1b with contributions from the entire project team. For subobjective 1a (stocking density), twelvepairedblueberryfarmsacross both Floridaand Michigan were selected (24 total).Half of these farmsreceivedtheaveragehoney bee density treatment, while the other halfreceived either double the average honey beedensitytreatment (in Florida), or an increase of 2 hives per acre than the standard stocking rate (in Michigan). At all farms,honey beevisitation rates were measured on 1or2 cultivars at least 3 times per cultivarduring bloom.Honey beeactivity at the hive (1 min forager counts)was measured on 3-6 occasionsper farm, and cluster counts were performed on a subset of hives at the beginning of the season. Fruit set, weight, and seed set were measured on select branches of 1or2 cultivars per farm, and pollination treatments (open, closed, hand pollinated) were conducted onselect branches of 1or2 cultivars per farm. Additional variables including weather and flowering ground cover were recorded at each farmduring each visit. For sub-objective 1b (placement strategies), the Washington team measured the effects of honey bee hive placement across 12 grower sites, Oregon had 6 sites, and Michigan compared 8 sites. At each site, hives were either placed in a clumped or dispersed pattern. Honey bee visitation, hive activity, and fruit metrics were all measured as described above. Silicone bands were attached to study hives in order to measure pesticide exposure during bloom. These bands are being submitted for pesticide residue analysis. Data analysis was led by the Washington team for sub-objectives 1a (hive density) and 1b (hive placement) for presentation to our advisory board. For 1c (cost-benefit assessment), updating of the baseline enterprise budgets was initiated. 2: Determine pollination requirements and pollinator attraction across new and existing cultivars.Pollination requirements were investigated on7 southern highbush cultivars. Specifically, pollination treatments including no hand pollination, hand self-pollination, and hand cross-pollination were conducted to assess rates of auto fertility andself-fertilityfertilityorself-compatibilityfor each of 7 cultivars. Fruit set, fruit weight, and seed set were measured for all pollination treatmentson each cultivar. Additionally, the length of the effective pollination period was assessed in the cultivar Emerald.These activities generated some interesting preliminaryresults and were effective in refining methods that will be used in future years of the project. 3: Determine how variable weather conditions affect blueberry pollination.In Florida, the effect of temperature on the effective pollination period of the southern highbush cultivar Emerald was investigated by conducting pollination experiments under 12 C and 29 C temperature treatments. Additionally, nectar secretion rates over time were examined under different temperature treatments for the cultivar Emerald.In Michigan, the effect of extreme heat on blueberry pollen germination and pollen tube growth was investigated in vitro on several common northern highbush cultivars, including Bluecrop, Jersey, Liberty, and Elliott. Temperatures used in experiments ranged from 10 - 37.5 C and were assessed at 4 and 24 hours after exposure to heat treatments. A manuscript is in progress to publish these results, and more varieties will be tested using these same methods in 2022.Furthermore, during field data collection for objective 1 (stocking and hive placement effects), we also collected weather data immediately before and after measuring honey bee foraging in blueberry fields. We sampled across a range of environmental conditions to capture representative environmental variations in our field conditions. Environmental data collected included: temperature, relative humidity, barometric pressure, cloud cover, irradiance, and wind speed. Analysis of this data will help determine how weather conditions effect bee activity and successful pollination. 4: Develop predictive models of pollination, fruit set, and yield for creation of a Pollination Planner to improve pollination management decisions.Data from objectives 1-3 was delivered to collaborators in order to be incorporated into Objective 4's predictive models.A draft Pollinator Planner interface was developed and the interface was shared with meteorologists and our advisory board for feedback. 5: Deliver information on improved blueberry pollination to the industry.Information was delivered at a field day in Oregon with co-PIs Melathopoulos and Devetter. The whole team was able to share information via our project Twitter account (@BeesNBerries). A project website was developed to share project updates and relevant materials. On this website, we are publishing a regular newsletter that stakeholders can subscribe to. Team members from Oregon and Washington also contributed to two PollinNation podcasts on berry crop pollination.A survey was created for impact assessment and was distributed to blueberry growers across the country. Melathopoulos developed a card and infographic to promote responses to our grower survey. The draft Pollination Planner from Objective 4 was prepared for our fall advisory board meeting where we received feedback from members on the board. In Florida and Washington, individual grower reports were provided to all participating farms. These reports provided farm-specific data collected under Objective 1.
