Non Technical Summary
Blueberries are one of the major fruit crops in the state of Georgia with farm gate value of $227 million andan overall economic impact of over $1 billion on the state economy. Historically, blueberries have had very few insect pest problems in Georgia, however, an invasive vinegar fly commonly known as spotted-wing drosophilahas emerged as a major threat toblueberry production in the Georgia. Crop losses due to this pest have been reportedto be 15-20% annually and in some cases it can be as high as 100% crop loss.Due to zero tolerance in the market, frequent applications of broad-spectrum insecticides is the primary means to control this pest. This approach is not sustainable and can have hazardous effects on human health and the environment andlead toresistance developmnent in this pest. Additionally, frequent applications of broad-spectrum insecticides can be lethal to beneficial insects leading to increase in secondary pest problems. Recent growerreports have already indicated increasing infestations of secondary pests such as scales, gall midge, thrips, and bud mites.The goal of this project is to help growers develop sustainable integrated pest management (IPM)programs to manage the economically important pests of blueberries. This goal will be achieved under the following objectives: 1)understand biology and ecology of economically important pests of blueberries;2) evaluate existing and new pest management technologies to determine their efficacy and optimize their use in season-long management programs; and3) disseminate this information to growers. This will help increase grower knowledge and implementation of IPMstrategies to control insect pests in blueberries which will decreasetotal use of broad-spectrum pesticidesand increase grower profitability.

Progress 10/01/20 to 09/30/21

Outputs
Target Audience:Blueberry farmers, processors, packing shed owners, and pest management consultants. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Due to COVID-19 in-person extension meetings were limited. However, during this reporting period several training and professional development opportunities were offered. Two graduate students, two postdocs, and three undergrad students were trained on applied research through this project. Many county extension agents, crop consultants, and growers were trained through extension and education presentations. How have the results been disseminated to communities of interest?The results were disseminated through research and extension publications in journals, extension publications and grower magazine, website articles, blog posts on UGA blueberry blog, UGA IPM blog, and presentations at grower and professional meetings. What do you plan to do during the next reporting period to accomplish the goals?We plan to continue investigating biology and ecology of economically important insect pests of blueberries, evaluate & optimize novel management strategies, and disseminate new scientific information to farmers and other stakeholders to educate them on best ways to effectively control insect pests and minimize crop losses due to insect pests.

Impacts
What was accomplished under these goals? During this reporting period multiple studies were conducted in the field and laboratory to understand biology and ecology of economically important insect pests of blueberries including spotted wing drosophila and flower thrips. For spotted-wing drosophila, studies were conducted to compare yeast-sugar-water based wet traps with the red panel dry traps baited with commercially available lures. Results showed that dry traps had comparable trap captures of SWD adults. In other trials, we evaluated efficacy of new reduced risk insecticides in season-long SWD management programs. The new product Gemsei when applied at the high rate of 48 fl oz resulted in significantly higher mortality as compared to the untreated control. These findings were disseminated to blueberry growers and used to update SWD management recommendations. Initial laboratory and semi-field trials were conducted to evaluate new behavioral control technologies including ACTTRA and Combi-protec. Further studies will be conducted to determine the best use of these products to manage SWD in GA blueberry production systems. Blueberry flower thrips have emerged as a major pest problem in GA blueberries. Thrips management is particularly challenging because direct insecticide sprays can harm pollinators active in the field during bloom time when thrips are feeding on blooms. Field trials were conducted to evaluate new reduced risk systemic materials to determine their efficacy when applied prior to bloom to minimize their impact on pollinators. These data are still being analyzed and findings will be disseminated to blueberry growers as soon they are ready.

Impacts
What was accomplished under these goals? Several studies were conducted in the field and laboratory to understand biology and ecology of economically important insect pests of blueberries inclding spotted wing drosophila and southern red mite. Based on trap captures and farmer reports,spotted wing drosopphila populations were active during the blueberry harvest but farmers implemented management programs recommended by UGA extension specialists and as a result not fruit rejections were reported.A heavy infestation of southern red mite was detected at a blueberry farm in Adkisson county. I field trial was conducted at that site evaluate new miticides, and findings were disseminated via research publications and extension presentations
