After laying a single egg, weevils will girdle or “clip” the buds at the pedicel, killing the bud and preventing fruit development. This injury is of concern to commercial strawberry growers, who typically assume the loss of one clipped bud is the loss of one average sized fruit, causing the economic threshold to be set extremely low. There is evidence of compensation in some cultivars of strawberries, but research has previously only been conducted in perennial strawberry production. The majority of strawberries in the southeastern United States are grown in annual plasticulture systems. We assessed the ability of five strawberry cultivars commonly grown in annual plasticulture to compensate for A. signatus injury by removing buds at different growth stages. There was no effect of bud removal on total yield in any of the cultivars tested. Harvest timing was affected by simulated A. signatus damage in some cultivars, which may be an important consideration for direct market strawberry growers.}, number={1}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={McPhie, Douglas and Burrack, Hannah J.}, year={2017}, month={Feb}, pages={208–212} }

Although much effort has been directed toward developing traps and attractants to monitor for D. suzukii, current monitoring tools do not reliably predict fruit infestation. The objective of this study was to determine if D. suzukii females at different developmental stages are differentially attracted to monitoring traps with fermentation-based baits and ripe fruits. Females were collected on the surface of traps, within traps, and on ripe fruits during three experiments at field locations in North Carolina, USA, and were dissected to determine their reproductive status. In general, females collected on ripe fruits were more likely to have mature eggs present in their ovaries and had higher numbers of mature eggs than females collected on the surface of or within monitoring traps. The results of this study have implications for D. suzukii monitoring and the development of effective baits for use in integrated pest management programs.}, number={4}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Swoboda-Bhattarai, Katharine A. and McPhie, Douglas R. and Burrack, Hannah J.}, year={2017}, month={Aug}, pages={1648–1652} }

Female A. signatus cause injury to the host plant during egg laying when they deposit a single egg inside an unopened flower bud and then girdle or “clip” the bud at the pedicel. Past efforts to control A. signatus populations have relied on the use of broad spectrum insecticides. Fields are either treated at the first signs of damage, or precautionary treatments may be applied prophylactically in fields with a history of damage. Because A. signatus damage occurs during bloom, there is concern about the potential harm to pollinators caused by these treatments. In order to identify materials more compatible for use during bloom, the efficacy of reduced risk pesticides against A. signatus was tested in semi-field bioassays over two years. Beauveria bassiana, cyantraniliprole, novaluron, and pyrethrins were assessed in the first year, and none caused significant A. signatus mortality. Acetamiprid, flonicamid, and spinosad were compared in the second year, acetamiprid and spinosad had higher A. signatus mortality than an untreated control, and exposure to spinosad resulted in similar mortality to bifenthrin, an industry standard material.}, journal={CROP PROTECTION}, author={McPhie, Douglas and Burrack, Hannah J.}, year={2016}, month={Nov}, pages={255–258} }

 Drosophila suzukii Matsumara, also referred to as the spotted wing drosophila, has recently expanded its global range with significant consequences for its primary host crops: blueberries, blackberries, raspberries, cherries, and strawberries. D. suzukii populations can increase quickly, and their infestation is difficult to predict and prevent. The development of effective tools to detect D. suzukii presence in new areas, to time the beginning of activity within a crop, to track seasonal activity patterns, and to gauge the effectiveness of management efforts has been a key research goal. We compared the efficiency, selectivity, and relationship to fruit infestation of a range of commonly used homemade baits and a synthetic formulated lure across a wide range of environments in 10 locations throughout the United States. Several homemade baits were more efficient than apple cider vinegar, a commonly used standard, and a commercially formulated lure was, in some configurations and environments, comparable with the most effective homemade attractant as well as potentially more selective. All alternative attractants also captured flies between 1 and 2 wk earlier than apple cider vinegar, and detected the presence of D. suzukii prior to the development of fruit infestation. Over half the Drosophila spp. flies captured in traps baited with any of the attractants were not D. suzukii, which may complicate their adoption by nonexpert users. The alternative D. suzukii attractants tested are improvement on apple cider vinegar and may be useful in the development of future synthetic lures.}, number={3}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Burrack, Hannah J. and Asplen, Mark and Bahder, Luz and Collins, Judith and Drummond, Francis A. and Guedot, Christelle and Isaacs, Rufus and Johnson, Donn and Blanton, Anna and Lee, Jana C. and et al.}, year={2015}, month={Jun}, pages={704–712} }
