Over two growing seasons, we compared D. control research planting with insecticide exclusion treatments factorial design, monitoring...
Abstract BACKGROUND The invasive drosophilid pest, Drosophila suzukii Matsumura, is affecting berry production in most fruit‐producing regions of the world. Chemical control dominant management approach, creating concern for insecticide resistance this pest. We compared susceptibility D. populations collected from conventional, organic or insecticide‐free blueberry sites. RESULTS sensitivity to malathion and spinetoram declined slightly across 3 years monitoring, whereas it was more...
Drosophila suzukii Matsumura (Diptera: Drosophilidae) has become a major economic pest of soft-skinned fruits since it was detected in North America 2008. Control this fly is achieved through insecticide sprays applied when ripening or ripe fruit are present. Monitoring to aid informed management decisions challenging trapping for adults not reliable indicator potential existing infestation the fruit. Moreover, current larval monitoring techniques using brown sugar salt solutions allow...
Abstract Spotted‐wing drosophila, Drosophila suzukii (Matsumura), is an invasive pest affecting fruit production in many regions of the world. Insecticides are primary tactic for controlling D. organic as well conventional systems. Organic growers have a greater challenge because fewer insecticides approved use agriculture. The most effective organically product spinosad, but alternatives needed label restrictions limiting number applications per year, toxicity to beneficial arthropods and...
Spotted wing Drosophila is an invasive pest of fruit crops in most production regions globally, and insecticides are commonly used for its control. The biology this combined with repeated pesticide exposure increases the risk resistance to insecticides. We tested malathion, methomyl, spinetoram, spinosad, zeta-cypermethrin against multiple colonies from each state using a contact bioassay method determine diagnostic doses assessment insecticide susceptibility species. These were test...
Abstract Drosophila suzukii, or spotted-wing drosophila, is now an established pest in many parts of the world, causing significant damage to numerous fruit crop industries. Native East Asia, D. suzukii infestations started United States a decade ago, occupying wide range climates. To better understand invasion ecology this pest, knowledge past migration events, population structure, and genetic diversity needed. In study, we sequenced whole genomes 237 individual flies collected across...
Abstract D rosophila suzukii is a new invasive pest that in recent years has become established the G reat L akes region of U nited S tates. Understanding level infestation potentially susceptible crops an important first step for planning appropriate management responses. This study was conducted 2010–2012 to determine potential this native V itis labrusca , F rench hybrid and . vinifera grape cultivars grown Michigan vineyards. adults were reared out collected samples all 3 years,...
Fruit growers largely depend on chemical control to reduce populations of the economically damaging invasive fly, Drosophila suzukii (Matsumura). is susceptible high temperatures and low humidity; therefore, it may be possible implement cultural practices that create microclimates unfavorable for its development survival. In addition other fruit production benefits, in-row mulches impede D. immatures when larvae leave pupate in soil. This study compared effects different (black polypropylene...
Invasive insect pests can be challenging to manage because their recent arrival provides limited information on which build predictive population models. The magnitude and timing of activity by the invasive vinegar fly, Drosophila suzukii, in crop fields has been unpredictable due its many new regions world changes methods for detection. Using 7 yr consistent trapping adults at four blueberry farms Michigan, United States, we modeled temporal environmental factors influencing D. suzukii...
The invasive spotted-wing drosophila, Drosophila suzukii (Matsumura), is a major pest of soft-skinned fruits. Since its introduction into North America and Europe, significant progress has been made in understanding the volatile cues used by this fly during food, oviposition site, mate finding. Despite progress, commercially available lures are non-selective. Here, we tested two Hanseniaspora uvarum (Niehaus) yeast compounds (isoamyl acetate isobutyl acetate) leaf compound β-cyclocitral...
Abstract Biological control of Drosophila suzukii may be enhanced through adventive populations the figitid parasitoid Leptopilina japonica (Novković & Kimura) (Hymenoptera: Figitidae). This insect has expanded its range considerably but we have limited understanding phenology, wild host plant associations, and response to fruit crop management this parasitoid. To address these gaps, samples were collected in managed habitats across southern Michigan, placed on metal mesh a plastic...
Abstract Spotted‐wing drosophila, Drosophila suzukii Matsumura, is an invasive pest in the United States that causes considerable damage to fruit crops.
