Abstract BACKGROUND The spotted wing drosophila ( SWD ), Drosophila suzukii (Matsumura), is an invasive vinegar fly with a preference for infesting commercially viable berries and stone fruits. infestations can reduce yields significantly, necessitating additional management activities. This analysis estimates economic losses in the California raspberry industry that have resulted from invasion. RESULTS producers experienced considerable revenue costs first years following 's invasion of...
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) also known as spotted-wing drosophila (SWD), is a pest native to Southeast Asia. In the last few decades, has expanded its range affect all major European and American fruit production regions. SWD highly adaptive insect that able disperse, survive, flourish under of environmental conditions. Infestation by generates both direct indirect economic impacts through yield losses, shorter shelf life infested fruit, increased costs. Fresh...
A rich history of investigation documents various Drosophila-yeast mutualisms, suggesting that Drosophila suzukii similarly has an association with a specific yeast species or community. To discover candidate species, yeasts were isolated from larval frass, adult midguts, and fruit hosts D. suzukii. Terminal restriction fragment length polymorphism (TRFLP) technology decimal dilution plating used to identify determine the relative abundance present in juice samples either infested not...
Abstract Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of wide variety fruit crops in the United States as well Europe, leading to substantial yearly crop losses. To enable basic and applied research this important pest, we sequenced D. genome obtain high-quality reference sequence. Here, discuss properties transcriptome describe patterns evolution its close relatives. Our analyses annotations are presented web portal, SpottedWingFlyBase,...

Abstract Drosophila have evolved strong mutualistic associations with yeast communities that best support their growth and survival, resulting in the development of novel niches. It has been suggested flies recognize cognate yeasts primarily based on rich repertoire volatile organic compounds (VOCs) derived from yeasts. Thus, it remained an exciting avenue to study whether fly spp. detect discriminate strains odor alone if so, how such resolution is achieved by olfactory system flies. We...
Drosophila suzukii causes economic damage to berry and stone fruit worldwide. Laboratory-generated datasets were standardized combined on the basis of degree days (DD), using Gompertz Cauchy curves for survival reproduction. Eggs transitioned larvae at 20.3 DD; pupae 118.1 adults 200 DD. All are expected have died 610 Oviposition initiates 210 DD gradually increases a maximum 15 eggs per 410 subsequently decreases zero These data used as cohort-level population model. Laboratory under...
In recent years, there has been an increase in the adventive establishment and spread of parasitoid wasps outside their native range. However, lack taxonomic tools can hinder efficient screening field-collected samples to document range expansion parasitoids on continent-wide geographic scales. Here we report that Leptopilina japonica (Hymenoptera, Figitidae), a globally invasive fruit pest Drosophila suzukii (Diptera, Drosophilidae), is now widespread much North America despite not having...
Drosophila suzukii (Matsumura), an invasive pest of small and stone fruits, has been recently detected in 39 states the United States, Canada, Mexico, Europe. This attacks ripening fruit, causing economic losses including increased management costs crop rejection. Ongoing research aims to improve efficacy monitoring traps. Studies were conducted evaluate how physical trap features affect captures D. suzukii. We evaluated five colors, two bait surface areas, a top side position for fly entry...
Native to Southeast Asia, Drosophila suzukii (Matsumura) is a recent invader that infests intact ripe and ripening fruit, leading significant crop losses in the U.S., Canada, Europe. Since current D. management strategies rely heavily on insecticide usage detoxification gene expression under circadian regulation closely related melanogaster, we set out determine if integrative analysis of daily activity patterns can predict chronotoxicity insecticides. Locomotor assays were performed...
Native to Southeast Asia, Drosophila suzukii (Matsumura) prefer oviposit on ripe fruit and have become an important pest of California raspberries (Rubus idaeus L.) since their detection in Santa Cruz County, CA, 2008. Preliminary management guidelines included D. monitoring recommendations, though there was little available information seasonal occurrence potential lures for use raspberries. To address this issue, we trapped adult weekly 2 yr (including both spring fall harvests) multiple...
Transgenic corn and cotton that produce Cry Vip3Aa toxins derived from Bacillus thuringiensis (Bt) are widely planted in the United States to control lepidopteran pests. The sustainability of these Bt crops is threatened because earworm/bollworm, Helicoverpa zea (Boddie), evolving a resistance toxins. Using sweet as sentinel plant monitor evolution resistance, collaborators established 146 trials twenty-five states five Canadian provinces during 2020–2022. study evaluated overall changes...
Abstract As part of an insect resistance management plan to preserve Bt transgenic technology, annual monitoring target pests is mandated detect susceptibility changes toxins. Currently Helicoverpa zea (Boddie) involves investigating unexpected injury in crop fields and collecting larvae from non-Bt host plants for laboratory diet bioassays determine mortality responses diagnostic concentrations To date, this approach has not detected any significant change the known range baseline toxins,...
Abstract Larval Drosophila encounter and feed on a diverse microbial community within fruit. In particular, free-living yeast microbes provide source of dietary protein critical for development. However, successional changes to the fruit may alter host quality through impacts relative content or composition. For many species , fitness benefits from feeding vary between individual species, indicating differences in nutritional quality. To better understand these associations, we evaluated how...
Replacing synthetic insecticides with transgenic crops for pest management has been economically and environmentally beneficial, but these benefits erode as pests evolve resistance. It proposed that novel genomic approaches could track molecular signals of emerging resistance to aid in management. To test this, we quantified patterns change Helicoverpa zea, a major lepidopteran target Bacillus thuringiensis (Bt) crops, between 2002 2017 both Bt crop adoption increased North America. Genomic...
Abstract BACKGROUND Field corn production systems rely on preventative insect management tactics, including hybrids expressing plant‐incorporated protectants that are treated with neonicotinoid seed treatments and sometimes in‐furrow pyrethroids. While effective seedling pest control can be crucial because of the cost replanting, these target many same pests may add unnecessary costs for growers. Furthermore, in Mid‐Atlantic tend to sporadic, insecticides negatively impact natural enemies....
Drosophila suzukii Matsumura (Diptera: Drosophilidae) is an agricultural pest with a wide host range. It known to infest fruit that are still ripening on the plant, as well rotting and damaged fruit. Our study sought determine whether D. use mulberries (Morus spp.) figs (Ficus carica (L.)) hosts, their status was ambiguous. Accordingly, we collected 25 field-infested counted numbers of emerging from them. We also female would respond olfactory cues ripe mulberries. As population has been...
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...
The invasive vinegar fly, Drosophila suzukii Matsumura, has emerged as one of the most serious arthropod pests primocane red raspberries (Rubus ideaus L.) in United States. In raspberries, D. encounter a diverse community microbes, including fruit rot pathogens such Botrytis cinerea Pers and Cladosporium cladosporioides de Vries. this study, our primary objectives were to evaluate suzukii-fungal associations determine suzukii's influence on fungal communities raspberry fruit.
