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...
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...
Spotted wing drosophila, Drosophila suzukii, is a globally invasive pest of soft-skinned fruit. Females oviposit into ripening fruit and larvae cause direct destruction tissues. As many plant essential oils are permitted food additives, they may provide safe means protecting from D. suzukii infestation in both conventional organic production systems. Twelve potassium metabisulfite (KMS) were screened the laboratory as repellents for flies. Most deterred flies cotton wicks containing...
A new aleocharine rove beetle, Pella glooscapi Klimaszewski & Majka, sp. n., from Nova Scotia, Canada, is described and illustrated. Data on bionomics distribution are provided. short diagnosis, description, colour body image, black white genital images also It appears to be closely related P. criddlei (Casey). loricata (Casey), Zyras obliquus Dalotia coriaria (Kraatz) newly recorded for Atlantic Canada as a whole.
Drosophila suzukii Matsumura (Diptera: Drosophilidae) is a recent invasive pest of fruit crops in North America and Europe. Carpophagous larvae render unmarketable may promote secondary rot-causing organisms. To monitor spread develop programs to time application controls, further work needed optimize trap design trapping protocols for adult D. suzukii. We compared commercial traps developed new, easy-to-use plastic jar that performed well with other designs. For some types, increasing the...
Abstract Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive, early-season pest of strawberry in Florida, causing feeding injury to young foliage that results stunted plant growth and yield loss. Spinetoram, effective insecticide for thrips pests with up 3 applications per season permitted strawberry, often applied repeatedly during the (Oct–Nov) manage S. dorsalis, leaving few or no flower later (Dec–Mar). Therefore, new strategies are needed less insecticide, hypothesis...
Drosophila suzukii Matsumura is an economically important pest of soft and small fruit crops. Unlike other drosophilid flies, D. capable infesting ripe partially fruit, which poses a significant management challenge, as there no tolerance for infested or damaged in the marketplace. As result, producers many regions rely on calendar-scheduled insecticide applications management. In order to develop integrated approach, better tools monitoring adult fly populations are needed. Over two growing...
Drosophila suzukii (Matsumura) is a recent invasive pest of soft fruits in North and South America Europe. Control relies on frequent applications synthetic insecticides. Additional tactics are needed for development an effective integrated management program. Study objectives were to evaluate the repellency oviposition deterrent capability compounds plant essential oils effect select infestation rates strawberries, using laminate polymer flakes as carrier. Of 14 from 5 oils, thymol was most...
Drosophila suzukii is an invasive pest and economic threat to berry crops in Europe the Americas. Current methods of control this rely primarily on frequent applications insecticides; therefore, there a need for alternative reduce insecticide reliance. In study, we evaluated biological potential three parasitoid wasps: Diglyphus isaea, Muscidifurax raptorellus Pachycrepoideus vindemmiae, four predators: Chrysoperla carnea, Dicyphus hesperus, Orius insidiosus Podisus maculiventris....
Abstract The Carabidae (Coleoptera) are a diverse family of beetles with almost 300 species identified in Nova Scotia, Canada. Carabid beetle communities have been studied several agricultural systems, but not wild blueberries, an important crop eastern In the interest potentially developing conservation biological control programs blueberry, we collected (fruit-bearing) and sprout (vegetative) blueberry fields Scotia order to assess diversity abundance over space time. Over 3200 specimens...
The twospotted spider mite (Tetranychus urticae) is a serious pest of strawberries. objectives this study were to determine incidence and severity infestations on transplants the potential for steam eliminate them. Mites occurred Florida cultivars from each eight North American nurseries which samples obtained, but levels usually low (59% had zero mites). Estimated complete mortality adult females eggs leaf discs using at 48°C was 2.7 1.9 h, respectively; 44°C 46°C up 4 h killed 20% 60%...
Since it inhabits young leaves and buds of strawberry (Fragaria × ananassa Duchesne) crowns, cyclamen mite (Phytonemus pallidus Banks) is a difficult pest to control with biological or chemical means once present in field. Controlled atmosphere temperature treatment (CATT) successful technique that has been commercially used the Netherlands for nearly 2 decades disinfect nursery stock, including elimination mite. During CATT, plants are treated at 35 °C, 50% CO2, 10% O2 under high relative...
Cyclamen mite is a pest of strawberry that difficult to control due its small size and preference for inhabiting concealed spaces in new plant growth. Steam treatment transplants effectively reduces some pathogens may be valuable tool against cyclamen mite. Strawberry ("Jewel" "Annapolis") were artificially infested with steam-treated at 44°C 1 h or 48°C 0.5 h. Both treatments reduced numbers by > 99% compared the control, had no negative effects on survival, growth yield. In second,...
