Published: July 26, 2021

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 markets, frozen berries, export programs have been impacted due zero tolerance for infestation. As control rely heavily on insecticides, exceedance maximum residue levels (MRLs) resulted in crop rejections. The impact particularly severe organic operations, mainly limited availability effective insecticides. Integrated management (IPM) could significantly reduce chemical inputs but would require substantial changes horticultural practices. This review evaluates most promising methods studied part an IPM strategy against across world. For each considered techniques, effectiveness, impact, sustainability, stage development are discussed.

Abstract Asobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids’ capacity to attack develop from 24 non-target drosophilid species. Results showed that all three were able parasitize host larvae multiple species in artificial diet; A. developed 19 tested species, regardless the phylogenetic position L. 11 species; G. only four exposed Success rate parasitism (i.e., probability an adult wasp successfully emerged a parasitized host) by two figitid was low hosts other than melanogaster group ( D. , simulans ). The failure figitids most appears correspond with more frequent encapsulation hosts. results indicate is specific attacks mainly generalist, at least physiologically. Overall, developmental time increased host’s time. body size female (as model species) positively related size, mature egg load wasps size. We discuss use for classical biological control .

Abstract The spotted wing drosophila, Drosophila suzukii Matsumura, is an insect pest of soft-skinned fruit, native to Eastern Asia. Since 2008, a world-wide dispersal D. seen, characterized by the establishment in many Asian, American and European countries. While potential for invasion continental Africa has been predicted, its presence only shown Morocco Northern Africa. Knowledge about possible other parts continent needed as basis management. In 2019, we carried out first survey three counties Kenya monitor using traps baited with blend apple cider vinegar red wine. A total 389 flies were captured fruit farm at Nakuru county, more female being trapped than males. We confirmed morphological identification DNA barcoding. 2020, performed follow-up 14 locations six delimit distribution main berry growing zones Kenya. indicated that so far restricted county where it was initially detected.

The strawberry crop endures economic losses due to feeding injury from a number of phytophagous arthropod pests. A invasive pests have posed challenges protection techniques in the cropping system recently. It is increasingly evident that sole reliance on chemical control options not sustainable. In this review, current and advances integrated pest management various are presented. Key discussed include thrips, mites, lygus bug, spotted wing drosophila, seed weevils, aphids, whiteflies, armyworms. Several use intercropping, resistant cultivars, irradiation with gamma rays, spectral sensitivity pests, biological agents natural enemies, biorational pesticides recently been reported be useful managing With increase world production strawberry, several will necessary manage complex strawberry.

Sublethal effects of nine insecticides on Drosophila suzukii and its major pupal parasitoid Trichopria drosophilae

Pest Management Science, Journal Year: 2023, Volume and Issue: 79(12), P. 5003 - 5014

Published: Aug. 7, 2023

Although the pupal parasitoid Trichopria drosophilae is used in conservative and augmentative biocontrol of Drosophila suzukii infestations, current pest management strategies mostly rely on multiple insecticide applications. In this context, aim study was to investigate baseline toxicity nine insecticides D. larvae their sublethal effects (LC10 ) immature stages feeding contaminated diet T. developing within intoxicated host.Chlorpyriphos azadirachtin showed lowest highest LC10 , values which were 9.78 × 1013 1.46 103 times lower than recommended label field rate, respectively. Among tested insecticides, imidacloprid, malathion dimethoate only treatments that did not affect juvenile development time suzukii, while spinosad organophosphates chlorpyriphos influence fly size. No recorded degree infestation (DI) time. On contrary, cyazypyr negatively affected success parasitism (SP) number progeny parasitoid, association with for first parameter fertility.

Factors influencing oviposition behaviour of the invasive pest, Drosophila suzukii, derived from interactions with other Drosophila species: potential applications for control

Pest Management Science, Journal Year: 2023, Volume and Issue: 79(11), P. 4132 - 4139

Published: July 30, 2023

Drosophila suzukii (Matsumura) or spotted wing is a worldwide invasive pest of soft- and stone-fruit production. Female D. lay their eggs in ripening fruit the hatched larvae damage from inside, rendering it unmarketable causing significant economic loss. Current methods to reduce population field primarily rely on chemical insecticides which are not sustainable long-term solution increase risk resistance developing. Several studies demonstrate that when encounter coexist with other food source, this usually disadvantage suzukii, leading reduced oviposition increased larval mortality. These effects have potential be exploited management perspective. In review we summarise recent research articles focusing interspecific interactions between species aimed at understanding how drives behaviour. Potential semiochemical microbiome impacts postulated as determinants Development control practices reducing populations deterring them laying by utilising factors drive behaviour discussed. © 2023 The Authors.

Coordinated molecular and ecological adaptations underlie a highly successful parasitoid

eLife, Journal Year: 2024, Volume and Issue: 13

Published: April 23, 2024

The success of an organism depends on the molecular and ecological adaptations that promote its beneficial fitness. Parasitoids are valuable biocontrol agents for successfully managing agricultural pests, they have evolved diversified strategies to adapt both physiological condition hosts competition other parasitoids. Here, we deconstructed parasitic in a highly successful parasitoid, Trichopria drosophilae , which parasitizes broad range Drosophila hosts, including globally invasive species D. suzukii . We found T. had developed specialized venom proteins arrest host development obtain more nutrients via secreting tissue inhibitors metalloproteinases (TIMPs), as well unique type cell—teratocytes—that digest tissues feeding by releasing trypsin proteins. In addition optimize nutritional uptake, this pupal parasitoid has ecologically adaptive conditional tolerance intraspecific enhance older obligate avoidance interspecific with larval Our study not only demystifies how parasitoids weaponize themselves colonize formidable but also provided empirical evidence intricate coordination between drive evolutionary success.
