“…In addition to its well-known lethal effects (e.g. Gutiérrez et al 2017;Shaw et al 2019;Vander Pan et al 2019), sublethal concentrations of deltamethrin can entail major physiological damages in a multitude of target and non-target insects (Cutler, 2013;Müller, 2018). For instance, exposure to sublethal doses of deltamethrin reduces females' fecundity in honeybees, parasitoid wasps and cockroaches (Dai et al, 2010;Lee et al, 1998;Teder and Knapp, 2019), impairs larval development in honeybees and the wasp Trichogramma achaeae (Oliveira et al, 2018;Yang et al, 2020) and inhibits molting processes in the stable fly Stomoxys calcitrans (Reissert-Oppermann et al, 2019).…”

The application of pesticides typically leads to lethal and sublethal exposure of non-target insects. Whereas our current understanding of these sublethal effects typically focuses on reproductive and physiological parameters, recent works emphasize that sublethal effects on behaviors such as maternal care could be of major importance in non-target species. However, it remained unknown whether these sublethal effects occur in insects. Here, we tested if exposure to sublethal doses of deltamethrin -a pyrethroid insecticide commonly used in crops -alters the expression of maternal egg care in females of the European earwig Forficula auricularia, a predator insect and pest control. Our results first reveal that deltamethrin exposure impaired the expression of three forms of maternal egg care: It decreased the likelihood of mothers to gather their otherwise scattered clutch of eggs, increased the time during which the female abandoned the clutch after a predator attack and reduced egg grooming duration. These sublethal effects did not reflect a lower activity of deltamethrin-exposed females, as these females increased their expression of self-grooming, and deltamethrin exposure did not affect females' exploration and mobility. Finally, we found that the negative effects of deltamethrin on egg care did not modify egg development, hatching rate and juvenile weight, possibly due to the transient effects of deltamethrin on maternal behaviors. Overall, our results reveal that sublethal exposure to a pesticide may diminish maternal egg care in a natural pest control and call for the integration of this measurement in assays on pesticides application.

“…Deltamethrin and cypermethrin are both pyrethroids with a known direct contact activity against D. suzukii adults. [37][38][39] In our trials a 15 mg-containing deltamethrin lid and a 350 mg-containing cypermethrin ring were used as killing agent. In a recent study in which deltamethrin and cypermethrin were included with a comparable difference in dose rate (1 g deltamethrin per 100 L and 21 g cypermethrin per 100 L), deltamethrin was shown to cause a faster mortality of SWD adults (90%, 100% and 100% Abbott efficacy at 1, 2 and 3 days post-treatment) than cypermethrin (74%, 98% and 100% Abbott efficacy).…”

Background Spotted wing drosophila (SWD), Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is a pest of stone and small fruits causing considerable economic losses. Current management strategies rely primarily on calendar‐based spraying, owing to the poor relationship between monitoring data and damage levels, and the lack of success of mass‐trapping tools. The aim of this study was to evaluate different trap models for SWD, with an emphasis on their fly‐retention capacity. To this end, we examined and quantified the added value of two fly‐retaining trap features; tunnel entries to impede escape and an insecticide‐coated inner surface as a killing agent. Results An insecticide‐coated inner surface resulted in significantly higher trap retention after 24 h in the laboratory (4.9‐ to 7.4‐fold greater, depending on trap type) compared to a noncoated trap. Trapping efficacy was significantly improved in field trials by such a killing agent in the trap (1.2‐ to 4.5‐fold greater). Tunnel entries significantly improved trap retention in the laboratory and field (by 1.5‐fold). Conclusion The outcomes of this study clearly reveal the substantial impact of the fly‐retention capacity of SWD traps on their overall capture performances. It was demonstrated for the first time that an insecticide‐coated inner surface as a killing agent significantly improves trap efficacy for SWD. This finding can readily be implemented in any trap model to improve monitoring and mass trapping of SWD. Also tunnel entries were shown to have a significant influence on the fly retention and, hence, substantially enhance trapping efficacy.

“…Spinosad is a widely used crop protection agent for the control of SWD derived from a compound biosynthesized by Saccharopolyspora spinose (Shaw et al, 2019). We examined whether supplementation with saccharin might enhance the insecticidal activity of spinosad (Table 2).…”

The purpose of this study was to develop a new control method for Drosophila using saccharin sodium dihydrate (saccharin), an artificial sweetener that is safe for humans and the environment, and to elucidate its mode of action. In this study, we confirmed that saccharin can dose-dependently inhibit the development of or kill vinegar flies (VFs) and spotted wing Drosophila (SWDs). In addition, we found that low concentrations of saccharin induced a similar effect as starvation in Drosophila, whereas high concentrations of saccharin induced changes in the unfolded protein response (UPR) and autophagy signaling that were unlike starvation and inhibited development or killed the VF and the SWD by performing realtime quantitative polymerase chain reaction analyses. Spinosad is a widely used plant protection agent for SWD control.When saccharin was cotreated with 0.25-1.0 ppm spinosad, an additive insecticidal activity was observed only at high concentrations of saccharin. However, when saccharin was cotreated with 2.0 ppm spinosad, an additive insecticidal activity was observed at low concentrations of saccharin. Taken together, alteration of UPR and autophagy signaling represented the molecular basis underlying saccharin toxicity to
