Abstract:
... Extracellular vesicles (EVs) have been reported to be secreted from Schistosoma japonicum at all developmental stages. However, the reproduction and communication mechanisms between the paired adults through the EVs in dioecious Trematoda have not been reported. In this study, EVs containing many exosome-like vesicles and microvesicles were observed in the supernatants of paired adults cultured in ...

Abstract:
... Life‐history traits determine individual fitness and the fate of populations. Imidacloprid, a widely used neonicotinoid insecticide, which persists in soil for more than 100 d at biologically relevant levels, may affect nontarget and ecologically important species, such as collembolans. In the present study, we determined the sublethal effects of short‐term imidacloprid exposure and postexposure r ...

Abstract:
... Fenoxycarb, a juvenile hormone agonist has been widely used to control various insect pests in agriculture. Fenoxycarb has been considered environmentally safe because it degrades quickly and has lower mammalian toxicity compared with many conventional pesticides. To date, fenoxycarb is reported safe for soil organisms, but this conclusion is based solely on toxicity studies with Folsomia candida ...
