摘 要：With climate change,the spotted-wing Drosophila(SWD,Drosophila suzukii)invades a great number of fruit production regions worldwide.A plethora of insecticides are being applied for management of this *** expected,SWD develops resistance against some potent insecticides or is rather insensitive to some ***,there is an urgent need to identify and characterize alternative insecticides to control SWD ***,we have studied the effects of the orally applied inhibitor of the fatty acid synthesis pathway spirotetramat on SWD fitness with respect to fecundity and surface barrier function at different *** our experiments,we applied spirotetramat mixed with baker s yeast and showed that females and males were not repelled by effective concentrations of this *** found that spirotetramat,by trend,lowers egg numbers laid by fed *** eggs rapidly desiccate,and only a few larvae *** is lethal to larvae and reduces survival of adult flies under low-humidity *** together,based on our data,we propose to use yeast supplemented with spirotetramat and additional SWD-specific attractants in traps in non-crop areas in order to eradicate SWD populations before they infest crop production sites.
