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.

Insect-specific neurotoxic peptides derived from the venoms of scorpions and spiders can cause acute paralysis and death when injected into insects,offering a promising insecticidal component for insect pest ***,effective delivery systems are required to help neurotoxic peptides pass through the gut barrier into the hemolymph,where they can ***,we investigated the potential of a novel nanocarrier,drosophila X virus-like particle(DXV-VLP),for delivering a neurotoxin from the scorpion Androctonus australis Hector(AaIT)against the invasive pest fruit fly,drosophila *** results show that the fusion proteins of DXV polyproteins with AalT peptide at their Ctermini could be sufficiently produced in Lepidoptera Hi5 cells in a soluble form using the recombinant baculovirus expression system,and could self-assemble into VLPs with similar particle morphology and size to authentic DXV *** addition,the AalT peptides displayed on DXV-VLPs retained their toxicity,as demonstrated in injection bioassays that resulted in severe mortality(72%)in adults after 72 *** fed to adults,mild mortality was observed in the group treated with DXV-AalT(38%),while no mortality occurred in the group treated with AaIT peptide,thus indicating the significant role of DXV-VLPs in delivering AalT ***,this proof-of-concept study demonstrates for the first time that VLPs can be exploited to enhance oral delivery of insect-specific neurotoxic peptides in the context of pest ***,it provides insights for further improvements and potentially the development of neurotoxin-based bioinsecticides and/or transgenic crops for insect pest control.
