Imidacloprid resistance in the brown planthopper(BPH),Nilaparvata lugens is primarily the result of the overexpression of cytochrome P450 monooxygenases.
As one of the most crucial components in the cuticle,cuticular lining of the foregut,hindgut,trachea,and peritrophic membrane in insects,chitin is widely distributed in fungi,nematodes and other arthr
Transcription factor BmPOUM2,with the assistance of transcription factor BmAbd-A,binds to the cis-response elements(CREs)of the wing disc cuticle protein gene BmWCP4 and mediates the 20E-induced expre
20-hydroxyecdysone(20E)as a main regulator of metamorphosis,development,and reproduction,also regulates the innate immune response in many holometabolous insects.
The steroid hormone 20-hydroxyecdysone(20E)and the serine/threonine Ste20-like kinase Hippo signal promote programmed cell death(PCD)during development,although the interaction between them remains un
Insects solve the ecophysiological problem of restricting water loss to prevent dessication by depositing long-chain hydrocarbons as essential waterproofing components on their epicuticle.
