Abstract Allium mongolicum Regel leaf beetle, Galeruca daurica (Coleoptera: Chrysomelidae) is rampantly harmful in Inner Mongolia grassland. However, the current management strategies for this pest still heavily rely on chemical control using traditional insecticides or those with novel action. In study, we conducted an indoor bioassay to evaluate sublethal effects of chlorantraniliprole biological characteristics. Additionally, assessed activity detoxification enzymes, specifically primary enzymes carboxylesterase (CarE) and cytochrome P450, insect's secondary metabolic namely glutathione S‐transferase (GST) uridine diphosphate glycosyltransferase (UGT), as well its gene expression profile. The developmental period 3rd instar larvae G. was significantly prolonged after treatment chlorantraniliprole, which negatively affected hatching, pupation diapause rates their body weight. showed different dynamics enzyme activities within 24 h treatment. Different concentrations inducing effect activities, while no significant difference observed P450. Expression profiling detoxifying genes screened by transcriptome data has revealed that 6 CarE, 2 GST, 7 UGT 31 P450 were up‐regulated. conclusion, chlorantraniliprole's resulted a deceleration growth processes increased levels GST UGT. proteins encoded up‐regulation may involve metabolism chlorantraniliprole.

A representative silkworm rearing mode of Ⅰ-Ⅲ instars reared on artificial diet and Ⅳ-Ⅴ fresh mulberry leaves has been recognized in some sericultural areas China. Under this mode, silkworms are prone to be poisoned by pesticide residues at the Ⅳ Ⅴ instar stages. As one most widely applied insecticides, λ-cyhalothrin was used study insecticide tolerance (referred as AD group). Our results showed that newly ecdysized larvae group were less tolerant compared ML After continuous exposure trace λ-cyhalothrin, weight gain survival rate significantly lower than those group, even though compensatory growth observed control group.
