AMPK (AMP-activated protein kinase) is a crucial cellular energy sensor across all eukaryotic species. Its multiple roles in maintaining energy homeostasis, regulating cellular metabolic processes have been widely investigated in mammals. In contrast, the function of AMPK in insects has been less reported.

Heavy metal is a serious environmental pollutant with all kinds of biotoxic effects. The immunomodulatory effects of Cd stress on Lymantria dispar larvae and its underlying mechanisms were investigated. The susceptibility of Cd-treated larvae to Beauveria bassiana (Bb) was significantly increased by 27.

Heavy metal pollutants are important abiotic environmental factors affecting pest habitats. In this study, Cd pre-exposure significantly increased the tolerance of Lymantria dispar larvae to β-cypermethrin, but did not significantly alter their tolerance to λ-cyhalothrin and bifenthrin. The activation of P450 by Cd exposure is the key mechanism that induces insecticide cross-tolerance in L.
