Mechanism of Low‐Concentration Chlorantraniliprole Exposure Defects and Molting in <i>Bombyx mori</i> Larvae Based on <scp> Ca ²⁺ </scp> Homeostasis

-regulating genes, consequently suppressing both transcription and protein expression of the molting target gene Ftz-f1, which ultimately leads to molting defects in silkworms. The present study reveals the molecular mechanism of the impaired molting of fourth-instar molting defects caused by low-concentration CAP exposure, which provides critical evidence for the safety evaluation of low-concentration CAP residues and the sublethal toxicity to the lepidopteran insect.
