Impact of low lethal concentrations of buprofezin on biological traits and expression profile of chitin synthase 1 gene (CHS1) in melon aphid, Aphis gossypii.

ABSTRACT: Buprofezin, a chitin synthesis inhibitor that can be used for the control of hemipteran pests, especially melon aphid, Aphis gossypii. The impact of low lethal concentrations of buprofezin on the biological parameters and expression profile of CHS1 gene were estimated for two successive generations of A. gossypii. The present result shows that the LC₁₅ and LC₃₀ of buprofezin significantly decreased the fecundity and longevity of both generations. Exposure of F₀ individuals to both concentrations delay the developmental period in F₁. Furthermore, the survival rate, intrinsic rate of increase (r), finite rate of increase (λ), and net reproductive rate (R₀) were reduced significantly in progeny generation at both concentrations. However,
