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 LC 15  and LC 30  of buprofezin significantly decreased the fecundity and longevity of both generations. Exposure of F 0  individuals to both concentrations delay the developmental period in F 1 . Furthermore, the survival rate, intrinsic rate of increase ( r ), finite rate of increase ( λ ), and net reproductive rate ( R  0 ) were reduced significantly in progeny generation at both concentrations. However, the reduction in gross reproductive rate ( GRR ) was observed only at LC 30 . Although, the mean generation time ( T ) prolonged substantially at LC 30 . Additionally, expression of the  CHS1  gene was significantly increased in F 0  adults. Significant increase in the relative abundance of  CHS1  mRNA transcript was also observed at the juvenile and adult stages of F 1  generation following exposure to LC 15  and LC 30 . Therefore, our results show that buprofezin could affect the biological traits by diminishing the chitin contents owing to the inhibition of chitin synthase activity in the succeeding generation of melon aphid.
