Abstract

Abstract In the present study, the effects of sublethal concentrations of buprofezin on life-table traits ofS. furcifera were evaluated for two consecutive generations (F0 and F1). Our results exhibited that the fecundity, life span (longevity) and hatchability of the F0 and F1 generations were significantly decreased at LC30 compared to the control. However, copulation was not significantly affected for the F0 or F1 generations at sublethal concentrations. The female life span was affected negatively at both treatments in F0 and at LC30 in F1, compared to the control. Furthermore, significant effects of the sublethal concentrations were found on the developmental rate of all instars except the 3rd instar of F1. However, the pre-adult period, total pre-oviposition period (TPOP) and adult pre-oviposition period (APOP) significantly increased in F1 individuals at LC30 and LC10 compared to the control. Our findings revealed that demographic characters (survival rate, intrinsic rate of increase (ri ), finite rate of increase (λ), net reproductive rate (R 0 ), and gross reproductive rate (GRR )) of the F1 generation (from F0 parents) significantly decreased compared to the untreated group; however, the generation time (T ) increased at LC10 . Therefore, the results suggested that buprofezin could adversely affect individuals in the successive generation.
