High-Voltage Electrostatic Fields Adversely Affect the Performance of Diamondback Moths over Five Consecutive Generations

Changing electrical environments can influence the performance of herbivorous insects and adversely affect their control strategies. The diamondback moth, Plutella xylostella (L.), is a pest that devastates cruciferous vegetables. An age–stage, two-sex life table P. over multiple generations was established to describe effect varying high-voltage electrostatic field (HVEF) exposure on after age-cohort eggs were exposed HVEF at an intensity 5.0 kV/cm for different durations. results show direct affected population dynamics parameters generations. In particular, net reproduction rate, intrinsic natural increase finite rate significantly decreased in third fifth under 10 min, while mean generation time doubling increased. Similarly, min rapidly reduced survival adult first generation, subsequently, it declined evenly slowly. Meanwhile, fecundity revealed had strongest inhibition five consecutive addition, increased superoxide dismutase activity produce extra hydrogen peroxide; however, catalase peroxidase or triggered accumulation malondialdehyde instar xylostella, especially treatment. present findings provide experimental evidence theoretical basis developing strategies new environments.
