Clutch morphology and the timing of exposure impact the susceptibility of aquatic insect eggs to esfenvalerate.

abstract：:Field populations of aquatic organisms, particularly those inhabiting flowing waters, likely are exposed to short pulses of pesticides following periods of spray drift, surface runoff, or drain flow. In the present study, we investigated the effect of pulse exposures of a pyrethroid insecticide, esfenvalerate, on surv...
