摘要：

Larvae picked up wettable powder particles on legs, setae, and mouth parts. Phosmet was 5 times more toxic in small droplets than in large droplets to first instar codling moth, but small droplets required 2.5 times the number/cm2. With large droplets, a larger treated area was required to produce 50% mortality. For any percentage area covered small droplets gave higher mortality. Speed of toxic action was related to amount of phosmet/cm2 and to no. of droplets/cm2. © 1979, Entomological Society of Canada. All rights reserved.
