Abstract: In 1984-1985, several tree-borer-killing insecticides were tested for their toxicity to Anoplophora glabripennis (Motschulsky), which causes serious damage to the willow trees in the scenic sites of the West Lake, Hangzhou. The experiments showed that spraying of the trunks and twigs with 20% "8302" and 10% "8310" emulsions (diluted to a concentration of 0.25% with water) usually resulted in 95% mortality. It was clear that these two insecticides were much more effective in killing the borer than the other insecticides tested, and their effects were not affected by the diameter of the trunks and twigs.
