喜树幽斑螟是喜树的一种新害虫。该虫的综合防治应以生物防治为基础。试验表明,复合生物杀虫剂对幼虫有良好防治效果,低龄幼虫盛发期可喷洒Bt-8010 1-2×109孢子·ml-1+白僵菌1-2×108孢子·ml-1+80%DDVP1/20000;冬季树干涂白也有良好防治效果。
Camptotheca ricketularis is a new pest of the camptothecin. The integrated pest control should be based on biological control. The results showed that the composite biopesticide had good control effect on larvae, and the young larvae could spray 1-2 × 109 spores · ml-1 + 1-2 × 108 spores · ml-1 + 80% DDVP1 / 20000; winter trunk white coating also has good control effect.
