摘　　要：通过对40%保桑灵EC田间防效和对家蚕安全间隔期试验,得出40%保桑灵EC对桑园鳞翅目害虫有较好的防治效果,尤其对桑尺蠖的防效较佳,宜在低龄盛期防治,推荐使用浓度1000倍,同时得出40%保桑灵EC对家蚕安全间隔期为15天。In this study, we investigated the field efficiency of 40% Bao Sang Ling EC and its safety interval for silworm. The results indieated that 40% Bao Sang Ling EC has a relatively good efficacy on Lepidopteran pest of mulberry, especially better for Phthonan- dria atrilineata Butler. It is recommended that 40% Bao Sang Ling EC should be used in the major onset of the young larvae, with 1000 times dilution. Furthermore, the safety interval of 40% Bao Sang Ling for silkworm should be 15 days.
