【摘要】 竹篦舟蛾在闽西北部分县(市)危害毛竹林,幼虫不但取食竹叶,同时还咬断叶基造成落叶,严重影响竹林生长,降低笋竹产量;严重发生时可将叶片吃光,甚至造成立竹枯死。用1.2%苦参碱.烟碱乳油与白石粉配制成含药量4%的杀虫粉剂,防治第一代2~4龄幼虫,见效快、施药方便,解决了丘陵山地不便采用水剂、烟雾剂方式防治的难题。施药后20 h内害虫被击落致死达91.7%;施药50 h后,24 h内掉落地面的毛竹叶片数量减少了88%。

【Abstract】 Besaia goddrica caused harm to Moso Bamboo forest in some counties of northwest Fujian Province.The larvae not only eaten off bamboo leaves,but also caused leaves falling by snapping leaf base.This seriously impeded the growth of bamboo,reducing output of bamboo forest.Sometimes even eaten up all the bamboo leaves on the shoots so that those standing shoots died down.Using 4% dose insecticidal dust making up with 1.2% Matrine·nicotine EC and white limestone powder,the first generation larvae of 2~4 instars had been quickly and conveniently prevented and controlled,solving the problem of inconvenience to apply water or aerosol insecticides in the hills and mountains.The application had caused 91.7% pests died of after 20 hours.After 50 hours application,the bamboo leaves falling to the ground reduced 88%.
