摘 要:笔者于1988~1991年在安吉县通过对竹虫发生类型区划、主要竹虫测报技术和在高虫口为害时推广以竹腔注射甲胺磷原液为主的化学防治并协调其他多种防治措施(包括营林技术、物理和化学防治),低虫口时注重虫情监测和营林措施等项竹虫综合防治技术研究,取得很好防治效果,达到了有虫不成灾,竹林虫口基数和防治费用逐年下降,防治费用与收益比为1:9.6,深受竹农欢迎。This paper dealt with the division of occurrence type,fore- casting techniques of the main bamboo insects and its chemical control by bamboo cavity injection with Tamaron at high insect density in concert with other various control measures including silvicultural,physical and chemical control at Anji county,Zhe- jiang province during 1988~1991.The good control results were occurred and damages caused by bamboo insects were below eco- nomic threshold.The control cost was reduced and the ratio of control cost to benefit return was 1:9.6.
