摘要
为探索刚竹毒蛾生物防治的方法，于2014年在福建省将乐县选用240亿屈白僵菌孢予粉、400亿／g绿僵菌孢子粉、160亿，g苏云金杆菌粉和1％苦参碱粉剂4种生物农药粉剂进行刚竹毒蛾2～3龄幼虫的林间防治试验。结果表明，用白僵菌、绿僵菌和苏云金杆菌防治后20d，虫口减退率达74％以上；用1％苦参碱防治后2d，45．0和30．0kg／hm。浓度下虫口减退率分别为77．1％和79．8％，20d后虫口减退率分别可达89．1％和91．1％。试验表明，上述4种生物农药均可有效防治刚竹毒蛾。
In order to explore the bio- logical control method of Pantana phil- lostacbysae, 4 kinds of biological pesti- cide powder, including 24 billion/g Beauveria bassiana spore powder, 40 billion/g Metarhizium anisopliae spore powder, 16 billion/g Bacillus thudngien- sis powder and 1% matrine powder were selected to control 2-3 instar larvae of P. phyllostachysae in 2014 in Jiangle County of Fujian Province. The results showed that the decline rate of P. phillostachysae was over 74% after 20 days using B. bassiana and M. Anisopliae and B. thuringiensis. By using 45.0 and 30.0 kg/hm2 of 1% matrine, the decline rate of P. phyllostachysae were 77.1% and 79.8% after 2 days, after 20 days the decline rate reached 89.1% and 91.1%, respectively. The experiments showed that 4 kinds of biological pesticide pow-der could be used to control P. phil- lostachysae.
