| 摘 要： | 田问药效试验结果表明，1％甲维盐EC2000倍、25g／L菜喜SCl000倍、16000IU／mg苏云金杆茵WP200倍、0．3％苦参碱ASl000倍、森得保WPl000倍对大叶黄杨斑蛾3～4龄幼虫均有良好的防治效果，药后3d均停止取食，保叶效果优良，校正虫口减退率分别为96．4％、94．1％、76．0％、100．0％、87．4％；药后7d校正虫口减退率均达100．0％。5种生物农药可在园林绿地中推广应用，其中以甲维盐和森得保使用成本低，值得大面积推广使用。

| Abstract: | Field evaluation results indicated： 1% emamectin benzoate EC2000~, 25 g/L success SC1000 times, 16000 IU/mg Bacillus thuringiensis WP200 times, 0.3% matrine AS1000 times, sendebon WP1000 times have good control effects to 3~4 instar larvaes ofPrgeria sinica Moore. 3 days after treatment, all larvaes stopped feeding. Respectively corrected population decline rate of these treatments was 96.4%, 94.1%, 76.0%, 100.0% and 87.4%. All biopesticides have 100% corrected population decline rate after 7 days treatment. The results showed all of these 5 biopesticides can be applied in landscape green spaces. The emamectin benzoate and sendebon were worth wide use in the large area because of low cost. |
