| 摘 要： | 通过调查、观测,了解了落叶松毛虫的生物生态学特性及在勃利县的分布状况及特征,对该害虫进行了预测预报研究,得出食叶量与发生量之间的关系公式y=21893x-43.213（R^2=0.9999）,使用绿色微雷进行树干涂环法进行了防治,防治成本低,效果达98%以上。 |
| 关 键 词： | 落叶松毛虫 预测预报 防治 |

| Abstract: | Through investigations and observations,bio-ecological characteristics of Dendrolimus superans,conditon distribution & characteristics in Boli county were known;this pest was conducted predicting and forecasting study.Result shows that: the relation formula between leaf consumption & occurrence amount is y = 21 893x-43.213(R2 = 0.999 9);with insecticidal ring on trunk by cypermethrin to control,control cost is low and the effect reaches above 98%. |
| Keywords: | Dendrolimus superans prediction control |
