| 摘 要： | 采用人工释放赤眼蜂和瓢虫对烟地主要害虫进行生物防治,对生物与化学药剂田间防治效果进行调查、记载并对防治效果进行了比较。结果,生物防治与化学药剂田间防治效果相当,但有利于生态环境的保护和生产无公害农产品,值得大面积推广使用。

| Abstract: | The main insect pests(Heliothis assulta,Prodenia litura and Myzus persicae) in tobacco field were biologically controlled by releasing natural enemies(Trichogramma and ladybird beetle) compared with that by chemical agents.The results show that there is no difference between the biological control and chemical agents methods in controlling insect pests,but the biological control method is benefit for protection of ecological environment and production of the agricultural products with pollution-free.Therefore,the biological control method should be popularized in tobacco production. |
