摘  要:
为筛选岫岩地区防治美国白蛾的最佳药剂,以3龄美国白蛾幼虫为研究对象,对不同浓度梯度的3种不同类型的无公害生物源药剂的防效进行了室内筛选和林间验证试验。结果表明,3种药剂均有良好的防治效果,比较而言,微生物源药剂苏云金杆菌400倍液速效性较好,但持效性较差;动物源药剂灭幼脲3号2 500倍液迟效性显著,防治效果最差;而植物源药剂苦参碱1 000倍液在速效性和持效性上综合表现最佳。

摘  要:
In order to screen the optimal pharmacy to control Hyphantria cunea in Xiuyan Area,taking 3-year-old larvae of Hyphantria cuneaas the research object,control effect of three pollution-free biological source pharmacy at different concentration gradient were screened.Result shows that three kinds of agents all have good control effect,in comparison,the microbial source medicament--400-times-liquid bacillus thuringiensis is available,but the effect is poorer.Slow acting of 2 500 times Chlorbenzuron No.3(animal-origin agents)is significant,and the control effect is the lowest;in terms of availability and effectiveness,comprehensive performance of 1 000 times matrine(plant-source-medicament)is optimal.
