摘要
通过为期2 a的观察,掌握了美国白蛾在苏北的生活史、发生及危害特性,发现成虫产卵、幼虫取食对不同树种有选择性,老熟幼虫化蛹场所有选择性,幼虫分散高峰为药物防治适期。
In this paper,we got the life history,the occurrence and the hazard trait of Hyphantria cunea in northern Jiangsu by two years＇ observation.We found that the adult spawning and the larva feeding got obvious selectivity to different tree species.And the old larva also got selectivity to the pupation place.The suitable control to Hyphantria cunea is at the peak period of the dispersion.
