棉铃虫分本很广，在世界各棉区均有分布，在我国各棉区普遍发生。新疆在60年代到80年代中期，棉铃虫也曾造成过严重为害，80年代中期到90丰代初期，棉铃虫发生很轻。从1994年起，棉铃虫在新疆棉区开始回升，1996年棉铃虫在吐鲁番、喀什棉区大发生．棉铃虫在新疆棉区大发生为害的特点是：发生范围广，为害面积大，虫口数量大，发生早且为害时间长，越冬蛹数量大。棉铃虫数量上升的原因是：嗜好食物的增加，为棉铃虫发生提供充足的营养条件；秋耕冬灌面积小，棉铃虫越冬基数大；防治措施不到位。棉铃虫的防治应当贯彻“预防为主，综合防治”的植保方针。在防治措施上应强化农业防治措施，做好诱蛾工作，消灭棉铃虫于棉田外，保护利用天敌，严格防治指标，科学施用农药。
The bollworm has a very wide distribution, which is distributed in every cotton area in the world and occurs in every cotton area in our country. In the period from the 1960s to the mid 1980s, the cotton bollworm also caused serious damage. From the mid-1980s to the early 1990s, the bollworm occurred very lightly. Since 1994, the cotton bollworm began to rebound in the cotton area of Xinjiang. In 1996, cotton bollworm occurred in Turpan and Kashi areas. The occurrence of cotton bollworm in the cotton area in Xinjiang is characterized by a wide range of occurrence, large area of damage, large number of insect population, early occurrence and damage for a long time, and large numbers of overwintering pupae. The reason for the increase in the number of bollworm is: increase of food addicted to provide sufficient nutrition conditions for occurrence of cotton bollworm; autumn plowing winter irrigation area is small, bollworm overwinter base number; prevention and control measures are not in place. The prevention and treatment of cotton bollworm should implement the policy of plant protection of “prevention first, comprehensive prevention and control”. In the prevention and control measures should strengthen agricultural control measures, do a good job of moths, eliminate cotton bollworm in cotton fields, the protection and use of natural enemies, strict control indicators, the scientific application of pesticides.
