对棉铃虫在淮北棉区的田间产卵规律进行了研究，结果表明：棉铃虫田间的产卵规律是该虫自身习性和环境因子综合作用的结果。寄主、栽培管理方式和光源距离不同，田间落卵量也随之变化。产卵部位及其分布同棉铃虫的趋性相一致。田间寄主的生育状况导致了棉铃虫产卵在寄主间分布的差异。年度和代次间落卵量的差异，主要受制于棉铃虫的扩散迁飞、气候因子和作物布局的变化。田间产卵的时间变化则表现出更为稳定的规律性 The results showed that the oviposition of cotton bollworm was the result of its own habits and environmental factors. Host, cultivation and management methods and light sources from different fields, the amount of eggs will also change. Spawning sites and their distribution consistent with the tropism of cotton bollworm. Reproductive status of field hosts led to differences in the distribution of H. armigera among the hosts. The difference in annual and inter-generational egg shedding is mainly due to the change of cotton bollworm’s dispersal and migration, climatic factors and crop layout. Changes in the time of spawning in the field showed a more stable regularity
