摘要
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。
Egg laying patterns of cotton bollworm in Huaibei cotton area were studied.Egg laying of cotton bollworm was an integrated action depend on the habits of the pest and environmental factors;the variance of oviposition quantity between different hosts,managemental modes,egg laying position,distance from light and taxis of cotton bollworm had no difference;the variance of oviposition quantity in different years and generations was influenced mainly by migration of cotton bollworm,climatic factors and crop distribution,but the oviposition period was more stable.
