棉铃虫种群调查及测报技术

Investigation and forecasting techniques for the cotton bollworm

近年,棉铃虫Helicoverpa armigera(Hübner)在我国非棉花寄主作物上的发生危害呈明显加重趋势。本文依据棉铃虫生活习性和发生规律、棉花棉铃虫调查技术标准,概述了棉铃虫成虫、卵、幼虫、蛹等不同虫态的种群监测方法,介绍了小麦、玉米、花生等不同作物田种群系统调查和普查技术。同时,建议深入研究种植业结构调整下棉铃虫区域性发生规律、研发应用自动化和智能化种群监测方法、制定推广不同作物棉铃虫测报技术规范,旨在促进非棉花寄主作物上棉铃虫的有效监测、准确预报和科学防控及其种群区域性治理。

In recent years, the damage inflicted by the cotton bollworm, Helicoverpa armigera （Hiibner）, on non-cotton host crops has greatly increased in China. We here review monitoring methods for cotton bollworm adults, eggs, larvae and pupae, based on the habits and occurrence patterns of this pest and the technical standards for investigating it on cotton. We also introduce systematic and general survey methods for H. armigera on different host plants, such as wheat, maize, peanuts, etc. to allow more general population forecasting of this pest. In the future, we should strengthen the study of the occurrence patterns of the cotton bollworm, along with crop production structure adjustment, develop automatic and intelligent monitoring methods, and formulate and promote technical specifications for population forecasting in different crops. This will facilitate effective monitoring, accurate prediction, scientific prevention, and regional management, of cotton bollworm population in crops other than cotton.
