棉铃虫抗药性现状及治理对策

棉铃虫抗药性已成为当今我国棉虫防治中的突出难题,对棉花生产的持续、稳定发展威胁极大。本文较全面地综述了我国棉铃虫抗药性的发生与现状及其测定与监测;在分析抗药性起因机制的基础上,从南、北棉区农业生态系统的基本特点出发,提出了生物生态技术“压两头”、科学用药技术“控中间”的抗药性棉铃虫治理对策。

Status and Management of Insecticide Resistance of Cotton Bollworm Heliothis armigera

Insecticide resistance of the cotton bollworm, Heliothis armigera, has become the most troubleseme problem in controlling cotton insect pests in China, posing great threat to stable development of its cotton production. In this paper, incidence, status, measuring and monitoring of insecticide resistance of the bollworm are reviewed. Based on analyses of the causes and mechanisms of resistance, a new strategy of insecticide resistance management for the bollworm is proposed, namely suppression of the bollworm at the early and late seasons through coordinated application of bio-ecological-regulating techniques and control of the pest at the mid season through rational application of insecticides.
