麦长管蚜种群动态与防治技术研究

TUDY ON THE POPULATION DYNAMICS AND INTEGRATED CONTROL OF SITOBION AVENAE(F.)

本文探讨了小麦不同生育期麦长管蚜的为害损失、防治指标及天敌控蚜作用,提出了保护利用天敌、合理用药、协调化学防治与生物防治矛盾的防治策略。

In this paper,a series of investigations on population dynamics ofSitobion avenae (F.) and its natural enemies,damage and action thresh-olds of this aphid in different developmental stage of wheat,controleffect of natural enemies,optimum insecticides,spraying time,anddosage,were reported.An integrated control tactics in wheat field,in-cluding protection and use of natural enemies,and rational applicationof insecticides was proposed to coordinate the actions of chemical con-trol and biological control.
