棉蚜(Aphis gossypii Glovex)是棉花苗期的重要害虫,发生量大,危害较重.为了减轻蚜害,自五十年代以来采用化学农药进行防治,取得了较好的效果.有的棉区自棉苗出土后,喷雾器不离手,轮番打药不停.由于连年大量使用化学农药,棉蚜产生了抗药性;提高用药浓度,增加化防次数,结果棉蚜不仅没有治下去,反而越治越多.从而影响了棉田生态平衡和环保效益.基于上述,我们从1978～1983年进行了系统研究,明确了棉花苗期棉田生态结构和昆虫的动态规律,开展以生态调控为基础、生物防治为主的棉蚜综合防治技术研究工作.
Cotton aphid (Aphis gossypii Glovex) is an important pest of cotton seedling, the occurrence of large, more damaging.In order to reduce the aphid damage, since the 1950s using chemical pesticides for prevention and treatment, and achieved good results. Since the cotton seedings unearthed, the sprayer does not leave the hands, turns fight drugs kept.As a result of successive years of heavy use of chemical pesticides, cotton aphid had resistance; improve drug concentration, increase the number of prevention and treatment, the results not only did not cure cotton aphid, but the more cure Thus affecting the cotton field ecological balance and environmental benefits.Based on the above, we conducted a systematic study from 1978 to 1983, clear cotton seedling cotton ecological structure and dynamics of insects, to carry out ecological regulation and control based on the biological control The main cotton aphid comprehensive control technology research.
