麦长管蚜Macrosiphum avenae(Fabricius)是我国小麦生产上的重大害虫,给小麦生产造成严重的威胁。本研究采用人工模拟风雨气象因子的方法,研究了吹风和喷水对麦长管蚜种群数量的干扰作用,解析了麦长管蚜在种群不同发展阶段受模拟风雨干扰后种群变化的特征,明确了麦长管蚜受模拟风雨作用影响其种群生长的关键时期。结果表明,在小麦田进行模拟风雨试验,处理强度越大,防治效果越好;有目标的对靶喷施处理的防治效果明显高于非目标喷施处理;确定人工喷水或吹风处理的最佳时期为小麦灌浆初期,即在该阶段进行一次喷水处理,可以获得最佳的防治效果和保产作用。
Macrosiphum avenae (Fabricius) is a major pest in wheat production in our country, which poses a serious threat to the wheat production. In this study, artificial weather factors were used to study the effects of blowing and watering on the populations of aphids in Myzus persicae, and the characteristics of population changes after different periods of simulated wind and rain disturbance were analyzed. The wheat aphid affected by the simulated wind and rain the key period of its population growth. The results showed that the simulated wind and rain test carried out in the wheat field showed that the greater the treatment intensity was, the better the control effect was. The control effect of target spraying treatment was obviously higher than that of non-target spraying treatment. The best period for the early wheat filling, that is, at this stage for a water treatment, you can get the best control effect and yield protection.
