摘要
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。
The English grain aphid Macrosiphum avenae（Fabricius） is one of the most prominent agricultural pests of wheat and causes economically significant damage to wheat crops in China.We artificially simulated wind and rain to investigate the effect of these weather conditions on the population development of M.avenae.Population development and recovery were slowed by simulated wind and rain at different stages of population development.Furthermore,the critical period of M.avenae population development was the most affected.The greater the treatment intensity the stronger the effect.The control effects of target spraying were obviously higher than those of non-target spraying.We found that the early filling stage of wheat was the most suitable period for the application of artificial rain or wind.
