粘虫(Leucania separata WalKer)和麦长管蚜[Macrosiphum granarium(Kirby)]是我省小麦生产上的主要害虫,大量发生与严重为害均在6月中、下旬,正值小麦抽穗,扬花、灌浆阶段,受害后影响产量十分严重。该时又正是大秋作物铲趟忙季,在大发生年往往由于人力和药剂、药械的不足,延误防虫的有利时机。根据生产上存在的问题,我们于1976年在本院试验站对粘虫和麦蚜进行大面积防治的同时,开展了以下几项防治试验,作为今后防治措施的参考。
Leucania separata WalKer and Macrosiphum granarium (Kirby) are the major pests in wheat production in our province. Both heavy and serious damage occurred in mid-to-late June. Stage, after the victim affected the yield is very serious. At this time, it was the big autumn crop shoveling the busy season. In the big occurrence years, the favorable opportunity of pest control was delayed due to the shortage of manpower, medicine and medicine. According to the problems in production, we carried out the following prevention and cure tests in large-scale prevention and control of armyworm and wheat aphid at our laboratory in 1976 as a reference for future prevention and treatment measures.
