小麦蚜虫在我国小麦产区分布广、发生量大、为害严重;同时又是小麦病毒病的传毒媒介,往往是蚜害重,病毒病就重,致使小麦严重减产。过去,防治麦蚜多用乐果、对硫磷和甲胺磷等农药,这些农药有的药效已有所下降,有的毒性很高,易造成人畜中毒。因此近两年来,有改用拟除虫菊酯类农药防治麦蚜的趋势,但这些农药量少价高,有的品种还靠进口,不能满足广大农村的需要。为此,我们于1983—1985年进行了防治麦蚜的药剂筛选,在供试的19种农药中,杀螟松药效显著。杀螟松又叫杀螟硫磷、速灭松、
Wheat aphid widely distributed in China’s wheat producing areas, the occurrence of large, serious damage; the same time is the vector of wheat virus transmission medium, often aphid heavy weight, heavy virus disease, resulting in serious wheat yield. In the past, the prevention and control of wheat aphids and more with dimethoate, parathion and methamidophos and other pesticides, some of these pesticides have some efficacy has decreased, and some highly toxic, easy to cause human and animal poisoning. Therefore, the past two years, the use of pyrethroid pesticides to prevent wheat aphid trend, but these pesticides at low prices, and some species also rely on imports, can not meet the needs of the vast rural areas. To this end, we carried out in 1983-1985 to control wheat aphides drug screening, test 19 pesticides, fenitrothion significant effect. Diafenide also called fenitrothion, speed off pine,
