伪钝绥螨Amblyseius fallacis(Garman)原产于美国东部和中西部以及加拿大北部地区,是控制果园中二斑叶螨Tetranychus urticae(Koch)和苹果全爪螨Panonychus ulmi(Koch)的一种重要的捕食性天敌。早在50年代初该螨就引起人们的注意,开始从生物学、饲养、繁殖技术等方面加以研究。70年代初,Croft等人研究发现了该螨对谷硫磷、对硫磷等有机磷农药有很强的抗性,对在美国果园中普遍使用的氨基甲酸酯类有中等程度的抗性,而对有机氯 Amblyseius fallacis (Garman), native to the eastern, central and western parts of the United States and northern Canada, is an important control of Tetranychus urticae (Koch) and Panonychus ulmi (Koch) in apple orchards Predatory enemies. As early as the early 1950s, the mites caught the attention of people and began to study biology, breeding and breeding techniques. In the early 1970s, Croft and others found that the mite had strong resistance to organophosphorus pesticides such as azinphos-methyl and parathion, moderate degree of resistance to the commonly used carbamates in American orchards, And for organic chlorine
