六十年代以来,柑桔红蜘蛛[Panonychus citri(McG)]严重威胁柑桔生产,且对多种农药产生抗性,化学防治有困难,防治费用较高。为寻求经济、安全、高效的防治途径,我们从1974年开始本项研究。根据1975、1976年在广东沙田调查,柑桔红蜘蛛的自然天敌有钝绥螨、食螨瓢虫、草蛉、塔六点蓟马、蜘蛛等,其中钝绥螨占70％以上。
Since the 1960s, Panonychus citri (McG) has seriously threatened the production of citrus and has resistance to many kinds of pesticides. It is difficult to control chemicals and has a high cost of prevention and treatment. In order to seek an economical, safe and efficient way of prevention and treatment, we started this study in 1974. According to the survey conducted in Shatian, Guangdong in 1975 and 1976, the natural enemies of citrus spider mites include Amblyseius mites, ladybugs, ladybugs, six-point thrips and spiders, among which Amblyseius accounts for more than 70%.
