捕食螨是柑桔红蜘蛛的优势天敌。因为柑桔害虫种类较多,防治时往往使用各种化学农药,从而大量杀灭了天敌。在华南农业大学赵善欢教授主持下,我们开展了应用苦楝油(江苏宿迁县野生植物油料加工厂生产)防治柑桔红蜘蛛及对捕食螨的保护利用试验。现将1983—1984年我们进行的关于红蜘蛛与捕食螨田间消长关系的调查叙述如下。
Predatory mite is the dominant natural enemy of citrus red spider. Because citrus pests more types, prevention and control often use a variety of chemical pesticides, thus killing a large number of natural enemies. Under the auspices of Professor Zhao Shanhuan of South China Agricultural University, we conducted experiments on the prevention and control of citrus red spiders and the protection and utilization of predatory mites by applying neem oil (produced by the wild plant oil processing plant in Suqian County, Jiangsu Province). The following is a survey of the relationship between spider mites and predator mite in the fields we conducted in 1983-1984.
