柑桔红、黄蜘蛛是柑桔主要害虫之一。由于生产上多采用化学防治,致使其抗药性增强,用药量增加,生产成本提高,而防治效果越来越差,对环境的污染也日趋严重。1982—1983年我场在学习外地经验的基础上,积极保护利用场内果园中的天敌钝绥螨,采用生防与化防相结合的办法控制红黄蜘蛛,取得一定成效。现将两年试验结果,简要总结于后。
Citrus red, yellow spider is one of the major citrus pests. Due to the fact that more chemical prevention and control are used in production, the drug resistance is increased, the dosage is increased, the production cost is increased, and the prevention and control effect is getting worse and worse, and the pollution to the environment is also aggravating day by day. From 1982 to 1983, on the basis of learning foreign experiences, my field actively protected and utilized aureus mites, a natural enemies in the field orchard, and controlled the red-and-yellow spiders by combining biological control with chemical prevention and treatment. Now two years test results, briefly summarized later.
