摘　　要：在福安进行了4种不同类型农药使用效果综合评价茶园小区试验,0.5%藜芦碱粉剂800倍液防治茶小绿叶蝉、茶蚜、茶丽纹象甲效果良好,对茶园蜘蛛有一定的杀伤力,但药后15 d可正常恢复,对茶园节肢动物群落结构总体上有积极作用;70%吡虫啉水分散粒剂15000倍液防治茶小绿叶蝉、茶蚜效果良好,对茶园蜘蛛安全,对茶园节肢动物群落结构的影响相对较轻;99%矿物油50倍液防治茶小绿叶蝉、螨类的效果较好,对茶园蜘蛛有一定的杀伤力,但药后15 d可正常恢复,对生态系统结构有负面影响趋势;2.5%联苯菊酯乳油1000倍液防治茶蚜、螨类效果较佳,对茶园蜘蛛有较强的杀伤力,对生态系统结构有负面影响趋势。A field trial was conducted to make a comprehensive evaluation via the controlling effects of four pesticides on pests and arthropod community. 800 times diluent of 0.5% vertrine WP exhibited the good effects on controlling Empoasca vitis Gothe, Toxoptera aurantii Boyer de FonscoLombe, and Myllocerinus aurolineatus Voss, but it had an adverse effect on spider population in a short time （15 d after spray）, which in general reflected the positive effects on arthropod community composition. 15000 times diluent of 70%imidacloprid WDG had good effects on controlling Empoasca vitis G？the, Toxoptera aurantii Boyer, furthermore, it was safe for spider and had a lower influence on arthropod community composition. 50 times diluent of 99%petroleum oil had good effects on controlling Empoasca vitis Gothe and mites, also the same effect on spider population as vertrine WP, and nagative effects on arthropod community composition emerged. 1000 times diluent of 0.5%bifenthrin EC showed the better effects on controlling Toxoptera aurantii Boyer de FonscoLombe and mites, however, it expresssed the strong lethality to spiders and brought about the nagative effects on arthropod community composition.
