摘　　要：以福建漳州盆栽榕树种植示范基地为观测和试验点,调查分析害螨的为害症状、发生种类和优势种动态时间格局,测定7种药剂对害螨的田间防治效果。结果表明:盆栽榕树种植区的害螨种类有4个科6个属6种,优势种为桔全爪螨;优势种种群动态时间格局分为5类,依次经历发展期、第1高峰期、衰退期、第2高峰期和越冬期。7种药剂对害螨均有一定的防治效果,无药害,15%哒螨灵乳油和73%克螨特乳油对害螨具有较好的速效性,药后1 d防效超过73.00%;11%乙螨唑悬浮剂、24%螺虫乙酯悬浮剂、24%螺螨酯悬浮剂和73%克螨特乳油能持续控制害螨为害,药后30 d防效均在90.00%以上。The author took the export potted ficus planting-demonstration base of Zhangzhou as an observation point, indagated and analysed the pest mites＂ damaging symptom, species and the dynamic time pattern of the dominant species, tested the control efficiency of seven kinds of pesticides to pest mites. The result showed that the pest mites in potted ficus planting areas contained 6 species （4 families, 6 genera）, and the dominant species was Panonychus citri （McGregor）. The dynamic time pattern of the dominant species could be divided into five types： the development period, the first peak period, the decline period, the second peak period and the over- wintering period. Seven pesticides all had certain control efficiency and no phytotoxicity. 15% Pyridaben EC and 73% Propargite EC both had good quick-acting, with the control efficiency more than 73.00% one day after treatment. The control efficiency of 11% etoxazole SF, 24% spirotetramat SF, 24% spirodiclofen SF and 73% propargite ES could last and that after 30 days was more than 90.00%
