摘　　要：建立了黑刺粉虱的发生期预测式和发生量预测式，在闽东北地区验证，其准确率达９０％以上；确立了动态防治经济阈值，一般为每叶６头。韦伯虫座孢菌对黑刺粉虱幼虫的致病力强，并能寄生蛹，田间大面积应用防治效果在７０％以上，持效达２年以上。卵孵化１０％—２０％时使用２５％扑虱灵，防效达８０％—９０％。研究表明：利用虫生真菌、昆虫生长调节剂和叶面肥（混用），能有效地控制黑刺粉虱的危害，经济效益。The forecasting model on the occurring date and the population density of citrus black spiny whitefly was established.The accuracy was over 90% in Northeast of Fujian Province.The economic threshold was established in the 6 larvae per leaf.The Aegerita webberi Fawcett entomogenous fungus was recommended as the main biological agent.It was showed high parasitizing percentage to larvae.It also parasitized pupae.The control efficacy was more than 70% in large scale tea gardans and persisted more than 2 years.The application of Buprofezin(Applaud)25% during the hatching percentage of whitefly egg in the range of 10%—20%,a control efficacy of 80%—90% can be reached.An integrated management programme including the combination of entomogenous fungi,insect growth regulator(IGR)and foliar fertilizer was put forward by the authors and resulted in good economic,social and ecologic efficiencies.
