摘　　要：介绍了油茶黑胶粉虱的分布、形态特征和发生规律及其病原微生物扁座壳孢的形态特征、发生情况和应用前景。在福建省清流县调查结果表明,扁座壳孢对油茶黑胶粉虱的林间自然感染率为32.8%～86.9%,自然控制作用较强。在油茶害虫的生物防治中,可利用自然带菌枝叶移挂法进行引种或通过人工培养制成菌剂来进行防治。Distribution, morphological character and occurrence regularity of Aleurotrachelus camelliae Kuwana as well as the morphological character, occurrence and application prospec of its natural enemy,Aschersonia placenta Berk. et Br. were introduced. The result of survey in Qingliu County of Fujian Province showed the natural infection rate of A. camelliae by A. placenta in the Camellia oleifera Abel forest was between 32. 8% -86.9%, which meant A. placenta could control A. cameUiae in the forest, so the natural boicontrol agent should be used in the biocontrol of the insect in the forest. The twig of Camellia oleifera with A. placenta could be introduced to the forest or A. placenta be cultured to fungi preparation for control.
