摘　　要：记述橄榄星室木虱PseudophacopteroncanariumYangetLi的外部形态、生活习性、天敌种类和药剂防治试验。此虫在福州一年发生7～9代，第一代成虫始见于4月下旬，世代重叠明显，一年中的7月上旬至9月上旬先后出现三个成虫高峰，而以9月上旬的成虫数量最多。药剂防治试验表明，20％灭扫利防效最好，喷药后第2d药效达96．5％；其次是10％溴氟菊酯，喷药后第2d药效达到93．8％；此外，2．5％敌杀死、40％氧化乐果与80％敌敌畏等药效也在81％～90％。天敌种类繁多，诸如瓢虫、草岭、郭公虫、蜘蛛与捕食螨等。尤以瓢虫的种类和数量都相当多，在抑制橄榄星室木虱的种群消长中起了重要的作用。研究工作还包括首次引用绿僵菌属（Metarhizium）于橄榄星室木虱之防治，开辟了该虫防治的新途径。The morphological character, biology, and natural enemies of Pseudophacopteron caharium were studied. In the meantime, chemical control was carried out against the pest. It has 7~9 overlapping generations in a year, the first generation adults appeared in late April, and there are three adult peaks during early July to early September. In addition, experiments showed that the best chemical to control this pest was Meothrin, it could result in 96. 5 % control effect in the next day after spraying, the second was Fenvalerata,93. 8% the next day, and the rest-2. 5 % Decis, 40% Omethoate and 80% Dichlorvos was all between 81 % ~ 90%. Many kinds of natural enemies played important roles in suppression of the population development of the pest. There were beetles, chrysopas, cheroidea,spiders and predatory mites, of which beetles were dominant. The entomogenous fungus Metarhizium was also first introduced to control this pest.
