黑刺粉虱及其天敌的研究

黑刺粉虱Aleurucamhus spiniferus Quaint．是柑桔、茶树等经济作物的重要害虫。福建一年发生4-5代，闽北、闽中发生4代，世代重叠。主要以若虫在柑桔等叶背越冬，越冬若虫于翌年2月间开始化蛹(伪蛹)，4月间成虫羽化并产卵。各世代若虫发生期为第一代4月上旬至6月上旬；第二代6月中旬至7月下旬；第三代7月中旬至9月上旬；第四代9月中旬至翌年3月，11月进入越冬期。一年中以6-9月为发生为害高峰期。黑刺粉虱的寄生性天敌和捕食性天敌资源丰富，蛹期被寄生率甚高，对该虫的综合治理可以生物防治为主要措施。

Studies on Aleurocanthus spiniferus Quaint. and it's natural enemies

Aleurocanthus spiniferus Quaint., an important pest of the economic crops such as citrus and tea, developes 4-5 generations per year with generation overlapping in Fujian Province of China. It overwinters with the nymphs under the surface of leaves. The overwintering nymphs begin to pupate in February next year, and the adult is emergent and oviposits during April. The development period of nymphs each generation is from early April to early June with the 1st generation, from mid June to late July with the 2nd, from mid July to early September with the 3rd, and from mid September to next March with the 4th, respectively. The pest overwinters after November and peaks from June to September. The natural enemies of Aleurocanthus spiniferus Quaint. and the biological control as a major measure are also dealt with in the paper.
