摘要
黑刺粉虱 Ａｌｅｕｒｏｃａｎｔｈｕｓ 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。黑刺粉虱 Ａｌｅｕｒｏｃａｎｔｈｕｓ 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?
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.
