樟网圆蚧Pseudaonidia duplexCockerell1897,属盾蚧科Diaspidid-ae,圆蚧族Aspidiotini,网盾蚧属。为山东新记录。是分布广、寄主杂、危害严重的蚧虫。近十几年在山东越来越普遍,经调查在山东发现的寄主有:桂花、含笑、月季、蔷薇、文竹、茉莉、石榴、葡萄、佛手、山茶、紫荆、樟等。但以盆花受害最重。因其繁殖迅速,被害寄主的叶脉、枝条,甚至主干,很快布满虫体。引起寄主生长势衰退,常导致虫群上部枝条枯死,甚至整株死亡。从1983年以来,我们对盆花上樟网圆蚧的生物学特性及其防治进行了系统的研究,现将结果报导如下.
Zhang network scale Kuwana Pseudaonidia duplexCockerell1897, is a member of the scale Division Diaspidid-ae, Cordyceps family Aspidiotini, Network Shield Kuwana. Shandong new record. Is widely distributed, host hybrid, serious harm scale insects. Nearly a decade in Shandong more and more common, the survey found in Shandong host: osmanthus, smile, rose, rose, Wen bamboo, jasmine, pomegranate, grape, bergamot, camellia, Bauhinia, camphor and so on. But the worst flower potted. Because of its rapid breeding, victims of host veins, branches, and even the trunk, soon filled with parasites. Causing the host growth potential recession, often lead to upper branches of the swarm dead, or even whole plant died. Since 1983, we conducted a systematic study on the biological characteristics and prevention and control of Hemiptera: Campanulaceae, and the results are reported as follows.
