园林植物蚧虫及其天敌调查

Survey on scale insects and natural enemies of landscape plants

调查结果表明为害园林植物的蚧虫隶属4科19属35种。发生普遍而严重的是咖啡盔蚧、龟蜡蚧、酱褐圆蚧、考氏白盾蚧、米兰白轮盾蚧和云南白轮盾蚧等。寄生性天敌以膜翅目蚜小蜂和跳小蜂为主;捕食性天敌主要有瓢虫、日本方头甲等。利用天敌昆虫防治园林植物蚧虫具有十分重要的意义。

Based on the experiments and investigations conducted both in the field and laboratories, 35 species were collected which belonged to 19 genera, 4 families. The serious and common pests included Saissetia coffeae, Ceroplstes floridensis, Chrysomphalus bifasciculatus, Pseudaulacaspis cockerelli, Aulacaspis crawii and Aulacaspis ferrisi. Aphelinidae and Encyrtidae were two crucial Parasitoids while Coccinellidae and Cybocephalus nipponicus were main predators for scale insects. It is of great significance to take advantages of natural enemies to control scale insects.
