红蜡蚧Ceroplastes rubens Maskell是上海主要园林害虫之一,为害雪松、月桂等40多种观赏植物。成虫和若虫群集在嫩枝上,或少数在叶柄、叶片上吸取汁液。严重肘幼枝上满披此虫,诱发煤污病后,树势逐渐衰弱,降低或失去观赏价值。以往依赖化学防治,效果并不理想。为探索综合防治,我们从1978年起对红蜡蚧寄生性天敌进行了调查,现将结果整理如下。调查方法寄生蜂是直接从野外采集寄主,在室内作短期饲养后获得的。从上海8个绿化点采集寄生在雪松、香樟、构骨、榔榆、重杨木、乌柿、月桂等9种树木上的红蜡蚧,将其计数放入指形管内或不计数放入广口瓶和羽化箱内,管口和瓶口塞上和罩絷纱布,每天 Ceroplastes rubens Maskell is one of the major garden pests in Shanghai. It cures more than 40 ornamental plants such as cedar and laurel. Adult and nymphs cluster on shoots, or a few on petiole, leaf extract juice. Severe elbow young branches covered with this worm, induced coal pollution, the tree gradually weakened, reducing or losing ornamental value. In the past rely on chemical control, the effect is not satisfactory. In order to explore comprehensive prevention and control, we conducted a survey on the parasitic natural enemies of red wax scale from 1978, and the results are summarized as follows. Method of investigation Parasitic wasp was collected directly from the host in the field, after short-term rearing indoors. From eight greening spots in Shanghai, we collected red wax scales parasitized on nine kinds of trees, such as cedar, camphor, skeleton, beluga, poplar, persimmon, laurel, etc., counted them into finger tubes or did not count Into a wide jar and feather box, nozzle and bottle stopper and cover gauze gauze, every day
