摘要
本文报道了湖南省枣铁倍蚜Kaburagia ensigallis和蛋铁倍蚜K.ovogallis的两种新冬寄主藓:东亚毛灰藓Homomallium connexum和东亚褶叶藓Palamocladium macrostegium。自然倍林中调查和基地实验结果表明,这两种藓是枣铁倍蚜和蛋铁倍蚜的优良冬寄主。此外,对两种新冬寄主藓的生物学特性、繁殖栽培方法和培育管理等也作了探讨。
The hard ensiform gall and hard egg-shaped gall are formed by hard ensiform gall aphid, Kaburagia rhusicola, and hard egg-shaped gall aphid, K.ovogallis respectively on the leaves of Punjab Sumac, Rhus punjab-ensis var. sinica. In order to get a high yeild of both gallnuts, a sufficient amount of overwintering hosts, some species of mosses, should be planted in the galinut woodland. In this paper, 2 new overwintering hosts, Hom-omallium connexum (Card.) Broth. (Hypnaceae) and Palamocladium macrostegium (Sull.et lesq.) Iwats. et Tak., (Brachytheciaceae) for both aphids are reported. Both of the mosses are ectohydric and epiphytic mosses on the rock or on the trunk, belonging to drought-enduring mosses. The population density of the aphids, which are parasitic on the mosses, shows that the H. connexum and P. macrostegium are both excellent overwintering hosts for the aphids. The Biological characteristics, cultivation techniques and field management for transplanting these 2 new overwintering hosts are also discussed in this paper.
