摘　　要：2004—2005年,对樟蚕江西亚种Eriogyna pyretorum cognata Jordan的形态特征、生物学特性、幼虫取食量进行了研究。结果表明:樟蚕江西亚种在云南省昌宁县1 a发生1代,以蛹在茧内在树上越冬。幼虫期取食鲜核桃叶。取食量最大为42.3 g,最小为39.4 g,平均41.5 g。吡虫啉、粮虫克粉剂喷粉,高效氯氰菊酯喷雾防治该虫,死亡率分别达到90.2%,91%和91.3%以上。The morphology, bionomics and larval ingestion of Eriogyna pyretorunz cognata were studied in 2004 and 2005. The results showed that Eriogyna pyretorum cognata had one generation a year in Changning County and overvcintered as pupa in the cocoon in the tree. The larva defoliated Juglans regia. The average ingestion was 41.5 g per larva with a maximum of 42.3 g and a minimum of 39.4 g. Dusting of Imidacloprid, LiangChongKe and spray of Cypermethrin could kill 90.2%, 91% and 91.3 % of the pest respectively.
