摘　　要：[目的]研究大蓑蛾的为害症状及与其他种类间的识别,并探讨对其有效的防治方法。[方法]调查大蓑蛾在田间的为害症状并与其他常见蓑蛾进行比较;分析大蓑蛾不同防治方法的特点,并总结几类常见蓑蛾的防治措施。[结果]大蓑蛾寄主广泛,主要以幼虫为害;白囊蓑蛾与茶褐蓑蛾幼虫在护囊中咬食叶片、嫩梢或剥食枝干、果实皮层,造成局部茶丛光秃。喜集中为害;茶小蓑蛾幼虫咀食叶片,使之斑驳破烂。大蓑蛾的防治应以农业防治为基础,物理防治、生物防治相结合,化学防治为辅;白囊蓑蛾与茶褐蓑蛾在发现虫囊时应及时摘除,集中烧毁。注意保护寄生蜂等天敌昆虫。另外可以施用化学药剂;茶小蓑蛾防治适期掌握在1、2龄幼虫期。[结论]该研究可为蓑蛾类昆虫的研究及防治提供依据。[Objective]The research aimed to study on the damage and control method of Clania variegata Snellen.[Method]The damage symptoms of C.variegata Snellen in field were investigated and were compared with other common Clania insects.The characteristics of control way on C.variegata Snellen were analyzed and the control methods of other Clania insects were summarized.[Result]C.variegata Snellen had extensive hosts,and it mainly was larvae who damaged.Larvae of Chalioides kondonis Matsumura and Mahasena colona Soaan bit leaves,shoots,or peeled branches,cortex of fruits,resulted in the baldness of part tea bush.And they loved to damage intensively.Acanthopsyche sp.larvae bit leaves and led to mottled leaves.the prevention of C.variegata Snellen should take agriculture prevention as basis,combined with physics prevention and biology prevention,chemistry prevention as assistance;the worm bags of C.kondonis Matsumura and M.colona Soaan should be removed and burned up when found.The natural enemy insects such as parasitoid should be protected.And chemical agents could be used to control them;the suitable control time of Acanthopsyche sp.should be larva phase at 1 or 2 age.[Conclusion]This study could provide references for the research and control of Clania insects.
