大蓑蛾的为害及防治方法研究

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。
