海南发现椰子织蛾的重要天敌褐带卷蛾茧蜂

Bracon adoxophyesi,an important natural enemy of Opisina arenosella,found in Hainan Province

椰子织蛾是棕榈植物的重要入侵害虫,在印度和斯里兰卡严重危害椰子树。2013年在海南省万宁市首次发现椰子织蛾。目前,该虫已在海南多个市县及广东和广西危害,对我国棕榈科植物的安全生产构成严重威胁。2014年11月,作者等人在万宁兴隆和三亚海棠湾镇调查椰子织蛾危害时,发现其重要天敌昆虫——褐带卷蛾茧蜂。为了进一步了解褐带卷蛾茧蜂,本文对其形态特征、分布、寄主和生物学习性进行了报道,以便更好地用于椰子织蛾的生物防治。
