蜡彩袋蛾生物学与生态学特性初步研究

作者:杨亚蓉 刊名:生物灾害科学 上传者:葛兴全

【摘要】2014-2017年,对龙海市浮宫镇蜡彩袋蛾(Chalin larminati Hevlaerts)的发生为害情况、形态特征、生活史和天敌情况等进行了系统调查。结果表明,蜡彩袋蛾在福建省龙海市1年发生1代,以老熟幼虫在袋囊中越冬。野外调查结果发现,该虫主要危害香樟、洋蒲桃、树葡萄和脆桃等树木,而对荔枝、龙眼和金煌芒果等危害较轻。试验中偶然发现了蜡彩袋蛾寄生天敌——绒茧蜂,该蜂成虫羽化期和蜡彩袋蛾羽化期基本吻合,且对蜡彩袋蛾幼虫的寄生率较高,对抑制害虫大发生,具良好的控制作用。

The occurrence, morphological characteristics, life history and natural enemies of the pest were investigated systematically. The results showed that the moth occurred 1 generation per year in Longhai, with the instar larvae wintering in bags. Field investigation results also showed that the major insect hazards were Cinnamomum camphora, Syzygium samarangense, Plinia cauliflora and crisp peach trees, while the lighter hazards were Litchi, Dimocarpus longan and mango. Braconid, a kind of natural parasitic enemy, was found in
