摘要
通过野外调查和室内饲养观察,对桉树枝瘿姬小蜂的成虫羽化、生活史、越冬情况、年虫口变化、生活习性等生物学特性进行了初步研究。该虫在广西博白1 a发生4~5代,世代重叠,以4~5代虫瘿(含各种虫态)越冬,3—7月为成虫羽化高峰和扩散期,全年大部分时间均有成虫羽化。
Based on the field investigation and laboratory observation, the bionomics such as the adult eclosion, life cycle, overwintering situation, annual fluctuation of the population and life habits of Lepto- cybe invasa were studied. The insect had 4 or 5 generations a year and the generations overlapped. It overwintered as wasps of the 4th-5th generations including all instars in galls in Bobai of Guangxi Province. The peak of adult eclosion occured between March and July. The eclosion lasted most of the year.
