【摘要】 为明确中国东锤角叶蜂(Orientabia sinica Wei et Yan)的生物学特性及对园林花卉植物锦带花的为害情况,通过野外观测和室内饲养的方法对该叶蜂的生活习性等进行了系统调查研究。结果表明:中国东锤角叶蜂在吉林省1年发生1代,以老熟幼虫结茧在树下土中越冬;每年5月中旬成虫大量羽化出土,在锦带花叶片背面表皮下产卵,幼虫于5月下旬至6月中旬严重为害锦带花的叶片、花朵。作为吉林省新记录种和园林花卉植物锦带花的新害虫,文中描述了该叶蜂各虫态的形态特征,并根据其当地的发生规律提出了具体防治建议。更多还原

【Abstract】 In order to clarify the biological characteristics of Orientabia sinica Wei et Yan and its damage to garden plant Weigela florida,the life habits of the Orientabia sinica Wei et Yan were systematically studied through field observation and indoor breeding. The results showed that Orientabia sinica Wei et Yan had only one generation each year in Jilin province and overwintered in the soil beneath the trees as cocooned mature larvae. Every year in mid-May,the adult eclosion started and the adults laid eggs on the backside of Weigela florida leaves. When the larvae came out from lateMay to mid-June,they would cause great damage to the leaves and flowers of Weigela florida. As a newly recorded species in Jilin province as well as a new kind of insect harmful to garden plant Weigela florida,its biological characteristics at different developmental stages werer described,and some concrete controlling measures were put forward according to its occurrence law.更多还原
