闽东地区种植的茉莉花,其花产量和质量均居全省之首,且近几年茉莉蕾螟危害严重,造成产量锐减,质量下降。为此,进行对茉莉蕾螟的生活习性、发生规律及其防治方法的研究,将有助于闽东地区茉莉花生产的发展。 一、茉莉蕾螟分布及其危害 茉莉蕾螟Neohendecasis sp.(俗称花蕾虫、花心虫),鳞翅目,螟蛾科。在我国分布在广东、广西、江西、江苏、安徽、四川、湖北、浙江、福建等省局部地区的柑桔、梨、桃、李等多种果花树田间,为害茉莉花蕾最为严重。茉莉花蕾被幼虫蛀食空后,粪便排在花蕾外,使花蕾不能正常伸展,逐渐萎缩、枯焦。笔者调查溪柄地区茉莉花园,为害率可达5~40%。
The jasmine planted in the eastern part of Fujian Province ranks first in the province in terms of flower yield and quality. In recent years, the jasmine lacewing borer is seriously endangered, resulting in a sharp drop in output and a decrease in quality. To this end, the study on the habits, the occurrence of law and its prevention and control methods of the jasmine laceworm, will contribute to the development of jasmine in the eastern part of Fujian Province.
