广东柑桔上八种凤蝶幼期特征的鉴别

Morphology of the Egg, Larva and Pupa of Eight Species of Papilionidae Injurious to Citrus in Guangdung Province

柑桔凤蝶类是为害柑桔新梢和嫩叶的重要害虫。笔者经多年在广东各地采集,饲养观察,发现在广东为害柑桔类的风蝶有下列八种:(1)桔黄凤蝶Papilio xuthus Linnaeus;(2)玉带凤蝶Papilio polytes Linnaeus;(3)黄花凤蝶Princepe demoleus Linnaeus;(4)黄绿凤蝶Papilio memnon Linnaeus;(5)纵带凤蝶Papilio halenus Linnaeus;(6)蓝凤蝶Papilio protenor Cramer;(7)碧凤蝶Papilio bianor Cramer;(8)巴黎绿凤蝶Papilio paris L.发生量多,分布广,为害严重的是前三种。每年发生5—6代,以4—9月发生较多,幼虫为害柑桔类的春、夏、秋梢。本文对柑桔凤蝶类幼期特征进行鉴别,有助于今后了解不同种类凤蝶的生活习性和发生规律的研究及防治工作,可省去养出成虫这个环节。

This paper described eight species of Papilio injurious to citrus in Guangdung Province. They are: (1)Papilio xuthus L.(2)P. polytes L. (3)Princeps demoleus L. (4)Papilio memnon L.(5)P. halenus L. (6)P. protenor Crarner(7)P. bianor Cramer. (8)P. paris L..The first three species are more common and often causes serious injury to the young leaves and buds.
