柑橘凤蝶形态特征及年生活史研究

Studies on Morphological Characteristics and Annual Life History of Papilio xuthus Linnaeus

摘要: 野外采集卵、幼虫，在玻璃温室内供以幼虫寄主植物、成虫蜜源植物饲养，第２、３代及越冬代皆为第１代后代，观察研究柑橘凤蝶各虫态、各虫龄与发育历期．结果表明，柑橘凤蝶在郑州地区一年可完成３代，卵期为５～７ｄ，幼虫５龄，幼虫期１５～２４ｄ，蛹期９～１５ｄ，越冬蛹期１４０～１５６ｄ，成虫期１０～１２ｄ．同时记录、描述了柑橘凤蝶各虫态、幼虫５个龄期外部形态及生物学习性.

Abstract: Eggs and larvae of Papilio xuthus Linnaeus collected in the wild were fed by host plant and offered by adults nectar plants. Their descendants were used of the sources of second, third and overwintering generation. The results showed that Papilio xuthus Linnaeus could complete 3 generations in Zhengzhou area, egg stage is 5 ~7 days, larva stage is 15 ~24 days, pupa stage is 9 ~15 days, and the over⁃wintering pupa stage is 140 ~156 days, adult stage is 10 ~12 days. At the same time, the morphological characteristics of egg, 5 instars of larva, pupa and adult were given.
