西双版纳南览河流域常见观赏蝶种及其寄主植物资源调查

Investigation on Resources of Common Ornamental Butterflies and Their Host Plants in Nanlan River Basin of Xishuangbanna

西双版纳勐海县境内南览河流域具有良好的天然植被,蝴蝶种类繁多。为了开展重要观赏蝶种的人工繁育试验,2013-2018年对南览河中低海拔地带的常见观赏蝴蝶及其野生寄主植物资源开展了进一步的深入调查,结果表明,经过5年定点调查和沿线观察,在区域内发现兼具较高观赏价值及人工繁育潜力的蝶种46个;通过观察野外成虫的产卵活动,结合野外套袋及室内饲养幼虫,发现蝴蝶寄主植物38种,初步查明了相关蝶种的野生寄主植物资源。调查工作可为筛选出当地适生优良寄主植物、进一步开展相关蝶种的人工养殖试验提供参考。

The natural vegetation is well preserved along the Nanlan River of Menghai County in Xishuangbanna.It breeds a variety of butterfly species.In order to conduct the artificial breeding experiment of important ornamental butterfly species,a further in-depth investigation was carried out on the common ornamental butterfly and its wild host plant resources in the low and middle altitude area of Nanlan river from 2013 to 2018. During five years of fixed-point investigation and linear observation,46 butterfly species with high ornamental value and artificial breeding potential were found.Through observing the oviposition activities of adult butterfly in the field,combining with field bagging and indoor larvae rearing,38 species of butterfly host plants were found,and wild host plant resources of related butterfly species were preliminarily identified.The investigation could provide a basis for screening the suitable host plants and conducting further artificial culture experiment of related butterfly species.
