摘要
20 0 3年3月～2 0 0 4年5月,分别在南充市郊的人工林、农田、河漫滩草丛、灌木丛4种生境进行瓢虫种群结构及多样性的抽样调查研究,共采集瓢虫标本1 2 1 6只,经鉴定隶属7亚科,2 2属,3 6种。个体数量以瓢虫亚科最多,食植瓢虫亚科次之。物种数以瓢虫亚科最多,食植亚科次之,小艳瓢虫亚科最少。各生境的多样性指数和物种丰富度排序为灌木丛>河漫滩草丛>人工林>农田。
The population structure and diversity of ladybeetles in four habitats: the man-made forest, agricultural fields, bushes, and beach plants were surveyed from March 2003 to May 2004. Of the total ~1?216 lady beetle specimens collected,36 species of 22 genera in 7 subfamilies were identified. Two subfamilies predominated: Coccinellinae (genera: Propylea, Harmonia, etc.) and Epilachninae(genera: Epilachna, Henosepilachna, etc.). Among the genera, Epilachna had the most abundant species. The subfamily Coccinellinae was the most abundant in terms of individuals, and Epilachninae was the next. Afidentula was the least abundant in terms of number of species or individuals. Species richness decreased in the following sequence: bushes, beach plants, the man-made forest, and agricultural fields.
