对南京储烟昆虫群落的初步研究

A preliminary study on Nanjing insect community on stored tobacco

１９９２年４月到１９９３年４月对南京仓储烟叶及露天垛储存烟叶上的昆虫群落进行了研究。从分类类群及生态功能上对这两类昆虫群落的结构进行了分析和研究，估计出了它们各自包含的物种数及最大可能漏查的物种数，确定了常见种和优势种；计算和分析了这两类群落物种的时间生态位宽度和时间生态位重叠指数；对储烟昆虫群落的多样性指数和均匀性指数也进行了计算和分析，最后研究了储烟昆虫群落的季节格局，并组建了群落及优势种的消长模型。

Studies of stored tobacco insect communities were carried out both in a storehouse and an open-air depository from April, 1992 to May, 1993 in Nanjing. Structures of two insect communities were analyzed according to their classification and ecological function of the communities. The number of species and the maximum number of possible missing species in these two communities were estimated by Jackknife method. The dominant species and common species were determined. The temproal niche breadth and niche overlap of the species within two communities were calculated and compared. Diversity and evenness indexes of two communities were calculated and discussed, too. The seasonal patterns of stored tobacco insect communities were discussed and analyzed. Finally,the dynamic models of these two communities were constructed.
