铁岭、南昌夜蛾科昆虫区系结构比较

本文从夜蛾科各工科在辽宁铁岭、江西南昌两地的种数及比重;夜蛾科昆虫区系类型及所占比重;两地夜蛾科昆虫在中国动物地理区划中的归属及所占比重以及两地与国内外几个地点的夜蛾科昆虫比较等四个方面来说明铁岭、南昌两地夜蛾科昆虫区系结构的异同。结果可以明显地看出:铁岭夜蛾科昆虫,绝大多数属于古北界种,所占比重几乎接近100％;而南昌则以东洋界种占较大优势,所占比重约72.9％。与国内几个地点比较,铁岭与黑龙江的共有种最多,占87.01％;而南昌同四川的共有种最多,占60.24％。与国外比较,铁岭、南昌两地均与日本共有种较多,分别占80.23％及78.71％。

Comparison of Faunal Structure of Noctuids Between Tieling and Nanchang,China

Comparing the faunal structure of noetuids in Tieling with that in Nanehang, we discovered that almost all of the noctuid species in Tieling belonged to the Palaearctic Region, and that a large part of noetuid species in Nanehang belonged to the Oriental Raelm, with the percentage rates of Palaearetic Region noctuids and Oriental Realm noctuids in the two regions standing at approximately 100% and 72. 9% respectively. Furthermore, we compared the noctuids in several localities elsewhere in China and abroad with those in Tieling and Nanchang to calculate the rates of shared noctuid species. We found that the fauna in Tieling was similar to that in Heilongjiang, while that in Nanchang similar to that in Sichuan, with the rates of shared species registered at 87. 01% and 60. 24% respectively. And the rate of species shared by Tieling and Japan was 80. 23%, by Nanchang and Japan 78. 71%.
