河北、河南和安徽省夜蛾科昆虫区系研究

Studies on Fauna of Noctuidae Insects in Hebei, Henan and Anhui Province

对河北、河南和安徽省夜蛾昆虫区系的分析结果表明:(1)在世界昆虫区系中,河北省夜蛾以古北界种类最多,占47.4%;古北和东洋界共有种类次之,占39.5%。河南省夜蛾以古北界种类最多,占34.8%,古北和东洋界共有种类次之,占26.1%。安徽省夜蛾以东洋界种类最多,占37.3%;古北和东洋界共有种类次之,占33.9%;。(2)在中国昆虫区划中,河北省夜蛾以在东北和华北区均有分布的种类最多,占67.89%,在华北和华中区均有分布的种类次之,占50.53%。河南省夜蛾以华北和华中区均有分布的种类最多,占63.48%;东北和华北均有分布的种类次之,占45.22%。安徽省夜蛾以西南和华中区均有分布的种类最多,占47.21%,华北和华中区均有分布的种类次之,占46.35%。(3)就这三个省份来讲,自北向南夜蛾科昆虫种类增加,古北界种类减少,东洋界种类增加。

The results of fauna analysis of Noctuidae insects in three provinces indicate: 1. In the world insect fauna, the noctuid species of Palearctic Realm ranks first, accounting for 47.4%, followed by that of Palearctic and Oriental Realm making up 39.5% in Hebei. As for Henan and Anhui, the former species are also the first in number, 34.8%. and 12%,and the latter the second in number,26.1%and 33.9% respectively, 2. In the noctuid species, distributing over Northeast and North China, is the most in Hebei with Henan keeping the second place of that covering the north and middle parts of China, and Anhui the third over the southwest and middle parts of China, 67.89%, 63.43% and 47.21% respectively. 3. According to the date from the three provinces, it can be seen that the species of Palearctic Realm increases, and the species of Oriental Realm decreases from south to north.
