河南省夜蛾科、尺蛾科和天蛾科昆虫区系研究

Study on Fauna of Noctuidae,Geometridae and Sphingidae Insects in Henan Province

通过调查和采集,共发现河南境内夜蛾科、尺蛾科和天蛾科昆虫344种,隶属于196属,22亚科。区系分析结果表明:(1)在世界昆虫六大区系中,河南三科昆虫属15个分布型。以古北区系种类最多,占34.30%;古北和东洋区系种类居第二,占33.14%;东洋区系种类居第三,占18.31%。(2)在中国昆虫区划中,可分成35个分布型。以华北和华中区均有分布的种类最多,占59.88%:东北和华北区均有分布的种类居第二,占49.13%;东北、华北和华中区均有分布的种类居第三,占30.52%。(3)发生平原地区的种类比山区或丘陵地区多,黄淮平原亚区的种类最多,伏牛山北坡山地丘陵亚区的种类最少,这与当地的生态环境和植物相有关系。(4)伏牛山、黄河阻隔某些夜蛾科昆虫在其南北麟(岸)的分布有一定的作用。

344 species and subspecies of N octuidae,Geometridae and sphingidae insectsin Henan province are dealt with.They belong to 196 genera,22 subfamilies.The result of fauna analysis indicates:1.in the wolrds insect fauna,the threefamilies with 344 species is divided into 15 distribution patterns.The species ofPalearctic Fauna ranks first,accounting for 34.3%,Paiearctic and Oriental Faunasecond,33.1%,and Oriental Fauna third,18.3%.2,In Chinese insect fauna,it is divided into 35 distribution patterns.It is mainly distributed over Huabei,Huazhong and Dongbei regions 3,The species occurring in plain areas is morethan those in mountainous and hilly regions. Funiu Mountains and yellow Riverplay some role in limiting the distribution of certain species of Noctuidae insec-ts.
