摘要
本文对不同生态桃园昆虫群落及其多样性进行了研究。研究结果表明,桃园有昆虫60种(包括螨类),隶属于10目(包括蜱螨目),42科;主要类群为鞘翅目(Coleptera)、双翅目(Diptera)、同翅目(Homoptera)、鳞翅目(Lepi-doptera)、膜翅目(Hymenoptera)、半翅目(Hemiptera)和蜱螨目(Acarina)。不同生态桃园昆虫群落科数、物种数、多样性指数、均匀性及优势度等均有不同的程度的变化。主要优势种为桃小绿叶蝉(Empoasca flavescens Fabr.)、桃粉蚜(Hyalopterus amygdale Blanchard)和山楂叶螨(Tetranychus viennesis Zacher)。由群落的相异系数可知,桃园8月上旬与8月中旬的昆虫群落最为相似。
Insect communities in the 2 type peach orchards were systematically investigated. The results showed that there are 60 species, belonging to 10 orders and 42 families ;The insects of Coleptera, Diptera, Homoptera, Lepidoptera, Hymenoptera, Hemiptera and Acarina were the dominant species,the number of individual, the dominance, diversity and evenness varied in the peach orchards with the time; the dominant species were Empoasca flavescens Fabr, Hyalopterus amygdale Blanchard and Tetranychus viennesis Zacher. According to the results of similarity, the insect community of Early - August and that of Mid - August were the most similar.
