鄂西春玉米地节肢动物群落种类的调查

Investigation of the Composition of Arthropod Communities in Spring-Corn Fields at Western Hubei Province

对鄂西春玉米地节肢动物群落的种类进行了系统调查与形态鉴定。结果表明,当地春玉米地节肢动物种类多达74种,隶属2纲15目44科。其中昆虫纲有13目39科67种,蛛形纲有2目5科7种。昆虫纲中又以直翅目、鳞翅目、鞘翅目、同翅目和膜翅目等5目中昆虫物种数较多。

The composition of arthropod communities in spring-corn fields at western Hubei Province was investigated. A diverse community that about seventy-four species of arthropods, belongmg to 2 Classes, 15 Orders and 44 families was found in the field. Thirteen orders, thirty-nine families and six- ty-seven species were in Insecta,and two orders, five families and seven species were in Arachnoidea. In- sects in Orthoptera, Lepidoptera, Coleoptera, Homoptera and Hymenoptera were the main species. Knowing about the main pest and natural enemy species of arthropod community in western Hubei Province could provide valuable information for protecting natural enemy resources of the pests in the spring-corn fields in this region and for conducting research on the diversity of arthropods of these fields.
