兼营室外生活的储藏物昆虫种类调查

SURVEY ON STORED PRODUCT INSECTS LIVING OUTDOORS

在河南省郑州市居民小片菜地的菜花、广场和路边的草丛中、室外的腐烂水果,蔬菜、鸡毛、骨头以及空中捕捉和食物诱捕,采集到44种储藏物昆虫。它们录属于草翅目(Dermaptera)、鳞翅目(Lepidoptera)和鞘翅目(Coleoptera)的17个科,其中鞘翅目的种类最多,并且是重要储藏物害虫。调查结果表明,储藏物昆虫的很多种类兼营室外生活,尤其在成虫期,它们在室外飞行、爬行、觅食和交尾,极易进入室内在储藏物上产卵,其幼虫严重地危害储藏物。因此,对储藏物害虫种类的调查和防治工作有重要影响。

An investigation on stored product insects living outdoors was made in Zhengzhou city. The specimens of 44 species of stored product insects were collected in various places outdoors from various resources like the flower of vegetable, the putrid vegetable and fruits, the rotten bones and feathers, the dead body of small animals, etc. These insects were subordinate to 17 families of Dermatptera, Lepidoptera and Coleoptera, among which Coleoptera was the important stored product insects and the Number 1 in species. The result shows that many species of stored product insects have habitat both indoors and outdoors, adults in particular. They fly, crowl, look for food and mate outdoors, very likely to come indoors to oviposit on the stored products. The larvae incur serious infection on the stored products, which greatly influences the investigation and the control of the stored product insects.
