对花生田昆虫群落进行了系统的调查,并分别运用自然系统分类法、生态功能分类法及优势度进行归类分析,基本搞清了花生田的昆虫群落结构。结果表明:花生田昆虫群落由8个目34个种组成,主要的目为鞘翅目(Coleoptera)和直翅目(Orthoptera);棉蚜(Aphis gossypii)、大猿叶甲(Colaphellus bowringi)、棉叶蝉(Amrasca biguttula)、灰飞虱(Laodelphgax striatellus)是花生田昆虫群落的优势种,是主要的防治对象;昆虫群落结构根据生态功能可以分为3个功能团,即植食性昆虫、肉食性昆虫和卫生性昆虫,其中植食性昆虫数目最多、危害也最重,对花生的产量和品质的影响最大,所以必须采用相应的措施加以防治。
The pest insect community in Peanut Field was systematically investigated, and the taxonomic classification of peanut fields was conducted by using the classification of natural systems, the classification of ecological functions and the dominance degree. The insect community structure in peanut fields was basically ascertained. The results showed that the insect community in Peanut Field consisted of 8 orders and 34 species. The main species were Coleoptera and Orthoptera, Aphis gossypii, Colaphellus bowringi, Amrasca biguttula and Laodelphgax striatellus are the dominant species of insect community in peanut field, which are the main control objects. Insect community structure can be divided into three functional groups according to ecological functions, namely herbivorous insects, carnivorous Insects and hygienic insects, of which the largest number of herbivorous insects, the most harmful, the peanut yield and quality of the greatest impact, it must be taken to prevent and control the corresponding measures.
