摘要
通过对南阳市园林绿地植物7~8月份诱虫灯下昆虫群落的调查,摸清了其常见的昆虫种类,结果表明：园林绿地植物灯下昆虫群落包括5个目,21科,50种;其中有害虫45种,害虫天敌4种和杂食性昆虫1种.同时,根据害虫的发生数量及对园林绿地植物的危害程度,从群落的角度分析了园林绿地植物害虫的优势种（类）,主要有暗黑鳃金龟、淡剑夜蛾、茶长卷蛾、斜纹夜蛾、土蝽等;从生态功能分类的角度把这些绿地害虫分为植食性昆虫、肉食性昆虫、传粉昆虫、杂食性昆虫4大类,其中这些害虫主要来自于鳞翅目、同翅目、直翅目、鞘翅目、半翅目五个目,为园林绿地植物在群落水平上进行综合治理提供了理论依据.
Preliminary investigation on the structures of insect community with the alluring insect lamp in Nanyang was carried out,and the parts of organism communities were clarified.The results showed that these insect communities of landscape plants consisted of 5 orders,21 families,and 50 species,and there were 45 species of the pests,4 species of the natural enemy insects and 1 species of polypgagous.Meanwhile,according to the quantity of the pest occurred and the degree of the landscape plants damage,the dominant species of the pest in the landscape plants were analyzed from the view of communities,and the main species were Holotrichia parallela,Sidemia depravate,Homona magnanima,Podenia litura,Cydninae and so on.These insects,which were belong to Lepidoptera,Homoptera,Orthoptert,Coleoptera,Hemptera,were divided into phytophagous insects,insect-pollinators,omnivorous insects,carnivorous insects and underground pests.The theoretical basis of IPM to the landscape plants in the level of community could be provided by this investigation.
