金龟甲总科昆虫食性的调查研究

Feeding Habits of Scarabaedidea

对金龟甲总科昆虫食性的研究结果表明,在58种金龟甲中,植食性类群有32种,腐食性类群有17种,杂食性类群有9种。不同食性类群的生态功能各异,植食性类群为害植物,腐食性类群不为害植物,且能净化环境与维持生态平衡,杂食性类群则具有既为害植物,又捕食害虫双重功能。

In this paper feeding habits of scarabaeoidea have been studied on the basis of outer investingation and speices identification and refrence to relative information by community and ecological function. Tile results showed that in the 58 species of scarabecidea indentified, there are 32 groups of phytophcegous, 17 groups of saprophagous,9 goups of omnibvrous. Ecological functions differs from each other according to differeat feeding habits,Groups of phytophaeoidea is harmful to plants, groups of saprophagous do no harm to plants which can clean environment and keep ecological balance, groups of omnivorous eats plants and pest.
