Abstract:By observing and comparing the larval external morphological structures of 16 cerambycid species belong to 3 subfamilies of Cerambycidae, the adaptability of external morphological structures and harming habits is preliminarily summarized. The results show that the larvae of subfamily Cerambycinae had gouge-shaped mandible, and the larvae of subfamily Lamiinae and Aseminae had wedge-shaped mandible. For the larvae with gouge-shaped mandible, the smaller of the area ratio of its exerted-visible mandible to head, the stronger its mandible is. For the larvae with wedge-shaped mandible, the larger of the area ratio of its exerted-visible mandible to head, the stronger its mandible is. The pronotum and ambulatory ampullae in the larvae which timely discharged faeces and sawdusts are more developed, with tough and big verrucae, and the relative area of their spiracles are relatively larger. Contrarily, the promotum and the ambulatory ampullae in the larvae which did not timely discharged faeces and sawdusts are less developed, and they had fine wrinkles, and the relative area of their spiracles are relatively smaller.
