After analysis of multiple sequences alignment, phylogenetic tree and similarity of sequences, it was shown that Ac-ASP has similar relation with Am-ASP, and shared high homology with other Hymenopteran and Coleopteran. From above analysis, we firmly suggest Ac-ASP1 and Ac-ASP2 belong to OBPs family and Ac-ASP3 belong to CSPs family.

For more investigation on the linkage-structure of elytra, the opening-closing process of elytra is recorded. Besides, the strength of linkage between the elytra was measured, and Protaetia brevitarsis has the strongest coupling force. At last, the elytra linkage-structure model was analysed by simulating its movement and analyzing its structure using Pro/Engineer, it is proved that the structure is especial and efficient.

This thesis focuses on beetle Cybister tripunctatus in addition to some other species of beetles and studied the elytron's micro-structure. We found that there are many concaves、hollows and holes on its structure; the configuration of this material is compound samdwich; the linkage-structure between elytra adopts the concave-protuberant mesh joint with some bristle.
