Comparative study of the glycosidases of 2 Lepidoptera wood-eating Cossidae (Cossus cossus L., and Zeuzera pyrina L.) and various wood-eating Coleoptera]

The authors present here the results of their research concerning the study of the osidases of the caterpillars Cossus cossus L. and Zeuzera pyrina L. (Lepidoptera Cossidae). Its enzyme equipment shows very important differences compared to the different species of Scolytidae, Cerambycidae, Curculionidae and Buprestidae. The differences are lie especially in the absence of some osidases acting on polysaccharides (hémicelluloses and cellulose).
