abstract
Laboratory studies were conducted to determine total protein, lipid and carbohydrate concentrations of adults 15 species belong to 12 genera (Coleoptera: Curculionidae). Due to the structural elements of the protein, protein amount has been founded high in all species. On the other hand carbohydrate has been founded low in all treated species. These results indicated that there is no relationship between the wet weight and the amount protein, lipid and carbohydrate. Also, protein, lipid and carbohydrate levels showed some variations even in the same genera.
