Abstract

Description of the subject:The harmfulness of Capnodis tenebrionison fruit trees is difficult to control due to the encrypted larval stages. It is important to know the cycle of development of this insect in order to fight against them. Objective:Study of the adaptive C.tenebrionisbehavior to its host plants through their nutritive components that influence its population dynamics.Methods:Manthly readings spread were carried, abundance (washing and adult) and lipid energy reserves of C. tenebrionis. Nitrogen, cellulose, hemicellulose, lignin, phenols, protein levels were quantified in the two species of attacked Prunus.Results:C. tenebrioniswas more abundant in Prunus domestica.(L., 1753)The cellulose content and the synergistic effect between protein and nitrogen contributed to this abundance that resulted in a better conversion into lipids in developing larvae on P. domestica.The larvae which developed on Prunuscerasus(L., 1753) have been disadvantaged by the high phenol concentrations and presented a delay in their development cycle. Conclusion:Our results showed that the phytochemical changes were an important aspect that highlights the adaptability of this insect
