Contributions to the Knowledge of Morphology of the Granary Weevil (Sitophilus Granarius L.), Major Pest of the Stored Cereals

To solve the multiple practical aspects raised by the achieving of cereals stocks protection (especially wheat and corn) against granary weevil Sitophilus granarius L., the research aimed a complex study on the sexual dimorphism at this species, aspect which help to prevent the weevils damages using unpollutant methods (with the aid of sexual pheromones, ovogenesis inhibitors, etc.). Due to the summarily data in the scientific literature of the world refering to the sexual dimorphism of the species, a detailed study was made within the Entomology Laboratory at the Faculty of Agriculture of USAMV Cluj-Napoca and at the Center of Electronical Microscopy of Babeş-Bolyai University in Cluj-Napoca (Romania), during 2005-200
