RESEARCHES CONCERNING THE EXTERNAL MORPHOLOGY OF GRANARY WEEVIL’S ADULT(SITOPHILUS GRANARIUS L.), A MAJOR PEST OF THE STORED CEREALS

Within the technology of cereal products, prevention and controlling the weevils, pests of stored cereals is a major problem. 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 morphology at this species, aspect which help to prevent the weevils damages using unpollutant methods (with the aid of the ovogenesis inhibitors, desicants, intense electrical fields, etc.). The studies concerning the external morphology of adult, were made with the aid of stereomicroscopes at the Entomology Laboratory of Faculty of Agriculture at USAMV Cluj-Napoca and the material has been photographed using optical and Electronic Scanning Microscope at the Center of Electronical Microscopy of Babeș-Bolyai University in Cluj-Napoca, during 2005-2007.  In the paper there are presented the morphological aspects of the granary weevil’s (Sitophilus granarius L) adult in stored wheat. These aspects are completed by some original photos and a detailed study of the adult stage of species.
