The most effective, environmentally sound and safety way to fight pests with biological means is the use of resistant varieties to them. In the present study were indicated the reactions of 30 Bulgarian common bean genotypes to the most economically important enemy – bean weevil (Acanthoscelidis obtectus Say). For this purpose, the following indicators were traced – seed damages and young adult insects, which largely characterized the response of different common bean genotypes to that biological pest enemy. The results of this investigation present a sensitive response to the sustainability of different genotypes to the bean weevil. The Bulgarian common bean varieties Plovdiv 11M, Abritus, Crystal and Bulgari can be used in breeding programs as donors of resistance to the bean weevil.
