THE DEGREE OF ATTACK PRODUCED DURING STORAGE BY Sitophilus granarius ON SOME WHEAT GENOTYPES

Abstract

This paper presents the attack by the wheat weevil during seed storage. Sitophilus granarius is an important pest of stored cereals because it causes great damage by destroying the embryo and affecting germination. The biological material consisted of 10 winter wheat genotypes, 8 varieties and 2 lines. The material was analyzed and the frequency of attack, intensity and degree of attack produced by the pest were determined for each genotype in 4 repetitions. The aim of the study was to determine whether there are differences in attack between the studied wheat genotypes. Following statistical analysis, both distinctly significant positive and highly significant positive differences were obtained between the studied wheat genotypes, compared to the Miranda control.
