- Abstract
Investigations were carried out on the "Relative susceptibility of different lentil varieties against pulse beetle, Callosobruchus chinensis (Linn.)" during 2014-15 at S.K.N. College of Agriculture, Jobner. Out of 10 varieties screened on the basis of biological parameters and physico-chemical characters against this insect, Asha and PL-01 were less susceptible and Spana, IPL-81 and L-4076 were highly susceptible. However, PBW-343, L-147, RKL-60701, JL-3, RKL-607 and RKL6118 were moderately susceptible. It was evident from the correlation coefficient that the grain size had a significant and positive correlation with grain damage and weight loss. The grain hardness had a significantly negative correlation with damaged grains and grain weight loss. Thus, it is clear that the increase in grain hardness decreased the level of infestation and viceversa. The moisture contents of the grains were observed to be correlated significantly and positively with the infestation by C. chinensis. Thus, the population and infestation of the pest increased with the increase in moisture contents.
