Implications of developmental parameters of Pulse beetle, Callosobruchus chinensis (L.) on resistance screening of chickpea genotypes

Lovely Kumari, Mohammad Abbas Ahmad and Pankaj Kumar

Callosobruchus chinensis (L.) is one most the devastating pests of chickpea. The effect of developmental parameters of pulse beetle, Callosobruchus chinensis (L.) was investigated on 15 chickpea genotypes and was found to differ significantly among the test genotypes. The highest fecundity was observed in C1025 (97.22 eggs/female), while minimum in C1021 (46.82 eggs/female). Percent loss in seed weight varied from maximum of 47.76% on C1025 to minimum of 09.81% on C1147. The adult emergence percent was least on C1088 (59.14%) and it was recorded to be maximum on C1022 (76.22%). The longest development time was observed on C1021 (30.06 days). The growth index for C. chinensis on the test genotypes varied from 2.09 to 3.10, with maximum on genotype C1120 and minimum on BG256. The comparison of growth index and per cent adult emergence of the insect demonstrated that BG256 was the most tolerant genotype to this pest with performance at par with 7 other genotypes, while C1120 was found to be highly susceptible.
