Varietal Susceptibility of Mungbean Genotypes to Pulse Beetle, Callosobruchus analis (Fabricius) (Coleoptera: Bruchidae)

The susceptibility of 5 mungbean ( Vigna radiata Wilczed) genotypes to pulse beetle, Callosobruchus analis, were studied under laboratory conditions. No mungbean genotype was found immune to pest infestation, and they showed different magnitude of weight loss. Based on the criteria of mean pest population and weight loss, genotype No. 25/20 appeared more susceptible, whereas AEM-6/20 was more tolerant/ resistant to bruchids infestation than other genotypes. The peak population of insect and % weight loss were in No. 25/20, followed by L1 P5/5/89, No. 30/5/8/90, AEM-96 and AEM-6/20. The mean grain moisture ranged from 9.94 to 11.37% that was found conducive for pest multiplication. Consequently the insect resistant and high yielding varieties are a gift for alleviation of storage losses and should be used in future breeding programmes.
