Abstract
Abstract The susceptibility of eleven locally purchased pulses against cowpea weevil, C. maculatus (F.) (Bruchidae: Coleoptera) was determined on the basis of different variables. Oviposition remained independent of insect growth and development. The developmental period was reduced on susceptible, as compared to resistant, pulses. On the basis of such variables as the number of adult progeny, adult longevity and weight, seed weight loss and damage, mungbean (Vigna radiata) mash (Vigna mungo) gram (Cicer arietinum) (Kabli white) and small bean (Vigna sinensis) were found to be susceptible while french bean (Phaseolus vulgaris) lentil (Lens culinaris) soybean (Glycine max) and gram roasted (Cicer arietinum) (black seeded) were highly immune to this pest. Other pulses, peas (Pisum sativum) gram split (Cicer arietinum) (black seeded) and gram (Cicer arietinum) (black seeded) showed little susceptibility. There was also correlation between the variables.
