An experiment was conducted to study the influence of physical characters of pods on ovipositional preference of Callosobruchus chinensis (L.) under laboratory conditions. The data on physical characters of pods revealed that pod length was maximum in cowpea (14.13cm) and minimum in chickpea pods (2.38cm). Cowpea pods had the maximum number of trichomes (14.16/mm2) followed by chickpea (8.16/mm2), black gram (6.66/mm2) and green gram (4.16/mm2). Pod wall thickness was highest in cowpea pods (0.73mm) followed by black gram pods (0.58 mm). Pod wall thickness of green gram and chickpea pods was same i.e. 0.51mm. Correlation analysis between ovipositional parameters of Callosobruchus chinensis (L.) and morphological parameters of pods revealed that eggs laid, hatchability percentage and adult emergence had a negative correlation with trichomes number/mm2 and pod wall thickness, whereas pod length showed a positive correlation with eggs laid, hatchability percentage and adult emergence percentage.
