from Indonesia, Nigeria, and Yemen, and C. chinensis strains from Indonesia and Kenya on cowpea and
green gram were studied at 20°C and 70% relative humidity.
Variations on ovipositional behaviour were found among C. maculatus as well as among C. chinensis
strains. Variations on developmental period were found only among C. maculatus strains. The developmental
period of Callosobruchus spp. was shorter on green gram than that on cowpea. Density effect was remarkably
found only on adult survival of C. maculatus Yemen strain. These results make useful contribution to the
species biology, and have important implication if strains of these species are accidentally imported to
countries, or when new legume crops are introduced.
