The laboratory assessment of host specific developmental study of Callosobruchus maculatus reared on stored grain pulses

The experiment was conducted in the BOD incubator with a standard temperature (27.6 ± 2.5°C) and relative humidity (70.2 ± 1.03%). The biotic performance was determined on the basis of different variables and also varied among pulses. The Highest average fecundity per female (71.33) of Callosobruchus maculatus was found in cowpea and lowest on red lentils (26.00). The highest were laid in the initial two days of oviposition and continues for up to 8 days. The total developmental duration ranged from 38 - 62 days. Among all pulses, cowpea seeds were highly preferred for oviposition but hatchability and adult emergence was found higher in black gram seeds. While kidney bean seeds do not show any infestation of C. maculatus.
