Life table of Bracon hebetor on rice moth, Corcyra cephalonica Stainton (Lepidoptera: Pyralidae)

Abstract

Existence desk take a look at can be very beneficial for designing mass rearing applications in addition to identifying the timing of creation in inoculative releases. in the gift look at maximum obvious mortality in the course of the egg degree turned into 30 eggs. Highest mortality rate become registered in larval level with fifty two larvae. The quantity that survived from 126 eggs to adult emergence turned into 96 individuals. Women deposited first batch of eggs on thirteenth day and stopped it after twenty first day with lx values being zero.98 and 0.56, respectively. The lx decreased gradually after 14th day of pivotal age because of adult mortality. The women contributed highest wide variety of progeny (mx = 10.zero) inside the life cycle on the thirteenth day of pivotal age. The net reproductive ability (Ro) turned into worked as fifty one.27 women/ woman with the imply technology time (T) of 15.ninety six days. The intrinsic charge of increase (rm) and finite price of natural increase in numbers (λ) changed into 0.2466 and 1.2796 females/woman/day, respectively. Weekly multiplication of population turned into 9.1974 instances in step with week. The hypothetical female’s population in F2 technology became 2628.6129.The suggest era time (Tc) became 15.96 days recorded.
