Abstract:

The life table of Leucinodes orbonalis was prepared from daily fecundity and survival of cohort, when larvae were reared on brinjal c.v. Shyamala at a temperature 26± 10 C. Results on the survival of different stages of L.. orbonalis indicated 10% mortality in the egg stage and with 20% and 28% mortality in the larval and pupal stages, respectively. The longest duration of egg incubation was 5 days, while the larval and pupal periods were 18 days and 11 days, respectively. The number that survived from egg to adult emergence was 72 individuals. The net reproductive rate (Ro) was 136.35 with mean length generation (Tc) 38.05 days. The intrinsic rate of increase was 0.1294 females female-1day and population multiplied 2.4739 times in a week with generation time of 37.98 days on brinjal. The per cent contribution of eggs, larval, pupal and adults were 58.98, 37.65, 2.50 and 0.42, respectively at stable age distribution of L.orbonalis on brinjal. Life expectancy of L. orbonalis on brinjal for newly deposited eggs was 13.24 days. The mortality rate was comparatively high at the age of 35 to 40 days when the expectation of further life was reduced to only 1.80 days from 13.24 days in the beginning.
