Shyamala at a temperature 26 10 C. Results on the survival of different stages of L. orbonalis indicated 10 mortality in the Leucinodes egg stage and with 20 and 28 mortality in the larval and pupal stages respectively. The orbonalis longest duration of egg incubation was 5 days while the larval and pupal periods were 18 Life table days and 11 days respectively. The number that survived from egg to adult emergence Brinjal. was 72 individuals. The net reproductive rate Ro was with mean length generation Tc days. The intrinsic rate of increase was females female-1day Article Info and population multiplied times in a week with generation time of days on Accepted brinjal. The per cent contribution of eggs larval pupal and adults were 24 January 2017 and respectively at stable age distribution of on brinjal. Life expectancy Available Online of L. orbonalis on brinjal for newly deposited eggs was days. The mortality rate was 10 February 2017 comparatively high at the age of 35 to 40 days when the expectation of further life was reduced to only days from days in the beginning. Introduction Brinjal Solanum melongena shoot and fruit trend. The study of life table of an insect borer Leucinodes .
