A field experiment on effect of population density of lac insect Kerria lacca Kerr. on its growth and survival was conducted on Cajanus cajan, with seven treatments replicated thrice, during the year 2018-19. Lac insect population of 40, 50, 60, 80, 100, natural population per 2.5cm2 as well as no insect were the seven treatments the highest survival of lac insect from brood lac inoculation to harvest was 81.53 percent in the population density of 40 insects per 2.5cm2. Highest of male insects was 6.67 per 2.5cm2 in the natural population settlement of 127.39 lac insects per 2.5cm2, while least 1.39 was in 60 lac insects per 2.5cm2. Male emergence was observed between 129th and 143rd day after brood lac inoculation.
