Baskaran, R.K.M., Srinivasan, T.R., Muthumeena, K., Muthulakshmi, S., & Mahadevan, N.R. 2002 Life table of Australian ladybird beetle (Cryptolaemus montrouzieri) feeding on mealybugs (Maconellicoccus hirsutus and Dactylopius tomentosus).. Indian Journal of Agricultural Sciences 72(1): 54-56.
Notes: A laboratory experiment was conducted from November 1999 to January 2000 to study the relative survival and multiplication of C. montrouzieri on mealybugs, Maconellicoccus hirsutus and Dactylopius tomentosus, under 27.8±2.2°C and 63.3±9.2% relative humidity. The innate capacity for the increase in the population of C. montrouzieri (rm) was 0.0876 and 0.0806, with finite rate of increase of 1.0942 and 1.0833 females female-1 day-1, on M. hirsutus and D. tomentosus, respectively. The population multiplied 100.65 and 57.74-fold between two successive generations. The mean time for completing a generation was 50.35 and 59.52 days on M. hirsutus and D. tomentosus, respectively. Reaching the stable age distribution, the population of C. montrouzieri eggs, grubs, pupae, and adults contributed 38.16, 45.65, 8.75, and 7.44% and 35.01, 52.24, 6.97, and 5.79% for M. hirsutus and D. tomentosus, respectively.
