Three species of epilachnine beetles, Epilachna sp. 3 (aff. emarginata) (EM) feeding on Mikania sp. (Compositae), E. vigintioctopunctata (EV) and E. enneasticta (EN) both feeding on Solanum torvum (Solanaceae), were reared to study the survivorship and fertility schedules under laboratory conditions. Duration for the development of the immature stages, mean longevity of adults, mean length of the pre- and post-reproductive period, and total number of eggs produced per female were recorded. The demographic parameters such as the intrinsic rate of natural increase (r), reproductive value (V_x / V_o), and mean length of a generation (T) were calculated.
