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 / Vo)' and mean length of a generation (T) were calculated.Key Words: Epilachna / Coccinellidae / West Java / Indonesia / Survivorship and fertility schedulesIn the preceding papers, we reported the demographic traits of three epilachnine beetles obtained in Padang, Sumatra under laboratory conditions. The beetles, Epilachna septima Dieke and E. dodecastigma Wiedemann, both feeding on cucurbitaceous plants showed more prolonged longevity and fertility schedules than temperate species, including Japanese epilachnine beetles. These species are obviously well adapted for living in tropical environment like Padang (Nakamura et at., 1984;Abbas et at., 1985;Inoue et at., 1993). The present article will describe the reproductive schedules of three epilachnine species, Epilachna sp. 3 (aff. emarginata Dieke; see ; thereafter abbreviated as EM), E. vigintioctopunctata Fabricius (EV) and E. enneasticta Mulsant (EN), which were collected in Bogor, West Java, under laboratory conditions, and compare them with the previous results obtained in Padang, Sumatra.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
