Survivorship and Fertility Schedules of Two Epilachnine "Species" Feeding on Cucurbitaceous Plants under Laboratory Conditions (Coleoptera : Coccinellidae)

Self Cite

The oviposition patterns of seven "Epilachna ", one Afidenta and three "Henosepilachna" species from Indonesia and Japan were examined and compared with those of 10 Asian species of epilachnines previously documented. The 21 species were divided into two groups based on the patterns. The first group consisted of twelve "Henosepilachna" species and Afidenta misera, and the other one consisted of eight "Epilachna" species. The former group laid several to dozens of eggs in an erect position and in mass on the underside of host leaves. On the other hand, the oviposition pattern of the latter group was diverse. They laid eggs singly, or up to ten plus eggs together, on the leaf surface or in tendrils of host plants. Eggs were usually not erect, but flat on host leaves, or were attached to or inserted into tendrils. The possible relevance between the oviposition patterns and the abundance of epilachnine species in the field was briefly discussed.

E. pytho exhibited 1) longer immature stages, 2) longer mean length of the pre-reproductive period, 3) lesser fertility and 4) smaller r and larger T values than four pest epilachnine species, living at a wide elevational range.Key words: Coccinellidae / Epilachna pytho / phytophagous lady beetle / survivorship and fertility schedules / West SumatraIn our previous articles, we reported the survivorship and fertility schedules of five species of phytophagous lady beetles (subfamily Epilachninae) from Sumatra and Java, Indonesia (Nakamura et at., 1984 for Epitachna septima and E. pusillanima, previously treated as E. dodecastigma, cf.

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.
