Abstract
Oviposition preference of the butterfly Graphium agamemnon (Lepidoptera: Papilionidae) on four host plants species, Annona muricata L., Polyalthia longifolia L., Cananga odorata (Lam) Hook.f. & Thomson and Michelia alba L, were observed on 15 females and 10 males in field cage measuring 4 × 6 × 6 m. The females of G. agamemnon butterfly deposited its eggs on three species of host plants but no egg deposition on C. odorata. The number of eggs laid per plant on A. muricata was significantly higher (p < 0.05) than those on P. longifolia and M. alba. However, no oviposition preference was detected between on P. longifolia and M. alba host plants. The age-specific life table analysis was conducted on the more-preferred host plants on oviposition preference test, A. muricata. During the immature stages, the mortality (qx) of the egg stage G. agamemnon was higher than in the other stages. Furthermore, the fifth instar larvae had the highest mortality (qx) in the larval stage. Predators were the most important factor of mortality in immature stages of G. agamemnon and. The spiders family of Salticidae and Oxyopidae prey in all of the larval instars, meanwhile family of Thomisidae preferred in the young larvae.
