  • 描述: Swallowtail butterflies species show clear patterns of oviposition preference among plants in the field and in the laboratory. Oligophagous butterflies, such as Papilio troilus and P. palamedes, oviposit on a select group of lauraceaous plants. In contrast, P. glaucus, a polyphagous swallowtail butterfly, will deposit eggs in a consistent preference hierarchy on trees from several families. Oviposition preferences are maintained by the presence of oviposition stimulants and deterrents in the foliage of host and non-host plants, detected by chemoreceptors located on the front tarsi of butterflies. Polar extracts and fractions from the preferred host plants of P. troilus and P. palamedes sprayed on to various substrates have been shown to stimulate oviposition relative to the controls. However, in addition to contact chemical stimuli, other sensory cues, such as color, odor and texture may also be important in eliciting maximum oviposition. Rejection of non-host plants also has a chemical basis. P. glaucus avoid ovipositing on host leaves sprayed with polar extracts from a non-host tree species. The experimental results decisively show that phytochemical stimuli detected through tarsal chemoreceptors governs host plant selection by these swallowtail butterflies.
