According to the behavioral experiments with the swallowtail butterflies by Honda et al. (1986, 1988, 1990, 1992,1995), several compounds isolated from its host and non-host Rutaceae plants were identified as stimulus and inhibitory substances for their oviposition. Chlorogenic acid isolated from Zanthoxylum ailanthoides, and effect as a stimulant on P. protenor, as a inhibitor on P. memnon and no effect on P. xuthus. This compound is sepalated into 2 element, Quinic acid and Caffeic acid by hydrisis. Quinic acid is also the stimulant of P. protenor, and more, stimulant of P.memnon and P. xuthus. Electrophysiologically, the response of these butterflies to Quinic acid is not clear, on the other hand, the response of Caffeic acid which effect is not known were very clear. The effect of Caffeic acid to these butterflies should be examined.
