Aphrodisiac pheromones of the sulfur butterfliesColias eurytheme andC. Philodice (Lepidoptera, Pieridae)

Abstract

Male wing compounds involved in maintaining reproductive isolation between the sulfur butterfliesColias eurytheme andC. philodice have been identified. MaleC. philodice produce threen-hexyl esters; myristate, palmitate, and stearate, which are absent inC. eurytheme. A branched hydrocarbon, 13-methylheptacosane, is found on the wings of maleC. eurytheme, but notC. philodice. Several straight-chain hydrocarbons are on the wings of both species. The esters and 13-methylheptacosane have significant electrophysiological activity. Preliminary behavioral experiments indicate that the esters (especiallyn-hexyl myristate) function as species-recognition signals. The esters and 13-methylheptacosane also have low-to-moderate aphrodisiac activity.
