d-(+)-Pinitol, an oviposition stimulant for the pipevine swallowtail butterfly,Battus philenor

Abstract
Oviposition by females of the pipevine swallowtail butterfly,Battus philenor, was stimulated by contact with alcoholic extracts of host foliage.d-(+)-Pinitol was isolated and identified from leaf material of one host species,Aristolochia macrophylla (Aristolochiaceae). In combination with chloroform-soluble components of host leaf material, this compound was comparable to the parent extract in stimulating oviposition.
