Characterization of the Terpene-Inducing Factor Isolated from the Larvae of the Sweet Potato Weevil, Cylas formicarius FABRICICUS (Coleoptera: Brenthidae)

Abstract

Terpene phytoalexins such as ipomeamarone are produced in sweet potato roots by infestation with the sweet potato weevil, Cylas formicarius. We indicated that the terpene-inducing factor of the weevil larvae included at least three components, namely glycoprotein component(s) adsorbed by Con A-Sepharose, Con A-Sepharose non-adsorbed protein components(s) and heat-stable low molecular weight component(s). © 1981, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
