Abstract

An oviposition stimulant for the cerambycid beetle, Monochamus alternatus,from an aqueous acetone extract of inner bark of Pinus densiflora, was identified as a flavanonol glucoside, (-)-2,3-trans-dihydroquercetin-3'-O-beta-D-glucopyranoside. Two dimeric proanthocyanidins, along with polymeric proanthocyanidins, were also isolated from the extract and identified as procyanidins B-l [epicatechin-(4 beta--> 8')-catechin] and B-3 [catechin-(4 alpha--> 8')-catechin]. In the presence of a fraction of the extract, a mixtureof the polymers and either B-1 or B-3 stimulated oviposition of the femalebeetle. However, the glucoside, B-1, B-3 and the polymers were inactive alone.
