Popis:	Apentacyclic triterpenoid, boehmeryl acetate, was identified as the dominant peak in gas chromatographic profiles of the periderm of susceptible sweet potato cultivars. Boehmeryl acetate, present in the methylene chloride-hexane (1:3) fraction of methylene chloride surface extracts, induced significantly ( P < 0.05) higher oviposition by female sweetpotato weevils on sweet potato cores in laboratory bioassays. Dose-response studies showed significant linear and quadratic log dose effects, with peak oviposition stimulating activity for this compound at about 0.01 potato equivalents (0.04 μ g/core). Results indicate that boehmeryl acetate is an oviposition stimulant of the sweetpotato weevil, Cylas formicarlus elegantulus (Summers).
