Observation on Attraction to Plants Using Y-Tube Olfactometer of Female Adults of the Black Vine Weevil (Otiorhychus sulcatus (Fabricius)) (Coleoptera: Curculionidae)

Abstract

Attraction to food plants of female adults of the black vine weevil, Otiorhychus sulcatus (Fabricius), was observed by Y-tube olfactometer. Significantly more adult weevils were attracted to carrot roots (Daucus carota L. sativus Hoffm), leaves of grape (Vitis labrusca L.) and polygonum (Polygonum longisetum L.) than to the blank of water. They were not, however, similarly attracted to the leaves of strawberries (Fragaria×ananassa Duchesne), roses (Rose sp.), tomatoes (Lycopersicon esculentum Mill.), or plantain (Plantago asiatica L.), nor to 1 mg of cis-3-hexenol.
