Abstract

Eighteen species of cutworm moths were collected as larvae feeding at night on grapevines, Vitis sp. L. (Vitaceae), in south-central British Columbia, Canada, during April and May from 2004 to 2008. Ten species belonged to two genera, Abagrotis Smith and Euxoa Hübner. Abagrotis orbis (Grote), A. nefascia (Smith), and A. reedi Buckett accounted for over 85% of cutworms reared to adulthood. Abagrotis orbis and A. reedi were found in all locations; the former accounted for nearly 90% of larvae collected from vineyards on warm sandy soils. Abagrotis nefascia was largely restricted to cooler sites with heavier soils. For laboratory-reared A. orbis, pupal mass was highest and sex ratios were approximately equal when larvae were reared either on a pinto bean-based diet prepared with the recommended amount of water or on a commercial black cutworm diet and 50% of the recommended water. Survival to adult eclosion was significantly higher on the black cutworm diet, but because this was thicker than the pinto bean-based diet it was impractical to use. To date, A. orbis, A. nefascia, and A. reedi have been laboratory-reared continuously on artificial diet for more than six generations.

Résumé

Dix-huit espèces de vers-gris ont été récoltées en train de s’alimenter la nuit sur la vigne, Vitis sp. L. (Vitaceae), dans le centre-sud de la Colombie-Britannique en avril et mai de 2004 à 2008. Dix espèces appartiennent aux genres Abagrotis Smith ou Euxoa Hübner; Abagrotis orbis (Grote), A. nefascia (Smith) et A. reedi Buckett représentent plus de 85 % des vers-gris élevés jusqu’au stade de papillon adulte. Abagrotis orbis et A. reedi se retrouvent dans tous les sites; le premier représente presque 90 % des récoltes dans les vignobles sur les sols chauds et sablonneux. Abagrotis nefascia est en grande partie restreint aux sites plus frais à sols plus lourds. Chez les A. orbis élevés à l'état larvaire en laboratoire sur un régime à base de haricots pintos avec la quantité recommandée d'eau ou sur le régime de vers-gris noirs avec 50 % de l'eau recommandée, la masse des nymphes est maximale et les proportions des sexes sont à peu près égales. La survie jusqu’à l'éclosion de l'adulte est significativement plus élevée sur le régime de vers-gris noirs, mais l'épaisseur du régime le rend difficile à utiliser par rapport au régime à base de haricots pintos. À ce jour, A. orbis, A. nefascia et A. reedi ont été élevés en laboratoire de manière continue sur un régime artificiel pour plus de six générations.
