Abstract

The suitability of four indigenous species (Descurainia pinnata (Walt.) Britt., D. richardsonii (Sweet) O.E. Schulz, Lepidium densiflorum Schrad., and Rorippa palustris (L.) Besser) and one introduced species (Erysimum cheiranthoides L.) of Cruciferae as host plants for the larvae of the red turnip beetle, Entomoscelis americana Brown, was tested in the laboratory using excised true leaves as food and Brassica napus L. and D. sophia (L.) Webb as control treatments. R. palustris was a suitable food plant. D. pinnata, D. richardsonii, E. cheiranthoides, and L. densiflorum were marginally suitable. Of the four indigenous species, R. palustris probably is the only one that normally is a host plant of the larvae in nature.

Résumé

On a mené des essais en laboratoire afin de déterminer si quatre crucifère indigènes (Descurainia pinnata (Walt.) Britt., D. richardsonii (Sweet) O.E. Schulz, Lepidium densiflorum Schrad. et Rorippa palustris (L.) Besser) ainsi qu'une espèce introduite (Erysimum cheiranthoides L.) étaient des plantes hôtes appropriées pour la chrysomèle du navet, Entomoscelis americana Brown, en utilisant comme aliment les premières feuilles fraîchement coupées de ces plantes, et Brassica napus L. et D. sophia (L.) Webb comme traitements témoins. R. palustris est une plante adéquate, tandis que D. pinnata, D. richardsonii, E. cheiranthoides et L. densiflorum conviennent à la limite. Des quatres espèces indigènes, R. palustris est probablement la seule qui soit normalement une plante hôte des larves en nature.
