Abstract

Film records of cutworms feeding on cabbage showed that in sampling and continuous feeding, the mandibles, maxillary palps, galeae, labial palps, and labrum contacted the leaf. Sampling involves palpation with the maxillary palps; this is followed by test biting, during which the galeae, labrum, and labial palps make initial contact with the plant. Test biting may be followed by continuous feeding in which all of the mouthparts contact the leaf in characteristic patterns. The actions of the mouthparts are discussed in relation to the function of their chemosensilla.

Résumé

L'utilization des pièces buccales du ver-gris moissoneur, Euxoa messoria, a été étudié. Deux types de comportement, le goûter et l'alimenttion continué, ont été filmés. Pour chaque type, les palpes maxillaires, les galéas, le labrer et les palpes labiaux montrent un comportement d'ensemble particulier par toucher la nourriture. Les actions des pièces buccales en relation du fonction de leur chimosensilles ont discuté.
