    Description / Table of Contents: Résumé Les pulvilli d'Empoasca fabae paraissent fournir un mécanisme convenable pour la fixation des insectes aux surfaces lisses des feuilles. En nous basant sur la structure morphologique des prétarses et sur des observations directes, nous suggérons que l'orientation primaire sur des surfaces lisses est réalisée à partir de mouvements concernant surtout les pulvilli. La surface des cultivars pubescents de soja, rendue très accidentée par la présence des trichomes, empêche une fixation normale permettant l'alimentation et la ponte. Cet obstacle explique en partie la quasi immunité des sojas pubescents et, à l'inverse, la sensibilité des sojas glabres aux attaques d'E. fabae.
    Notes: Abstract The pulvilli of the potato leafhopper, Empoasca fabae (Harris), seem to provide a suitable mechanism for the attachment of the insect to smooth leaf surfaces. Based on morphological structure of the pretarsal and direct observations, we propose that primary orientation of the leafhoppers on smooth surfaces is achieved through a series of motions involving mainly the pulvilli. The highly irregular surface produced by the trichomes of pubescent soybean cultivars impedes normal attachment for feeding or oviposition. This impediment explains in part the near immunity of pubescent soybean and the converse susceptibility of glabrous soybean plants to the potato leafhopper.
