Abstract
Two non-destructive sexing techniques suitable for use in the field and laboratory are described, and tested with the Warren root collar weevil, Hylobius warreni Wood (Coleoptera: Curculionidae). On the second visible abdominal sternite of males is a longitudinal depression that is absent on females. In addition, setae on the last visible abdominal sternite of females are arranged longitudinally; setae on males are arranged radially. For the first character, accuracy was 90% and sex could be determined without the aid of magnification. The latter character was slightly more reliable, at 95% accuracy, but required at least 12× magnification. Résumé—Deux techniques non destructives, permettant le sexage lors d’une étude de terrain, sont décrites pour le charançon de Warren, Hylobius warreni Wood (Coleoptera : Curculionidae). Sur le 2ème sternite abdominal visible des mâles, il y a une dépression longitudinale qui est absente sur les femelles. De plus, les setae du dernier sternite abdominal visible, sont placées longitudinalement sur les femelles, tandis que les setae des mâles sont placés radialement. La fiabilité du premier caractère est de 90 % et le sexe peut être déterminé sans l’aide d’un grossissement. Le dernier caractère mentionné est légèrement plus fiable avec une exactitude de 95 % mais nécessite un grossissement.
