Abstract
Pyemotes parviscolyti Cross & Moser is phoretic only onPityophthorus bisulcatus Eichhoff; it attacks all stages of this insect except the adult. Females, which contain little or no venom, prey on other scolytids if galleries overlap. Males copulate with females ofPyemotes ventricosus Newport and vice versa, but only males of the mother species result. Copulation withPyemotes scolyti Oudemans was not successful.
Résumé
Pyemctes parviscolyti Cross & Moser est phorétique seulement surPityophthorus bisulcatus Eichhoff; il attaque tous les stades de cet insecte à l'exception de l'imago. Les femelles, qui possèdent peu ou pas de venin, s'alimentent aux dépens d'autres scolytides si les galeries se recoupent. Les mâles s'accouplent avec les femelles dePyemotes? ventricosus Newport et réciproquement. La copulation avecPyemotes scolyti Oudemans n'a pas de succès.
