    Description / Table of Contents: Résumé Des pontes de la Teigne des ruches,Galleria mellonella, infectées expérimentalement avec des conidies deAspergillus flavus ont été rapidement recouvertes de mycélium et furent éventuellement détruites. Les tubes germinatifs issus des conidies ont pénétré non seulement les œufs infertiles mais aussi les œufs blessés. Les œufs sains furent souvent pénétrés à la fois par des tubes germinatifs conidiens et des éléments mycéliens. Une fois pénétrés, les œufs se remplissent de mycélium en moins de 2 jours, après lesquels le mycélium et les conidiophores ressortent à l'extérieur à travers le chorion.
    Notes: Abstract Egg masses of the greater wax moth,Galleria mellonella L. experimentally infected with conidia ofAspergillus flavus Link became rapidly covered with the mycelium and were eventually destroyed. Germ tubes from conidia penetrated not only infertile, but also damaged eggs. Healthy eggs were often penetrated both by conidial germ tubes and mycelia elements. Once penetrated, eggs become filled with mycelium in as little as two days, after which conidiophores and mycelia protrude outwardly through the chorion.

    Description / Table of Contents: Résumé Des observations ont été effectuées sur l’histopathologie du termite souterrain des régions orientales,Reticulitermes flavipes (Kollar) infecté par le champignonBeauveria bassiana (Balsamo) Vuill. Les symptômes initiaux des termites infectés sont l’inertie, l’excrétion anale, la passivité et l’absence de réponse aux stimuli tactiles. Les ouvriers infectés du 5e stade passent de la couleur crème normale au brun clair. La pénétration du tégument par les tubes germinatifs deB. bassiana commence dès 16 heures après l’inoculation. L’infection par le tube digestif est également obtenue. Après la pénétration à travers le tégument, le champignon attaque le corps adipeux, puis le tissu nerveux et finalement la musculature.
    Notes: Abstract Observations were made on the histopathology of the eastern subterranean termite,Reticulitermes flavipes (Kollar) infected with the fungusBeauveria bassiana (Balsamo) Vuill. Initial symptoms of infected termites were sluggishness, anal discharge, passivity, and failure to respond to tactile stimuli. Infected fifth instar worker termites changed from a healthy creamy color to a light brown. Penetration of the integument by germ tubes ofB. bassiana occurred as early as 16 hours after inoculation. Infection through the digestive tract also resulted. Following penetration of the integument the fungus attacked the fat body, then the nervous tissue and finally the musculature.
