Abstract
NeonateTribolium castaneum larvae were treated with 0.5 ppm pirimiphos methyl, 1.6×104 spores/gNosema whitei alone and 0.5 ppm+1.6×104 spores/g combined and the resulting adult mortality recorded. All treatments increased the mortality of the beetles significantly (P<0.01), though the combined dose gave a lower mortality than either the microsporidian or the insecticide alone.
Résumé
Les larves nouvelles nées deTribolium castaneum ont été traitées avec 0,5 ppm de pirimiphosméthyl, 1,6×104 spores/g deNosema whitei seule et le mélange 0,5 ppm+1,6×104 spores/g et l'on a enregistré la mortalité des adultes en résultant. Tous les traitements augmentaient la mortalité des Coléoptères d'une manière significative (P<0,01) quoique la dose combinée donnait une mortalité inférieure à celle obtenue par l'utilisation soit des micro-sporidies, soit de l'insecticide seul.
