Abstract
Eggs (1,2 and 3-day-old), larvae (early and late) and 4-day-old pupae of the rice moth, Corcyra cephalonica (Stainton), were treated with 60Co gamma-radiation at doses from 0 to 100 krads. Evaluation of moth radiosensitivity by the survival of treated eggs, larvae and pupae led to the following sequence of stages in order of increasing radioresistance: for the eggs, 1, 2 and 3-day-old; for larvae and pupae, early larvae (5 days after hatching), late larvae (5 days before pupation) and 4-day-old pupae. Twenty five kiloradians was found to be the most likely unit for disinfestation by radiation of C. cephalonica.
Résumé
Les oeufs (âgés de 1, 2 et 3 jours), les larves (jeunes et vieilles) et les nymphes (âgés de 4 jours) dur ver de riz corcyra cephalonica (Stainton) étaient soummis à une radiation de 60 à des doses de 0 à 100 krads. L’évaluation de la sensibilité radiologique du ver par la survivance des oeufs, larves et nymphes traités a conduit à la séquence suivante par ordre croissant de résistance aux radiations; pour les oeufs, âgés de 1, 2 et 3 jours; pour les larves et les nymphes, jeunes larves, (5 jours après eclosión), vieilles larves (5 jours avant de devenir des nymphes), et des nymphes âgées de 4 jours, on a trouvé que 25 krad était la valeur la plus probable pour la désinfestation de C. cephalonica par radiation.
