Abstract
Five- to six-day old male pupae of Ectomyelois ceratoniae Zeller were irradiated with 0, 20, 25 and 30 krad of gamma rays. When the radiated males were mated with normal females there were deleterious effects on fertility without extreme effects on mating or fecundity. Percentage of embryonated eggs and progeny per female decreased to two thirds of the control by 25 and 30 krad treatments. Productivity of the female mated with irradiated males was decreased and significant reductions in egg viability, egg hatch and larvae per female were observed in F1 generation. Similar pattern of sterility was observed in sibling crosses of F2 at the three doses.
Résumé
Les chrysalides males de Ectomyelois Ceratoniae Zeller a läge de 5–6 jours ont ete irradies avec 0,20,25 et 30 krad. L’union de maies irradies avec femelles non-rayonnees ont causes une effet nuisible sur ta fertilité sans effets extre me sur l’union ou fécondité. L’embryogénie pourcentage et les descendances par femelle ont ete deminuees pour 2/3 de contrôle (non-irradies) avec les traitements 25 et 30 krad. La productivité de la femelle conjoint avec le maie rayonne a deminue aussi let une reduction significant en viabilité d’oeuf, declore d’oeuf, et la larve par femelle a ete observe chez le F1. Une exemple semblable de la sterilite a ete observe chez le croisement parente pour les F2 par trois doseses.
