Abstract
The reproductive ability of gamma-irradiated Tribolium spp. (Coleoptera: Tenebrionidae) males was determined by studying their mating competitiveness when confined in various ratios with unirradiated males and females. Irradiated males of all the species studied competed favourably with unirradiated males for females. Competitiveness was significantly greater when males were irradiated soon after emergence (1-day old) than when they were older (10 days old). Infertility percentages increased as the proportion of irradiated males increased. The highest competitiveness was found in irradiated T. freemani and the lowest in T. destructor. Competitiveness also increased as the ratio of irradiated males increased.
Résumé
La capacité de reproduction chez mâles de Tribolium spp. (Coleoptera: Tenebrionidae) irradiés aux rayons gamma a été déterminée par des observations sur la compétitivité d’accouplement une fois que ces insectes sont mis en présence des mâles et femelles non irradiés, à des rapports variés. Les mâles irradiée de toutes les espèces étudiées entraient en compétition avec les mâles non irradiés pour s’accoupler avec les femelles. Cette compétitivité était significativement plus marquée chez les mâles irradiés sitôt après leur émergence (âge d’un jour), plutôt qu’à l’âge avancé (irradiation 10 jours après émergence). Le taux d’infertilité augmentait avec l’accroissement de la proportion des mâles irradiés. La plus grande compétitivité a été observée chez les mâles irradiés de T. freemani et tandis que la plus basse était enregistrée chez ceux de T. destructor. Cette compétitivité s’accroissait aussi avec l’augmentation du taux de mâles irradiés.
