Abstract

Males of the Triatominae, Panstrongylus megistus and Triatoma infestons, show a considerable difference concerning the time necessary for them to acquire the capacity for the first mating. P. megistus copulates from the eighth day of adult life, irrespective of whether or not it has been fed, while T. infestons copulates about 17 days after the imaginai moult and only after a blood-meal. These differences might be due to the secretory activity of T. infestons male accessory glands whose full development is reached only after two saturant blood-meals. If allatectomy is performed in male P. megistus soon after the imaginai moult, accumulation of secretion does not occur in 3 of the 4 accessory glands. Topical application of precocene II (200 μg/insect)a few days before or soon after the imaginai moult in P. megistus, halves the amount of secretion in the accessory glands.

Résumé

Les mâles des Triatomidés Panstrongylus megistus et Triatoma infestans, présentent une différence considerable en ce qui concerne le temps nécessaire à l'acquisition de la capacité pour réaliser le premier accouplement. Chez P. megistus le mâle devient apte à s'accoupler 8 jours après la mue imaginale, indépendamment de la prise de repas sanguin, tandis que le mâle de T. infestans ne s'accouple qu'après le Même jour après l'émergence, et cela sous la dependence du repas sanguin. Cette différence est due à l'activité sécrétoire des glandes accessoires dont le complet développement chez T. infestans n'a pas lieu qu'après la pise de 2 repas saturants. L'allatectomie pratiquée tout de suite apès la mue imaginale chez le mâle de P. megistus résulte en blockage de l'activité sécrétoire chez 3 des 4 glandes accessoires. L'application topique de 200 μg/insect de precocène II quelques jours avant ou tout de suite après la mue imaginale chez cette espèce, réduit considérablement l'accumulation des sécrétions dans les glandes accessoires.
