Abstract

The effect of fly age, sex, and period of starvation on the uptake and development of Trypanosoma congolense infection was examined in Glossina morsitans morsitans. In a study consisting of 1739 specimens of various ages, young unfed 16-hr-old flies and 2-day-old starved flies developed significantly higher mature infections than 2-day-old and 7-day-old flies which had been fed previously on a clean blood meal. Females displayed significantly higher immature infections, while mature infections were recorded more frequently in males, suggesting that females possess a stronger barrier to trypanosome development. The possible factors involved are discussed.

Résumé

L'effet de läge, du sexe et de la durée de carence alimentaire chez la mouche tsétsé sur la capture et le développement de l'infection a Trypanosoma congolense a été examine chez Glossina morsitans morsitans. Dans une étude portant sur 1739 specimens de divers âges, de jeunes mouches non alimentées vieilles de 16 heures et de mouches carenćees alimentairement vieilles de 2 jours développent significativement des infections hautement matures que des mouches vieilles de 2 jours et de 7 jours qui ont été nourries préalablement sur un repas sanguin propre. Les femelles developpent des infections hautement immatures alors que des infections matures etaient observées plus fréquemment chez les males suggerant que les femelles possedent une resistance plus forte au developpement de trypanosome. On examine ici les facteurs pertinents.
