Abstract

The egg follicle C of the left ovary was developing first, indicating reversed ovarian sequences in 5.8, 4.8, 4.2, 2.2, 1.1 and 2.0% newly-emerged female G. pallidipes from pupae kept at 29.5 ± 0.5, 27.5 ± 1.0, 25.0 ± 0.5, 22.5 ± 0.5, 20.5 ± 1.0°C and then maintained at ambient temperature (19 to 31°C) in the local colony. There was a highly significant positive correlation between the frequency of reversed ovarian sequences in flies and temperature in the range 19.5–30.0°C. The incidence of the abnormality was very low (0.2%) in wild-caught females from the Lambwe Valley, probably reflecting the constancy of favourable temperatures in that location. Old females with altered ovarian sequence had apparently both normal pregnancy and alternate maturation of eggs between the ovaries. This appears to be the first report suggestive of a temperature-induced reversed sequential ovarian development in Glossina.

Résumé

Le follicule C de l'ovaire 1gauche de la mouche tsé-tsé Glossina pallidipes est le premier à se développer, indiquant ainsi un développement séquentiel anormal dans 5,8, 4,8 4,2, 2,2, 1,1 et 2,0% de femelles émergeant des pupes maintenues à 29,5 ± 0,5, 27,5 ± 1,0, 22,5 ± 0,5, 20,5 ± 1,0°C et puis à la température ambiante (19 à 31°C à l'insectarium). Une corrélation significativement positive entre la fréquence de développement ovarien anormal chez les insectes et les températures de 19,5 à 30,0°C a été observée. La fréquence d'anomalies chez les femelles capturées à Lambwe Valley était très basse (0,2%), reflétant sans doute la stabilité des températures favorables dans cette localité. Les femelles agées ayant un développement ovarien séquentiel anormal ont à la fois une gestation normale et une maturation alternée entre les deux ovaires. Il est ainsi démontré pour la première fois que la température induit un développement ovarien séquentiel anormal chez Glossina.
