采采蝇Glossina morsitans morsitans Westwood和G.在津巴布韦赞比西河流域的Rekomitjie研究站和卡里巴湖的雷德克利夫岛上，在出现后12小时内标记并释放了pallidipes Austen。对重新捕获的苍蝇和野生收集的样本进行卵巢解剖。在Rekomitjie >90%的雌性G. M. Morsitans在4日龄时授精，G. pallidipes 7天。对于这两个物种在两个网站的最大的卵母细胞的长度，在卵巢类别零苍蝇，大约线性增加的前6天，并在c排卵。6-8天最大的卵母细胞在以后的周期中生长明显更慢。对于嗜热脂肪地芽孢杆菌M. morsitans，而G. pallidipes，率随温度升高;率总是高于在实验室中观察到的。在Rekomitjie，对于这两个物种，在22摄氏度的平均屏幕温度下，第一个幼虫在c. 18日龄和随后的幼虫以11天的间隔;间隔随着温度的升高而缩短。0.5天/摄氏度。在雷德克利夫岛上，两个物种的间隔比在Rekomitjie在任何给定的屏幕温度下短2天，有时短至7天。幼虫在子宫内的长度在怀孕期间呈指数增长。
Tsetse flies Glossina morsitans morsitans Westwood and G. pallidipes Austen were marked and released within 12h of emergence at Rekomitjie Research Station, Zambezi Valley, Zimbabwe, and on Redcliff Island, Lake Kariba. Ovarian dissections were performed on recaptured flies and on wild collected samples. At Rekomitjie >90% of female G. m. morsitans were inseminated by age 4 days and G. pallidipes by 7 days. For both species at both sites the length of the largest oocyte, for flies in ovarian category zero, increased approximately linearly for about the first 6 days and was ovulated at c. 6-8 days. The largest oocyte grew significantly more slowly in later cycles. For G. m. morsitans, but not for G. pallidipes, the rate increased with temperature; the rates were always higher than observed in the laboratory. At Rekomitjie, for both species and at a mean screen temperature of 22 degrees C, the first larva was produced at c. 18 days and subsequent larvae at 11-day intervals; the intervals decreased with temperature by c. 0.5 days/degrees C. On Redcliff Island the intervals for both species were 2 days shorter than at Rekomitjie at any given screen temperature and were sometimes as short as 7 days. The length of the larva in utero increased exponentially during pregnancy.
