From 1980 to 1985, the zoological park of Brazzaville was the only tsetse resting site located in downtown which supplied others temporary sites. The last trapping survey carried out in this area in 1987 showed that there were no more tsetse flies. Knowing that areas free of tsetse used to be reinvaded many years later, we have carried out an entomological survey in the area with the aim to verify what has happened more than twenty years later; given that suitable environmental conditions for Glossina are still available.
Sixteen pyramidal traps were set out at the edge of the forest, along paths and around animal's cages and were examined twice a day, at 10 a.m. and 4 p.m. during four days.
No tsetse fly was captured. Using the formula previously described; the probability of capturing a tsetse fly is 0.002.
The zoological park seems close to be free of tsetse flies. Long-lasting surveys within the town and around are required before stating a complete disappearance of tsetse in the town.
1980年至1985年期间，布拉柴维尔动物园是位于市中心的唯一采采蝇栖息场所，它为其他临时场所提供采采蝇。1987年在该地区进行的最后一次诱捕调查显示，已不再有采采蝇。鉴于过去没有采采蝇的地区多年后曾再次受到侵扰，我们在该地区开展了一项昆虫学调查，目的是核实二十多年后发生了什么情况；因为仍然存在适合舌蝇生存的环境条件。
在森林边缘、沿路径以及动物笼子周围设置了16个金字塔形诱捕器，在四天时间里，每天上午10点和下午4点对其进行两次检查。
未捕获到采采蝇。使用先前描述的公式，捕获采采蝇的概率为0.002。
动物园似乎即将没有采采蝇。在宣布该市采采蝇完全消失之前，需要在市内及周边进行长期调查。
