本文报道了安氏按蚊染色体近着丝粒倒位的多态性。funestus多线染色体进行了研究，沿着样带在塞内加尔，以评估其在空间和时间水平上的变化。从西部到东南部，染色体多态性程度有所增加。在地理水平上，倒位频率的变化是非常显着的，无论染色体臂考虑。然而，在染色体倒位频率的变化并没有显着改变，无论是季节或年份，除了倒位3b在迪尔莫村。这样的地理变异在一个相对有限的区域内，与时间的稳定性，建议有限的基因流之间的人口研究，可能是由于在一个不连续性。Funestus的分布及其生物生态学。
The polymorphism of paracentric inversions of An. funestus polytene chromosomes was studied along a transect in Senegal in order to assess their variations at the spatial and temporal level. There was an increase in the degree of chromosomal polymorphism from the West to South-East. At the geographical level the variations in inversion frequencies were highly significant whatever the chromosomal arm considered. However, the variations in the chromosomal inversion frequencies did not change significantly over either seasons or years, except for inversion 3b in the village of Dielmo. Such geographical variability within a relatively limited area, associated to temporal stability, suggest a restricted gene flow between the populations studied, probably due to discontinuities in the An. Funestus distribution and to its bioecology.
