1.塞内加尔河流域发现了冈比亚按蚊复合体的三种兄弟蚊子：冈比亚按蚊。melas Theobald，An. gambiae Giles和安氏隐翅虫An.阿拉伯藜2.一个. MELAS仅限于河流三角洲和海水繁殖地附近。3.一个. gambiae和An. arabiensis是同域分布在研究区; arabiensis在沿海地区占主导地位，在那里它也在旱季繁殖;冈比亚主要分布在内陆地区，繁殖主要限于雨季（7月至9月）。4.一个.结果表明，在整个研究区域内，拟南芥的染色体具有多态性，倒位频率变化很大，尤其是2 Ra排列。5.一个. gambiae的特征在于非常高频率的2 Rb-2La倒位排列，这是草原染色体形式的典型。
1. Three sibling species of mosquitoes of the Anopheles gambiae complex are found in the Senegal River Basin: An. melas Theobald, An. gambiae Giles and An. arabiensis Patton. 2. An. melas is restricted to the river delta and environs where saltwater breeding places are present. 3. An. gambiae and An. arabiensis are sympatric in the study area; An. arabiensis predominates in coastal zones where it breeds also during the dry season; An. gambiae predominates in inland areas where breeding is mostly restricted to the rainy season (July-September). 4. An. arabiensis is chromosomally polymorphic all over the study area, with much variation of inversion frequencies, particularly for the 2Ra arrangement. 5. An. gambiae is characterized by a very high frequency of the 2Rb-2La inversion arrangement which is typical of the Savanna chromosomal form.
