冈比亚按蚊Giles sensu stricto是冈比亚按蚊的一个兄弟种，其复杂性与其在自然界中的地位密切相关。冈比亚复合体，已经通过染色体倒位多态性的程度以及最近通过分子水平的分歧来显示。用PCR技术对一个田间种群的A.来自津巴布韦北方坎延巴赞比西河谷地区的冈比亚复合体显示了三个兄弟物种的共存：A. arabiensis（90%）、A. gambiae（4%）和A.四环虫（6%）。对A.冈比亚公司材料揭示了在八个样品中两种分子形式S和M的同域存在。这是这两种分子形式在南部非洲共存的第一个记录。(C)2004年皇家热带医学和卫生学会。由爱思唯尔有限公司出版。保留所有权利。
The complexity of Anopheles gambiae Giles sensu stricto, a sibling species of the A. gambiae complex, has been shown by the extent of chromosomal inversion polymorphisms and more recently, by divergence at the molecular level. Analysis by PCR of a field population of A. gambiae complex from the Zambezi Valley area of Kanyemba, northern Zimbabwe, showed the co-existence of three sibling species: A. arabiensis (90%), A. gambiae (4%), and A. quadriannulatus (6%). Molecular characterization of the A. gambiae s.s. material revealed the sympatric presence of the two molecular forms S and M within a sample of eight. This is the first record of the co-existence of these two molecular forms in southern Africa. (C) 2004 Royal society of Tropical Medicine and Hygiene. Published by Elsevier Ltd. All rights reserved.
