本期的四篇系列论文探讨了五种染色体形式的An的生殖状态。冈比亚湾使用分子技术来检查位于整个An的12个不同基因之间的变异。冈比亚公司基因组这些和以前的研究结果是一致的假设，至少部分的障碍，在象牙海岸和其他西非国家的一些染色体形式之间的基因流的北部和西部，但在贝宁和东部国家之间的S和M型基因渗入。总的来说，这些研究表明，需要更广泛的地理抽样的安。gambiae s.s.，增加对合子前生殖隔离机制的研究，以及对杂种的存活和繁殖力进行实地研究，以检验合子后生殖隔离。
A series of four papers in this issue explores the reproductive status of the five chromosomal forms of An. gambiae ss. using molecular techniques to examine the variation among twelve different genes located throughout the An. gambiae s.s. genome. Results of these and previous studies are consistent with a hypothesis of at least partial barriers to gene flow between some chromosomal forms in the Ivory Coast and other West African countries to the north and west, but introgression between S and M types in Benin and countries to the east. Collectively, these studies indicate the need for a broader geographical sampling of An. gambiae s.s., increased research on mechanisms of prezygotic reproductive isolation and field-based studies of survival and fecundity in hybrids to test for postzygotic reproductive isolation.
