Cytogenetic studies on mosquitoes collected inside bednets near Bissau City confirmed the presence of Anopheles melas Theobald and An. gambiae Giles sensu stricto, the latter species prevailing in rainy season samples (approximately 80% in average) and the former in dry season samples (> 90%). Seasonal and ecogeographical variations in the frequency of species and chromosomal inversions were analyzed. The analysis of An. gambiae sensu stricto confirmed the existence of the Bissau chromosomal form. The deficiency of heterokaryotypes in most samples indicated the possible coexistence of another chromosomal form not completely panmictic (i.e., randomly mating) with the Bissau form.
对比绍市附近蚊帐内采集的蚊子进行的细胞遗传学研究证实存在西非疟蚊（Theobald疟蚊）和冈比亚疟蚊（严格意义上的Giles疟蚊），后一个物种在雨季样本中占主导（平均约80%），而前一个物种在旱季样本中占主导（>90%）。分析了物种和染色体倒位频率的季节性和生态地理变化。对严格意义上的冈比亚疟蚊的分析证实了比绍染色体型的存在。大多数样本中异核型的缺乏表明可能存在另一种与比绍型不完全随机交配的染色体型。
