采采蝇占据不连续的栖息地，它们之间的基因流动需要进行调查，以预测区域范围的控制计划。用6个微卫星位点对7个稻螟Glossina morsitans submorsitansNewstead种群进行了遗传多样性分析，用5个微卫星位点对6个稻螟Glossina morsitans submorsitansNewstead种群进行了遗传多样性分析。M. MorsitansWestwood populations. Nei's无偏方差为0.808，G. M. submorsitans和G. M. Morsitans。在三种实验室培养物中，腹泻较少。种群内的交配是随机的。种群在遗传上高度分化。种群被强烈细分，固定指数（FST）为0.18 inG。M. Morsitans和0.17 inG. M.亚摩西坦人35%的遗传变异在G. M. submorsitans归因于冈比亚和埃塞俄比亚人群之间的差异。所有现有的遗传学证据表明，遗传漂变比基因流动大得多。莫尔西坦斯有限公司
Tsetse flies occupy discontinuous habitats and gene flow among them needs to be investigated in anticipation of area‐wide control programs. Genetic diversities were estimated at six microsatellite loci in sevenGlossina morsitans submorsitansNewstead (Diptera: Glossinidae) populations and five microsatellite loci in sixG. m. morsitansWestwood populations. Nei's unbiased diversities were 0.808 and 76 alleles inG. m. submorsitansand 0.727 and 55 alleles inG. m. morsitans. Diversities were less in three laboratory cultures. Matings were random within populations. Populations were highly differentiated genetically. Populations were strongly subdivided, as indicated by fixation indices (FST) of 0.18 inG. m. morsitansand 0.17 inG. m. submorsitans. 35% of the genetic variance inG. m. submorsitanswas attributed to differences between populations from The Gambia and Ethiopia. All available genetic evidence suggests that genetic drift is much greater than gene flow amongG. morsitans s.l.populations.
