Gene diversity was investigated in four taxa of tsetse flies (Diptera: Glossinidae) including Glossina morsitans, G.m. centralis, G. Swynnertoni, and G. pallidipes. Histochemical tests were performed for 35-46 isozymes. Polymorphic loci were 20% in G. morsitans, 32% in G.m. centralis, 17.6% in G. swynnertoni, and 26% in G. pallidipes. Mean heterozygosities among all loci were 6.6% in G. morsitans morsitans, 6.0% in G.m. centralis, 7.1% in G. swynnertoni, and 6.8% pallidipes. Allozyme gene diversities were considerably less than those reported for many Diptera. The low gene diversities are probably related to small effective population sizes.
对采采蝇（双翅目：舌蝇科）的四个分类单元进行了基因多样性研究，包括 morsitans 采采蝇、中央采采蝇、斯温氏采采蝇和淡足采采蝇。对 35 - 46 种同工酶进行了组织化学测试。morsitans 采采蝇的多态位点为 20%，中央采采蝇为 32%，斯温氏采采蝇为 17.6%，淡足采采蝇为 26%。所有位点的平均杂合度在 morsitans morsitans 采采蝇中为 6.6%，在中央采采蝇中为 6.0%，在斯温氏采采蝇中为 7.1%，在淡足采采蝇中为 6.8%。等位酶基因多样性远低于许多双翅目昆虫的报道。低基因多样性可能与有效种群规模较小有关。
