An autogenous species belonging to the Aedes (Stegomyia) scutellaris subgroup was found on the island of Tafahi, Kingdom of Tonga. A subcolony was established at Johns Hopkins University, Baltimore, Md., USA, where cross-breeding experiments were conducted with the Samoan strain of A. polynesiensis. The cross between Tafahi females and A. polynesiensis males produced viable hybrid progeny, which were inbred through five generations. The reciprocal cross was not successful. F(1) Tafahi x A. polynesiensis hybrid males were backcrossed successfully to Tafahi females, but of the many eggs produced by backcrossing these F(1)TP males to A. polynesiensis females, only 0.7% hatched. Of the eggs produced by the F(2)TP male x A. polynesiensis female backcross, about 7% were viable. The results indicate a close genetic relationship between the Tafahi species and A. polynesiensis. The one-directional compatibility observed suggests the existence of cytoplasmic factors for sterility, which might eventually be useful in the control of members of the A. scutellaris complex.
在汤加王国的塔法希岛上发现了一种属于埃及伊蚊（白纹伊蚊亚属）的本地物种。在美国马里兰州巴尔的摩的约翰·霍普金斯大学建立了一个亚群体，在那里用波利尼西亚伊蚊的萨摩亚品系进行了杂交实验。塔法希雌蚊与波利尼西亚伊蚊雄蚊杂交产生了可存活的杂交后代，并进行了五代近亲繁殖。反交未成功。F(1)塔法希×波利尼西亚伊蚊杂交雄蚊成功地与塔法希雌蚊回交，但将这些F(1)TP雄蚊与波利尼西亚伊蚊雌蚊回交所产的许多卵中，只有0.7%孵化。F(2)TP雄蚊×波利尼西亚伊蚊雌蚊回交所产的卵中，约7%是可存活的。结果表明塔法希物种与波利尼西亚伊蚊之间存在密切的遗传关系。观察到的单向兼容性表明存在不育的细胞质因子，这最终可能有助于控制埃及伊蚊复合体的成员。
