Twenty three samples of Aedes aegypti populations from the islands of Tahiti and Moorea (French Polynesia) were tested for their oral susceptibility to dengue type 2 virus. The high infection rates obtained suggest that the artificial feeding protocol used was more efficient than those previously described. Statistical analysis of the results allowed us to define two distinct geographic areas on Tahiti with respect to the susceptibility of Ae. aegypti: the east coast, with homogeneous infection rates, and the west coast, with heterogeneous infection rates. No geographic differences could be demonstrated on Moorea. The possible mechanisms of this phenomenon are discussed in connection with recent findings on the variability of susceptibility of Ae. aegypti to insecticides.
对来自塔希提岛和莫雷阿岛（法属波利尼西亚）的23份埃及伊蚊种群样本进行了登革2型病毒口服易感性测试。所获得的高感染率表明，所采用的人工喂食方案比先前描述的方案更有效。对结果的统计分析使我们能够根据埃及伊蚊的易感性在塔希提岛上定义两个不同的地理区域：东海岸感染率均匀，西海岸感染率不均一。在莫雷阿岛上未发现地理差异。结合最近关于埃及伊蚊对杀虫剂易感性变异性的研究结果，讨论了这一现象的可能机制。
