To assess the presence of the potential dengue vector Aedes mediovittatus relative to other mosquito species, data were examined from 44,199 larvitraps operating between January 1984 and December 1987 in the town of Mariel, Cuba. Of 1,068 larvitraps containing mosquitoes, 626 (58.6%) were positive for Ae. mediovittatus. Its relative presence increased each year except 1986, going from 37.9% of the positive traps in 1984 to 70.2% in 1987. More larvitraps were positive for Ae. mediovittatus than for Culex quinquefasciatus, which typically dominated breeding sites at the end of the intensive phase of the national campaign against Ae. aegypti in the early 1980s. The results appear to reflect Ae. mediovittatus' gradual infiltration into areas covered by the campaign, a factor that may need to be considered in efforts to control dengue in the Americas.
为评估潜在的登革热媒介中带伊蚊相对于其他蚊种的存在情况，对1984年1月至1987年12月期间在古巴马里埃尔镇运行的44199个幼虫诱捕器的数据进行了检查。在1068个装有蚊子的幼虫诱捕器中，626个（58.6%）中带伊蚊呈阳性。除1986年外，其相对存在率逐年增加，从1984年阳性诱捕器的37.9%增至1987年的70.2%。中带伊蚊呈阳性的幼虫诱捕器比致倦库蚊更多，致倦库蚊在20世纪80年代初全国抗击埃及伊蚊强化阶段结束时通常在繁殖地占主导地位。结果似乎反映了中带伊蚊逐渐渗入该运动覆盖的地区，这一因素在美洲控制登革热的努力中可能需要加以考虑。
