We tested the hypothesis that fish indirectly control mosquitoes by repelling oviposition. Aedes taeniorhynchus oviposition in mangrove forests, natural pools, and excavated pools with different concentrations of fish was compared. Oviposition in adjacent mangrove forests was concentrated in the site with the lowest fish density. In 3 mangrove forests, egg populations from pool banks were significantly (P < 0.001) lower for pools with fish than for fishless pools, with an overall mean +/- SD of 1.6 +/- 5.7 and 20.0 +/- 34.8 eggs/sample, respectively. At one pool, egg densities increased significantly (P < 0.001) from 0.36 to 5.00 eggs/sample after drying killed fish. In excavated pools, oviposition was significantly (P < 0.001) affected by fish. These data indicate that Ae. taeniorhynchus avoids ovipositing in sites with high concentrations of fish and suggest that the response is fish-mediated. This behavior may help to explain the migratory habits and population dynamics of Ae. taeniorhynchus.
我们检验了鱼类通过驱赶产卵来间接控制蚊子的假设。比较了不同鱼类浓度的红树林、天然池塘和人工挖掘池塘中埃及伊蚊的产卵情况。相邻红树林中的产卵集中在鱼类密度最低的地点。在3片红树林中，有鱼池塘岸边的卵数量显著低于无鱼池塘（P < 0.001），总体平均±标准差分别为1.6±5.7和20.0±34.8枚卵/样本。在一个池塘中，干燥杀死鱼类后，卵密度从0.36枚/样本显著增加到5.00枚/样本（P < 0.001）。在人工挖掘池塘中，产卵受到鱼类显著影响（P < 0.001）。这些数据表明埃及伊蚊避免在鱼类浓度高的地点产卵，并表明这种反应是由鱼类介导的。这种行为可能有助于解释埃及伊蚊的迁徙习性和种群动态。
