我们研究了在冈比亚河的洪泛区使用本地鱼类调节蚊子的潜力，冈比亚农村地区蚊子的主要来源。从2005年5月至2007年11月，沿沿着两条2.3公里长的断面，从河漫滩向陆地的边缘到河流，对鱼类和蚊子幼虫进行了采样。采用半野外试验方法，研究了鱼类对蚊幼虫的捕食能力以及鱼类化学信号对产卵的影响。在野外，在最常见的河漫滩鱼类几内亚罗非鱼存在的地方，发现库蚊幼虫的机会较小;然而，按蚊的存在与任何鱼类的存在或不存在无关。在半田间试验中，T. guineensis和Epiplatys spilargyreius是有效的捕食者，在1 d内清除所有的后期库蚊和按蚊幼虫。在有鱼的地方产卵的库蚊较少，表明产卵的库蚊雌性避开有鱼的水。相反，产卵按蚊是不受鱼类。我们的研究表明T.几内亚蚊是冈比亚控制蚊子的潜在候选者。
We examined the potential of using native fish species in regulating mosquitoes in the floodplain of the Gambia River, the major source of mosquitoes in rural parts of The Gambia. Fishes and mosquito larvae were sampled along two 2.3-km-long transects, from the landward edge of the floodplain to the river from May to November 2005 to 2007. A semifield trial was used to test the predatory capacity of fish on mosquito larvae and the influence of fish chemical cues on oviposition. In the field, there was less chance of finding culicine larvae where Tilapia guineensis, the most common floodplain fish, were present; however, the presence of anophelines was not related to the presence or absence of any fish species. In semifield trials, both T. guineensis and Epiplatys spilargyreius were effective predators, removing all late-stage culicine and anopheline larvae within 1 d. Fewer culicines oviposited in sites with fish, suggesting that ovipositing culicine females avoid water with fish. In contrast, oviposition by anophelines was unaffected by fish. Our studies show that T. guineensis is a potential candidate for controlling mosquitoes in The Gambia.
