A series of laboratory experiments compared predation rates of three native eastern Australian mangrove fish species (Psuedomugil signifer, Hyseleotris galii, Pseudogobius sp.) and the exotic Gambusia holbrooki on 2nd and 4th instar Aedes vigilax larvae, in order to determine their potential as mosquito control agents in mangrove forests. All four species preyed on significant numbers of both 2nd and 4th instar larvae. All showed a similar pattern of larval consumption, gorging on larvae in the first hour of each experiment, before reducing to a relatively constant background feeding rate. Gambusia holbrooki showed the highest larval consumption rates, but is unsuitable as a mosquito control agent due to it being an exotic pest species in Australia. Of the three native species, P. signifer showed the greatest potential as a mosquito control agent, having consumption rates comparable to G. holbrooki, and was the only species that did not show a significant reduction in larval consumption in the night experiments.
一系列实验室实验比较了三种澳大利亚东部本土红树林鱼类(澳洲假鳃鳉、加氏异塘鳢、伪虾虎鱼属)以及外来物种食蚊鱼对二龄和四龄尖音库蚊幼虫的捕食率,以确定它们在红树林中作为蚊虫控制媒介的潜力。所有这四个物种都捕食了大量的二龄和四龄幼虫。它们都表现出相似的幼虫摄食模式,即在每个实验的第一个小时内大量吞食幼虫,然后降至相对稳定的背景摄食率。食蚊鱼的幼虫摄食率最高,但由于它是澳大利亚的外来有害物种,因此不适合作为蚊虫控制媒介。在这三种本土物种中,澳洲假鳃鳉作为蚊虫控制媒介的潜力最大,其摄食率与食蚊鱼相当,并且是唯一在夜间实验中幼虫摄食量没有显著减少的物种。
