Experimental evidence indicates that native freshwater fish outperform introduced Gambusia in mosquito suppression when water temperature is below 25°C

摘要: In a series of laboratory trials, we compared the mosquito larvae predation efficacy four endemic fish species and introduced Gambusia holbrooki at different temperatures. Galaxias occidentalis truttaceus, consumed more 15 20°C were equally effective consumers as G. 25°C. Nannoperca vittata Bostokia porosa consuming 15, 20 in particular warrant further investigation control agent, not only due to their high consumption larvae, but also propensity kill, consume than other both 20°C. For this species, stomach size digestion rate do appear limit number killed. These results indicate that may be successful control.
