Efficacy of fishes for control Aedes aegypti larvae

Abstract

The use of fishes to control  mosquitoes larvae is the one methods used to control dengue fever and Hemorrhagic fever instead of the temephos. This Quasi-Experimental Study was determine the efficacy of fishes each species to requires the ability to eat the Aedes aegypti larvae. The fishes were selected from the use of fish in areas where the people use in the control of mosquito larvae. We used 12 species of fishes 3 replicate at 5 day. All fishes were weighed before put into a container glass with water. We added 25 of the 3^rd or 4^th instars larvae of Aedes agypti (L.) per time. Observe if the fish eat the larvae out, then add the larvae gradually until the time 12 hours remaining larvae to scoop out the count the fish eat the larvae start experiment from time to time 06.00-18.00 PM. On average the ability of fish to eat mosquito larvae.

The results showed that Oreochromis spp.(goby), poecilia spp.(guppy), Anabus app., Betta spp. Tricopodus spp., Botia spp., Peterophyllum spp., Carassius spp., Gambusia spp., Trichopsis spp., Oxyeleotoris spp. And Danioninae spp. Can eat mosquitoes, the average 218.85, 176.15, 131.15, 120.29, 105.68, 94.60, 69.18, 65.35, 63.12, 59.33, 43.22 and 41.29 / day / weight fish 1 g., respectively. The best fish that can eat the larvae is goby and guppy, respectively.  The results showned that fish of all species have the ability to eat the mosquito larvae. Intake depends on the type of fish does not depend on size, but depending on the type of fish and the ability to eat. This study provides useful information as an alternative to the use of biological control of mosquito larvae. Therefore, the fish should be selected to suit the type of container and readily available in the area. Fish are safe to use and reduce the amount of chemicals used to make the budget for the purchase of chemicals used as well. It also slowed down the resistance of mosquitoes to the chemicals in the area.
