ABSTRACT:   The species Aedes aegypti is considered as the major vector of dengue fever and dengue haemorrhagic fever. Laboratory-based larvivorous study was done on laboratory reared 3rd and 4th instar Aedes larvae. Native larvivorous fish Aplocheilus panchax and Trichogaster trichopterus from Mingalarywarthit and Taungnar villages in Hpa-an Township were used for tests. The study was done from February 2014 to January 2015. A series of laboratory experiments compared larva consuming rates of both species of fish in different water volumes, in order to determine their potential as mosquito control agent in water storage containers. Laboratory results found that native larvivorous fish Aplocheilus panchax and Trichogaster trichopterus consumed significant numbers of Aedes larvae. Mean larva consuming rate of one individual, two together and three together of Trichogaster trichopterus fish in three different water volumes was found to be higher than that of Aplocheilus panchax. When comparing arvae/day/gm weight, one gram weight of Aplocheilus panchax consumed 463.04 number of 3rd and 4th instar Aedes larvae within 24 hours. It was 3.727 fold higher in consuming rate than one gram of Trichogaster trichopterus against Aedes aegypti larvae in the laboratory. Size and weight of Trichogaster trichopterus is bigger than Aplocheilus panchax. Larva consuming rates of both fish were significantly higher in the daytime than at night in all water volumes. Of the two native fish species, Aplocheilus panchax showed greater potential as a mosquito control agent against Aedes larvae in water storage containers in Hpa-an Township, Kayin State.
