Larvivorous fishes in controlling mosquito breeding from draw wells

Culex quinquefasciatus have been found to breed in about 29 per cent of the wells in semi-urban area and 14 per cent of the wells in rural areas of Varanasi at one time or other. Majority of such wells are used-ones. Effectiveness of Poecillia reticulata, Esomus danrica and Trichogaster fasciatus in controlling well breeding is evaluated in the present study with successful results.
