Present study was carried out to determine the larvivorous activity of fishes was found in Lower Manair Dam to identify the potential fish species for consuming larval forms. The listed 58 larvivorous potential fish species were collected and identified in the laboratory based on the morphometric and meristimatic characters. Pelagic feeders occupy 25.59%, bentho pelagic feeders occupy 24.14%, d...

BACKGROUND Adult female Anopheles mosquitoes can transmit Plasmodium parasites that cause malaria. Some fish species eat mosquito larvae and pupae. In disease control policy documents, the World Health Organization (WHO) includes biological control of malaria vectors by stocking ponds, rivers, and water collections near where people live with larvivorous fish to reduce Plasmodium parasite trans...

1Ministry of Health and Labour, Hargeisa, Somalia. ABSTRACT An intervention study was conducted on the introduction of the larvivorous fish Oreochromis spilurus spilurus as a method of malaria vector control in Kalabeydh village, northern Somalia. This species is resistant to chlorine in water up to a concentration of 1.0 mg/L. Fish were introduced into 25 berkit (reservoirs). After 1 month the...

There is growing of the effects of insecticide used controlling the vectors of human diseases. Manipulating or introducing an auto-reproducing predator into the ecosystem may provide sustained biological control of pest populations. The selection of a biological agent should be based on its self-replicating capacity, preference for the target pest population in the presence of alternate natural...

BACKGROUND & OBJECTIVES Indigenous larvivorous fishes bear potential for regulating vector mosquitoes through trophic interactions. The mosquito prey preference of five indigenous larvivorous fishes in the presence of alternative food items was assessed to highlight their use in mosquito vector management. METHODS Laboratory experiments were carried out using the larvivorous fishes Ambassis (...

of dams and network of irrigation canals have received considerable attention in the past and health impact assessments of such projects have also been conducted1, 2. Large-scale construction activities often bring about considerable ecological changes and create new mosquito breeding habitats. Moreover, increased supply of water may bring about an overall behavioural change in the community le...

background: the widespread use of chemical insecticides, resistance in vectors and environmental problems, all have led to an increased interest in the use of biological agents in malaria control programs. the most important functional elements are the native fish. the aim of this study was to identify the native species of lavivorous fish in rudan county, southern iran, to introduce an effecti...

Mosquito control with the use of insecticides is faced with the challenges of insecticide resistance in disease vectors, community refusal, their high cost, operational difficulties, and environmental concern. In view of this, integrated vector control strategies with the use of larvivorous fishes such as Guppy (Poecilia reticulata) and Gambusia (G. affinis) as biological control agents were us...

workers (Aitken, 1901; Alcock, 1902; Fry, 1912; Hora, 1927; Graves, 1930; Prashad and Hora, 1936; Covell, 1927 and 1941) confirmed the utility of larvivorous fish in India. The Top Minnow extensively used in Italy, South America and West Indies, and imported into India about 1929 from Italy and Siam, has established its reputation as a valuable larvicide. Three imported and twentytwo indigenous...
