EVALUATION OF NIFA BIO-LARVICIDE IN NATURAL HABITATS OF Culex quinquefasciatus UNDER FIELD CONDITIONS AT DISTRICT MARDAN

Mosquitoes transmit severe diseases in human beings, causing millions of deaths every year due to dengue fever. Indiscriminate use of synthetic chemicals in indoor and outdoor of mosquitoes breeding sites has caused physiological resistance and adverse environmental effects in addition to high operational cost. But due to environmental constraints, health hazards and resistance development in mosquitoes, other environment friendly vector control strategies are important. Previous researchers have been reported the bio pesticides as useful for the control of mosquitoes larvae. NIFA bio-larvicide was applied in selected breeding habitats of Aedes aegypti and Culex quinquefasciatus under the field conditions and reductions in the densities of 3rd and 4th instars larvae were compared with that of untreated matched as controls. Three different concentrations were used as 25, 50 and 100ppm. The present work discusses the potential of this product as potential larvicides for the control of mosquitoes. The results showed that an application of the formulation at the rate of 125ppm provided 19.67% reduction followed by 50 and 100 ppm as 94 and 98 % of larvae in different selected breeding sites on day 1; thereafter 100% reduction was recorded at after 4 and 5 days in all the tested concentrations. This product was found effective in suppressing mosquito larval population in different breeding sites under natural field conditions.
