COMPARATIVE EFFICACY OF PYRETHROIDS ON Aedes aegypti, Aedes albopictus AND Culex quinquefasciatus COLLECTED FROM DIFFERENT ECOLOGICAL ZONES OF PUNJAB, PAKISTAN

Abstract

Chemical control is widely adopted method in mosquito control that emphasizes on the management of the adult and larval populations using various insecticides. Present study was carried out in the year 2015 to use chemicals which were currently being utilized in mosquito control program against prevalent mosquito species (Culex and Aedes spp.) collected from different ecological zones of Punjab (Pakistan) (i.e. Faisalabad, Lahore and Rawalpindi) formed as a result of dengue prevalence to evaluate their efficacy by performing adult bioassay using standard WHO protocols. Results revealed that among three pyrethroids used as adulticides, alpha-cypermethrin 10% SC showed greater residual efficacy and percent mortality on various substrates/surfaces like cement, mud, plaster, wood and filter paper followed by lambda-cyhalothrin 10% CS and deltamethrin 5WP in a period of 20 weeks. Response of these chemicals was greater on filter paper and cement and less on wood and mud. Data collected on these parameters was subjected to SPSS and Minitab software for drawing inferences.
