The larvicidal effect of secondary metabolites Verticillum lecanii,Pencillium chrysogenum and Aspergillus niger against filaria vector Cx.quinquefasciatus was investigated. efficacies have been tested at four different concentrations mentioned fungi (25,50,75,100)ppm .larvicidal efficacy demonstrates that larval mortality related to concentration, exposure time age. Higher observed high moreove...

A study was undertaken to correlate the impact of housing and patterns of house construction on the vector density and transmission of filaria among the inhabitants of these houses. Three different types of houses in ecologically similar hamlets of Hariharpur village in Varanasi were selected for determining the density of Culex quinquefasciatus, the vector of Wuchereria bancrofti and its infec...
