Larvicidal Effect of Secondary Metabolites of Three Fungi against Cx.quinquefasciatus (Diptera:Culicidae)
Abstract
The larvicidal effect of secondary metabolites of Verticillum
lecanii,Pencillium chrysogenum and Aspergillus niger against filaria vector
Cx.quinquefasciatus was investigated. efficacies have been tested at four different
concentrations of secondary metabolites of mentioned fungi (25,50,75,100)ppm
.larvicidal efficacy demonstrates that larval mortality was related to concentration,
exposure time and larval age. Higher mortality was observed at high concentration,
moreover mortality increased when exposure time increased , additionally , the
older larvae were more resistant to fungal filtrate. Also, it was perceptible that
larvae of Cx.quinquefasciatus have a chieved higher mortality for V.lecanii, at the
concentration (100ppm )after 24 ,48,and 72 hrs for first instars were....
