The effect of Delonix elata (Family: Caesalpinaceae) and copepod,Mesocyclops aspericornis for the control of the dengue vector,Aedes aegypti L was tested in the laboratory.Delonix elata at 25,50,100,200 and 400 ppm caused significant mortality of A.aegypti larvae.Lethal concentrations (LC50 and LC90) were worked out.The LC50 values for I to IV larval instars were 88.669%,100.153%,116.419%,124.553% and for pupae was 107.921%,respectively.
