Nine hydroxytriazenes have been synthesized and screened for their insecticidal activity against one day old Drosophila melanogaster Meig (Fruit fly). Out of all the nine compounds screened, 3-hydroxy-3-n-propyl-1-m-chlorophenyltriazene is the most active having LC50 values 0.9847 ppm. The least active compound is 3-hydroxy -3-n-propyl-1-p-methylphenyltriazene, whose values are 16.52 ppm. In general, the LC50 values range from 3.92 to 5.52 ppm.
