THE STUDIES ON CHROMOLAENA ODORATA OILS FROM THE FLOWERS AND LEAVES SHOWED TOXICITY TO MOSQUITOES,ALTHOUGH THE EXTENT OF TOXICITY VARIED FROM EACH OIL. LT50 DETERMINED FOR THE C.ODORATA FLOWER AND LEAF OILS USED ON THE LARVAE GAVE 10.6 MINUTES AND 12.0 MINUTES RESPECTIVELY.ADULT TREATMENTS ALSO GAVE THE LT50 OF 2.5 AND 4.0 MINUTES FOR THE FLOWER AND LEAF OILS RESPECTIVELY. THE CHROMOLAENA ODORATA OILS WERE EFFECTIVE AGAINST BOTH THE LARVAE AND ADULTS OF THE MOSQUITOES AND THEIR EFFECTS FOUND TO BE PERSISTENT.THE OIL EXTRACTS THEREFORE HAVE GOOD PROSPECTS OF BEING DEVELOPED AS INSECTICIDES FOR MOSQUITO CONTROL.
