## Abstract The repellent activity of essential oils of lemon eucalyptus (__Eucalyptus maculata citrodion__), rue (__Ruta chalepensis__), oleoresin of pyrethrum (__Chrysanthemum cinerariaefolium__) and neem (__Azadiracta indica__) have been field tested as 40%, 50% and 75% solutions in coconut oil against populations of mosquitoes consisting mainly of __Mansonia__ in Gambella, western Ethiopia. A latin square design was used to randomize the test subjects for possible individual differences for mosquito attraction. Repellency was evaluated as the percentage protection. Deet was included in the study for comparison. All the plant products manifested repellency. At 50% concentration at which the highest repellency was recorded the protection was 91.6%, 87.0%, 96.0%, 97.9% for rue, neem, pyrethrum and deet, respectively. The essential oil of lemon eucalyptus was not tried at this concentration. At a 40% concentration deet, lemon eucalyptus and pyrethrum were significantly (__p__ < 0.05) more effective than rue and neem. At a 50% concentration, deet and pyrethrum were significantly better (__p__ < 0.05) than rue and neem. At a 75% concentration concentration, deet and lemon eucalypus p
