| description | <p>Abstract</p> <p>Background</p> <p>The use of repellent materials from plants against nuisance insects is common with great potential to compliment existing malaria control programmes and this requires evaluation in the field. Ocimum plant species, <it>Ocimum suave </it>(Willd) and <it>O. kilimandscharicum </it>(Guerke) materials and their essential oils extracted by steam distillation were evaluated in the field and experimental huts for repellence, exophily and feeding inhibition effects against three mosquito species, <it>Anopheles arabiensis </it>(Patton), <it>An. gambiae </it>ss (Giles) and <it>Culex quinquefasciatus </it>(Say). The protective effect of essential oils from Ocimum plants were compared with N, N-diethly-3- methylbenzamide (DEET), a standard synthetic repellent. Also, the protective effect of fumigation by burning of repellent plants; <it>Ocimum suave, Ocimum kilimandscharicum</it>, <it>Azadirachta indica</it>, <it>Eucalyptus globules </it>and <it>Lantana camara </it>were tested in experimental huts and selected local houses.</p> <p>Results</p> <p>In the field, protection by Ocimum plants from mosquito bites was high and there was small variation among different mosquito species. Protection efficiency was 93.4%, 91.98% and 89.75% for <it>An. arabiensis </it>while for <it>Cx</it>. <it>quinquefaciatus </it>it was 91.30%, 88.65% and 90.50% for DEET, <it>Ocimum suave </it>and <it>O. kilimandscharicum </it>respectively. In the experimental hut, deterrence induced by burning of Ocimum and other plants ranged from 73.1.0% to 81.9% for <it>An. arabiensis </it>and 56.5% to 67.8% for <it>Cx. quinquefaciatus</it>, while feeding inhibition was 61.1% to 100% for <it>An. arabiensis </it>and 50% to 100% for <it>Cx. quinquefaciatus</it>.
