摘要

We have evaluated the effect of Capsicum annuum, Piper nigrum and Zingiber officinale essential oils on Anopheles gambiae adults. Volatile oils extracted from this tree plants species were evaluated toxicity on adults of An. gam biae under laboratoryconditions using WHO cones covered with volatile oils treated nets. Oils dissolved in acetone, were tested at 7.8, 3.9, 2, 1 and 0.3% (w/v). The knockdown effect 3 min after contact with the adults of An. gambiae is superior to 95% for the oils extractedfrom C. annuum and Z. officinale at concentrations of 7.8, 3.9 and 70% with the P. nigrum oil at concentration of 7.8 and 3.9%. Sixty minutes after, the knockdown effect is superior to 90% for oils extracted from C. annuum and Z. officinale at concentration of 7.8%. This effect is of 63% with the P. nigrum oil. Sixty minutes after, the knockdown effect is superior to 80% for oils extracted from C annuum and Z. officinale at concentration 3.9%. This effect is of 46% with the P. nigrum oil. Twenty four hours after, for the concentrations of 7.8 and 3.9%, the mortality rate of adults is in average 90% for the oils extracted from C. annuum and Z. officinale. This rate is in average 45% with P. nigrum oil. C annuum and Z. officinale seem to be very usefulfor the control of adults of An. gambiae.
