Repellent activity of Piper guineense
and Xylopia aethiopica
fruits oils in liquid paraffin were evaluated against adult Aedes aegypti
in the laboratory. Results showed that repellency is dependent on both the concentration and time after application. P. guineense
and X. aethiopica
oils showed complete protection from mosquito bite for 2h at 35%(v/v) and 30% respectively. The activity of eucalyptus oil (positive control), a commercial repellent, at 30% was only able to protect for 2h. Both oils used could be applied as repellents where protection from mosquito bite is sought for, over a short period of time.
