Abstract

In traditional practice, oregano leaves are crushed or shredded, and are scattered in the area to be protected from mosquitoes. The effectiveness of this method was tested using a set up based on the high throughput screening system utilized by the WHO in their guidelines for the efficacy testing of spatial repellents. Trials were done with a variation in the length of exposure to the active ingredient. In the 5 minute exposure experiment, 60% of the trial showed no response to Oregano, while 40% showed an attractant activity. In the 20 minute trials, both showed repellent activity.
