Table 2 Overall percentage mortality response of both Anopheles gambiae ss and Culex quinquefasciatus exposed in different concentrations (ppm) of S.terebinthifolia in both laboratory and semi field environments for 72 hours

From: Insecticidal activity of the essential oil from fruits and seeds of Schinus terebinthifolia Raddi against African malaria vectors
