Repellent effect DEET, permethrin and four essential oils and their compounds on Anopheles gambiae. Response of 4–7-day-old, non-blood-fed, sugar-fed, Kisumu strain of female mosquitos at two different concentrations (C1 and C2 μl/cm2 of product on chromatographic papers, refer to Table 1): a. corrected proportion escaping using Sun-Shepard’s formula (confidence interval calculated with the Wald method) by treatment concentration and b. dendrogram determined by hierarchical ascendant classification. 1) Pairwise comparison of proportion was done using Fisher’s test. Values in bold lettering were significantly different from the control with the Holm’s sequential Bonferroni correction method. *Pairwise comparison of proportion was done using Fisher’s test between one compound and the essential that it comes from. Values followed by a star were significantly different from the original essential oil with the Holm’s sequential Bonferroni correction method
