Fig. 4From: Clothianidin-resistant Anopheles gambiae adult mosquitoes from Yaoundé, Cameroon, display reduced susceptibility to SumiShield® 50WG, a neonicotinoid formulation for indoor residual sprayingKnockdown values after 1 h exposure to 150 µg/ml of clothianidin in bottle bioassays. Knockdowns were compared between Anopheles and Culex species (A) and between field populations of An. gambiae (B). Standard errors of the mean are shown as vertical bars. * p < 0.05 (Fisher’s exact test)Back to article page
