Table 1 Times and knockdown ratios of Anopheles gambiae (s.l.) samples from Limbe, Tiko and Buea to insecticide susceptibility tests

From: Insecticide susceptibility status of Anopheles gambiae (s.l.) in South-West Cameroon four years after long-lasting insecticidal net mass distribution

Study site Insecticides tested n KDT50 (min) (95% CI) KDT95 (min) Rtkd50 Status
Limbe Deltamethrin (0.05%) 119 29.8 (28.4–31.1) > 60 3.1 Resistant
Permethrin (0.75%) 78 > 60 > 60 un Resistant
Tiko Deltamethrin (0.05%) 84 46.2 (44.0–48.8) > 60 4.9 Resistant
Permethrin (0.75%) 78 > 60 > 60 un Resistant
Buea Deltamethrin (0.05%) 147 36.5 (34.9–38.2) > 60 3.8 Resistant
Permethrin (0.75%) 88 > 60 > 60 un Resistant
