Table 5 Lethal concentration 50% (LD50) and 95% (LD95) of An. arabiensis larval forms exposed to WHO discriminative doses of Temephos insecticides

From: Anopheles arabiensis in Sudan: a noticeable tolerance to urban polluted larval habitats associated with resistance to Temephos

Species 95% confidence limits LD50 (lower–upper) 95% confidence limits LD95 (lower–upper) χ2 P value
An. arabiensis melanic form (M) 1.369 (1.263–1.481) 2.287 (2.053–2.653) 0.742
An. arabiensis normal form (N) 0.806 (0.612–0.941) 1.798 (1.547–2.337) 0.778
An. arabiensis in polluted habitats 1.682 (1.557–1.805) 2.785 (2.535–3.160) 0.072
