Table 2

Knock-down times (KDT) and mortality rates of Anopheles mosquitoes after exposure to diagnostic concentrations of 0.1% bendiocarb and 0.25% pirimiphos-methyl for 60 minutes.

Study site	Insecticide	Total exposed	No. of replicates	No. dead	KDT50 (min) 95% CI	KDT95 (%) 95% CI
Nsinze Parish	0.1% Bendiocarb	100	5	98	6.6 (4.8–8.2)	21.6 (18.9–26.1)
Nawaikona Parish	0.1% Bendiocarb	100	5	100	2.8 (0.9–4.9)	36.0 (28.3–53.9)
Nsinze Parish	0.25% Pirimiphos-methyl	100	5	40	81.4 (69.6–189.1)	118.9 (87.4–660.7)
Nawaikona Parish	0.25% Pirimiphos-methyl	100	5	9	62.9 (59.9–67.9)	88.5 (78.7–109.3)

CI, confidence interval; KDT, knock-down time; KDT₅₀, time taken for 50% of test mosquitoes to be knocked down; KDT₉₅, time taken for 95% of the test mosquitoes to be knocked down.
