Table 1 Resistance ratio of wild Anopheles coluzzii populations from non-agricultural (Vitre) and agricultural areas (Tiassale and Gagnoa) exposed to three neonicotinoids

From: Evidence of insecticide resistance selection in wild Anopheles coluzzii mosquitoes due to agricultural pesticide use

Localities Insecticides KDT50 (95% CI) in minutes Resistance ratio*
Kisumu Wild strains
Vitre Acetamiprid 13.7 (10.47–16.68) 15.52 (13.6–18.013) 1.130
Imidachloprid 18.2 (14.95–21.88) 104.6 (77.2–197.7) 5.747
Tiassale Acetamiprid 13.7 (10.47–16.68) 20.9 (14.14–25.7) 1.526
Imidachloprid 18.2 (14.95–21.88) 111.6 (78.3–247.4) 6.132
Gagnoa Acetamiprid 13.7 (10.47–16.68) 15.7 (11.6–19.07) 1.062
Imidachloprid 18.2 (14.95–21.88) 1 knock down only after 1 h +++
  1. KDT50: The time necessary to allow 50% of test mosquito populations to be knocked down. Determined using the PoloPlus software 1.0 via log-probit analysis
  2. *Resistance ratio (RR) calculated as the KDT50 of the wild strain divided by the KDT50 of the susceptible Kisumu strain
  3. +++ could not be calculated, indefinite
