From: Insecticide susceptibility of the sand fly leishmaniasis vector Phlebotomus argentipes in Sri Lanka
Knockdown and mortality percentages in susceptibility tests using the WHO bioassays with Phlebotomus argentipes populations from Pannala, Thalawa, Mamadala and Mirigama for different concentrations of DDT, malathion, propoxur and deltamethrin. n = 100 flies for each concentration of insecticide. The knockdown percentages are given at 1 h after exposure and the mortality percentages are given at 24 h after exposure. Error bars represent lower and upper 95% confidence limits
