Mortality of five field-caught cockroach strains (WM, RG386, Ryan, CDR, and SY) and a control strain (UCR) following treatment with six insecticides. Darker boxes indicate lower mortality, and thus greater insecticide resistance. Note that insecticide resistance was found for all insecticides tested except for abamectin.
