  abstract = {{T}he biological efficacy as judged by mortality against {A}nopheles gambiae s.s. of three net samples, one white and two colored, treated with deltamethrin by conventional dipping was compared. {E}fficacy as well as chemical analysis results showed that uptake of insecticide by white net material was much higher than by colored nets. {A}fter a single wash, efficacy of colored nets was reduced significantly below 80% mortality, which is the minimum acceptable level for a field application. {T}his unexpected result could be because of either low uptake of insecticide by colored fibers or high alkalinity on the fibers, resulting from the dyeing process (reduction clearing). alpha-{C}yanopy-rethroids, such as deltamethrin, have a low stability in alkaline conditions and rapidly degrade. {P}ractical implications of this finding are of primary importance because the majority of nets currently purchased by institutional buyers for malaria prevention are colored.},
