Susceptibility of Ae. aegypti larvae to temephos with and without synergists.

+Significant difference.LC50: Lethal concentration at which 50% of the population is killed.RR50: Resistance ratio at LC50, calculated as the ratio between Cucuta and NO LC50.SR50: Synergism ratio at a LC50, calculated for each strain as the ratio between the LC50 of the treatment without synergist and the LC50 using each synergist.DEM (diethyl maleate); PBO (piperonyl butoxide, 5-((2-(2-butoxyethoxy) ethoxy) methyl)-6-propyl-1,3-benzodiox-ole); DEF (S,S,S-tributyl phosphorotrithioate.
