The thermonebulization efficcacy of the insecticide propoxur used in Aedes aegypti control was evaluated by means of tests carried out in S. José do Rio Preto, S. Paulo, Brazil. Comparative studies monitored by caged mosquitoes - Culex quinquefasciatus - indicated that the applications of the insecticide influenced mosquito mortality greatly, this did not exceed 43% when application were performed between 5 p.m. and 5.30 p.m., but for applications carried out after 7 p.m. the mortality mean was 73%. In tests performed at night it was observed that mean mortality was not inferior to 95% in the cages situated in presences with doors and windows open and in those in which the doors and windows were closed a mean mortality not higher than 13% was observed. Mosquito mortality did not differ significantly when the concentration of the insecticide was increased from 1:12 to 1:9.
