In 1992 a survey on the use of deltamethrin-impregnated mosquito nets was conducted in the municipality of Costa Marques, Rondonia. In the intradomicile, impregnated nets decreased the vector density at rates similar to those for non-impregnated nets during low-transmission periods; during high anopheline density periods, they led to a significant reduction in vector density, while in the non-impregnated net group there was an increase in the number of anophelines captured. There was no change in vector density in the peridomicile. In the impregnated net group, the most frequently captured species was Anopheles darlingi (63.2%), found mostly in the peridomicile, while Anopheles deaneorum (35.3%) was most frequent indoors. The impregnated mosquito nets' excitatory-repellent effect decreased the intradomiciliary vector density but did not alter density in the peridomicile.
