An insect growth regulator, S-31183, 2- [1-methyl-2- (4-phenoxyphenoxy) ethoxy] pyridine, was applied into 2 slow running streams to evaluate its efficacy against malaria vectors from the beginning of February to the end of April 1987. The evaluation of the efficacy was based on bioassay with the waters sampled from the streams and on the parity of the mosquitoes collected from the study site. The application of S-31183 induced almost 100% inhibition of emergence of Anopheles maculatus and An. minimus, 24 hr after application. The emergence was inhibited by averages of 80% in An. minimus and 56.7% in An. maculatus, in the end of the 4th week. Likewise, the nulliparous rates also decreased till the end of the 8th week.
