A study was carried out to evaluate the potentiality of Juvenile hormone compound JHM/S-31183 against immatures of mosquitoes in natural habitats. Of two formulations tested 1% emulsifiable formulation was marginally superior than the granule formulation. Adult emergence of An. stephensi was completely inhibited upto 12 weeks when 0.5% granule formulation was applied at 0.04 ppm in wells as against 50% inhibition upto 8 weeks in pools. However, in Culex quinquefasciatus the per cent inhibition of adult emergence varied from 52 to 90 per cent. 100% inhibition in pools upto one week at 0.04 ppm in An. stephensi was also obtained with 1% emulsifiable formulation but the effect was diluted in successive weeks. The impact of this formulation was not much pronounced against Culex quinquefasciatus.
