Abstract: Mosquitoes are amongst the anthropophagic insects because they feed on human blood and have medical importance to human as pest and vectors of some most distressing diseases. Mosquitoes borne disease currently represent greater health problems in tropical and subtropical climate and no part of world is immune to this risk. Aedes mosquitoes are best known vector of yellow fever and dengue fever. Different growth regulators are used for the control of mosquitoes. These effect the life span of different growth stages. So, the present study was carried out to evaluate the effect of insect growth regulator (pyriproxifen and altosid) on the life span of different growth stages. Three different dosage pattern of pyriproxifen and altosid Pro-G low dose, under dose, high dose will be used under lab conditions. Five serial concentrations (66, 6.6, 0.66, 0.066 and 0.0066) were used and the mortality data were taken after 24, 48 and 72 hr. Larvae were placed in 250 ml pyrex glass beaker with 200 ml distilled water and respective insecticide concentration. The present research concluded that pyriproxyfen and altosid is an effective in controlling immature population. The altosid was found the best as compared to pyriproxifen in retarding larval population that increased larval duration and time to complete the life span. In this respect the fecundity of the Aedes population was also suppressed appreciably.
