The results showed that the 2nd instar larvae of Aedes epacticus were 2-3.5 times more susceptible to the IGR cyromazine and the pathogen Bacillus thuringiensis var. israelensis (Bti) than the 4th instars. Such a fact was highly pronounced on the basis of concentrations which to inhibit the emergence of 50 per cent of adults (IC(50)). Different levels of potentiation and additive effects reflected by the inhibition of adult formation were also obtained when the two tested compounds applied jointly against the present mosquito larvae. Apart from delayed lethal action, larval treatments with cyromazine and Bti did not affect the number of basal follicles developed in the ovaries of mosquito females that emerged from these treatments
