The action biocida of Bacillus thuringiensis SH-14 var. Israelensis (Bti) in front of the larvas of Aedes aegypti, it has been investigated starting from their discovery, however their residual activity and the high production cost and formulation has been until today one of the disadvantages for which its application has not been completely successful. In this context, the present investigation had for objective to evaluate the residualidad of three formulations of Bacillus thuringiensis Sh - 14 var. Israelensis cultivated in "sanguaza" on the percentage of mortality in larvas of A. aegypti, for such an effect three formulations of Bti were elaborated with biopolímeros; flour of lived corn, carragenina and their combination to 0.5 and 2% of active ingredient (i.a.), being exposed the larvas of third stadium A. aegypti to 0.1g of each formulation, the mortality of larvas registered by means of direct observation at the 48 hours of having applied the treatments, then they were carefully removed with a plastic pipette, later on a new lot of 25 larvas of A. aegypti was introduced in the containers at the 1, 10, 20, 30, 40, 50 and 60 days post application of the formulations. The results show the increase of the residualidad from Bti when formulating it in flour of corn lived to 2% of i.a. producing a LT/50 until the 28 days postaplicación, also the formulation Bti - carragenina to 2 ia%, the minimum residualidad that is expressed in a LT/50 after 2 days of having applied the treatment took place. On the other hand, the formulation Bti - lived corn - carragenina achievement a LT/50 until the 18 days postratamiento. Therefore the formulation Bti - corn lived to 2% of i.a is with more residualidad, possibly due to the effect fotoprotector of the antocianinas contained in the biopolímero.
