SUMMARY The effect of different inseticides on the aphid Myzus persicae was tested. Tobbaco variety Sumatra was cultivated at "Agro Comercial Fumageira SA." near Cruz das Almas BA. The experiment was realized in December (1991) and February (1992). The inseticides Acefate 750 SP, Pirimicarb 500 WP and Metamidofos 600 CE were more efficient in both times.
