Disease vector control in Cuba is carried out primarily with chemical insecticides, with those based on cypermethrin being the most commonly used .In Cuba there are 30 registered formulations whose active ingredient is the cypermethrin molecule. ALPHABAN 40 WP (cypermethrin) formulation from PELGAR INTERNATIONAL LTD, UNIT 13 NEWMAN LANE, ALTON, HAMPSHIRE, GU34 2QR. UK is a high-potency wettable powder containing the potent synthetic pyrethroid. Cypermethrin is has excellent insecticidal qualities and a good knockdown effect. Before starting the field evaluation, the susceptibility status to cypermethrin was evaluated using the impregnated bottle methodology on a population of Aedes aegypti mosquitoes in the selected area, which was resistant (90% mortality). In the following study, we set ourselves the objective of evaluating the effectiveness of ALPHABAN 40 WP in Aedes aegypti control through surface bioassays and in Blattella. Germanic through residual treatment. The residual effect on different surfaces in tile, concrete and wood was evaluated with the mosquito strain collected for 10 weeks. Mortality fluctuated from the first weeks (, but remained high > 80%), on all surfaces until week 6. The highest mortality rates occurred on plastic and metal during the 10 weeks (100%). In the case of Blattella germanica, sticky traps (Insect Trap and Monitor) were used to monitor the infestation index in cockroaches, the results of which show up to a 95% reduction in the eighth week.
