Se evaluó la resistencia de Haematobia irritans (Diptera: Muscidae) del ganado bovino por exposición a dosis letal (DL50 y DL99) a los insecticidas Cipermetrina (Piretroide) y Coumafos (Organofosforado) en ranchos de Tierra Caliente del estado de Guerrero, México. Se utilizaron 30 ranchos, colectando de cada uno, 240 moscas de la superficie corporal de los bovinos. Sub-muestras de 20 moscas en triplicado fueron desafiadas a las formulas por la técnica de papel filtro impregnado a dosis concentradas de 2,5; 6,0 y 0 μg/cm2 de Cipermetrina y de 0,01; 0,06 y 0 μg/cm2 de Coumafos durante dos horas. La resistencia de H. irritans a Cipermetrina y Coumafos fue del 100% en los ranchos evaluados, debido a que la mortalidad de moscas promedio fue baja...
