El presente trabajo tiene por objeto actulizar el inventario de insectos plaga prensentes en los cultivos de guanábana en la provincia del Guayas donde se recorrieron las fincas y se tomaron muestras de insectos en la etapa de floración – fructificación que afectan directa o indirectamente la producción. El estudio de las muestras se hizo en el laboratorio de AGROCALIDAD donde se procedió luego a la clasificación taxonómica de las especies consideradas como plaga. Se obtuvo un total de 17 tipos de insectos en la cual predominan los Hemípteros con una presencia mayor de las familias Aphididae, Coccidae y Pseudociccidae. También se encontraron las plagas conocidas como primarias Cerconota anonella y Bephrateloides maculicollis.
