Spodoptera frugiperda is an invasive and a destructive insect pest of maize and other cereals in Ethiopia. Fall armyworm infestation and different management options were assessed at Jimma agricultural research field stations. Preliminary findings show that percentage of fall armyworm infestation ranged from 3.57% to 100% with average infestation of 54.73% in main growing season. Severe infestation due to fall armyworm is expected to decrease yield. To reduce its infestation, massive larvae collection, phermonal control and insecticides were used. Within a month a total of 601 fall armyworm moths were captured by a single sex pheromone trap. Per week 77 to 211 Spodoptera frugiperda was captured. In addition, handpicking is the most effective cultural practice for fall armyworm management. During assessment, earwig predator was abundantly found both during wet and dry season that could play a role in reducing the fall armyworm population as biological control agent. This study highlights the importance of using phermonal control, hand picking, early planting and biological agent can manage fall armyworm, and used as component of integrated pest management. Further studies are recommended to strengthen more the findings of the current study especially on the massive rearing of indigenous natural enemies and yield loss due to fall armyworm.
