%X Maize is the most important crop in Ethiopia. Yet, a number of obstacles mostly insects like armyworms, its production is minimal. The research were initiated to assess the prevalence and manage the fall armyworm using varieties and insecticides in the Dera district, Ethiopia. The assessment was conducted in four potential Kebeles. SPSS was used to evaluate data. For the experiment, a factorial arrangement with a combination of four synthetic insecticides (Dimeto 40% EC, Karate 5%, Agrolambsin supper 315, and Malathion 50%) with control and three maize varieties (BH-540, BH-546, and local) were laid out in a randomized complete block design with three replications. Data on pest, vegetative, and yield related parameters were collected and analyzed using SAS. The result showed a prevalence of 72.92%, and infestation of 30.69%. The main effects of insecticide and variety affects most of the vegetative, pest, and yield-related parameters. The harvest index, plant height, ear length, grain yield, and insecticide-variety interaction effect are all impacted. The application of Agrolambsin supper 315 to BH-546 variety resulted in the highest plant height, ear length, and grain yield; on the other hand, the main effects of insecticide application (Agrolambsin supper 315) and varieties (BH-546) demonstrated the maximum number of ears per plant, number of green leaves per plant, and biomass yield. Despite the fact that armyworms considerably impacted every variety of maize examined in this investigation, yield loss may be minimized by using BH-546 in combination with Agrolambsin supper 315 spraying.
