Fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), is a key pest of maize worldwide. Its damages on yield vary between 30 and 70% in the America, 11 to 100% in Africa and 32% in Ethiopia; the yield losses have been identified. In this study, we evaluated two types of bioassay and synthetic chemicals efficacy against fall armyworm during high infestation year under laboratory and field. Those five types of plant extracts, four types of synthetic chemicals, and two types of EPF were evaluated against fall armyworm. Among botanicals lantana camara, Azadirachta indica, Jatropha carcus, Candle bush, and Grewinia tenax were showed that the percent of larval mortalities were, 65%, 71%, 76%, 81% and 85% respectively after 72hrs. While the evaluated insecticides of Dursban 48%, Best 5EC, Karate 5 EC, and Bravo 5EC (80%, 83%, 90% and 93.3%) caused larval mortality of FAW after 72hrs. The efficacy evaluations of Matarhizium anisopliae and Beauveria bassiana were showed that the mortality of larvae caused 70% & 81% respectively after 72hrs. Three treatments that showed potent effect on mortality of FAW in vitro (Bravo 5EC, Beauveria bassiana and Grewinia tenax) were evaluated in the field condition in IPM strategy integrating with host resistance. The results of the IPM study showed that the combinations of CZH132150 x Bravo 5EC, CZH1270 x Beauveria bassiana, CZH1270 x Grewinia tenax, CZH132150 x Grewina tenax, CZH1261 x Bravo 5EC, and CZH1270 x Bravo 5EC treatments when evaluated on the field were highly and significantly reduced yield losses recorded, 20%, 21%, 24%, 25%, 31% and 32% respectively.
