| dc.description | This study aimed to screen plant species from the Amazon region for the potential to be used in the integrated management of the fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). For this purpose, the efficiency of the hydroalcoholic extracts of 15 plant species from the Amazon region was evaluated. The extracts were obtained from plant leaves, bark, or vines. The efficiency of the extracts (30 mg-mL-1) was evaluated on eggs and third instar larvae of S. frugiperda. A range of reactions of the fall armyworm to the hydroalcoholic extracts was observed. The extract obtainedfrom the bark of Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. presented the highest efficiency against the eggs, whereas the extract obtained from the leaves of Bauhinia forficata Link was most efficient against the larvae. These findings are essential for the management offall armyworms because the deleterious effects in the initial stages of S. frugiperda development significantly reduce maize production. In conclusion, the extracts of C. spruceanum and B. forficata were more efficient for eggs and larvae of the fall armyworm, respectively. | |
