| Resumo: |
The effect of aqueous extracts of Talisia esculenta (T.E.) and Sapindus saponaria (S.S.), were evaluated on the development and mortality of 8-14th day-life Spodoptera frugiperda, an important pest of maize. Corn leaves were dipped in the aqueous extracts (1% w/v) and offered as food to the caterpillars. The treated corn leaves with the extracts caused larval mortality (26.71%/T.E.; 63.3%/S.S.) and also showed effect on the larval weight (237.50 mg/T.E.; 86.65 mg/S.S.) when compared with the control (11.3% and 293.45 mg), mortality and larval weight, respectively. The electrophoresis with gelatin (0.1%) showed two very clear white areas (trypsin activity) in the caterpillars midgut of all the treatments. Only the caterpillar treated with S. saponaria presented significant differences, showing trypsin activity (10.59%). Sapindus saponaria appeared better than Talisia esculenta and showed good potential to be used as control agent for S. frugiperda.
