Abstract

The purpose of this study was to determine the effect of yam seed extract (P. erosus) on the feeding activity and attack intensity of armyworms (S. litura) on mustard leaves (B. juncea) and also to workout effective concentration against feeding activity and attack intensity (S. litura). This quantitative study used an experimental method with a completely randomized design with 11 treatments and 4 replications, so 44 experimental units were obtained consisting of P0 to P10. Based on the ANOVA test, the results showed that the Fvalue was greater than Ftable which means that yam seed extract had a significant effect on the feeding activity and attack intensity of S. litura. Further, the concentration of 5% (P10) was most effective in reducing the feeding activity and attack intensity of S. litura. Thus, yam seed extract has a potential and is expected to be used as an environmentally friendly plant-based insecticide.
