The activity of spiked pepper fruit essential oil against fall armyworm larvae

Abstract Spiked pepper ( Piper aduncum ) essential oil has the potency to develop as a botanical insecticide in controlling fall armyworm Spodoptera frugiperda ). This study aimed determine activity of spiked fruit oils against larvae. was held from November 2020 March 2021 at Insect Bioecology Laboratory, Faculty Agriculture, Andalas University, West Sumatera, Indonesia. The experiment used Completely Randomized Design (CRD), including preliminary and advanced tests. test conducted using three concentration levels (0%, 0.25%, 0.5%) consisted 4 replications. 5 control 0.05%, 0.07%, 0.11%, 0.17% 0.25%) ran with leaf-dipped method, parameters observed were larval mortality, feeding inhibition (antifeedant), development time. observation data analyzed analysis variance, if there any significant differences, it continued further Least Significant Difference (LSD) 5% level. LC 50 95 values POLO PC software. result showed that could cause inhibit activity, Fall growth. treatment best result, which lead 98.67% larvae by 91.23% growth reaching sixth instar around 3.26 days compared control. value solution 0.068% 0.151%, respectively. Overall, insecticidal
