Abstract

The fall armyworm (Spodoptera frugiperda) is one of the main pests in corn (Zea mays L.). It reduces production by primarily damaging the leaves, stems, and fruits of corn, causing economic losses. Corn damage worldwide due to the fall armyworm is estimated to be at least $2,481 to $6,187 million. The insecticidal activity of five essential oils (rosemary, ginger, neem, lavender, and clove) on the 3^rd instar stage of the fall armyworm was evaluated. The insecticidal activities of deltamethrin and five essential oils were evaluated using the immersion method. Rosemary and ginger essential oils showed the highest larval mortality (100% of fall armyworm larvae were killed) at a 1:500 dilution rate, whereas rosemary, ginger, neem, and clove essential oils, except lavender essential oil, showed 96% mortality at a 1:100 dilution rate. Using GC/MS analysis, the main compounds of rosemary essential oil were determined as 1,8-cineole (22.27%), a-pinene (15.01%), camphor (12.19%), b-pinene (8.11%), D-limonene (6.10%), and a-terpineol (4.97%). The results of this study suggest that rosemary and ginger essential oils could be used as potential biological control agents for controlling the fall armyworm.
