Abstract
Fall armyworm (FAW), Spodoptera frugiperda (J E. Smith), is among the most destructive, global, polyphagous pests that attack a variety of host plants. It was documented in Egypt in 2019, according to the Food and Agriculture Organisation of the United Nations (FAO, 2019). Among the insecticides currently applied, Indoxacarb and Emamectin benzoate are significant due to their selective toxicity to Lepidopteran larvae. Field tests demonstrated Indoxacarb and Emamectin benzoate caused up to 83-100% elimination of Spodoptera frugiperda (J.E. Smith) under outbreak conditions during the two experimental seasons (2020-2021 &2021-2022) with no significant difference in performance (p = 0.2191). On the other hand, the root yield of sugar beet crop improved from 8.5 to 12.0 t/fed. and from 7.5 to 12.6 t/fed. during the two successive seasons, with the Increase in Yield after Treatment (IYAT) being 29.2% and 40.5% respectively, demonstrating clear correlations between reduced pest density and improved yield performance. These findings confirm Indoxacarb and Emamectin benzoate as effective chemical options within an integrated pest management system.
