Antiherbivore effect of Cuscuta campestris against Spodoptera frugiperda

Nutritional Indices and Efficacy of Acokanthera spectabilis (Hochst.) Extract and Chlorfluazuron against Spodoptera littoralis (Boisd.) Escorted by Mitigating Amendment to the Light Impact

“…These data met previous investigations that may have interpreted the decline in nutritional indices, like sesquiterpenoids, neophytadiene (Saber et al, 2018) exhibited antifeedant activity, whereas phylloquinones, and phytol (Anderson et al, 1993) had deterrent effects against the 4 th instar larvae of S. littoralis. Likewise, the saturated fatty acid, palmitic acid attained antifeedant activity against S. frugiperda (J. S. Smith) (Sung et al, 2023). Additionally, some HPLC phyto-compounds of A. spectabilis extract, like gallic (Punia et al, 2021), ellagic, and caffeic acid (Rani and Pratyusha, 2013;Punia et al, 2020;Punia et al, 2023) were potent compounds that significantly reduced RGR, RCR, ECI, ECD, and AD in the survival larvae of S. litura (F.).…”

“…Syringic, and ferulic acids in extracts of different cotton varieties resulted in complete mortality during the first week of treatment in Helicoverpa armigera (Hübner) (Perveen et al, 2001;Punia et al, 2023). Moreover, the presence of GC-MS free carboxylic fatty acids and their derivatives that have been detected in A. spectabilis extract, such as oleic, octadecanoic, ç-linolenic, palmitic, 9,12octadecadienoic acid and, hexadecanoic methyl ester possessed double bonds in their chains that may be proportionally correlated with their insecticidal activity against the larvae of S. littoralis (Khamis et al, 2016;Eldesouky et al, 2019;Abdullah, 2019;Sung et al, 2023). In addition, diterpene compounds, and neophytadiene may be confirmed by the study of Saber et al, (2018) for their promising insecticidal activity and synergistic effects against S. littoralis larvae.…”

“…Neophytadiene, quercetin, and double bond-free carboxylic or methylated fatty acids could realize larvacidal effect against S. littoralis (Boisd.) (Mesbah et al, 2007;Khamis et al, 2016;Saber et al, 2018;Eldesouky et al, 2019;Abdullah, 2019;Sung et al, 2023). On the other hand, several field experiments of chlorfluazuron showed a conspicuous growth inhibition in the early instars larvae and reduction population of many lepidoptrous pests, (Wang et al, 2021;Zhou et al, 2023;Eldessouky and Korish, 2023).…”
