“…Henagamage et al [54] reported that ethyl acetate extracts of Tagetes erecta L. (Asteraceae) and Datura metel L. (Solanaceae) induced anti-feeding activity against S. frugiperda at 0.2, 0.4, and 0.6 µg µL −1 in the quantification of phytochemicals. It was observed that, among the most abundant compounds in the extract of T. erecta, phenols and flavonoids ranked highest (at 107 mg g −1 and 128 mg g −1 , respectively); meanwhile, in the extract of D. metel, 89.4 mg g −1 of phenols was found, while 83.7 mg g −1 of flavonoids was found.…”

Spodoptera frugiperda is the main pest of maize. One of the alternatives proposed for its control is the implementation of products of botanical origin, such as those derived from Ricinus communis. In this work, the insecticidal and insectistatic activities of methanolic and hydrolyzed methanolic extracts of the aerial parts of R. communis and kaempferol against S. frugiperda are evaluated. The methanolic extract presented a larval mortality rate of 55% and an accumulated mortality rate of 65% starting at 4000 ppm, with LC50 values of 3503 (larvae) and 2851 (accumulated); meanwhile, from a concentration of 1000 ppm, a decrease in pupa weight at 24 h of 20.5 mg was observed when compared to the control. The hydrolyzed methanolic extract presented a larval mortality and accumulated mortality rate of 60% from a concentration of 1000 ppm, and a decrease in pupa weight at 24 h of 35.31 mg was observed, when compared to the control. For the compound kaempferol 3-β-D-glucopyranoside, a larval mortality rate of 65% and an accumulated mortality rate of 80% were observed from 800 ppm, with LC50 values of 525.2 (larvae) and 335.6 ppm (accumulated); meanwhile, at 300 ppm, a decrease in pupa weight of 25.59 mg after 24 h was observed when compared to the control.

“…Te terpene compounds in these EOs inhibit larval and pupae developmental stages [19,25,26]. Indeed, certain phytopesticides already have shown larvicidal, ovicidal, antifeedant, and repellence activities against S. frugiperda [25,[29][30][31].…”

Plant-derived insecticides, such as essential oils, can be an effective alternative to replace synthetic chemical insecticides against Spodoptera frugiperda, which becomes increasingly resistant to synthetic products. This study aims to evaluate essential oils (EOs) effects on larval growth and development following feeding inhibition, growth regulation, and repellency of EOs of Lippia multiflora (Verbenaceae), Cymbopogon schoenanthus (Poaceae), and their combination. Topical application of EOs was used on S. frugiperda larvae for larvicidal effect or treating filter paper with the EOs to find repellency. The effect of EOs on food intake and larval growth was also evaluated. Several types of compounds have been identified in the EOs, mainly monoterpenes with the appearance of new compounds in the 1 : 1 combination. Bioassay results show that individuals and combinations of EOs significantly influenced S. frugiperda larval development. L. multiflora caused 100% mortality of L2 larvae within 24 hours at 3%. The Lm + Cs (1 : 1) EOs combination was the most effective with LC50 and LC90 of 1.02% and 1.92%, respectively. Lm + Cs (1/4 : 3/4) EOs caused the highest inhibition of food consumption, 0.0160 g consumed after food was treated with 2.2% concentration compared to food consumption of 0.0602 g for the control group at 24 hours. Lower food consumption caused the inhibition of larval growth and weight loss of 0.0005 g/day at the 2.2% EOs concentration. The highest repellency effect of the EOs was found in EOs of L. multiflora, exhibiting a repulsion of 83.33% of the larvae after 3 hours of exposure. This diversity in the biological actions of the EOs tested on S. frugiperda represents valuable options for contributing to integrated pest management and an alternative to synthetic chemical insecticides.

“…It would be very beneficial to develop novel natural insecticides from some undiscovered plant species, such as insecticidals, ovicidals, antifeedants, and ovipositional deterrents, as an effective substitute for synthetic pesticides. The action of plant-derived compounds on pest insects is exerted in many ways, such as an as an antifeedant [1]; a larvicidal [9]; an ovicidal [10]; oviposition deterrent activity [10]; and a repellent [11].…”

Different organic solvent extracts of Cymodocea serrulata leaves exhibited antifeedant activity against Spodoptera litura larvae. Maximum antifeedant activity (88.95%) was observed in ethyl acetate extract at a 5 percent concentration. Five fractions were isolated from ethyl acetate extract by column chromatography and tested individually at four different concentrations, viz., 125, 250, 500, and 1000 ppm, for antifeedant activity. Among the five fractions, fraction I showed promising antifeedant activity (91.12%) at a 1000 ppm concentration. Deformities in larvae, pupae, and adults were also recorded. The preliminary phytochemical analysis showed the presence of alkaloids, terpenoids, flavonoids, tannins, phenolic compounds, glycosides, and steroids.
