“…showed variations in the contents of phenolic and polyphenolic compounds, highlighting a high concentration of total phenolics followed by flavonoids and flavanol, which is in agreement with the LC-MS/MS results for flavanone and kaempferol (Figure 3, Table 1). Phenolic and polyphenolic compounds make up a major group of phytochemicals in plants; flavonoids (polyphenolic substances) present a wide range of biological activities, including insecticide effects [86][87][88][89]. Flavonoids are responsible for the reduced growth of larvae and pupal survival [90], impaired feeding, digestion inhibition and the release of free radicals [91].…”

Alternative methods of insect management are an important field of study for agriculture. The current study aimed to determine the effect of aqueous extracts from Simarouba sp. (AE-S) on the biology of Plutella xylostella and to determine the toxicity of the extract to the nematode Caenorhabditis elegans (an important in vivo alternative assay system for toxicological study). Lyophilized AE-S was chemically investigated by Ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). We evaluated the effect of the botanical extract on the life cycle of P. xylostella, from larval stage to adult stage, at concentrations of 10%, 5%, 1%, 0.1%, 0.05%, and 0.01% and a control. Subsequently, we analyzed the toxicity of the extract in an in vivo model. AE-S showed high amount of phenolic and flavonoid compounds. Six compounds were identified based on UHPLC-MS/MS analysis, including flavanone, kaempferol, 4,5-dimethoxycanthin-6-one, 11-acetylamarolide, ailanthinone, and glaucarubinone. The median lethal time for P. xylostella was estimated to be 96 h in all concentrations of AE-S, and at 120 h, 100% of the individuals were dead. Larvae exposed to AE-S at concentrations of 0.01, 0.05, and 0.1% showed a reduction in leaf area consumption, underdevelopment, and reductions in movement and pupal biomass. The lowest concentrations of AE-S (0.1%, 0.05%, and 0.01%) did not cause mortality in nematodes. Thus, the aqueous extract of Simarouba sp. could be an effective control tool because it mainly acts in the larval stage, the stage at which the insect causes damage to brassicaceae.

“…Flavones and flavanols were found to be the most studied subclasses, given their higher abundance and availability in plants. In most studies, flavonoids were incorporated at a certain concentration in an insect diet, either in artificial ones [ 41 , 42 , 43 ], such as gels [ 44 , 45 ], or by application in leaf surfaces via dipping [ 46 , 47 , 48 ]. Less commonly, flavonoids were injected directly into the larvae using a syringe [ 49 , 50 ].…”

Pesticide overuse in agricultural systems has resulted in the development of pest resistance, the impoverishment of soil microbiota, water pollution, and several human health issues. Nonetheless, farmers still depend heavily on these agrochemicals for economically viable production, given the high frequency at which crops are affected by pests. Phytopathogenic insects are considered the most destructive pests on crops. Botanical pesticides have gained attention as potential biopesticides and complements to traditional pesticides, owing to their biodegradability and low toxicity. Plant-based extracts are abundant in a wide variety of bioactive compounds, such as flavonoids, a class of polyphenols that have been extensively studied for this purpose because of their involvement in plant defense responses. The present review offers a comprehensive review of current research on the potential of flavonoids as insecticides for crop protection, addressing the modes and possible mechanisms of action underlying their bioactivity. The structure–activity relationship is also discussed. It also addresses challenges associated with their application in pest and disease management and suggests alternatives to overcome these issues.

“…At the organismal level, the proven activities of hesperidin in plant-herbivore interactions include its roles as host plant recognition cue and oviposition stimulant for Papilio protenor [27,28], and in C. aurantium L. against Aphis punicae Passerini (Hemiptera: Aphididae) and Planococcus citri Risso (Hemiptera: Pseudococcidae) [29]. Hesperidin, applied as hesperidin-Mg complex, showed insecticidal activity against Spodoptera frugiperda (Lepidoptera: Noctuidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) [30,31].

Hesperidin is a highly bioactive natural flavonoid whose role in ecological interactions is poorly known. In particular, the effects of hesperidin on herbivores are rarely reported. Flavonoids have been considered as prospective biopesticides; therefore, the aim of the present study was to examine the influence of hesperidin on the host plant selection behavior of three aphid (Hemiptera: Aphididae) species: Acyrthosiphon pisum Harrris, Rhopalosiphum padi (L.), and Myzus persicae (Sulz.). The aphid host plants were treated with 0.1% and 0.5% ethanolic solutions of hesperidin. Aphid probing behavior in the no-choice experiment was monitored using electropenetrography and aphid settling on plants in the choice experiment was recorded. The results demonstrated that hesperidin can be applied as a pre-ingestive, ingestive, and post-ingestive deterrent against A. pisum, as an ingestive deterrent against R. padi, and as a post-ingestive deterrent against M. persicae using the relatively low 0.1% concentration. While in A. pisum the deterrent effects of hesperidin were manifested as early as during aphid probing in peripheral plant tissues, in M. persicae, the avoidance of plants was probably the consequence of consuming the hesperidin-containing phloem sap.
