“…Both apigenin and genistein are known for their anti-herbivore properties. Apigenin is highly toxic to larvae of southern house mosquito Culex quinquefasciatus Say (Diptera: Culicidae), affects the fecundity, mortality, and food consumption of Formosan termite Coptotermes formosanus Shiraki (Blattodea: Isoptera: Rhinotermitidae), shows antifeedant activity against striped flea beetles Phyllotreta striolata (Coleoptera: Chrysomelidae) 59 – 61 . Apigenin reduced the pea aphid abundance and phloem sap ingestion on alfalfa, caused a reduction in the number and duration of probes when added to saponin mixtures in artificial diets, and was accumulated in vegetative parts of aphid-infested pea plants 62 .…”

To reveal the antixenosis potential against the pea aphid Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae) we analyzed the pea aphid survival and probing behavior, and the quantitative and qualitative variation of flavonoids in the leaves of selected soybean Glycine max (L.) Merr (Fabaceae) cultivars ‘Aldana’, ‘Annushka’, ‘Augusta’, ‘Madlen’, ‘Mavka’, ‘Simona’, ‘Violetta’, and ‘Viorica’. Aphid survival was drastically impeded on all cultivars. The electronic monitoring of aphid probing using the Electrical Penetration Graph (EPG) technique revealed that on all soybean cultivars, A. pisum readily probed into leaf tissues but the probes were usually terminated before reaching vascular tissues, which demonstrates the activity of antixenosis mechanisms in peripheral tissues epidermis and/or mesophyll in soybean leaves. The potency of antixenosis factors differed among soybean cultivars, which was reflected in differences in aphid survival and frequency and duration of phloem sap ingestion. Seven flavonoids were found: apigenin, daidzein, genistein, glycitein, isorhamnetin, kaempferol, and rutin, which occurred in different amount and proportion in individual cultivars. The content of apigenin and genistein in all soybean cultivars studied probably made them relatively unacceptable to A. pisum. Kaempferol in ‘Aldana’ might be responsible for the observed strong antixenosis resistance of this cultivar to A. pisum. The results of our survey provide the first detailed data that can be used for future studies.

“…We identified a diverse array of plant metabolites that could accurately distinguish between the two groups of Eadya (Figure 5D, Table S3). Among top contributing compounds to axes 1 & 2, we identified two general groups of compounds: (1) fatty acid derivatives (Docosanoic acid, phenylmethyl ester (C106), 4H-1-Benzopyran-4-one, 5-hydroxy-7-methoxy-2-(4-methoxyphenyl)-6,8-dimethyl-(C105), and Octadecanoic acid, 2,3-dihydroxypropyl ester) and ( 2) compounds with known larvicide activity (agarospirol, ascaridole epoxide, alpha-pinene, alpha-phellandrene, phytol, and eucalyptol) (de Castro et al, 2016;Johnson & Singh, 2017;Kaczmarek, Wrońska, Kazek, & Boguś, 2020;Mohamed & Jong, 2014) Docosanoic acid has the potential to function as either a kairomone or synomone in both insects and plants. Docosanoic acid is a derivative ofEucalyptus cuticular wax, a known Coleopteran attractant, and changes in Docosanoic acid correspond with larval maturation in certain insects (Courtney, Lassak, & Speirs, 1983;Gosney et al, 2016;Kaczmarek et al, 2020;Sarkar & Barik, 2015).…”

The order Hymenoptera is one of, if not the most, species-rich order of animals, primarily driven by the many parasitoid wasps and their unique arthropod hosts. As hosts are necessary for survival, host location and selection have direct fitness implications. Semiochemicals, also known as infochemicals, from either the host herbivore or the plant are just one of many cues that parasitoid wasps use to locate a suitable host. The reliability-detectability hypothesis suggests that infochemicals from the host herbivore are the most reliable indicators of host presence. However, as localized signals, infochemicals are less detectable by parasitoids. Alternatively, infochemicals from plants are detectible over longer distances, although these signals are less reliable indicators of host herbivore presence. In this study, we explore the occurrence of infochemicals emitted by plants and their association with parasitoid host selection. We identified 112 phytochemical compounds extracted from Eucalyptus leaves that had been attacked by leaf beetle herbivores (Chrysomelidae) which had in turn been parasitized by Eadya larval-parasitoid wasps (Braconidae). Using several phylogenetic and statistical approaches, we conclude that host selection in two species of Eadya wasps is heavily influenced by infochemicals from the plant 1st trophic level. With this evidence, we propose amending the reliability-detectability hypothesis to include direct interaction between the 1st and 3rd trophic levels in a scenario where an oligophagous parasitoid utilizes oligophagous hosts.
