This study aimed at evaluating the influence of greenleaf desmodium (Desmodium intortum (Mill.) Urb. (Fabaceae) infochemicals on the behaviour of three select parasitoids of kale pests (aphids and Diamondback moth), to determine the potential of enhancing the protection of vegetables in integrated push-pull cropping systems. To achieve this, the volatile-mediated behavioural responses of the parasitoids towards D. intortum volatiles were evaluated using a dual-choice Y-tube olfactometer. Our results showed that Cotesia vestalis (Hymenoptera: Braconidae), a parasitic wasp for Diamondback moth (DBM) (Plutella xylostella (Linneaus)) was not attracted to volatiles from D. intortum compared to DCM and empty oven bag controls. Nevertheless, D. intortum VOCs elicited higher parasitoid activity, whether in dual-choice comparisons with either empty oven bags or DCM controls, or when paired with kale plants. Conversely, volatiles from D. intortum were highly attractive to Aphidius colemani (Viereck) (Hymenoptera: Braconidae), a parasitic wasp of aphids. Interestingly, another aphid parasitic wasp, Aphidius ervi (Haliday) (Hymenoptera: Braconidae) was attracted to volatiles from D. intortum only when paired with kales or by kales alone. Gas-chromatography mass spectrometry of D. intortum headspace volatiles revealed 16 compounds: hexanal, (Z)-3-hexenol, p-xylene, o-xylene, nonane, α-pinene, cumene, octen-3-ol, octanone, (Z)-3-hexenyl acetate, sabinene, (E)-β-ocimene, linalool, β-elemene, (E)-β-caryophyllene and an unknown compound. In electroantennography assays, all parasitoid antennae commonly detected hexanal and, (E)-β-ocimene, whilst only C. vestalis and A. ervi registered common antennal responses to (E)-β-caryophyllene. Additionally, the antennae of A. colemani detected cumene, octen-3-ol, (Z)-3-hexenyl acetate and an unknown compound whilst that of A. ervi and C. vestalis detected (Z)-3-hexenol and nonane, respectively. Dose-response olfactometer bioassays with the synthetic standards of hexanal, (E)-β-ocimene and (E)-β-caryophyllene revealed that the response of the three parasitic wasps varied with the concentrations of the individual standards. Specifically, (E)-β-ocimene and hexanal depicted a broad appeal to the tested parasitoids, by eliciting attraction at varying concentrations (P < 0.05). However, (E)-β-caryophyllene was selectively attractive to A. ervi, with no significant attraction observed in C. vestalis (P > 0.05). Our results show species- and -context -specific parasitoid attractive appeal of D. intortum. Nevertheless, our results show that D. intortum may help protect kales against aphid attack through parasitoid recruitment whilst another mechanism may be employed against DBM moth.</p>","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 4","pages":"73"},"PeriodicalIF":2.2,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12226689/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This unveiled at least 12 identifiable compounds, including six quinones, two phenols, and four fatty acid esters. The three most prevalent identifiable compounds were 2,3-dimethoxy-1,4-benzoquinone (25.52%), hexyl pentadecanoate (11.57%) (the first report of a fatty acid ester compound in the order Spirobolida and tentatively indicating that this may be a shared feature of the Juliformia), and 3,4-dimethoxyphenol (10.51%). The antimicrobial activity of the defensive secretions was evaluated against three gram-positive bacteria (Bacillus cereus, Staphylococcus aureus, and S. aureus DMST20654), four gram-negative bacteria (Escherichia coli, E. coli ATCC25922, Pseudomonas aeruginosa, and Salmonella ser. Typhi ATCC16122), and two yeast strains (Candida albicans and C. albicans ATCC10231). The antibiotic kanamycin and the antifungal drug fluconazole were employed as positive controls. Paper disc diffusion assays demonstrated that the fresh, undiluted, secretions inhibited the growth of all tested microorganisms. Furthermore, broth microdilution analysis revealed Minimum Inhibitory Concentrations (MIC) ranging from 40 to 20,000 µg/mL and Minimum Bactericidal/Fungicidal Concentrations (MBC/MFC) ranging from 1,250 to > 20,000 µg/mL. The MIC values indicated that the defensive secretions of C. saratani are notably more efficient than kanamycin and fluconazole in inhibiting the growth of S. aureus DMST20654, E. coli ATCC25922 and C. albicans, but inhibit less effectively the visible growth of the six other microbial taxa tested. Finally, the MBC/MFC values revealed that the secretions of C. saratani may show less potent antimicrobial activity against the nine microbial taxa tested than kanamycin and fluconazole.

While it is well known that floral traits can shape plant-pollinator-pathogen interactions in natural and managed systems, little is known regarding how morphological, phenological, and chemical traits combine to shape resistance in domesticated plant species. Here, we address this topic by (1) conducting a common garden field experiment where we measured percent of tissues infected by the fungal pathogen Monilinia vaccini-corymbosii in 14 cultivars of highbush blueberries (Vaccinium spp.) and (2) using a three-pronged multivariate approach of PCA, random forest, and LASSO regressions to single out predictors of cultivar resistance from a suite of phenological, morphological, and chemical (oxidatively active phenolics) traits collected from the field. Leaf and floral traits varied between cultivars, and we found that concentrations of phenolics (chlorogenic acid and total phenolics) in leaves were strong predictors of cultivar resistance to the primary infection stage of M. vaccini-corymbosii, while floral phenology and carpel phenolics (procyanidin-containing proanthocyanidins and quercetin derivatives) predicted resistance to the secondary infection stage. Our findings highlight that intraspecific variation in chemical and phenological traits as a result of breeding can shape plant-pollinator-pathogen dynamics.

Here, we examine the impact of AM fungi on VOC production in the South American willow tree, Salix humboldtiana. We assessed the effects of inoculation with AM fungi on plant growth and larval feeding by the willow sawfly Nematus oligospilus, as well as its impact on the plant's VOC emission profile. Willow plants inoculated with AM fungi exhibited increased leaf biomass and reduced damage incidence from willow sawfly larvae, supporting the role of mycorrhiza as a protective symbiosis. Notably, AM fungi-inoculated plants emitted 40% less total VOC compared to non-inoculated plants. Both groups emitted similar levels of monoterpenes; however, inoculated plants produced 30% fewer sesquiterpenes. Herbivory did not alter total VOC emission, but non-inoculated plants showed a reduction in (E)-β-ocimene, which was not observed in inoculated plants.

Receiver maize plants were exposed to either constitutive volatile organic compounds (cVOCs) or HIPVs from emitter maize plants, while we manipulated R: FR light conditions of receivers or emitters. Priming responses in the receivers were then assessed by measuring real-time volatile emissions following simulated herbivory. We show that low R: FR light enhances HIPVs emissions in plants previously exposed to HIPVs from neighbours independently of the light conditions of emitters. We also demonstrate that both cVOCs and HIPVs emitted by maize grown under low R: FR amplify HIPVs emissions in their neighbours. This amplified response could not be explained by FR-mediated changes in the release of green leaf volatiles or terpenoids by emitters, thus suggesting the involvement of other VOCs.

To test this, we investigated how female Drosophila melanogaster evaluate substrates with varying concentrations of sugars and amino acids, and whether these preferences correlate with larval survival. Using choice assays, we found that females preferentially deposited eggs on substrates containing 0.1 mol/L sucrose, while higher concentrations (2 mol/L) were consistently avoided-a response not attributable to differences in substrate hardness or prior feeding experience during mating. In contrast, when presented with monosaccharides, females favored intermediate concentrations: 0.5 mol/L for both glucose and fructose, with a marked overall preference for fructose even when combined with an amino acid mixture. Moreover, substrates aligning with the females' oviposition choices often supported best survival of larvae.
