“…Nevertheless, several of the antennally inactive compounds of T. occidentalis ‘Smaragd’, derived by hydrodistillation, identified either in the present or in earlier studies (Szolyga et al, 2014), may serve as host‐finding cues for other insect species. Similarly, certain compounds identified in the present study from T. occidentalis ‘Smaragd’ were also identified from headspace volatiles of oriental arborvitae, Platycladus orientalis (L.) Franco, in the context of behaviour of P. aubei (Zheng et al, 2021).…”

The cypress jewel beetle, Ovalisia festiva L. (Coleoptera: Buprestidae, Chrysochroinae), and the cypress bark beetle, Phloeosinus aubei Perris (Coleoptera: Curculionidae, Scolytinae), are invasive wood‐boring pests of scale‐leafed conifers (Cupressaceae), threatening tree nurseries and urban green areas. In order to reveal which volatile compounds of their common host, the American arborvitae, Thuja occidentalis L. cultivar ‘Smaragd’, they can perceive, we collected headspace volatiles from live attached twigs and screened them for bioactivity by gas chromatography coupled to an electroantennographic detector (GC‐EAD). Compounds eliciting antennal responses were identified by gas chromatography coupled to mass spectroscopy (GC‐MS). Synthetic samples of bioactive compounds were then screened by electroantennography. GC‐EAD analyses of volatile collections revealed that E–β–caryophyllene elicited antennal responses only from O. festiva (from both sexes), whereas borneol only from P. aubei. Electroantennography screening of synthetic compounds showed further differences between the two species. Even many of those compounds, which elicited responses from both species, differed in the relative intensities of responses they evoked. This indicates that O. festiva and P. aubei probably use different key compounds in the Thuja volatile blend for host recognition.

[22][23][24][25][26][27][28][29][30][31][32][33] Abscisic acid (ABA) plays a crucial role in promoting senescence and abscission, and it also enhances plant resistance to abiotic and biotic stressors. More recently, the exogenous application of ABA was shown to induce resistance to N. lugens in rice, which decreased the damage incited by the brown planthopper.…”

BackgroundOver the course of evolution, plants have developed various sophisticated defense mechanisms to resist pests and diseases. The phytohormone abscisic acid (ABA) has an important role in the growth and development of plants and confers tolerance to selected abiotic stressors, such as drought. Prior studies have shown that ABA promotes the deposit of callose in response to piercing/sucking insect pests. The English grain aphid, Sitobion avenae Fabricius, causes huge losses in rice and is especially harmful to rice seedlings.ResultsExogenous ABA promoted growth and reduced the feeding behavior of S. avenae nymphs in rice. Our results suggested that enhanced trichome density and increased expression of related genes may be associated with rice resistance to aphids. An analysis of volatiles revealed the production of seven compounds associated with pest resistance.ConclusionThese results indicate that ABA reduces aphid feeding in rice. Our findings provide a basis for understanding ABA‐mediated defense responses in rice and provide insights on more environmentally‐friendly approaches to control.

“…The collaboration between chemists and biologists, and the introduction of newer analytical techniques, enabled the development of additional approximations to pheromone research or bioactive compounds characterization by untargeted metabolomics (Butcher, 2017;Hefetz, 2019;Li et al, 2018). Most of the studies have focused on the volatile pheromones of different organisms and the employment of GC-MS or GC-HRMS instruments to this aim: in yeast (Ljunggren et al, 2019), insects (Esteves et al, 2017) and plants (Hosseini et al, 2021;Zheng et al, 2021). For more polar pheromones, LC-HRMS was used in marine planktonic diatoms (Fiorini et al, 2020) and nematodes (Falcke et al, 2018;Le et al, 2020),…”

Des échantillons ont été prélevés en frottant doucement des écouvillons sur les zones faciales et anogénitales des souriceaux. Les extraits ont été analysés par LC-IMS-HRMS et 5 composés ont été provisoirement identifiés à partir de souris néonatales avec une possible implication dans la communication mère-enfant.
