“…In the field of chemical ecology, measuring chemical diversity is becoming increasingly common. However, with a few exceptions (Wetzel and Whitehead 2020, Bakhtiari et al 2021, Ramos et al 2023, Petrén et al 2023), little attention has been paid to how phytochemical diversity is actually measured, and how this is relevant to its function in different ecological contexts.…”

Plants produce a great number of phytochemical compounds mediating a variety of different functions. Recently, phytochemical diversity (chemodiversity), a way which to quantify the complex phenotype formed by sets of phytochemicals, has been suggested to be important for function. However, no study has systematically examined the potential (in)direct functional importance of chemodiversity on a general level, partly due to a lack of an agreement on how to quantify this aspect of the plant phenotype. This paper has four aims: 1) We discuss how chemodiversity (deconstructed into components of richness, evenness and disparity) may quantify different aspects of the phenotype that are ecologically relevant. 2) We systematically review the literature on chemodiversity to examine methodological practices, explore ecological patterns of variability in diversity across different levels of biological organization, and investigate the functional role of this diversity in interactions between plants and other organisms. 3) We provide a framework facilitating decisions on which measure of chemodiversity is best used in different contexts. 4) We outline open questions and avenues for future research in this area. A more thorough understanding of phytochemical diversity will increase our knowledge on the functional role phytochemical compounds, and how they shape ecological interactions between plants and their environment.

“…The pot experiments’ results demonstrated that orange leaf oil (93.06 ± 3.67% at 540.00 g a.i.·hm −2 , 97.22 ± 1.39% at 720 g a.i.·hm −2 , 100.00% at 900.00 g a.i.·hm −2 ), zanthoxylum oil (98.73 ± 1.27% at 900 g a.i.·hm −2 ), and pomelo peel oil (100.00% at 900 g a.i.·hm −2 ) had the highest control efficacy and were the most effective against T. flavus after 7 days of treatment. EOs are complex mixtures of secondary plant metabolites with a significant chemical variability [ 45 , 46 ]. Therefore, the individual or combined properties of the Rutaceae EOs tested against T. flavus could potentially be used to develop alternative pesticides for crop protection.…”

To meet the demand for novel pest management strategies to combat the development of insecticide resistance, plant essential oils may be a promising alternative source. This study investigated the insecticidal activity of five essential oils from the Rutaceae plant family against Thrips flavus Schrank (Thysanoptera: Thripidae) under laboratory conditions. The plant essential oils were citrus oil (Citrus reticulata Blanco), Chuan-shan pepper oil (Zanthoxylum piasezkii Maxim.), zanthoxylum oil (Zanthoxylum bungeanum Maxim.), pomelo peel oil (Citrus maxima (Burm.) Merr.) and orange leaf oil (Citrus sinensis (L.) Osbeck). Among the essential oils evaluated, orange leaf oil (LC50 = 0.26 g/L), zanthoxylum oil (LC50 = 0.27 g/L), and pomelo peel oil (LC50 = 0.44 g/L) resulted in a higher gastric toxicity under laboratory conditions. The results of the pot experiment also showed that orange leaf oil (93.06 ± 3.67% at 540.00 g a.i.·hm−2, 97.22 ± 1.39% at 720 g a.i.·hm−2, 100.00% at 900.00 g a.i.·hm−2) zanthoxylum oil (98.73 ± 1.27% at 900 g a.i.·hm−2), and pomelo peel oil (100.00% at 900 g a.i.·hm−2) exhibited a higher control efficacy, being the most effective against T. flavus after 7 days of treatment. The essential oil components were then identified by gas chromatography–mass spectrometry (GC–MS). The insecticidal activity of orange leaf oil, pomelo peel oil, and zanthoxylum oil could be attributed to their main constituents, such as methyl jasmonate (50.92%), D-limonene (76.96%), and linalool (52.32%), respectively. In the olfactory test, adult T. flavus were attracted by zanthoxylum oil and Chuan-shan pepper oil. We speculated that linalool might be the key signaling compound that attracts T. flavus. These results showed that orange leaf oil, zanthoxylum oil, and pomelo peel oil exhibited insecticidal activities under controlled conditions. They can be implemented as effective and low-toxicity botanical insecticides and synergistic agents against T. flavus.

“…One important concept related to chemical diversity is chemodiversity, which refers to the diversity of chemical compounds found within a given ecosystem [3]. The study of chemodiversity can provide valuable insights into ecological interactions [2]. Moreover, with natural products drawn from these environments acting as an abundant source of novel pharmaceuticals, the chemical variety of tropical rainforests, for instance, has been a propelling factor in drug development efforts [3,4].…”

This study investigated the chemical phenotypical variability of Piper lhotzkyanum Kunth (Piperaceae), a shrub found in Brazilian tropical forests, over time (different periods of the day and seasons) and under natural conditions. For this, essential oils (EOs) from the leaves were collected in different seasons and times of the day and analyzed by gas chromatography coupled with mass spectrometry, and gas chromatography coupled with a flame ionization detector. The indices were applied to evaluate the chemical diversity as well as the dynamics of redox of the mixtures. The results showed that the EOs were dominated by non-oxygenated sesquiterpenes, with β-elemene, E-caryophyllene, and α-zingiberene being the main compounds identified in all collections. Temporal and seasonal analyses revealed important fluctuations in the chemical composition, redox, and chemical diversity indices of the species. A correlation between climatic factors and the variation in redox and chemical diversity was observed, highlighting the chemical phenotypic plasticity P. lhotzkyanum. This study resolves a previously unanswered question by confirming that natural light does not produce interconversion of major compounds. The adaptation capacity of this species to the environmental changes suggests new cultivation strategies to maximize the quality of EO and promote a more sustainable future in partnership with nature.
