“…Incorporating high functional biodiversity through different cropping systems contributes to maintaining ecological functions that help pest management (Altieri et al, 2015). For aerial pests case, intercropping has proven to be particularly effective because companion plants play multiple roles, serving as repellents, reservoirs for natural enemies, and creating visual and olfactory barriers (Togni et al, 2016;Carvalho et al, 2017;Pouët et al, 2022). For example, Mutisya et al (2016) observed that a row of aromatic basil (Ocimum basilicum L.) as companion cropping between adjacent tomato rows significantly lowered whitefly (Bemisia tabaci Genn) infestation in tomatoes by 68.7% and resulted in 13.75 t/ha −1 as tomato yield compared to 5.9 t/ha −1 in the control because attractive nature of the basil plant makes it a better host for insects such as B. tabaci.…”

Sustainable agriculture has become a global priority in response to increasing food demand and the challenges confronting agricultural production, such as biotic and abiotic stresses. In this review, we delve into the role of plant diversity in mitigating these stressors within tomato cultivation. Our investigation reveals that the most extensively studied companion species are Vicia villosa Roth, Coriandrum sativum L., and Allium cepa L., while the primary stressors under scrutiny include nutrient deficiencies, aerial pests, and soil-borne pathogenic diseases. Regarding nutrient deficiencies, the cover crop system has demonstrated its capacity to provide essential nutrients directly and indirectly to plants. In addressing aerial pests and pathogens, all cultivation systems exhibit contributions. Finally, we assert that incorporating plant diversity into agroecosystems can effectively counteract various types of stressors. These benefits align with the application of agroecological principles and the development of sustainable agroecosystems. Further assessments of the effects of additional companion plant species are imperative. This should encompass the identification of their distribution, optimal plant quantities, and cultivation systems that enhance their benefits. Ultimately, these evaluations will aid in the formulation of comprehensive guidelines to facilitate the selection and utilization of plant diversity for long-term sustainability.

“…Behaviour in relation to the stimulus or stimuli is scored in one of several ways: counting study subjects moving toward or touching a stimulus, time spent by study subjects within a pre‐determined distance of the stimulus, or time taken for study subjects to respond to the stimulus (Knolhoff & Heckel, 2014). Although many studies have successfully used still air olfactometers for different insect taxa (e.g., Weeks et al, 2011; Hennessy et al, 2022; Pouët et al, 2022), there are experimental limitations to using this apparatus.…”

Olfactometers have been used for more than 100 years and are integral to experimental chemical ecology. Studies utilising olfactometer bioassays form the foundation for understanding the behavioural responses of invertebrates to chemical stimuli under standardised laboratory conditions. Widely used olfactometry apparatuses include two‐arm olfactometers for binary responses through to four‐ and six‐arm arenas to evaluate more complex behaviours. Despite its prevalence in chemical ecology studies, there has never been a review of experimental best practice in olfactometry. This review critically evaluates both olfactometry methods and applications as well as experimental design and analysis. We aim to outline a standard of good practice to improve experimental design and reporting for studies involving olfactometry, thereby establishing a reference guide to build a robust experimental workflow for olfactometry bioassays.

“…For example, VOCs emitted by coriander were not repellent by themselves but reduced the attractiveness of tomato VOCs for the silverleaf whitefly, Bemisia tabaci [ 191 ]. VOCs from oregano were also found to be repellent and mask tomato VOCs for the silverleaf whitefly [ 192 ]. Potentially, the repellent compounds in the oregano VOC blends were ( E )-β-caryophyllene and α-humulene, also proposed as repellent compounds for stem borer pests in the maize/sorghum system.…”

Agricultural crop productivity relies on the application of chemical pesticides to reduce pest and pathogen damage. However, chemical pesticides also pose a range of ecological, environmental and economic penalties. This includes the development of pesticide resistance by insect pests and pathogens, rendering pesticides less effective. Alternative sustainable crop protection tools should therefore be considered. Semiochemicals are signalling molecules produced by organisms, including plants, microbes, and animals, which cause behavioural or developmental changes in receiving organisms. Manipulating semiochemicals could provide a more sustainable approach to the management of insect pests and pathogens across crops. Here, we review the role of semiochemicals in the interaction between plants, insects and microbes, including examples of how they have been applied to agricultural systems. We highlight future research priorities to be considered for semiochemicals to be credible alternatives to the application of chemical pesticides.
