“…Therefore, it is necessary to develop a more sustainable control method to manage them in maize crop systems. The recruitment of natural enemies through sentinel and smart plants is a promising alternative integrated pest management (IPM) strategy (Birkett & Pickett, 2014; Pickett & Khan, 2016; Michereff et al, 2021). Sentinel and smart plants are cultivars and modified plants with traits that allow them to respond earlier to stress and then signal neighbouring plants regarding imminent danger (Pickett & Khan, 2016).…”

Plants respond indirectly to herbivore injury in a species‐specific way and emit a specific blend of volatiles that are attractive to the enemies of herbivores. We evaluated whether maize plants, Zea mays L. (Poaceae), can recognize herbivory damage from a generalist stink bug, Diceraeus melacanthus Dallas (Hemiptera: Pentatomidae). This species is not a common pest in maize, but is currently found on maize crops in Brazil. We aimed to answer the following questions: (1) does D. melacanthus use maize plant volatiles for host location? (2) Do maize plant chemical volatile profiles change due to feeding by D. melacanthus? And (3) do herbivore‐induced plant volatiles (HIPVs) emitted by maize plants play a role in the foraging behaviour of the generalist stink bug egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Scelionidae)? The results show that females of D. melacanthus do not use constitutive volatiles or HIPVs as host location cues. However, feeding by D. melacanthus activates maize indirect defence, inducing emission of HIPVs and attracting the herbivore's enemy. Thus, strengthening indirect defence of plants can be a strategy to protect crops in the field by recruiting natural enemies through chemical information, as an additional approach to control D. melacanthus within an integrated pest management program.

“…There are challenges that need to be considered in the development of attractants and deployment in field applications. Moreover, results from several studies have suggested that blends of active volatiles attract more natural enemies compared with single active volatile 12,13,54 . Therefore, preparing blends of the identified active volatiles and evaluating their activities at their optimal concentration and ratio, are essential to the maximization of the benefits of HIPVs.…”

BACKGROUNDHippodamia variegata (Goeze) (Coleoptera: Coccinellidae), a dominant predatory natural enemy species in cotton‐planting, is a key biological control agent for aphids in China. Our previous study showed that herbivore‐induced plant volatiles (HIPVs) from Glycyrrhiza uralensis (Fisch.) (Fabales: Fabaceae) and Alhagi sparsifolia (Desv.) (Fabales: Fabaceae) plants infested with Aphis atrata (Zhang) (Homoptera: Aphididae), were important semiochemicals for Hippodamia variegata to locate aphids. However, little was known about the varieties and function of active volatiles from HIPVs of the two plant species.RESULTSIn this study, results from gas chromatography‐electroantennography detection (GC‐EAD) demonstrated that seven HIPVs (butyl acrylate, α‐pinene, butyl isobutyrate, β‐pinene, butyl butyrate, 1,3‐diethylbenzene and 1,4‐diethylbenzene) identified from the two damaged plant species elicited antennal responses from Hippodamia variegata. Also, results from gas chromatograph–mass spectrometry (GC–MS) analysis showed that the concentrations of the seven active volatiles were significantly higher than those from corresponding healthy plants. Hippodamia variegata exhibited varying degrees of response to each active volatile in electroantennography (EAG) trials, however, only α‐pinene, butyl isobutyrate, β‐pinene and butyl butyrate significantly attracted Hippodamia variegata in behavioral trials conducted in the laboratory. They also had a better trapping effect on Hippodamia variegata in cotton fields.CONCLUSIONFour active compounds (α‐pinene, butyl isobutyrate, β‐pinene and butyl butyrate) identified from two damaged plant species were considered the most effective HIPVs that attract Hippodamia variegata. These findings provide possibilities for the development of Hippodamia variegata attractants. They also provide a theoretical basis for the biological prevention and control of aphids using Hippodamia variegata. © 2023 The Authors.

“…These phenomena have been demonstrated in many herbaceous species in the laboratory and in the field e.g. [72][73][74][75]. Research has shown that HIPV-exposed trees had enhanced expression of herbivore defense-related genes, and increased levels of protease inhibitors, phenolic compounds, jasmonic acid, and linolenic acid [58,61].…”

Tree Communication: the Effects of “Wired” and “Wireless” Channels on Interactions with Herbivores

Purpose of Review Approximately 40 years ago, key papers indicating that volatile chemicals released by damaged plants elicited defense-related changes in their neighbors, brought prominence to the idea of plant communication. These studies were conducted with several tree species and the phenomenon observed was dubbed “talking trees.” Today there is a wealth of evidence supporting the idea that plants can send and receive information both above and belowground. However, while early reports of plant-plant communication concerned trees, the literature is now heavily biased towards herbaceous plants. The purpose of this review is to highlight recent research on tree-tree communication with an emphasis on synthesizing knowledge on the ecological relevance of the process. Recent Findings Aboveground, information is often provided in the form of biogenic volatile organic compounds (VOCs), which are released by both undamaged and damaged plants. The blends of VOCs released by plants provide information on their physiological condition. Belowground, information is conveyed through mycorrhizal networks and via VOCs and chemical exudates released into the rhizosphere. Recent findings have indicated a sophistication to tree communication with more effective VOC-mediated interactions between trees of the same versus a different genotype, kin-group, or chemotype. Moreover, common mycorrhizal networks have been shown to convey stress-related signals in intra- and interspecific associations. Together these two forms of communication represent “wireless” and “wired” channels with significance to facilitating plant resistance to herbivores. Summary In this review, we examine tree-tree communication with a focus on research in natural forest ecosystems. We particularly address the effects of tree-tree communication on interactions with herbivorous insects. Aboveground and belowground interactions are both reviewed and suggested implications for forest management and future research are presented.
