“…2 and 4a). We are aware that undamaged eggplants emit very low levels of VOCs consisting of eight major compounds, while damaged eggplants emit much larger quantities and higher quality of VOCs consisting of at least 21 compounds, leading to a stronger attraction of N. tenuis and O. strigicollis towards VOCs from damaged eggplants over those from undamaged eggplant 33 (unpublished results about O. strigicollis response; Rim et al). The question we then asked is how those predators prefer mint VOCs.…”

“…The assays were performed according to the method described previously by Rim et al 33 . Briefly, one N. tenuis individual was introduced at the starting point (2 cm from the downwind end of the main tube) in the Y-tube olfactometer (3.5 cm inner diameter, 13 cm long for the main tube, and 13 cm long for each branch tube) using an insect aspirator made for handling of these predators.…”

Mint plants enable improvement of pest management by attracting herbivore enemies to constitutively released mint volatiles. The generalist predator Nesidiocoris tenuis is used worldwide to control agricultural pests, but little is known about whether mint can serve as a companion plant that attracts this predator. To examine this, olfactory responses of N. tenuis were assessed using apple mint, candy mint, and spearmint as odor sources. Of the volatiles released by these mint species, candy mint volatiles alone were more attractive than those from undamaged eggplant, and were as attractive as volatiles from eggplant damaged with Spodoptera litura larvae. However, no prominent preference for particular volatile(s) among the mint volatiles was shown by O. strigicollis. When N. tenuis had been previously exposed to candy mint, the predator showed a stronger preference for candy mint volatiles than damaged eggplant volatiles. It was, however, irrelevant whether the predator received benefit or not by predating animal prey during the mint-experience period. In contrast, spearmint-experience increased the preference for spearmint volatiles only when the predator acquired prey during the mintexperience period. These findings suggest that previous exposure of N. tenuis to some particular mint species can increase its preference for volatiles from the conspecific mints. Plants produce and emit volatile organic chemicals (VOCs) in order to resist environment stresses such as heat and light 1 , to deter herbivores and pathogenesis 2-4 , and to attract beneficial organisms, including natural enemies of herbivores 5-7 and pollinators 8. The pivotal roles of plant VOCs in the tritrophic system consisting of plant, herbivore, and predator have been intensively researched in a large array of cultivated crops 7 to be applied for use of biological control of herbivores 9. Among such applications, "companion planting" is one successful example of polyculture in which target plants (TPs) are cultivated with companion plants (CPs) to assist TP growth or protection against pests by attracting beneficial insects or repelling pests 10. For example, CPs such as mint, basil and marigold work as attractants for herbivore enemies 11,12. Moreover, an aphid predator, Cycloneda sanguinea L. (Coccinellidae), has been shown to be attracted to corianders owing to their pollen and nectar serving as supplementary foods 13. Recently, Togashi et al. showed that candy mint (Mentha x piperita L. cv. Candy) and spearmint (M. spicata L.) attract Phytoseiulus persimilis Athias-Henriot (Phytoseiidae), a specialized predatory mite of Tetranychidae, but not Neoseiulus californicus McGregor (Phytoseiidae) 14 , a generalized predator that consumes not only mites but also pollen, thrips, and other tiny arthropods 15. These results were certainly unexpected because it was initially expected that the generalist N. californicus rather than the specialist P. persimilis would be responsive to mint VOCs. To the best of our knowledge about companion plants attracting...

“…Olfactory assays towards HIPVs and VOCs from B. distachyon plants were performed as previously described by Rim et al (2015) with slight modifications. B. distachyon plants were exposed to five 3rd-instar M. separata larvae from 10:00 on the 1st day.…”

“…Based on the above findings on rhythmic emission of VOCs from B. distachyon plants, we assessed olfactory responses of the generalist predator N. tenuis to undamaged-plant VOCs vs. damaged-plant VOCs in the light and dark conditions. N. tenuis is an omnivorous mirid bug with diverse prey, including lepidopteran larvae/eggs such as those of S. litura (Wei et al 1997;Rim et al 2015). Both females and males of N. tenuis preferred VOCs from damaged plants over undamaged plants in both light and dark conditions (Figure 3(a,b)) (male: light phase, P < 0.001 and dark phase, P < 0.01; female, light phase: P < 0.05, dark phase: P < 0.001, G-test).…”

Diurnal rhythm of volatile emissions from grasses in response to herbivory may temporally affect the oviposition behaviors of the conspecific herbivores and prey searching of natural enemies of the herbivores in a diurnal cycle of the ecosystem. We assessed volatiles emitted from the temperate grass Brachypodium distachyon L. (Poaceae) damaged by Mythimna separata Walker (Noctuidae), a specialist herbivore of Poaceae, in light/dark cycle conditions. Volatiles were preferentially emitted from the damaged plants in both light and dark phases, but their quantitative compositions were different. The generalist predator Nesidiocoris tenuis Reuter (Miridae) was attracted to the damaged plants in both light and dark conditions. However, adult females of M. separata preferred to oviposit on undamaged plants mostly in the dark owing to the cue of undamaged plant volatiles, partly in a circadian rhythm-dependent manner. The findings suggested that volatiles released in the dark contribute to both plant-herbivore and plant-herbivore enemy communications.

“…Such evidence has also been obtained for N. tenuis, M. pygmaeus and O. laevigatus, who responded to the odour emitted from prey infested plants (Moayeri et al, 2006;Ingegno et al, 2011;Lins et al, 2014;De Backer et al, 2015;Rim et al, 2015Rim et al, , 2017Vaello et al, 2017). Recently, the activity (feeding behaviours and oviposition) of zoophytophagous predators was observed to induce HIPVs (De Puysseleyr et al, 2011;Pérez-Hedo et al, 2015a, 2015bPappas et al, 2015Pappas et al, , 2016Naselli et al, 2016 …”
