The Guatemalan moth Tecia solanivora is an invasive pest of potato in Central and South America. The larvae infest potato tubers in the field as well as in storage facilities. The headspace of potato foliage and potato tubers was studied with regard to volatiles that mediate host-finding and oviposition in the Guatemalan moth. Foliage of three phenological stages, from sprouting to tuberization and flowering, released more than 30 sesquiterpenes. The main compounds were beta-caryophyllene, germacrene-D-4-ol, germacrene-D, kunzeaol, and (E,E)-alpha-farnesene. Sesquiterpenes accounted for >90% of the headspace of green plants, whereas fresh potato tubers emitted only trace amounts of a few sesquiterpenes. Screening of headspace collections with antennae of Guatemalan moth females showed a strong response to several sesquiterpenes and monoterpenes that were emitted from foliage only. In addition, antennae responded to methyl phenylacetate, a floral fragrance that was released in large amounts from flowering plants and that was also present in tuber headspace. Female and male moths were attracted to methyl phenylacetate; this compound may accordingly contribute to female attraction to tuber-bearing potato plants in the field as well as to potato tubers in storage. Oviposition tests showed that females lay eggs near mature flowering plants. Eggs were laid in soil close to the plant and not on potato stems and foliage, which may be due to avoidance of terpenoid compounds released from green plant parts at close range. The results support the concept that potato volatiles mediate host-finding and oviposition behavior and that these compounds may become useful tools for management of the Guatemalan moth.

“…Support for potential associational resistance for R. tomentosum-neighbouring species comes from earlier studies. R. tomentosum extracts, with myrcene and palustrol as main compounds, had repellent effects on ticks (Ixodes ricinus) (Jaenson et al, 2005) and mosquitoes (Jaenson et al, 2006), yet isolated ledol had no effect on feeding of the Colorado beetle (Leptinotarsa decemlineata Say) (Szafranek et al, 2006). Instead, ledol induced an electroantennographic response in mahogany shoot borers (Hypsipyla grandella, Lepidoptera: Pyralidae) and was suggested partly to account for their orientation to Guarea macrophylla trees (Lago et al, 2006).…”

Birch (Betula spp.) leaves adsorb and re‐release volatiles specific to neighbouring plants – a mechanism for associational herbivore resistance?

Summary• Plant-emitted semi-volatile compounds have low vaporization rates at 20-25°C and may therefore persist on surfaces such as plant foliage. The passive adsorption of arthropod-repellent semi-volatiles to neighbouring foliage could convey associational resistance, whereby a plant's neighbours reduce damage caused by herbivores.• We found that birch (Betula spp.) leaves adsorb and re-release the specific arthropod-repelling C 15 semi-volatiles ledene, ledol and palustrol produced by Rhododendron tomentosum when grown in mixed association in a field setup. In a natural habitat, a higher concentration of ledene was released from birches neighbouring R. tomentosum than from birches situated > 5 m from R. tomentosum. Emission of a-humulene, a sesquiterpene synthesized by both Betula pendula and R. tomentosum, was also increased in R. tomentosum-neighbouring B. pendula.• In assessments for associational resistance, we found that the polyphagous green leaf weevils (Polydrusus flavipes) and autumnal moth (Epirrita autumnata) larvae both preferred B. pendula to R. tomentosum. P. flavipes also preferred birch leaves not exposed to R. tomentosum to leaves from mixed associations. In the field, a reduction in Euceraphis betulae aphid density occurred in mixed associations.• Our results suggest that plant ⁄ tree species may be protected by semi-volatile compounds emitted by a more herbivore-resistant heterospecific neighbour.

“…Several sVOCs and many less volatile hydrophobic compounds have been described on leaf surface epicuticular waxes of crop plants (e.g. Szafranek et al 2006Szafranek et al , 2008. However, the understanding of deposition of VOCs and sVOCs on target plant leaves from their neighbours is often masked by the emission of similar compounds from both plant species.…”

Plants emit an extremely diverse bouquet of volatile organic compounds (VOCs) from their above-ground and below-ground parts. Emissions are constitutive or induced, e.g. by herbivores. VOCs can be classified as highly volatile, volatile and semivolatile compounds. Sesquiterpenes (SQTs) are typical semi-volatile organic compounds (sVOCs) released by plants. Similarly, herbivore-induced homoterpenes and methyl salicylate also have relatively low volatility. SVOCs have a high boiling point (> 240 °C) and a vapour pressure below 0.005 kPa at 25 °C. Glandular trichomes on plant surfaces can store SQTs in mixtures with more volatile VOCs, which are released into the air by diffusion or after gland rupture. The sVOCs stored in glandular trichomes often have repellent effects on herbivores, while herbivore-induced sVOCs are known for their attractiveness to natural enemies of herbivores, i.e. they act in indirect chemical defence of plants. Due to their low volatility, sVOCs produced by plants may easily adhere to the surfaces of emitter and neighbouring plants during the colder temperatures that plants face, e.g. at night. On the foliage of neighbouring receiver plants, sVOCs may act in direct and indirect defence of that plant species. When the temperature rises again, sVOCs are released into the atmosphere. The semi-volatile reaction products of highly volatile plant monoterpenes and photochemical pollutants such as ozone could constitute further sVOCs on plant leaf surfaces. Here, we review recent literature of the plant surface-environment interaction of biogenic sVOCs and particularly evaluate potential crop protection strategies such as intercropping and companion planting using sVOC-emitting species. Foliage typically forms the widest surfaces on crop plants, and foliar herbivory is a major type of pest damage during the vegetative stage of crop plants. Foliage is also a major source of herbivore-induced VOC emissions. Consequently, we focus on foliage-mediated sVOCs and their potential in pest management.
