“…The responses of F. occidentalis to volatiles of different flowers were tested using a four‐arm olfactometer, as described in Abdullah et al . and Liu et al . The olfactometer consisted of a central glass chamber (12 cm internal diameter, 1.5 cm height) with four arms (3 mm internal diameter, 5 cm length), each connected to a glass tube (3 mm internal diameter, 10 cm length).…”

BACKGROUND Differences in population densities of Frankliniella occidentalis among different plant species suggest a preference for particular hosts. Host plant volatiles are often involved in insect fitness. However, few studies have explored the interaction between flower volatiles and fitness. The host fitness of F. occidentalis for different flowers was assessed through field investigation, and the olfactory preference of thrips for flower volatiles was tested in the laboratory. RESULTS In the field study, 18 flower host plants were classified at four fitness levels by F. occidentalis. Olfactory tests showed that female F. occidentalis had significantly different preferences for different plant odours among the volatiles of the four tested flowers (each representing the four fitness levels), whereas male F. occidentalis did not. The relative response of F. occidentalis females to flower volatiles (Rosa rugosa > Dianthus caryophyllus > Gerbera jamesonii > Pelargonium hortorum) was consistent with the field performance of F. occidentalis. In total, 23, 29, 16 and 26 components were identified in the volatile profiles of R. rugosa, D. caryophyllus, G. jamesonii and P. hortorum, respectively. 3,5‐Dimethoxytoluene (24.94%), nonanal (30.42%), (E)‐3‐penten‐2‐one (52.31%) and zingiberene (29.88%) were the single most abundant components of the volatiles of R. rugosa, D. caryophyllus, G. jamesonii and P. hortorum, respectively. CONCLUSION Volatiles are important in attracting F. occidentalis to suitable hosts, and differences in the types and concentrations of volatile components among flowers may directly influence the olfactory responses and field performance of thrips. Potential attractants could be developed for integrated pest management programmes against this pest. © 2018 Society of Chemical Industry

“…Among volatile terpenoids, 1,8-cineole emitted from damaged roots of oak attract larvae of the cockchafer Melolontha hippocastani (Weissteiner et al, 2012) (Figure 1). Similarly, b-pinene has been recognized as a volatile attractant for root-feeding larvae of the cochineal scale, Porphyrophora sophorae, an oligophagous pest of Chinese liquorice, Glycyrrhiza uralensis (Liu et al, 2016). Interestingly, the attractiveness of these root-specific volatile cues can be compromised in the presence of endophytic mutualists of the host plant.…”

Small molecules below‐ground: the role of specialized metabolites in the rhizosphere

Soil communities are diverse taxonomically and functionally. This ecosystem experiences highly complex networks of interactions, but may also present functionally independent entities. Plant roots, a metabolically active hotspot in the soil, take an essential part in below-ground interactions. While plants are known to release an extremely high portion of the fixated carbon to the soil, less information is known about the composition and role of C-containing compounds in the rhizosphere, in particular those involved in chemical communication. Specialized metabolites (or secondary metabolites) produced by plants and their associated microbes have a critical role in various biological activities that modulate the behavior of neighboring organisms. Thus, elucidating the chemical composition and function of specialized metabolites in the rhizosphere is a key element in understanding interactions in this below-ground environment. Here, we review key classes of specialized metabolites that occur as mostly non-volatile compounds in root exudates or are emitted as volatile organic compounds (VOCs). The role of these metabolites in below-ground interactions and response to nutrient deficiency, as well as their tissue and cell type-specific biosynthesis and release are discussed in detail.

“…The chemical ecology of plant–insect interactions is an important aspect to consider when developing integrated pest management (IPM) programmes for specialty crop production. For example, many herbivores use plant volatiles in host‐finding (Liu et al ., ), as well as mating (Tooker et al ., ) and oviposition (Coapio et al ., ). In addition, plant‐derived volatiles often play a vital role in the recruitment of natural enemies as bodyguards for plants (Dicke, ).…”

Volatiles released by Chinese liquorice roots mediate host location behaviour by neonate Porphyrophora sophorae (Hemiptera: Margarodidae)

Abstract: Newly eclosed larvae of P. sphorae exploit root volatiles as chemical cues to locate their host plant. β-Pinene proved to be the major chemical cue used by P. sphorae neonates searching for roots of their host plant. © 2016 Society of Chemical Industry.
