“…Meanwhile, Wang et al . confirmed that ( E )-β-caryophyllene functions as a host-locating signal for WBPH40. Green leaf volatiles are products of the hydroperoxide lyase branch of the oxylipin pathway, and have important roles during plant defence responses to both insect pests and pathogens41.…”

Viruses may induce changes in plant hosts and vectors to enhance their transmission. The white-backed planthopper (WBPH) and brown planthopper (BPH) are vectors of Southern rice black-streaked dwarf virus (SRBSDV) and Rice ragged stunt virus (RRSV), respectively, which cause serious rice diseases. We herein describe the effects of SRBSDV and RRSV infections on host-selection behaviour of vector and non-vector planthoppers at different disease stages. The Y-tube olfactometer choice and free-choice tests indicated that SRBSDV and RRSV infections altered the attractiveness of rice plants to vector and non-vector planthoppers. The attractiveness was mainly mediated by rice volatiles, and varied with disease progression. The attractiveness of the SRBSDV- or RRSV-infected rice plants to the virus-free WBPHs or BPHs initially decreased, then increased, and finally decreased again. For the viruliferous WBPHs and BPHs, SRBSDV or RRSV infection increased the attractiveness of plants more for the non-vector than for the vector planthoppers. Furthermore, we observed that the attractiveness of infected plants to planthoppers was positively correlated with the virus titres. The titre effects were greater for virus-free than for viruliferous planthoppers. Down-regulated defence genes OsAOS1, OsICS, and OsACS2 and up-regulated volatile-biosynthesis genes OsLIS, OsCAS, and OsHPL3 expression in infected plants may influence their attractiveness.

“…β-caryophyllene is a typical terpenoid emitted by many kinds of plants, and β-caryophyllene plays an essential role in attracting or avoiding phytophagous insects. For example, the honeybee Apis cerana can use β-caryophyllene to locate its host flower, Jacquemontia pentanthos 49 ; β-caryophyllene also functions as a host-locating signal for the rice white-backed planthopper 50 . However, other studies have indicated that β-caryophyllene can repel insects 51–53 or even be toxic to insects 54 .…”

“…Thus, the observed difference in the amount of parasitism of WBPH eggs between bismerthiazol-treated and untreated plants is probably due mainly to the difference in volatile amounts between the two groups of plants. Surprisingly, bismerthiazol treatment decreased the production of all detected volatiles from WBPH-infested plants, including the three chemicals attractive to the parasitoid: linalool, MeSA and ( E )-β-caryophyllene [ 41 , 55 , 57 ] ( Table 1 ). Similarly, in maize, treatment with BTH or laminarin is reported to reduce herbivore-induced volatile emissions but increase the plant’s attractiveness to parasitoids [ 24 ].…”

Chemical elicitors that enhance plant resistance to pathogens have been extensively studied, however, chemical elicitors that induce plant defenses against insect pests have received little attention. Here, we found that the exogenous application of a commonly used bactericide, bismerthiazol, on rice induced the biosynthesis of constitutive and/or elicited jasmonic acid (JA), jasmonoyl-isoleucine conjugate (JA-Ile), ethylene and H2O2 but not salicylic acid. These activated signaling pathways altered the volatile profile of rice plants. White-backed planthopper (WBPH, Sogatella furcifera) nymphs and gravid females showed a preference for feeding and/or oviposition on control plants: survival rates were better and more eggs were laid than on bismerthiazol-treated plants. Moreover, bismerthiazol treatment also increased both the parasitism rate of WBPH eggs laid on plants in the field by Anagrus nilaparvatae, and also the resistance of rice to the brown planthopper (BPH) Nilaparvata lugens and the striped stem borer (SSB) Chilo suppressalis. These findings suggest that the bactericide bismerthiazol can induce the direct and/or indirect resistance of rice to multiple insect pests, and so can be used as a broad-spectrum chemical elicitor.
