“…Earlier studies reported lower abundances of TGLs in the intercropped tea plantations than in bare ground or in rows with traditional clearing tillage . Compared to the bare ground treatment, we also found an indication that cover crops influence TGL abundance in tea canopies.…”

BACKGROUND Empoasca onukii, the tea green leafhopper, is a key pest of tea whose control often requires the extensive use of insecticides. As a predator of the tea green leafhopper, the mite Anystis baccarum is a potential biological control agent worldwide, though little is known about how intercropping cover crops can impact its suppressing effect on E. onukii. Therefore, we conducted a field experiment to investigate how the relationship of the abundance of the predatory mite and its leafhopper prey is influenced by two different cover crops and a manually weeded inter‐row treatment as a contrast to naturally growing vegetation in a tea plantation in China. RESULTS The abundance of A. baccarum was significantly higher in tea canopies of intercropped treatments than in canopies over natural ground cover. Litter samples showed higher abundances of A. baccarum when tea was intercropped with Paspalum notatum than with natural ground cover in the first year of treatment. The abundance of E. onukii in tea canopies was higher over the bare ground treatment in the first year but the opposite was observed in the second year. CONCLUSIONS Results suggest that the abundance of A. baccarum in a tea plantation is influenced by intercropping and it can affect its leafhopper prey, albeit with varying levels of suppression. For informing biological control and suppression of pests, long‐term experiments are needed to investigate the interactions of both pest and predator with cover crop treatments. © 2019 Society of Chemical Industry

“…The sex pheromones of the tea green leafhopper and tea volatiles could be used as potential biological agents for its management through mating disruption or mass trapping strategy. Through collecting and analysing the volatiles released by the tea plants, we found the tea green leafhopper are very attracted to several compounds [( E )‐2‐hexenal, ( E )‐ocimene and linalool; Cai et al., ; Mu et al., ] and repelled by particular compounds ( p ‐cymene, limonene and 1,8‐cineole; Zhang, Luo, et al., ; Zhang, Sun, Luo, Bian, & Chen, ). The antennae‐specific or enriched OBPs and CSPs may participate in the attracting and repelling behaviours.…”

“…Previous researches have shown that the E. onukii was significantly attracted by the tea, peach and grapevine plant volatiles and volatile compounds such as ( E )‐2‐hexenal, ( E )‐ocimene and linalool (Cai et al., ; Mu et al., ), and repelled by the volatiles of non‐host plants Lavandula pinnata and volatile compounds such as p ‐cymene, limonene and 1,8‐cineole (Zhang, Luo, et al., ; Zhang, Sun, Luo, Bian, & Chen, ). In recent years, the olfaction‐based approaches, using host plant volatiles to attract E. onukii and using non‐host plant volatiles to mask host odours or evoke non‐host avoidance and repellent behaviours of E. onukii , have been successfully applied to control the E. onukii in the tea plantations (Mu et al., ; Zhang & Chen, ; Zhang, Sun, et al., ; Zhang, Zhou, et al., ). Identification and annotation of olfactory‐related proteins in E. onukii are required to well understand the molecular and cellular mechanisms underlying volatiles detection in E. onukii .…”

Tea green leafhopper, Empoasca onukii Matsuda, is one of the major dominant insect pests affecting tea plantations in Asia. Previous studies have demonstrated that E. onukii was significantly attracted by the tea volatiles and repelled by the non‐host plant volatiles. However, the olfactory mechanisms of insect perception of these semiochemicals are still unknown. Odorant‐binding proteins (OBPs) and chemosensory proteins (CSPs) are involved in the initial biochemical recognition steps in semiochemical perception. In this study, a total of 33 OBPs and 24 CSPs were identified in the antennae and body transcriptomes of E. onukii. Among them, 9 OBPs and 17 CSPs were newly identified. Phylogenetic analysis was conducted to compare OBPs and CSPs among Hemiptera insects. Semi‐quantitative RT‐PCR and real‐time quantitative PCR analysis revealed that 24 EonuOBP and 13 EonuCSP genes were mainly or uniquely expressed in the antennae. In addition, one OBP (EonuOBP49) and four CSPs (EonuCSP4, 7, 12 and 18) were more highly expressed in the body than in the antennae. Overall, the present work had provided foundational data to study the physiological roles of the OBPs and CSPs in the tea green leafhopper both in vitro and in vivo.

BACKGROUND The tea leafhopper, Empoasca onukii Matsuda (Hemiptera: Cicadellidae), is a major pest of tea plants in China. Here, we evaluated the repellent properties of eight volatile chemicals alone and in various combinations as tools for the management of this pest in tea gardens. These chemicals were from the Alliaceae and other aromatic plants, and are known to repel various insect species. RESULTS Among the eight volatile compounds, dimethyl disulfide (DMDS), 1,8‐cineole and allyl methyl sulfide were significantly repellent towards E. onukii adults. DMDS and 1,8‐cineole were mixed to formulate a binary repellent. Under field conditions, spraying and slow‐release applications of the mixture significantly decreased the density of E. onukii adults. The repelling effect after spraying was very short, only ∼ 2 days, but the slow‐release mixture had a longer term repelling effect on E. onukii adults. High emission of the slow‐release mixture, which was achieved by increasing the number of slow‐release bottles, had a stronger repellent effect than low emission. Moreover, when the amount emitted was sufficient, the slow‐release mixture significantly decreased the number of leafhopper nymphs in a treated tea‐plant line, and significantly decreased the number of leafhopper adults and nymphs in a tea‐plant line adjacent to the treated area. CONCLUSION This study demonstrates the repellent action of a mixture of DMDS and 1,8‐cineole applied by a slow‐release method against E. onukii in a tea plantation. This mixture has potential applications in integrated pest management schemes. © 2019 The Authors.
