On April 28, 2021, Zhang, Zhenfei; Liu, Yong; Portaluri, Vincent; Woodcock, Christine; Pickett, John A.; Wang, Senshan; Zhou, Jing-Jiang published an article.Recommanded Product: 1,2-Dimethoxybenzene The title of the article was Chemical Identity and Functional Characterization of Semiochemicals That Promote the Interactions between Rice Plant and Rice Major Pest Nilaparvata lugens. And the article contained the following:
The interaction between food crops and insect pests is mediated by semiochems. emitted from host plants. These semiochems. are natural behavioral modifiers and act on the insect olfactory system to locate hosts and preys. In this study, eight rice neuroactive semiochems. were identified from rice varieties by GC-EAG and GC-MS. Their ability to modify rice pest behaviors was further studied as individual chems. and physiol. relevant blend. The total amount of each semiochem. and the expression of their biosynthesis genes were significantly higher in pest susceptible variety than in pest-resistant variety and upregulated by the infestation of the pest Nilaparvata lugens (BPH). The semiochems. emitted by uninfested plants (UIRVs) were more attractive to BPHs. Interestingly, the attractiveness of UIRVs was significantly reduced by the addition of the blend that mimics the natural composition of these semiochems. emitted by infested plants (IRVs). Our study suggests a mechanism for the spread of pest infestation from infested plants to uninfested plants nearby. UIRVs initially serve as attractive signals to rice insect pests. The pest infestation changes the rice semiochem. profile to be less attractive or even repellent, which pushes further colonization to uninfested plants nearby. The identified semiochems. can be used for crop protection based on a push-pull strategy. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 1,2-Dimethoxybenzene
