对褐飞虱有功能效应的水稻挥发物活性组分的筛选与鉴定
Screening and Identification of Active Components of Rice Volatiles with Functional Effects on Brown Planthopper,Nilaparvata lugens(Stål)
摘要
Abstract
The difference of chemical components of rice volatiles released by the resistant variety Mudgo and the susceptible variety TN 1 was assessed in relation to their functional effects on the brown planthopper,Nilaparvata lugens(Stål).Volatiles were obtained by headspace dynamic collection,and the active components of rice volatiles were screened and identified by gas chromatography-mass spectrometry(GC-MS).The functions of the differentially active volatiles of Mudgo and TN1 rice were verified by Y-type.As a result,a total of 52 volatile chemicals were identified in the volatiles of the two rice varieties,among which 27 chemicals were identified in both Mudgo and TN1,10 chemicals were present only in Mudgo and 15 chemicals were present only in TN1.Further,11 volatile chemicals were screened for functional verification.The Y-type results showed that linalool at low concentration(2 μL/mL),β-sesquahydralene at high concentration(200 μL/mL),and methyl salicylate had significant repellent effects on the brown planthopper.D-limonene,β-caryophyllene,2-heptanone at high concentration,2-ethyl-benzenamine,and 2,6,10,14-tetramethyl-pentadecane showed significant attractant effects on the brown planthopper.The results of this study are of significance for the development of repellents or attractants for the green control and integrated pest management of the brown planthopper.关键词
