摘要
为明确抗褐飞虱水稻品种Mudgo和感褐飞虱水稻品种TN1释放的挥发物中化学组分的差异,筛选鉴定对褐飞虱具有功能效应的活性化合物。本研究通过顶空动态收集装置获取Mudgo和TN1水稻的挥发物,采用气相色谱-质谱联用仪(GC-MS)筛选、鉴定水稻挥发物的活性组分,基于筛选鉴定出的Mudgo与TN1水稻挥发物中的差异活性化合物,采用Y型嗅觉仪对其进行功能验证。本研究在两水稻品种的挥发物中共筛选鉴定到52种化合物,其中Mudgo和TN1分别鉴定到27种,仅在Mudgo挥发物中存在的化合物有10种,仅在TN1挥发物中存在的化合物有15种。基于Mudgo和TN1水稻挥发物的差异活性组分鉴定结果,筛选出11种活性化合物进行功能验证。Y型嗅觉仪测定结果表明:低浓度(2μL/mL)的芳樟醇、高浓度(200μL/mL)的β-倍半水芹烯和水杨酸甲酯这3种化合物对褐飞虱具有显著的驱避作用,可发展用于褐飞虱防治的驱避剂;D-柠檬烯、β-石竹烯和高浓度的2-庚酮、2-乙基苯胺和姥鲛烷这5种化合物对褐飞虱具有显著的引诱作用,可发展用于褐飞虱防治的引诱剂。该研究可为褐飞虱的绿色防控和害虫综合治理提供科学数据和理论依据。
The difference of chemical components of rice volatiles released by the resistant variety Mudgo and the susceptible variety TN1 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(2μL/mL),β-sesquahydralene at high concentration(200μL/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.
