利用核磁共振氢谱分析了褐飞虱、灰飞虱和白背飞虱3种稻飞虱血淋巴中的肌醇沿着主要共有成分。肌醇浓度比海藻糖浓度高约3至5倍。N.褐飞虱和成虫都含有肌醇。碳-13-核磁共振示踪实验表明，肌醇产生的葡萄糖和积累在血淋巴中的峰值浓度出现晚于海藻糖。讨论了肌醇对稻飞虱的作用。
Myo-inositol was found in the hemolymph of three species of rice planthoppers, Nilaparvata lugens, Laodelphax striatellus and Sogatella furcifera, along with the major common components by H-1-NMR spectroscopy. Myo-inositol concentration was about three to five times higher than trehalose concentration. N. lugens nymphs as well as adults contained myo-inositol. Trace experiments with C-13-NMR spectroscopy showed that myo-inositol was produced from glucose and accumulated in the hemolymph with a peak concentration appearing later than that of trehalose. The role of myo-inositol in rice planthoppers is discussed.
