High myo-inositol concentration in the hemolymph of planthoppers

High myo-inositol concentration in the hemolymph of planthoppers

Applied Entomology and Zoology ust; 38(3): 359-364

Myo-inositol was found in the hemolymph of three species of rice planthoppers, Nilaparvata lugens, Laodelphax striatellus Sogatella furcifera, along with the major common components by 1H-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 13C-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.
