Abstract:Phloem or xylem feeding by leafhoppers and planthoppers on susceptible and resistant rice varieties was indicated by the difference in the color of their excreta on seedlings treated with safranine, a dye that is selectively translocated through roots into xylem vessels. Red honeydew of the green leafhopper Nephotettix virescens (Distant) on safranine-treated seedlings of the resistant ASD7 variety indicated that the insect sucked primarily from xylem vessels, whereas clear honeydew excreted on seedlings of the susceptible TN1 variety indicated phloem feeding. Plant hoppers Nilaparvata lugens (Stål) and Sogatella furcivera (Horv´th) were primarily phloem feeders.
