In order to investigate the causes of insect resistance in rice varieties, feeding habits and honeydew components of Nephotettix cincticeps (Uhl.) were compared for 1 susceptible and 3 resistant varieties in the laboratory in Japan. The pest excreted as much honeydew on resistant varieties as on the susceptible one. The honeydew derived from the resistant varieties contained a small amount of sugars, whereas that from the susceptible one contained 0.36% of sugars as glucose which was composed of 4 kinds of sugars. The results suggested that the leafhopper was unable to suck the phloem sap of resistant varieties. Stylet sheaths were terminated both in xylem and in sieve tubes on resistant varieties.
