1. As an indicator of the activity of plant-sap ingestion, ^<14>C intake of adults and nymphs from ^<14>C-labelled rice seedlings was examined in Nilaparvata lugens. 2. Relative values for ^<14>C intake of macropterous and brachypterous males and females, and 5th-instar nymphs were 1.00, 1.80, 2.47, 2.64, and 6.01, respectively. 3. There was no quantitative difference in ^<14>C ingested by macropterous females between the preovipositional and ovipositional periods. 4. The degree of ^<14>C ingestion was closely correlated to the body weight and water content of adults. Fifth-instar nymphs ingested the largest amount of ^<14>C despite their lighter body weights. This work was carried out at the Research Institute for Food Science, Kyoto University, at Uzi during the tenure of a fellowship from the Ministry of Agriculture & Forestry, Japanese Government, November 1970 to March 1971. The author wishes to express his sincere gratitude to Prof. Z. Kasai who permitted him to study at his laboratory of the Research Institute for Food Science and to Dr. K. Asada who gave him many helpful discussions and suggestions during this work. He was indebted to Mr. M. Takahashi for technical assistance.
