• In June and July, 1978,galls of Dryocosmus kuriphilus were dissected to examine the contents of cells composing the galls, and from June to September in the same year, emergence of adult Dryocosmus and its parasites was observed in the laboratory. Growth of Dryocosumus in the cell was even and adult emergence out of the gall took place during a period as short as about 10 days. Frequency distribution of cells composing a gall was approximated using the truncated negative binominal series. Percentage parasitism was variable among trees, although parasitic activity was low in genetal. Emergence of adult parasites lasted for a longer time than that of D. kuriphilus.
