• Eggs and larve of D. spectabilis were artificially placed on pine trees and their survival was observed at two experimental stations, Momoyama and Sumiyoshiyama, in Kyoto. At Momoyama natural infestation by this insect was seen. At Sumiyoshiyama no natural population occurred. At Momoyama about 0.9% of the eggs released emerged as adults. During the late larval instars the mortality was caused by some density-dependent factors. Predation by Polistes japonica and dispersal were noticed as these factors. At Sumiyoshiyama the population, placed artificially by the experimentor, died out on the larval stage. In spite of the final extermination of the population, some density dependence was suggested by the different rates of mortality between high-and low-density populations. Only the predation by ants and mantises on hatching larvae was observed as mortality factors. These were observed only when the density was high.
