This paper deals with the observation of behavior of cabbage butterfly larvae in food preference test and food selection test, isolation of mustard oil from cabbage and radish, and especially of the analysis of the mechanism of food preference. The results are summarized as follows: 1) According to observation of behavior in food preference, it is likely that the larvae find out a specific host plant leaf by biting response. 2) It is highly probable that the chemical stimuli (odors) of the food plants are more or less partaken in the final orientation to the host plants. 3) Allyl mustard oil was isolated from cabbage leaves by paper chromatography, which was common to several cabbage races, and moreover some races contained another one or two kinds of mustard oil in extramely small amount. Mustard oil of a different kind was obtained from the leaves of all radish races, and moreover some races contained another one or two kinds of mustard oil in very small amount. The larvae showed no conspicuous tendencies in food preference among various races of cabbage of radish. Based on these facts, it willbe assumed that the mustard oil glucosides are important factor for inducing biting response to and for continuing feeding of, prefered food plants of the cabbage butterfly larvae.
