In a previous paper (Takata, '59, '61) the author pointed out that there was some difference in the tendency of food preference between the larvae from different localities, assuming that the difference in the degree of cultivation of the host plants is one of the causes inducing the variation of food preferenceof common cabbage butterfly larvae. The present paper deals with the demonstration of the above assumption. Table 1 shows tendencies of Iwaoka strain. From this table, it proves that the larvae reared with cabbage prefers decidedly cabbageleaves to radish leaves, and the larvae reared with radish prefers radish leaves to cabbage leaves. The tendency is more conspicuous in the former. At Iwaoka the cabbage is cultivated far more frequently than the radish and other cruciferous plants (Fig.1). Noroyama strain shows the opposite tendency (Table 2), and atNoroyama the radish is cultivated far more frequently and in larger area than the cabbage (fig.2). Table 3 shows tendencies of Maruyama strain. The larvae reared with cabbage or radish show not so much conspicuous tendency in preference asmentioned above. At Maruyama the cultivation of cultivation of cruciferous vagetables is not active. In consequence, it seems that the food preterence is affected by the degree of cultivation of the host plants. This conclusion supports the previous reports ('59, '61).
