In a previous paper the author pointed out the possibility that total extends of the district where cultivation of the host plants is carried out exert a profound effect upon the food preference of common cabbage butterfly larvae and cause variations in the tendency of their food preferance. In order to confirm this problem further, the present experiment was planned, using the animals from Kamikoma and Sasayama districts. At Kamikoma the redish is cultivated far more frequently than other cruciferous plants, whereas at Sasayama cruiferous plants containing the redish are cultivated to a lesser amount than at other districts. The results obtained are shown in Tables 1 and 2. The Kamikoma strain reared with radish prefered decidedly radish leaves to cabbage leaves, and the larvae reared with cabbage leaves to radish leaves. On the other hand, the Sasayama strain, whether reared with radish or cabbage, didnot show so much conspicuous tendency in preference as the former. In conclusion, there are some differences in the tendency of food preference of the larvae among different localities, and the local extent of distribution of the host plants seems to be one of the main causes inducing the variation of food preference.
