TOGASHI, Katsumi & TAKAHASHI, Fumiki (Entomol. Lab., Coll. Agric., Kyoto Univ.) 1977. Preferential feeding of the last instar larvae of Dendrolimus spectabills BUTLER (Lepidoptera : Lasiocampidae), on the old needles of Pinus thunbergii PARL. in the field. Jap.J.Ecol. 27 : 159-162. In the field as well as in the laboratory, the last instar larvae of the pine moth preferred to feed on one-year-old needles of Japanese black pine, which contribute little to the future growth of the tree. The degree of feeding preference of a larva was closely related to the frequency of larval incidence on the twigs of different age classes. The seasonal change in the degree of feeding preference of large larvae was suggested from their distribution on a pine tree in the field. It was not completely consistent with but similar to that of the last instar larvae obtained from the laboratory experiment.
