Abstract	and endocrine differences between diapausing and non-diapausing larvae of the pine caterpillar Dendrolimus tabulaeformis (Lepidoptera: Lasiocampidae). Zoological Studies 47(1): xx-xx. We investigated chemical and morphological differences between diapausing and non-diapausing larvae of the pine caterpillar, Dendrolimus tabulaeformis (Lepidoptera: Lasiocampidae). Chemical analyses showed that both the lipid content in the whole body and the concentration of trehalose significantly differed between diapausing and non-diapausing larvae. The lipid, protein, and amino acid contents of the hemolymph of diapausing larvae were higher than those of non-diapausing larvae. The content of free fatty acids of non-diapausing larvae was 4 times higher than that of diapausing larvae. Moreover, diapausing larvae showed lower oxygen consumption than non-diapausing larvae. Differences in the anatomy of incretions according to the physiological condition (diapausing or non-diapausing) were evident, and included the number of cells in the corpora allata, the volume of the nucleus, and the internal structure of the cytoplasm. The prothoracic glands also differed between diapausing and non-diapausing larvae. These result suggest that the pine caterpillars hormonally regulate their body composition to adapt to their surroundings.
