Abstract :イエシロアリの口腔および肛門から排出された分泌物について検討した。酸加水分解によって, 分泌物は約55%の糖と20%のアミノ酸で構成されていた。ペーパークロマトグラフイにより糖の構成はD-gluculonic acid, ?(Rf 0.32), D-galactose, D-glucose, D-xylose, L-rhamnose, ?(Rf 0.79)がスポット面積比で1 : 1 : 2 : 2 : 1 : 1 : 1であり, アミノ酸の構成はAsparatic acid, L-glutamic acid, Alanine, L-tyrosine, D, E, Gがスポット面積比で1 : 1 : 2 : 2 : 1 : 1 : 1であることを示した。一方嗜好性テストで糖部よりはアミノ酸部に嗜好性を示し, アミノ酸でも, とくにAsparatic acidとL-tyrosineの混合物に強い嗜好性を示した。
The Secreion from the mouth and anus of termites have investigated. On the hydrolysis, the yield of sugars and amino acids were about 55%, and 20% respectively. It was identified by paper chromatogrphy that sugars fraction gave D-glucronic acid, (Rf 0.32) D-galactose, D-glucose, D-xylose, L-rhamnsoe, (Rf 0.79), (1 : 1・2・2 : 2 : 1・1 : 1) and amino acids fraction gave asparatic acid, L-glutamic acid, alanine, L-tyrocine, D, E, G, (1 : 1 : 2 : 2 : 1 : 1 : 1), Besides, on the orientation and aggregation test of termites, it was shown that termites attacked amino acids fraction. In the amino acids, especially, mixture of L-asparatic acid and L-tyrosine shown powerfully to inducet ermites. Acknowledgment-In succession of this study, the author wishs to thank Professor Tamio KONDO, Assistant professor Masasi SUMIMOTO, and Assistant Isako SAEKI, Faculty of Agriculture, Kyushu University for their consistently guidance.
