Resilin in the cuticle of physogastric queen termites

Summary Resilin is present in the endocuticle of the flexible abdominal intersegmental cuticle of the, physogastric queen of the termite,Odontotermes obesus (Rambur). Resilin seems to assist in the extension of abdomen of the queen termites during physogastry.Acknowledgments. I am grateful to Dr S. O. Anderson for examining the cuticle in the fluorescent microscope. I thank Prof. R. G. Michael for interest in this work, Prof. P. S. Ramakrishnan for providing UV Lamp (Toshnival) for the examination of chromatograms and Mr Sudip Dey for valuable discussions.Previously called A. Sannasi.
