Structural cuticular proteins in termite queens.
The abdominal cuticle from queens of two termite species, Cubitermes fungifaber and Macrotermes bellicosus, has been investigated with respect to changes occurring during development of physogastry. The following properties have been determined: 1. Relative content of protein and chitin and the percentage of easily extracted protein. 2. Number of proteins separated by electrophoresis and their molecular weights. 3. Amino acid compositions of the intertergal and pleural membranes and of the neosclerites in M. bellicosus. The intertergal and pleural membranes appear to be typical "soft" cuticles, and the neosclerites must also be considered "soft" cuticles, although they are rather rigid.
