Differentiation of mite species by using cellulose acetate and equilibrium polyacrylamide gel electrophoresis of isoenzymes.

The isoenzymes of various species of medically and economically important mites were studied using cellulose acetate and equilibrium polyacrylamide gel electrophoresis. Interspecific differences in isoenzymes were found, which were species-specific. Intraspecific differences in isoenzymes were also found when individual mites were examined. The efficiency of each technique, and their use in various fields of acarology, are discussed. In addition, possible phylogenetic relationships as revealed by these techniques are suggested.
