[Phase morphometric differences among Locusta migratoria cinerascens, Locusta migratoria migratorioides, and their mutant albinos (Orthoptera)].

A first canonical variate analysis (factor analysis) of two geographic strains of L. m. shows that the same axes distinguish crowded from isolated animals as well as their geographical origins. Two other analyses between normal and albino strains of both localities show no differences for one strain; however for the other strain, the pigmentary mutation coincides with a solitary tendency.
