[Variations in the permeability of the testicular follicle of Locusta migratoria migratorioides (Orthoptera) during the last larval instar].
Variations of the testicular permeability are demonstrated in Locusta migratoria by using tracers such as iron-containing particles of protein. The testicular region containing spermatids is never penetrated by the tracers in contrast to the apical region containing gonia and young spermatocytes. Permeability of this compartment shows variations during the intermoult.
