Membranes associated with the disintegration of mycetomal micro-organisms in Sitophilus zea-mais (Mots.) (Coleoptera).
The mycetomal micro-organisms of Sitophilus zea-mais give evidence in electron micrographs of having two peripheral unit membranes, an intermediate layer, intracytoplasmic membranes and DNA-like material. They appear to disintegrate, at times, with the concomitant formation of membrane masses. It is suggested that these are visible with the phasemicroscope and that they are probably myelin figu...
