Abstract/OtherAbstract:
Regions of the fat body of larvae of Chaetophyes compacta and Pectinariophyes sp. (Machaerotidae, Homoptera) which are closely associated with mycetomes have been analysed by electron probe X-ray microanalysis. It is shown that cells in these regions contain electron probe X-ray microanalysis. It is shown that cells in these regions contain electron dense granules which are rich in copper and sulphur. These two elements occur in the atomic ratio of 3:2 respectively. It is conjectured that copper may be bound to a sulphur containing metallothionein and that the granules represent either the end products of copper detoxification or serve as copper stores for synthesis of enzymes and macromolecules by the mycetomal symbionts.
