Abstract

The changes with age in the ultrastructure of the fat body in female Sitophilus granarius are described. The fat body is much reduced in the aged animal. Ageing causes extensive ultrastructural changes in the cell organelles of the fat body cells including an increase in adi electronic lysosome- like bodies, autophagic vacuoles and lipid droplets, together with a decrease in glycogen particles. Many of the mitochondria have electron- translucent matrices. The changes observed are discussed in relation to prevent observations on other insect species.
