Abstract
Abstract Application of precocene II, either topically or by contact method, to newly emerged adult females of O. fasciatus inhibits egg maturation and induces degeneration of the corpus allatum (CA). Seven days after precocene-treatment the CA were very small. Ultrastructural studies revealed a number of disintegrating nuclei, degenerating mitochondria, lysosome-like bodies and autophagic vacuoles. Fifteen days after precocene treatment the CA showed further reduction in the size and number of cells, and the degenerative changes were much more pronounced. It appears that the effect of prococene on the CA is irreversible.
