The Effects of Precocene II on the Fine Structure of Corpus Allatum in Adult Female Anacridium aegyptium L. (Orthoptera, Acrididae)

Authors: GÜRSEL ERGEN

Abstract: In this study, the effects of the antijuvenile hormone Precocene II on the corpus allatum of adult females of Anacridium aegyptium L. (Orthoptera) were investigated with electron microscopy. In the insects, topically treated with 500 µg precocene II, the corpora allata did not show marked atrophy or destruction. After 10 or 20 days of precocene II treatment, the ultrastructural changes of especially the nuclei, mitochondria, endoplasmic reticulum membranes, Golgi complexes and some other intracellular organelles in the gland cells, probably reflect a moderate sensitivity to this compound.

Keywords: Corpus allatum, Precocene II, Ultrastructure, Anacridium aegyptium.
