Abstract: | The first anatomical study on aphids was carried out by Antonio van Leeuwenhoek (1696). Among those that carried out numerous dissections on aphids for to clarify some anatomical aspects we mention: Buckton, 1876; Mordvilko, 1895; Snodgrass, 1935; Börner, 1938, 1949, 1952; Svanvici, 1949; Ponsen, 1972; Dixon, 1975; Kunkel & Kloft, 1977, etc. The largest study of the kind was made by Roberti in 1946. He presented the morphology, the anatomy and the histology at Aphis frangulae Kalt. The illustration is done through black and white drawings. Ponsen (1987) presented the anatomy and physiology of the alimentary tract at some aphids.
Anatomically, aphids have very complicated organization if we consider the systematic position of these species.
By series of cross and longitudinal sections we managed to distinguish histo-anatomical elements that belong to the digestive apparatus, muscle, nervous, respiratory, glandular and reproduction systems and also of some structures like: dorsal vessel, adipose tissue, etc.
We present in this paper aspects of the nervous system at sexuparae of Myzus persicae Sulz. |
