An ultrastructural study of Malpighian tubules of the stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae): Cell types and structural zonation
Published online by Cambridge University Press: 19 September 2011
Abstract
The stable fly, Stomoxys calcitrans L., has two pairs of Malpighian tubules. Ultrastructurally, the tubules consist of three morphologically distinct zones: the distal, intermediate and proximal regions, which themselves are characterized by distinct cell types. The tubule cells have numerous mitochondria, microvilli and basal infoldings, which are associated with mitochondria. It is suggested that the distal and intermediate regions are secretory, while the proximal region is reabsorptive; and that the haemotophagous habit in S. calcitrans is probably correlated with the ultrastructure of its Malpighian tubules.
Résumé
La mouche d'estable, Stomoxys calcitrans L., posside deux poires de tubes de Malpighi. L'ultrastructure montre que les tubes ont 3 zones morphologiquement differents; la region-distale, l'intermediaire et la proximale. Les zones sont characterisees par de types de cellules differentes. Les cellules des tubes out des nombreuses mitochondries, des microvilli et des plis basaux qui sont associes aux mitochondries. Il a ete demontre que la region distale et la region intermediare ont un role de secretion, et que la proximale joue un role de reabsorption. L'latitude hematophage de S. calcitrans est probablement corretee avec l'ultrastructure de ses tubes de Malpighi.
