A pictorial representation of the gut of the green peach aphid, Myzus persicae (Sulzer), is shown based on dissection, light microscopy, and electron microscopy.
The sucking pump is crescentic in cross section with a thick, rigid, posterior wall and a thinner, flexible, anterior wall. Dilator muscles arise on the clypeus and are inserted along the midline of the anterior wall of the pump chamber. Morphologicael evidence of the sucking action of the pump is included.
