Many homopteran insects feed on plant sap which contains solutes in very low concentration. Their digestive tract presents a complex called the "filter chamber" where the excess dietary water is believed to flow directly from the initial part of the midgut to the terminal part of the midgut and the proximal regions of the Malpighian tubules. Freeze-fracture experiments carried out on the filter chamber of Cicadella viridis revealed the presence of intramembrane particles on the whole surface of… CONTINUE READING
