Resumo

Haemolymph from the Essig's Lupine aphid, Macrosiphum albifrons (Essig), was analyzed for pH, osmolality, and concentrations of magnesium, calcium, potassium, sodium, chloride, phosphate and citrate. The concentration of inorganic ions and citrate was relatively low forming only 14% of the osmotic potential of the plasma (476 mOsm). The composition of the plasma resembled more the composition of phytophagous Endopterygota than Exopterygota.
