Abstract
The concentration of K +, Na +, and Ca 2+ ions in the haemolymph of Periplaneta americana is compared for insects fed on different diets. The Na +/K + ratio is the same when the insect is fed on milk powder or wheat flour; it is lower on a diet of lettuce, the sodium ion concentration decreasing and potassium increasing. The activity of insects fed on milk powder is greater than that of the insects fed on lettuce. This result can be interpreted as being due to modifications in the potassium ion concentration of the haemolymph.
