The Behavior of Isolated Hearts of the Grasshopper, Chortophaga Viridifasciata, and the Moth, Samia Walkeri, in Solutions With Different Concentrations of Sodium, Potassium, Calcium, and Magnesium
Abstract:Insect tissue is able to maintain its activities in very abnormal surrounding media. However, there is an obvious need to determine the exact tolerance of insects to different ions. This information may lead to the formation of an adequate insect physiological solution. It is the purpose of this investigation to determine the tolerance of isolated insect hearts to different concentrations of sodium, potassium, calcium, and magnesium ions, as well as to changes in the osmotic pressure of the surrounding medium.… Show more
