In the irradiation of Melanoplus differentialis eggs, the entire spectrum of a quartz mercury vapor arc was utilized with the energy input and the distance from the lamp to the eggs kept constant. The dosages were controlled by varying the length of exposure. The eggs were irradiated on moist paper, under quartz plates and at constant temperature. Oxygen consumption and percentage of hatching was determined.
