The Biomagnetic Effects on Pupation of Diapausing European Corn Borer, Ostrinia nubilalis (Hubn)

Abstract

Diapausing larvae of the European corn borer were exposed to a magnetic field for varying lengths of time. In three sets of experiments the time required for pupation to occur was lengthened in the treated groups indicating an inhibition of development. In a fourth group, time to pupation was reduced indicating a stimulation to development. It is believed that the type and magnitude of magnetic effects depends largely on the physiological and metabolic state of the organism.
