Variations in the rate of parasitism of the aphid by A. urticae in different biotopes at a given time are shown in tables, and attention is drawn to the different levels of parasitism observed in apterous and alate individuals. This is discussed in relation to the numbers of alate migrants that may be produced on foxglove at the time the potato plants are sprouting. Temperature appears to exert an important influence in this respect.
