Extract

The larva of the wheat stem sawfly, Cephus cinctus Nort., lives inside the host stem, cuts it off at ground level in late summer, and spends the winter inside the stub below ground level. This insect can be controlled by the use of resistant spring wheats such as Rescue and Golden Ball. The possibility of the existence of a strain of C. cinctus to which these varieties are not resistant is of major importance.

Platt, Farstad, and Callenbach (1948) found that the average percentages of Rescue stems cut by C. cinctus for five years were 36 at Regina, Saskatchewan, and two at Lethbridge. They suggested that this difference may have resulted from the effects of the environments in two areas, or from genetic variations between the sawflies at the two stations.
