Therecommendations generally narrow down to a thorough clear-ing up in winter to destroy as far as may be the hibernatingadults. When the migrations commence from wheat to corn,protection may often be obtained by trenching. The insectsdo not readily resort to flight even when adult, but rather marchfrom field to field, and, by interposing a trench which is noteasily crossed, and where the insects can be destroyed by meansof tar or kerosene, fields may be protected.
