As a small grain pest this bug is neververy bad, but it should nevertheless bedestroyed whenever and wherever this ispossible. Since it breeds on weeds ofvarious kinds in large numbers, clean cul-ture is one of the best preventive meas-ures to be recommended. Large-Eyed Ground-Bug. {Geocorishullata Say) is another of the Chinch-bug-like insects that occasionally occursquite plentifully in grain fields here inthe west. It is shown in the illustrationWhile it is more of a weedinsect than a grain pest, it. Fig. 79. — Large-eyedGround-bug {Geocorisbullata), enlarged.
