True white grubs may cause early-season stand reduction in corn. Because the past winter was extremely mild, survival of many soil dwelling insects may be much higher than during an average or colder-than-average winter. As with most soil insects, it is difficult to predict when and where true white grubs will be found. Problems can be expected in cornfields following pasture or grassy Conservation Reserve Program ground.
