Abstract: Fall sampling for secondary soil insects on corn has become important to corn growers who plan on using seed-applied insecticides for these pests. This relatively new seed-applied insecticide technology requires that growers order this technology at the same time they place their seed orders, which is usually done in late fall or early winter. Consequently, the information gained from standard pre-plant sampling methods typically done two weeks before spring planting is too late to be useful. In fall 2005 and 2006, a standard soil sampling method and a more efficient sampling method we developed for detecting annual white grubs were compared in fifteen fields in eastern Virginia. The results indicated no significant difference in numbers of annual white grubs detected between the two sampling methods.
