Abstract
A cutworm larval bait trap was improved for sampling black cutworm populations in field corn. Trap size was reduced from 1.98 to 0.41 liters without substantially reducing trap efficiency. A removable inner cup was used to reduce the quantity of vermiculite which must be searched for thc retrieval of cutworms. Four trap components used in the original trap were adapted to the modified trap and evaluated. Two of these components, cylinders and wheat bran, had a significant effect on larval capture, whereas metal guides and lids had little or no effect and were not incorporated into the modified trap design.
