DEVELOPMENT OF FIELD AND LABORATORY TECHNIQUES TO EVALUATE THE RELATIVE ATTRACTIVENESS OF CORN PLANTS TO CORN ROOTWORM BEETLES (DIABROTICA)

TL;DRAbstract

Studies were conducted to: (1) develop field and laboratory procedures and techniques for use in evaluating the relative attractiveness of inbred lines of corn to western corn rootworm beetles (Diabrotica virgifera virgifera LeConte); (2) compare the relative attractiveness of extracts prepared from specific plant parts (stalk, pollen, silk and leaf) of selected inbred lines of corn to western corn rootworm beetles; and (3) compare the relative attractiveness of selected inbred lines of corn to western corn rootworm beetles and to a lesser extent, northern corn rootworm beetles (Diabrotica barberi Smith and Lawrence). Beetle counts were used to provide data on the relative attractiveness of selected inbred lines of corn to corn rootworm beetles. The effectiveness of the beetle count method was compared to an Immigration-Planting technique in which sticky traps were used to sample corn rootworm populations immigrating into plantings of selected inbred lines of corn. The Immigration-Plan
