Two studies were conducted over three years to evaluate popcorn as a potential refuge for western, Diabrotica virgifera virgifera LeConte, and northern, Diabrotica barberi Smith and Lawrence, corn rootworms. Objectives of these studies were to determine if popcorn can influence corn rootworm distribution and to determine if corn rootworm emergence rates and total beetle emergence from popcorn and field-corn plots are similar. Two varieties of popcorn (105-d and 118-d), one mixture of popcorn (50%: 105-d and 118-d), and field corn (108-d) were evaluated. Significantly higher numbers of western and northern corn rootworm adults were captured from popcorn plots in 2000 and 2002. Adult corn rootworm captures were not significantly different from popcorn and field-corn plots during 2001. Beetle emergence was evaluated from 20 plots of popcorn and field corn with various treatment combinations. Emergence rates and total beetle emergence from popcorn plots tended to be lower than from field-corn plots. Popcorn influences adult corn rootworm distribution, however, compared to field corn popcorn produces fewer beetles.
