Corn rootworm larva. Recently, we have begun to conduct field research to measure the efficacy of experimental Bt corn hybrids for control of corn rootworms. Although Bt corn hybrids for rootworm control are not yet commercially available, they will be soon. We believe it is imperative for us to have knowledge of the level of effectiveness of Bt corn against corn rootworms before growers begin to plant it. In addition, we have conducted research to determine the potential effects of Bt corn on nontarget organisms.

Also, a research project was initiated in 2000 to collect information regarding pollination periods of corn and occurrence of different life stages of monarch butterflies throughout Illinois. Knowledge of the co-occurrence of corn pollination and monarch life stages is necessary for determination of the potential risk of Bt corn to monarch populations. In the foreseeable future, growers will continue to plant transgenic crops as part of their pest management programs, so we need to know how to manage the technology to make certain that its benefits far outweigh its limitations.
