A field study was conducted to determine the effects on black swallowtails and monarch butterflies exposed to event 176 pollen. Growth rates of black swallowtail larvae were significantly reduced, likely caused by exposure to event 176 pollen.
The registration of hybrids derived from event 176 will terminate in 2001. As a result, there should be a significant reduction in risk to monarchs and black swallowtail larvae. However, additional studies are needed to examine the impact of Bt11 and Mon810 pollen to black swallowtail larvae.
