The purpose of this study was to evaluate the possible detrimental impacts of YieldGard corn on select non-target phytophagous and beneficial arthopods. These tests were conducted in the summers of 2001 and 2002 to compare the populations of these arthropods in Bt corn versus non-Bt corn. Preliminary results indicate little noticeable effects.
