Now, two new studies using more exacting methods found that Bt crops have no negative effects on two beneficial insect predators or on a beneficial entomopathogenic nematode.
In an article in the February issue of Environmental Entomology, researchers used caterpillars that were known to be resistant to Bt proteins and fed them Bt maize and Bt cotton…
