Aphids and Bt-tomato

What is it about?

The effects of genetically modified tomato plants expressing the toxin Cry3Bb on the aphid Macrosiphum euphorbiae and some of its natural enemies were assessed under laboratory conditions. No significant differences between performance of the aphid were observed on genetically modified tomato plants with respect to their near-isogenic control line. Similarly, no significant differences were found on the longevity and prey consumption of the predator Macrolophus caliginosus when fed aphids reared on transgenic or control plants. Moreover, the genetic modification did not affect the attractiveness of uninfested tomato plants towards A. ervi.
