Abstract
The interactions between plants, pest insects and beneficial parasitoids can be impacted in unintended ways by transgenic insect-resistant crops. Insertion of genetic material can result in altered expression which compromises the original defence responses of the host, or the normal tritrophic interactions between plant, pest and parasitoids, changing the competitiveness of the plant. The engineered characteristic can also lead to changes in the population genetics of pests as a result of selection for strains not susceptible to the toxic compound. Using transgenic wheat and oilseed rape as host crops, the potential of transgenic technology unintentionally to produce either superplants or superpests will be investigated.
