Pros and cons of GM crops as a source of resistance to insect pests

Professor Helmut van Emden
Summary Current experience of the pros and cons of using GM crops for resistance to insect pests is largely limited to one source of transgene, the proteins expressing the toxin of Bacillus thuringiensis. Since the gene transferred, and not the method of transfer, is relevant to the topic of this paper, we can explore what is known from plants traditionally bred for insect-resistance based on similar mechanisms to those likely to be used in GM crops, i.e. on single toxins giving a high …
