The trends and future of biotechnology crops for insectpest control uri icon

abstract

  • Biotech crops, including those that are genetically modified (GM) with Bacillus thuringiensis (Bt)endotoxins for insect resistance, have been cultivated commercially and adopted in steadily increasingnumbers of countries over the past 14 years. This review discusses the current status of insectresistant transgenic crops and the often raised concern that its resilience is limited and that its efficacywill be compromised by insect resistance. We consider this trait as it is currently deployed in fieldsacross the world as well as potential candidates that are at various stages of development along thepathway between the laboratory and deregulation. Future trends and prospects for biotechnologicalapplications to mediate crop protection against insects are also considered. These include strategiesemploying stacked genes, modified Bt toxins, vegetative insecticidal proteins, lectins, endogenousresistance mechanisms as well as novel approaches. In addition, the benefits and risks associated withthe adoption of GM insect resistant crops, especially for developing countries and resource-poorsmallholder farmers are also discussed
