Title The trends and future of biotechnology crops for insect
pest control

Description 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 increasing
numbers of countries over the past 14 years. This review discusses the current status of insect
resistant transgenic crops and the often raised concern that its resilience is limited and that its efficacy
will be compromised by insect resistance. We consider this trait as it is currently deployed in fields
across the world as well as potential candidates that are at various stages of development along the
pathway between the laboratory and deregulation. Future trends and prospects for biotechnological
applications to mediate crop protection against insects are also considered. These include strategies
employing stacked genes, modified Bt toxins, vegetative insecticidal proteins, lectins, endogenous
resistance mechanisms as well as novel approaches. In addition, the benefits and risks associated with
the adoption of GM insect resistant crops, especially for developing countries and resource-poor
smallholder farmers are also discussed.
