Delaying insect resistance to transgenic crops.
I n her seminal work, Silent Spring, Rachel Carson writes: ‘‘If Darwin were alive today the insect world would delight and astound him with its impressive verification of his theories of survival of the fittest. Under the stress of intensive chemical spraying the weaker members of the insect populations are being weeded out.’’ (1) Evolution of insecticide resistance in 400 species of insects no...
متن کاملConsiderations on the Use of Transgenic Crops for Insect Control
The adoption of agricultural technologies, whether developed through biotechnology or other methods, depends on social, political, regulatory and biological parameters. This article first presents an example of a low-input, non-biotechnological method of pest control that, while seemingly reasonable to researchers and extension agents, was not adopted by farmers. It then analyses a method for i...
متن کاملInsect-resistant biotech crops and their impacts on beneficial arthropods.
With a projected population of 10 billion by 2050, an immediate priority for agriculture is to achieve increased crop yields in a sustainable and cost-effective way. The concept of using a transgenic approach was realized in the mid-1990s with the commercial introduction of genetically modified (GM) crops. By 2010, the global value of the seed alone was US $11.2 billion, with commercial biotech...
متن کاملPlant fitness assessment for wild relatives of insect resistant crops.
Risk assessments of new insect-resistant crops will need to estimate the potential for increased weediness of wild crop relatives as a consequence of gene flow. When field experiments are precluded by containment concerns, simulation experiments can identify hazards or measure expected differences between GMOs and parental plants. To measure plant fitness consequences of wild plant protection f...
متن کاملInsect-resistant transgenic plants in a multi-trophic context.
So far, genetic engineering of plants in the context of insect pest control has involved insertion of genes that code for toxins, and may be characterized as the incorporation of biopesticides into classical plant breeding. In the context of pesticide usage in pest control, natural enemies of herbivores have received increasing attention, because carnivorous arthropods are an important componen...
