Economic Benefits of Bt Maize Maize containing a transgenically expressed toxin originating from Bacillus thuringiensis (Bt maize) is planted across the United States to combat insect herbivory. Non-Bt Maize is also planted alongside Bt maize fields to provide refuges for the insects, which helps to prevent resistance to Bt maize from evolving. Hutchison et al. (p. 222; see the Perspective by Tabashnik) analyzed how Bt maize affected the economic impact of the European corn borer moth in the… Expand

Effectiveness of the natural resistance management refuge for Bt-cotton is dominated by local abundance of soybean and maize
TLDR
It is shown refuge effectiveness is responsive to local abundances of maize and cotton and non-Bt soybean, and maize, in its role as a source of H. zea infesting cotton and other hosts, influences refuge effectiveness. Expand
Crop rotation mitigates impacts of corn rootworm resistance to transgenic Bt corn
TLDR
The frequency of corn fields with severe rootworm damage was reduced by rotating corn with other crops and by not planting the same type of Bt corn year after year in the same field, and the effectiveness of corn rotation for mitigating Bt resistance problems did not differ significantly between crop-reporting districts with versus without prevalent rotation-resistant rootworm populations. Expand
Field-evolved resistance by western corn rootworm to multiple Bacillus thuringiensis toxins in transgenic maize
TLDR
It is shown that cross-resistance exists between Cry3Bb1 maize and mCry3A maize and is associated with severe injury to Bt maize in farmers’ fields, illustrating the potential of insects to develop resistance rapidly when Bt crops do not achieve a high dose of Bt toxin. Expand
Field-Evolved Resistance to Bt Maize by Western Corn Rootworm
TLDR
This is the first report of field-evolved resistance to a Bt toxin by the western corn rootworm and by any species of Coleoptera, and suggests that improvements in resistance management and a more integrated approach to the use of Bt crops may be necessary. Expand
Managing maize under pest species competition: Is Bt (Bacillus thuringiensis) maize the solution?
TLDR
A bioeconomic model is developed to analyze the interactions between primary and secondary insect populations and the impact of different management options on insecticide use and economic impact over time and it is suggested that secondary pests could easily become key insect pests requiring additional measures to keep their populations under the economic threshold. Expand
Resistance to Bt corn by western corn rootworm (Coleoptera: Chrysomelidae) in the U.S. corn belt
TLDR
The scientific evidence for D. v. virgifera resistance to Bt rootworm traits and the cropping system practices that have contributed to the first reports of field-evolved resistance to a Bt toxin are examined to emphasize the necessity of an integrated pest management approach to address the issue. Expand
Regional pest suppression associated with widespread Bt maize adoption benefits vegetable growers
TLDR
It is demonstrated that vegetable growers benefit via decreased crop damage and insecticide applications in relation to pest suppression in the Mid-Atlantic United States, and the positive impacts identified here expand on the reported ecological effects of Bt adoption. Expand
Bt maize and integrated pest management--a European perspective.
TLDR
Bt maize is a highly specific tool that efficiently controls the main pests and allows combination with other preventive or responsive measures to solve other agricultural problems including those with secondary pests. Expand
Fitness costs associated with Cry1F resistance in the European corn borer
TLDR
Fitness costs associated with Cry1F resistance in O. nubilalis when insects were reared on three maize lines are examined to contribute to the maintenance of Cry1f susceptibility in field populations more than a decade afterCry1F maize was commercialized. Expand
Climate change, transgenic corn adoption and field-evolved resistance in corn earworm
TLDR
The challenges posed by climate change for Bt biotechnology-based agricultural pest management are highlighted, and the need to incorporate evolutionary processes affected byClimate change into Bt-resistance management programmes is highlighted. Expand

Economic Analysis of Transgenic Maize and Nontransgenic Refuges for Managing European Corn Borer (Lepidoptera: Pyralidae)
We simulated the population dynamics and population genetics of European corn borer, Ostrinia nubilalis (Hubner), and damage to maize in a hypothetical region containing transgenic and nontransgenic… Expand
Biotechnology and the European corn borer: measuring historical farmer perceptions and adoption of transgenic Bt corn as a pest management strategy.
TLDR
After having planted Bt corn and obtained excellent control of European corn borer, most farmers believed that this insect had been causing more yield loss than they previously had suspected in their non-Bt corn. Expand
Suppression of Cotton Bollworm in Multiple Crops in China in Areas with Bt Toxin–Containing Cotton
TLDR
Analysis of the population dynamics of H. armigera from 1992 to 2007 in China indicated that a marked decrease in regional outbreaks of this pest in multiple crops was associated with the planting of Bt cotton, which may reduce its presence on other host crops and the need for insecticide sprays in general. Expand
Long-term regional suppression of pink bollworm by Bacillus thuringiensis cotton
TLDR
It is suggested that long-term regional pest suppression after deployment of Bt crops may also contribute to reducing the need for insecticide sprays. Expand
Managing resistance to Bt crops in a genetically variable insect herbivore, Ostrinia nubilalis.
TLDR
It is found that unstructured (non-corn) refuges contribute more to E race than to Z race populations of ECB in upstate New York (USA), and evidence for reduced fecundity when reared on non-corn hosts all argue against a relaxation of current IRM refuge standards in corn based on alternative-host use. Expand
Efficacy and risk efficiency of sweet corn hybrids expressing a Bacillus thuringiensis toxin for Lepidopteran pest management in the Midwestern US
TLDR
The results suggest that Bt hybrids can provide consistent performance, regardless of the pest complex, pest density, or geographic location in the Midwestern US. Expand
Landscape Effects of Insect-Resistant Genetically Modified Crops
TLDR
Indirect effects of the insect-resistant GM crops on the agricultural ecosystems due to multitrophic exposure, loss of prey, or reduction of prey quality, are generally negligible compared with the direct effects of other more dramatic environmental manipulations that are standard agricultural practices. Expand
Effects of insect population size on evolution of resistance to transgenic crops.
TLDR
Resistance evolution was affected by interactions between carrying capacity, dispersal, and the percentage of fields planted with Bt cotton, which indicates that factors affecting stochastic events can play an important role in the evolution of resistance. Expand
Dispersal of Newly Eclosed European Corn Borer Adults (Lepidoptera: Crambidae) from Corn into Small-Grain Aggregation Plots
TLDR
Examination of influences of pheromone lure, plant density, and plant species on distributions of feral and newly emerged, laboratory-reared O. nubilalis among small-grain aggregation plots found that plant species significantly influenced adult distributions among aggregation plots. Expand
Managing the Evolution of Insect Resistance to Transgenic Plants
TLDR
Computer simulation indicates that a strategy that exploits corn borer preferences and movements can delay the evolution of resistance and reduce insect damage in the untreated fields of a patchwork planting regime. Expand
