Impacts of Bt transgenic cotton on integrated pest management.
Transgenic cotton that produced one or more insecticidal proteins of Bacillus thuringiensis (Bt) was planted on over 15 million hectares in 11 countries in 2009 and has contributed to a reduction of over 140 million kilograms of insecticide active ingredient between 1996 and 2008. As a highly selective form of host plant resistance, Bt cotton effectively controls a number of key lepidopteran pe...
متن کاملGlobal Impact of Insect-Resistant (Bt) Cotton
Insect-resistant cotton was first introduced commercially in 1996. It is commonly referred to as Bt cotton, because it produces an insecticidal protein from the naturally occurring soil bacterium Bacillus thuringiensis (Bt). Global adoption of Bt cotton has risen dramatically from 800,000 hectares in its year of introduction in 1996 to 5.7 million hectares (alone and stacked with herbicide-tole...
متن کاملHybridizing transgenic Bt cotton with non-Bt cotton counters resistance in pink bollworm.
Extensive cultivation of crops genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) has suppressed some major pests, reduced insecticide sprays, enhanced pest control by natural enemies, and increased grower profits. However, these benefits are being eroded by evolution of resistance in pests. We report a strategy for combating resistance by cro...
متن کاملNext‐generation transgenic cotton: pyramiding RNAi and Bt counters insect resistance
Transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) are extensively cultivated worldwide. To counter rapidly increasing pest resistance to crops that produce single Bt toxins, transgenic plant 'pyramids' producing two or more Bt toxins that kill the same pest have been widely adopted. However, cross-resistance and antagonism between Bt toxins limit th...
متن کاملBrazilian free-tailed bats as insect pest regulators in transgenic and conventional cotton crops.
During the past 12000 years agricultural systems have transitioned from natural habitats to conventional agricultural regions and recently to large areas of genetically engineered (GE) croplands. This GE revolution occurred for cotton in a span of slightly more than a decade during which a switch occurred in major cotton production areas from growing 100% conventional cotton to an environment i...
