The halo effect: suppression of pink bollworm on non-Bt cotton by Bt cotton in China. [PDF]
PLoS ONE, 2012 In some previously reported cases, transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt) have suppressed insect pests not only in fields planted with such crops, but also regionally on host plants that do not produce Bt toxins.

Hybridizing transgenic Bt cotton with non-Bt cotton counters resistance in pink bollworm. [PDF]
Proc Natl Acad Sci U S A, 2017 Significance Crops genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) kill some major pests and reduce use of insecticide sprays. However, evolution of pest resistance to Bt proteins decreases these benefits.

Modeling the evolution of resistance in cotton bollworm to concurrently planted Bt cotton and Bt maize in China [PDF]
Ecological Modelling, 2021 Abstract BackgroundTransgenic maize expressing toxins derived from the bacterium Bacillus thuringiensis (Bt) may be commercially planted in northern China where Bt cotton has been planted for more than two decades. While Bt maize brings additional benefits for insect control, it complicates the resistance management of cotton bollworm (CBW ...

Effects of Soil Salinity on the Expression of Bt Toxin (Cry1Ac) and the Control Efficiency of Helicoverpa armigera in Field-Grown Transgenic Bt Cotton. [PDF]
PLoS ONE, 2017 An increasing area of transgenic Bacillus thuringiensis (Bt) cotton is being planted in saline-alkaline soil in China. The Bt protein level in transgenic cotton plants and its control efficiency can be affected by abiotic stress, including high ...

Diminishing returns from increased percent Bt cotton: the case of pink bollworm. [PDF]
PLoS ONE, 2013 Regional suppression of pests by transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt) has been reported in several cropping systems, but little is known about the functional relationship between the ultimate pest population ...

Fitness of Bt-resistant cabbage loopers on Bt cotton plants. [PDF]
Plant Biotechnol J, 2017 SummaryDevelopment of resistance to the insecticidal toxins from Bacillus thuringiensis (Bt) in insects is the major threat to the continued success of transgenic Bt crops in agriculture. The fitness of Bt‐resistant insects on Bt and non‐Bt plants is a key parameter that determines the development of Bt resistance in insect populations.

Early warning of cotton bollworm resistance associated with intensive planting of Bt cotton in China. [PDF]
PLoS ONE, 2011 Transgenic crops producing Bacillus thuringiensis (Bt) toxins kill some key insect pests, but evolution of resistance by pests can reduce their efficacy.
