Influence of Transgenic (Bt) Cotton on the Productivity of Various Cotton-Based Cropping Systems in Pakistan

Agriculture, 2023
Cotton (Gossypium hirsutum L.) is an important fiber crop in Pakistan with significant economic importance. Transgenic, insect-resistant cotton (carrying a gene from Bacillus thuringiensis (Bt)) was inducted in the cotton-based cropping systems of ...

Effects of transgenic Bacillus thuringiensis cotton on insecticide use, heliothine counts, plant damage, and cotton yield: A meta-analysis, 1996-2015. [PDF]

PLoS ONE, 2018
The primary management tactic for lepidopteran pests of cotton in the United States of America (USA) is the use of transgenic cotton that produces Bacillus thuringiensis Berliner (Bt) toxins.

Effect of pyramiding Bt and CpTI genes on resistance of cotton to Helicoverpa armigera (Lepidoptera: Noctuidae) under laboratory and field conditions [PDF]

, 2011
Transgenic cotton (Gossypium hirsutum L.) varieties, adapted to China, have been bred that express two genes for resistance to insects. the Cry1Ac gene from Bacillus thuringiensis (Berliner) (Bt), and a trypsin inhibitor gene from cowpea (CpTI ...

Impact of Bt-cotton on soil microbiological and biochemical attributes

Plant Production Science, 2016
Transgenic Bt-cotton produces Bt-toxins (Cry proteins) which may accumulate and persist in soil due to their binding ability on soil components. In the present study, the potential impacts of Bt- and non-Bt genotypes of cotton on soil microbial activity,

Evaluation of the effect of transgenic Bt cotton on snails Bradybaena (Acusta) ravida and Bradybaena similaris (Ferussac)

Ecotoxicology and Environmental Safety, 2021
The impact of transgenic crops on non-target organisms is a key aspect of environmental safety assessment to transgenic crops. In the present study, we fed two snail species, Bradybaena (Acusta) ravida (B.
