Tritrophic Effects in Bt Cotton
Bulletin of Science, Technology & Society, 2005Transgenic insecticidal Bt crops are being increasingly used worldwide, and concern is increasing about resistance and their effects on nontarget organisms. The toxin acts as a weak pesticide and, hence, the effects are subtler than those of chemical biocides.

Certainty Equivalent Farm Returns from Bt and Non-Bt Cotton
2006Annual mean returns and certainty equivalent returns for 1983-2003 were calculated for specified non-Bt cotton (refuge) percentages for a cotton farm of average size in the Mississippi Delta. Certainty equivalents indicate sprays influence mean profits more than the percentage of refuge in a cotton producer's portfolio.

Rationalising Bt Technology: Creating a Biopolitical Space Around Bt Cotton
History and Sociology of South Asia, 2012Sociologists have long recognised rationalisation as a process through which a universally applicable technical code crystallises as technological rationality of a modern society. This article challenges such essentialist theories that offer deter-ministic and universal generalisations about such abstract categories as technical rationality. Rather it

[Bt toxin distribution in transgenic Bt cotton and soil system].
Ying yong sheng tai xue bao = The journal of applied ecology, 2007This study showed that the amounts of Bt toxin expressed in transgenic Bt cotton leaves and stems (103.5 - 134.1 ng x g(-1)) were rather higher than those expressed in transgenic Bt cotton roots (44.7 - 21.2 ng x g(-1)), indicating that total amount of soil Bt toxin introduced by transgenic Bt cotton could be decreased through treating its above-ground
