Genetically modified (GM) plants are the center of an increasingly rancorous debate about the value of agricultural biotechnology. The champions of agricultural biotechnology see it as a tool to help solve problems related to hunger and excessive pesticide use (BIO 2001). The critics of biotechnolog...
The main fear among farmers is that Bt cotton contained the terminator gene, which means that the plants are genetically engineered to render seeds sterile. As of January 2004, Bt cotton occupies about 7 million hectares accounting for 20 percent share of the world-cultivated cotton.Natarajan, K...

Larval lesser armyworm Spodoptere exigua (Hubner) were separately fed with Bt trans-genic cotton (Bt cotton in short) and other five kinds of plants, the changes of their development and insecticide susceptibilities were compared, and the activities of acetylcholinesterase and carboxylesterase of thei...
Indonesia is perhaps the only country that has given a resounding slap on the face of biotech industry. They uprooted all the Bt Cotton plants grown in the Sulawesi region, burnt them and sent Monsanto packing home. The $700,000 bribe offered by Monsanto to local authorities to permit them ...
For example, some evidence suggests small changes in abundance do not impact biological control function in Bt cotton [75]. That is, even if statistical differences in experimental studies and meta-analyses are observed, how are such differences linked to ecosystem functions and can they lead to ...
The risk effects of the technology are likely very important to smallholder farmers in the developing world due to their risk-aversion. We advance the emergent literature on Bt-cotton and production risk by using panel data methods to control for possible endogeneity of Bt-adoption. We estimate ...
Using Resistant Prey Demonstrates That Bt Plants Producing Cry1Ac, Cry2Ab, and Cry1F Have No Negative Effects on Geocoris punctipes and Orius insidiosus Geocoris punctipes (Say) and Orius insidiosus (Say) are generalist predators found in a wide range of crops, including cotton (Gossypium...
Regarding Bt cotton, correct statements are: A. Bt enters the midgut of the pest by making pores in the epithelium. B. Bt produces cryl Bt protein toxin in the Bt cotton plants C. Toxin protein genes of Bt are present in the genome of Bt cotton plants ...
Several laboratory studies have provoked widespread concern that Bt plants can harm non-target insects.A laboratory study was performed to investigate whether growth of Hylyphantes graminicola and Coleosoma octomaculatum as well as predation behavior of H.garminicola were affected by Bt cotton.Larvae...
