Effectiveness and chemical pest control of Bt-cotton in the Yangtze River Valley, China

Evolution of Bt cotton production costs and effectiveness  

Simulations based on the observed survival on cotton plants of the three insect types (GA, GA-R and F1) show that the projected rate of resistance evolution is 2 to 4.5 times higher

Specifically, when the concentration of one toxin (here Cry1Ac) declined seasonally, resistance to Bt cotton often occurred rapidly in simula- tions where refuges of non-Bt cotton

By referring to datasets seldom used in earlier analyses, we argue that Bt-cotton use in China has benefitted a lot from the development of the cotton variety market and it

The second corresponds to the development of the variety market, enhanced by the commercial release of Bt-cotton and geared towards the combination of hybrid and Bt traits, leading
