| Abstract: | Simulation of some consequences of invasion of a Bt-resistant insect pest into an agricultural eco-system containing a Bt crop shows that such invasion alters the plant biomass dynamics, decreases the crop yield, and impairs yield predictability. The yield is poorly predictable in a small region of parameter values, which depends on the duration of the insect reproductive period relative to the crop-growing season. |
