Pure Bt-crop and mixed seed sowing strategies for optimal economic profit in the face of pest resistance to pesticides and Bt-corn

作者：

Highlights：

• We developed a discrete pest growth model with evolution of Bt-corn resistance.

• The net present value with pure Bt-corn or mixed planting strategy is investigated.

• The effects of parameters on the net present values are studied.

• The optimal proportion of the field planted with non-Bt-corn has been discussed.
