Abstract for Dr. Ringland's Talk

Nurturing with ulterior motives:  the use of refuges in agricultural pest control
Dr. John Ringland

When nonlinear dynamical processes occur in a heterogeneous environment, complexity and surprises are often in store.
A case in point is in the reproduction and survival of an agricultural pest species in a habitat consisting mainly of crops that have been made strongly pesticidal by genetic engineering, but partly of benign "refuges" for the pests.
I will show how nurturing pests can actually be an effective means of controlling them, but that there are balancing acts involved. If we get it right, the greatly feared development of pesticide resistance in the pest population can be not only delayed but prevented indefinitely. If we get it wrong, we can actually ignite this process we are trying to prevent.
