Anthropogenic impacts increasingly drive ecological and evolutionary processes at many
spatio‐temporal scales, demanding greater capacity to predict and manage their …

Widespread adoption of Bt crops and persistence of Bt toxins expressed in transgenic plants
could cause rapid evolution of resistance in pests and lead to the loss of the intrinsic …

The major lepidopteran insect pests of cotton and maize harbor intra-specific variation for
behavior determining the selection of host plants for oviposition. Yet, the consequences of …

We describe a simple deterministic theoretical framework for analysing the gene frequency
evolution of two alternative alleles at a single genetic locus in a habitat comprising two …

The evolution of resistance against pesticides is an important problem of modern agriculture.
The high-dose/refuge strategy, which divides the landscape into treated and nontreated …

Traditionally, research concerning insect resistance management (IRM) has emphasized the
targeted pest species and the toxin or toxic plant that it may evolve resistance to. Two other …

Toxic plants have been used for years in agriculture to control major crop pests. However,
the continuous exposure of targeted pests to toxins dramatically increases the rate of …

We describe and analyze a 'screened refuge'technique for indefinitely sustaining control of
insect pests using transgenic pesticidal crops or an applied pesticide, even when resistance …

In two models of pest control using a pesticidal crop along with a non-pesticidal refuge to
prevent the development of resistance, we numerically compute the bifurcations that bound …

We are modeling two insect populations which have a prey and predator relationship. If it is
not controlled the prey can destroy agricultural fields. To prevent the outbreak of the prey …
