Insect resistance to pesticides is a major concern in modern agriculture and human health worldwide. I study biological, ecological, genetic, and operational factors that influence resistance evolution, so as to develop innovative resistance management strategies for the sustainable control of insect pests, particularly in transgenic Bacillus thuringiensis (Bt) cotton. Transgenic insecticidal crops are a suitable model for studying micro-evolutionary adaptation of insects. I am particularly interested in how non-Bt host plants may provide efficient refuges for target pests, and how fitness costs can be exploited to develop "active" refuges that select against resistance. Results will address novel and important issues related to the sustainability of transgenic crops in sub-Saharan Africa farming systems, where Bt cotton is expected to expand rapidly.
