What is Evolutionary Ecology of Insecticide Resistance?

Evolutionary ecology of insecticide resistance examines how fitness costs, migration, and refuge strategies drive resistance allele frequency changes in insect field populations.

This field integrates population genetics models with landscape ecology to predict resistance evolution. Key studies document field-evolved resistance in species like western corn rootworm (Gassmann et al., 2011, 650 citations) and spider mites (Dermauw et al., 2012, 498 citations). Over 300 papers explore these dynamics, emphasizing refuge strategies and non-recessive inheritance.

Key Challenges

Why It Matters

Evolutionary models inform refuge planting policies to delay resistance, as seen in Bt maize failures due to insufficient refuges (Gassmann et al., 2011). These frameworks guide insecticide deployment in agriculture, preserving crop yields against pests like western corn rootworm. Carrière et al. (2010) highlight how understanding migration and fitness costs sustains Bt crop efficacy amid global pest pressures.

Key Research Challenges

Quantifying fitness costs

Fitness costs of resistance alleles vary by environment, complicating model predictions. Steppuhn et al. (2004) show nicotine resistance imposes herbivore performance penalties in nature. Measuring these costs requires field validation beyond lab assays.

Modeling migration effects

Gene flow from migration accelerates resistance spread across landscapes. Carrière et al. (2010) analyze migration's role in Bt crop adaptation. Integrating landscape ecology into population models remains computationally intensive.

Optimizing refuge strategies

Refuge designs must balance resistance delay with farmer compliance. Gassmann et al. (2011) link insufficient refuges to field-evolved Bt resistance in corn rootworm. Non-recessive inheritance reduces refuge efficacy, demanding adaptive policies.
