Summary
The evolution of pesticide and drug resistance plagues agriculture and medicine
worldwide. Resistance may stem from a single major gene or from quantitative sources, and
both have been observed in the same species. The genetic basis of resistance plays a key
role in treatment, as low doses facilitate the evolution of quantitative resistance, while high
doses select for rapid appearance of major gene resistance. When crop rotation or
pesticide rotation is unfeasible (e.g. orchard crops or pest cross-resistance to multiple
