Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.
A wide variety of insects (such as mosquitoes, shown here) are raised in the laboratory. A new review of research on lab-reared insects shows that they evolve rapidly as they progress through generations raised in artificial environments.
