To escape the sting of insecticides, bedbugs boost activity of certain genes in their shells, a new study shows. Bedbugs are notorious for escaping unharmed by pesticides; understanding how the insects escape death could lead to better ways to fight the pests.

Researchers led by Subba Palli of the University of Kentucky in Lexington collected 21 groups of common bedbugs, Cimex lectularius, from four Midwestern cities. The researchers examined the activity of genes that slough off the effect...
