Bedbugs raise genetic defense against pesticides

Insects turn on several genes to stave off effects of insecticides

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.

TOUGH BUGS Bedbugs (adults, nymphs and eggs shown) have developed multiple layers of resistance to pesticides, making it hard to control their populations.
