Researchers at the American Museum of Natural History and Weill Cornell Medicine took DNA and RNA from both living and preserved bedbugs. They retrieved samples from a bedbug population first collected in 1973 (and since maintained by the museum), as well as from more than 1,400 locations in New York City, including every subway station.
What they found was that gene expression changes after a bedbug has its first blood meal. Some of the genetic mutations the bedbugs undergo allows them to develop resistance to insecticides by creating a better internal detoxification system or by forming a thicker skin.
Knowing this, attacking the bugs during their nymph stage, before they first drink blood, could be smart strategy for stopping them in their bloody little tracks.
