The bedbug actually could be the bogeyman: it’s scary, it comes out at night, and like a horror movie, it’s now becoming resistant to our tools for wiping them off the face of the earth.
Ohio State University researchers mapped out the genome of laboratory-reared bedbugs and compared them to those that repeatedly survived pesticide treatment. They found that the latter expressed differences in a specific gene, suggesting that a good ol’ dose of chemical spray won’t help much in getting a good night’s sleep.
Bedbugs have proved to be a nuisance in the past, until the 1940s with the introduction of DDT. In the past few years, the problem has resurfaced with a vengeance. It’s not clear why the problem has taken hold again; but, the fact that they are becoming resistant could be a factor.
Brings new light to “Good night, sleep tight, and don’t let the bedbugs bite,” doesn’t it? (via New Scientist)
