What is the connection between DDT and pyrethroids? They are both pesticides, but different ones. However, many mutations that protect the bugs from one of them also work on the other.

So, if they had been exposed, they'd be selected for resistence to these pesticides. But if they have not been exposed; they would be dying more often during the last decade.
