International Team Sheds Light on 250-Year-Old Mystery of the German Cockroach

A team of international scientists, including Virginia Tech entomologist Warren Booth, PhD, has solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and 6 continents, show that this species evolved some 2,100 years ago from an outside species in Asia. The results were published May 20, 2024 in PNAS. The open-access article is titled “Solving the 250-Year-Old Mystery of the Origin and Global Spread of the German Cockroach, Blattella germanica.”
