A new study traces the German cockroach’s evolution throughout human history.
About the German cockroach(Blattella germanica)
It is one most widely found around the world.
It seeks warm moist conditions with access to food and water. • It is common in domestic kitchens and commercial food-handling areas and is active at night, hiding during the day in dark, secure places.
The recent analysis revealed that the German cockroach evolved from the Asian cockroach (Blattella asahinai) about 2,100 years ago.
The two species are still very similar today.
According to the researchers, the insects originally adapted to human settlements in India and Myanmar.
Issues and Concerns: Cockroaches act as vectors for a great many bacteria, viruses, and fungi.
They can trigger allergies and cause diarrhea, colitis, hepatitis A, anthrax, salmonella, and tuberculosis. Cockroaches can also spread foot-and-mouth disease.
