Where is the Colorado potato beetle originally from?

  1. France

  2. Germany

  3. United States

  4. South America

The correct answer is: South America

The Colorado potato beetle is originally from South America. It specifically hails from the Andean region where it historically developed on wild nightshade species. This background is significant as it shapes the beetle's adaptations and behaviors in different environments, particularly those related to the consumption of potato plants, which are not native to South America, but were introduced later. Understanding the native habitat of the Colorado potato beetle helps researchers and agricultural specialists develop better management practices for controlling its population and mitigating the damage it can cause to potato crops.
