CDFA Pest Prevention Plant Regulation Practice Exam

The imported fire ant is native to which region?

1. Native insect

2. Introduced from South America

3. Introduced from Africa

4. Introduced from Asia

The correct answer is: Introduced from South America

The imported fire ant is indeed introduced from South America, particularly from regions such as Brazil and Argentina. This ant species was first identified in the United States in the early 20th century, likely through shipping containers and other means of transportation. Its introduction has led to significant ecological and economic impacts, as imported fire ants can outcompete native ant species and pose threats to agriculture, wildlife, and human health through aggressive behavior and painful stings. Understanding its origin is crucial for pest management and control strategies, as it informs researchers and regulators about the ant's behavior, habitat preferences, and potential for spread. The identification of its native region helps scientists develop better methods to manage and prevent the further spread of this invasive species, highlighting the importance of addressing biosecurity risks associated with shipping and international trade.
