NOGALES, Ariz. (AP) -- Border agents in Nogales say they've recently stopped three harmful foreign insects from entering the United States from Mexico, and that two of them have never before been found in the U.S.
Agents said Monday that on Aug. 11, agricultural specialists found an adult weevil, also known as a snout beetle, among pineapples and Persian limes.
On Sept. 6, specialists found an adult Hemipteran insect among tomatoes. The insects can damage crops by piercing plant tissues and feeding on the juices.
Within minutes of finding that pest, inspectors found two adult shield bugs among corn; they have piercing mouth parts that can suck sap from plants.
Agents say the weevil and the shield bugs have never been found at a port of entry.
