Release Date: 
March 14, 2013

BALTIMORE—A U.S. Department of Agriculture (USDA) entomologist confirmed Wednesday that U. S. Customs and Border Protection (CBP) Office of Field Operations (OFO) agriculture specialists at Baltimore Washington Thurgood Marshall International Airport discovered a new pest in the Baltimore area when they intercepted, Paraselenaspidus madagascariensis, a type of scale insect, while inspecting banana leaves found inside of a traveler's luggage on November 30, 2012.

Scale insects can pose a significant agriculture threat because they draw sap directly from a host plant's vascular system weakening it. Infestation can lead to a decrease in productivity and quality of crops, which can result in significant economic loss. Scale insects are known to have a waxy covering which makes them quite resistant to pesticides.

"CBP agriculture specialists are very good at detecting foreign invasive plants and plant pests," said Ricardo Scheller Port Director for the Port of Baltimore. "This discovery highlights the importance of the work they do, part of which is protecting the U.S. agriculture industry."

The insects were discovered on banana leaves being carried by a passenger originating from Nigeria and arriving from the United Kingdom. CBP seized the infested banana leaves and forwarded a specimen to a USDA- Animal and Plant Health Inspection Service (APHIS) - Plant Protection and Quarantine (PPQ) entomologist for identification. The remaining leaves were then destroyed by incineration.

CBP agriculture specialists work closely with USDA's, APHIS, PPQ to protect our nation's agriculture resources against the introduction of foreign plant pests and animal diseases.

CBP agriculture specialists have extensive training and experience in the biological sciences and agricultural inspection. On a typical day, they inspect tens of thousands of international air passengers, and air and sea cargoes nationally being imported to the United States and seize 4,919 prohibited meat, plant materials or animal products, including 476 insect pests.
