A commercial airlines passenger on Aug. 9 carried the rice containing a dead adult, living larva and cast-off skins, said Lee Harty of U.S. Customs and Border Protection.

Another shipment of rice from Saudi Arabia that originated from India arrived at LAX in late December or early January with an adult Kharpa beetle and eight larvae in it.

The beetles, which originated in South Asia, are among the most destructive grain pests. They have been eradicated in the U.S. several times, then accidentally reintroduced.
