SPECIAL CORRESPONDENT WASHINGTON A 20-foot shipping container of rice has been returned to India after US customs authorities in Los Angeles found evidence of a destructive beetle in the shipment, according to media reports. Customs officials said that dead larvae were found on the outer seam of a bag of rice in an inspection earlier this month. Testing came back from the federal laboratories on September 7 that confirmed the dead larvae were Kharpa beetles. The Kharpa beetle is a very destructive pest that eats stored grain, dried plants and dog food, according to the reports. Kharpa beetles are resistant to fumigation, can survive without food or water for long periods and can hide in tiny cracks. As of September 9, customs officials said they have intercepted 145 containers with Kharpa beetles at U.S. ports of entry this year.
