CANBERRA, Australia (Reuters) — Australia has detected the larvae of khapra beetles in imported baby diapers sold in supermarkets nationwide, the agriculture ministry said, raising concerns the pest could infest grain storages and disrupt agricultural exports.
The ministry said in a statement late last month that it had been working with the importer and retailer to trace and treat diapers containing the insect since it was alerted to their detection in New South Wales earlier in the month.
Agriculture minister Julie Collins said the beetles, which feed on stored food, making it unusable, hitchhiked to Australia in a shipping container.

Fertilizer method’s link to emissions studied
A researcher says others studying greenhouse gas emissions aren’t considering how the loss of nitrogen into the atmosphere correlates with fertilizer application or if there is an impact to yield.
“We’ve managed to track down around 1,500 of the 2,000 cartons (of diapers) but there are still some in circulation,” she said in an Australian Broadcasting Corporation.
“We want to of course make sure that this doesn’t take hold anywhere and we’ve got them all,” Collins said.
Australia is currently free of the khapra beetle, a tiny brown insect up to three millimetres long. The maggot-like larvae are a little longer, up to 4.5 mm, golden-brown and hairy.
The agriculture ministry classifies khapra beetles as the biggest pest threat to Australia’s A$18 billion grains industry, saying their establishment in the country would cause trading partners to reject Australian goods, causing huge losses.
Australia is one of the world’s biggest exporters of wheat, barley and sorghum.
“This is a pest that would have the same impact as a foot-and-mouth animal disease outbreak in Australia,” said Xavier Martin, president of farm industry group NSW Farmers.
“Governments have to do everything in their power to contain and eradicate this pest, or the damage will be beyond our worst nightmare,” he said.
Woolworths, Australia’s largest supermarket chain, said the diapers were supplied by Belgian manufacturer Ontex.
Ontex said it did not know where the larvae had come from but there was no evidence they were introduced when the diapers were being produced.
“Operations at our Eastern Creek manufacturing and warehouse facility (in Sydney) have been suspended until comprehensive checks are completed and we receive confirmation that manufacturing and shipping can safely resume,” it added.
Khapra beetles are native to India but have spread through numerous countries in Asia, Africa and Europe, according to the ministry.
