Asian beetle threatens hardwood
Asian beetle threatens hardwood Scientists are searching Canada for a beetle which
could be a threat to Canada's hardwood tree populations. The Asian
longhorned beetle, which kills the trees it infests, has been found
in trees in Chicago. It is thought that the beetle arrived in North
America in the wood of packing crates from China. Although it has
not yet been found in the wild in Canada, the beetle has been found
on packing materials which have arrived in Canada. This has led to
fears that some may have escaped into the wild. Trees in areas
which receive goods from China in wooden containers are being
searched for signs of infestation. The only way to stop the beetle
is to cut down infested trees and burn them. The beetle is 2 to 3.5
cm long and is black with white spots. It has long antennae which
are banded with white and black and could feasibly threaten the
majority of Canada's broadleafed trees. 18 AUGUST 1999
