  insect problem
From: David Thornton <dave at dave-aroid.demon.co.uk> on 1999.02.06 at 16:08:46(3006)
Dear all,

I wonder if anyone can identify an insect problem that has wiped out my
Colcasia esculenta and is now spreading over Xanthosoma.

It appears on the leaf surface and underside as small black
flecks,rounded bodies, on closer look they appear as small grains of
sand, some sand colour others black. I can see the odd one physically
moving about. Eventually more and more of these flecks appear and
strands of web like thread stretch between them.

The bodies are soft and easily crushed.

So far they have proved quite resistant to insecticide

Advice Please !
