Re: [nafex] BT-kurstaki

The green ones may be the omniverous leaf tier.  They tie the edges of a leaf together with silk and hide in that.  It probably protected them from the Bt.  Sometimes they will "silk" a leaf to a green fruit and eat the surface of the fruit as well.  They feed on a lot of species.

Here, the BT was sprayed by helicopters two weeks ago. We received info by mail that this was going to take place.
I find the caterpillars on plants but nothing has been touched. Some are still alive but weak. Only the cherry trees carrying the original web are chewed. Some caterpillars are still in the web, but they are small and not very active.
Other little worms, like the green one with dark head that is found in a terminal leaves on apple trees does not seem to be affected.

Look for at least 24 hours before they begin to die - normally however they
cease eating almost immediately upon consumption.  We have very active BT
Kurstaki that was prepared in Feb 2000.
