Don't kill them! They sound like tomato hornworms that have been parasitized. The white sacks are eggs from a small parasitic wasp. The caterpillars are doomed (they feast on tomato leaves) and if you don't kill them, a new flock of small wasps will emerge to protect your garden. Just remove them from the tomatoes and let them live. -Kristina -----Original Message----- From: owner-tomato@GlobalGarden.com [mailto:owner-tomato@GlobalGarden.com]On Behalf Of tfarmer@att.net Sent: Monday, September 11, 2000 1:59 PM To: tomato@GlobalGarden.com Subject: I have some tomato plants in a planter on the deck. I noticed 2 caterpillars on them. They are large (about 2 inches long) green with white sacks attached all over their bodies. I noticed black droppings on the deck under these bugs. The plant is producing plenty of fruit but seem a little wilted but I think that is more a factor of water (they dry out quickly in the planters) I have one plant out in the yard that apparently does not have any of these pests on there yet and it is doing fine. Anyone know what these are? Can I just kill them and be done with it or are more steps needed? Tom St. Louis, MO __________________________________________________ Do You Yahoo!?
