RE: HELP! Big green caterpillars are eating my tomato plants!

I see your new to the forum. Glad to have you. In the tomato forum ( not this one your in the tomato pest and disease forum) you can go to FAQ and gets lots of answers.You can also search by using key words in any forum. The info I'm posting came straight out of the FAQ'S.

In most cases you will only need to post your problem once give it a day or so for others to read.

Here goes

Tomato Hornworm - are 3-4" long green caterpillars with diagonal lines on sides, prominent horn on rear end. Eat foliage and may take bites out of green fruit. Tomato hornworms are the larvae of 2 large moths: the Hawkmoth and the Sphinx moth and overwinter in the soil in the pupal stage. Adult moths appear in late spring and lay single,
pearl colored eggs on the undersides of plant leaves that hatch in about a week. Larvae feed on foliage for about a month before they enter the soil and pupate. They can be difficult to spot as coloring matches plant. Look for them on the undersides of leaf-stripped branches. They can easily be hand-picked and destroyed or if infestation is severe, use Bt (Bacillius thuringiensis) dust. Braconid wasps will kill these caterpillars by implanting rice-like eggs on their backs and Trichogramma wasps parasitize the eggs.

The BT works best on the young ones. Pic what you see and squish.Available at Home Depot and Lowes.

Have fun.

RE: HELP! Big green caterpillars are eating my tomato plants!

Hello, I am trying to identify a 1/2 inch green worm with a very long red horn. Grandson brought it to me from the grape arbor. I took a really nice closeup picture but do not know how to link it to this site. I can email it in jig form if anyone would like to see it and maybe tell us if it's a good guy or a bad guy. Thank you.

I noticed a stripped stem just this afternoon, but it was the only one, and I had a hard time finding the culprit. After much searching, I just found one worm on my plant, but it had little white cocoons on it. I did some research, and the cocoons are from some wasp that will do the caterpillar in once they hatch. I posted a pic of it in the gallery. I love gardening, you learn something new every day!

I had the thrill today to watch some wasps emerging from their cocoons on the back of my Hornworms. Remember: never pick infested Hornworms. They will do no more damage and you want to encourage the local wasp population by allowing the babies to complete their cycle and hunt down more Hornworms. I posted four wasp pictures today to my existing Hornworm gallery:

Cool pics, dougs! I've just found infested hornworms in the last week, and my kids & I have watched them closely--the neighborhood boys are fascinated!

Well I'd like to know what you can do to save a plant that has been TOTALLY stripped by a family of these monsters? Is there any hope for my tomatoe? or my pepper plants after an attack?

Tomato horn worms or cutworms? Anywho I noticed some defoliation last week and grabbed one off of the vine. Good stuff here, Thank you!

RE: HELP! Big green caterpillars are eating my tomato plants!

I found some this afternoon. (09/17) Wonder if that is why my tomatoes are big but green! It has been horrible weather here. I did find the white larvae on them that will soon be wasps. Maybe I will save them for when the Grandkids come if Tomato_Worm doesn't want them. Very intesting!

RE: HELP! Big green caterpillars are eating my tomato plants!

My tomato plants are done in by these green caterpillars so I've decided to let them continue their cycle. I do see small wasps around them but so far no eggs. What I want to know is the caterpillars are prolific poopers (my plants are in tubs so the poop lands on my patio) and my cat walks in it. Is their poop dangerous to my cat?

RE: HELP! Big green caterpillars are eating my tomato plants!

The tomato eating caterpillars are actually called tomato hornworms. They are completely harmless, except for the fact that they can consume a whole tomato branch in one to two days. They will not turn into butterflies, but they will turn into big, beutiful moths. Their poop is harmless, because it is just ground up tomato leaves, acting as a fertilizer to your plant.

if you see stripped leaves but can't find any hornworks - or only 1 or 2 - they are their just hard to find so take a black light out at night - they light up like a carnival
