According to the university of Fla, bt does work for worms that you can see but they burrow after hatching and then it's no longer effective...and can be difficult to control if their numbers are allowed to multiply. I'll find the link.

From the article that claude attached, it looks like you need to apply the bt when they are out in the open and eating the leaves. After they make a web and roll the leaf over themselves, they will be harder to treat.
I use Thuricide bt on bagworms that I get in my evergreens. The solution won't penetrate the protective bags that the worms live in but when they come out to eat leaves, they ingest the bt and die in a period of about 3-4 days.
According to the original article that I attached, Spinosad can also be effective. It doesn't say anything about Neem.
Spinosad is a stomach poison and is effective against caterpillars but it can also be toxic to bees so apply it at night.
Good luck with your tomatoes. That looks like a bad pest to have. It's another good reason for us northerners to grow our own tomato plants and not buy transplants which can carry the eggs. Scary.

Thanks for all the help on my worm problem. I've joined Photobucket as recommended by Steve but can't transfer my pics to it from my phone. I'm challenged in that department but will get my hubby to help tonight.
We had to postpone our vacation (yay) for 2 weeks so maybe I can get a handle on this before leaving. Those worms have good taste because they are going after the Brandywines and leaving the others alone.

I am not a Photobucket expert but there is a mobile app for smartphones. Probably you want to get that.

Hoping this is a picture of the worms on my tomato plants. My first time to try posting a pic. I appreciate any comments because I've seen two pictures of worms labeled as pin worms and they don't look the same.

I thought I did it correctly but this picture is huge. I must have missed a step.

I read the directions again and am completely befuddled because I can't figure out where I went wrong with my giant picture.

naturegal- Great job. You did it! And that is a pretty typical picture size from PB. There are those words "this image has been reduced" in tiny blue print above your pic, so it was reduced and you are OK.
Sorry, no input on the worm. I haven't gotten them. I think my arid conditions and 7000' elevation might have something to do with it.

It seems similar but before applying insecticide, can you bring one of those worms up to your extension service in a plastic bag for identification? The thing is with some pests they change colors during different stages of development. Whenever you bring a pest for ID, always enclose in so that they can see it but it can't escape and infect there at the extension service. They may even be able to ID w a photo if you can also photograph something for size..like a ruler or dollar bill.

That doesn't look like the caterpillars I had. I believe what I had were what claude said...leaf rollers. Thank you...by the way, claude...I had no idea what I had... Your picture looks more like a cutworm type...???...would have to do more picture research on that... I'm no scientist when it comes to these things, but I personally would try bt for caterpillars of most types. That said...that doesn't mean I want to go out and kill every caterpillar I see!!! Just destructive ones! Lucky for you to have a couple extra weeks to hopefully get the upper hand on them!

Ahnjudy..that's why I love these forums..we learn so much from others..gardeners like Brownrex, DW, lat, James, gaK, BG (and I include everyone)bring a wealth of information. And share it so willingly..it gives me faith in others and myself as well.

I can't figure out where I went wrong with my giant picture. Go to Photobucket and click on the head avatar at the top right hand side of the page, next to the cart. Click that and choose Settings then Albums and then scroll down to Upload options and click on Customize Upload Options. You posted at 600 x 800 but you can choose a smaller size to automatically upload in the future. I use 640 x 480 for mine and it seems like a good size and I don't need to worry about re-sizing anything.

BR- do you have to do that each time you post a pic or is it that once you customize, they will always post at that size?
