Opps, should have included this: the eggs appear perfectly round. Thanks again!

Try looking very closely at the area where you think there are eggs laid in that split part of the stem. I am not convinced it is eggs. Tomato stalk borers (caterpillars) can bore into the stalks or stems of tomato plants, but their entry hole will be perfectly round---like a small nail hole---and the stalk borers hatch elsewhere and then bore into the stem. If you have stalk borers, they are easier to prevent than to kill after they appear. If you truly have something inside the stem, I don't know of any chemical treatment, either organic or synthetic in nature, that would kill them, that is available to the home gardener. It is hard to tell from looking at the photo, but I think it is most likely that what you are seeing are adventitious roots, often referred to by several different names including root initials or root primordials. They are fairly common and often develop during periods of high humidity or stress. They aren't harmful----they are the plant attempting to form more roots. They commonly develop on the stalk down near the ground, but can pop up in odd places sometimes, including at the site of a plant injury/wound. If you did have stalk borers, you would find them boring their way through the stalk of the plant similar to the way that squash vine borers work their way through stalk vines. If that were happening, your plant would be looking sad and wilty because the tunneling of a stalk borer would interfere in the way the plant's vascular system transports moisture and nutrients. I don't know of any insect that lays eggs inside a tomato stem. So, since I think it is likely you're seeing some adventitious roots, I've linked a photo that shows a split stem with adventitious roots forming in it. Does this look like the spot on your plant?

i would go buy the appropriate systemic product .. that is to be mixed into the media ... hoick that thing out into the yard.. apply to the soil as directed.. and leave it outdoors for a week or two in your zone .. IN FULL SHADE ... while it does it thing.. and off-gasses any stink ... and then drag it back in the house. .. actually.. what i would do.. is decide the plant isnt worth the cost of the product, nor the effort .. and chuck it in the garbage.. and go get another CLEAN plant to enjoy in the house ... this is where you now add that it is a treasured family heirloom.. and your life cant go on without it.. if so.. start reading at top again.. lol ... others have other ways to do it.. above is what i would do.. all the power to you and them otherwise ... scale is just a big PIA .... and i fight fire with fire.. not hopes and dreams.. lol ... ken

I have about 5 tomato plants in the garden. They have plenty of fruit on them. For the past 2-3 weeks the leaves have kind of folded in half. The wasps also have been going in and out of the folded leaves. Lots of wasps. I cut off a leaf just now and saw some pinhead size (some smaller), brown little larvae. I think it's larvae, but they are moving around. They are football shaped. So maybe not larvae just tiny insects. No wings. They are on the top side of the leaf. I think this is going to kill my plants. Does anyone know what this is? I am in Colorado, about 5,700 ft. z5
