Green tiny bug, not an aphid

[Ms. Jitomate]

What is this? They are hard to find but I see their damage in my tomato plants. They don't move and they are soft. I always find them in the underside of the tomato leaves. Looks like they chew small holes in the tomato leaf.

That is a whitefly larva I think. Translucent body, leg less with those striations.
Neem works well.

Maybe it's a scale insect. At first you might notice only one or two and suddenly the plant can be covered. There's all different types depending on your area.

[Ms. Jitomate]

I haven't seen any whiteflies, yet. I usually don't get any on my tomatoes, but this is the first time I'm having some success with heirloom tomatoes.

What I have been seeing is gnat-like flies, some aphids, and an occasional green caterpillar. I have been blasting with the water hose to control the aphids. I don't think the water blasting is strong enough to knock out the little green bugs. I pick out the caterpillars if I find them. Usually I look above their poops. I also found some little white crystals, smaller than salt crystals, on a leaf which I thought was strange. I ordered a sticky glue from Tanglefoot to try to trap the gnat-like flies to identify them.

Are the gnat-like flies a problem on tomatoes? They are very fast so I can't take a picture of them.

It kind of looks like a psyllid to me. I've had these buggers the last couple of years, along with russet mites. Terrible things!

Psyllids leave that crystally, sugary substance behind. They have a toxic saliva that really does a number on tomatoes. I've used Take Down with pretty good results.

I don't know what they are but I get them in small numbers up here in the Bay Area too. Never caused me much trouble so I never tried to find out what they are. I assumed they were some kind of scale insect.

[Ms. Jitomate]

Sprout, I think you are right. It looks like a tomato psyllid. Using your information I found this UC Management link, http://www.ipm.ucdavis.edu/PMG/r783303011.html and I went to their nymph link and that's how they look. They suggest a spraying of "Entrust formulation of spinosad" and "it is very important not to use carbamates (Sevin-foliar applications, Lannate, Vydate) for the control of other pests as these materials actually promote the development of psyllid populations."

I have no idea what these products are so I'll visit my nursery to inquire about "spinosad," but so far it doesn't look like an infestation and I don't have any yellowing. I do have some curling in a couple plants (Red Boar and Pink Boar) but I thought that was natural. Today after some rain I went out and noticed leaves with discoloration, uneven green (also on the Red and Pink Boar and Sweet Carneros Pink). The psyllids were on my Russian Queen. I'm still waiting for my sticky trap glue to identify the adults.

Good catch Ms J !,

Entrust- phew 600-$700 for 4.4oz? No thank you DOW company. Its said to be a alternative to BT so it does not create resistant insects???? What is that implying? Insects can become resistant to BT?

"It is a new class of pesticide which can be used alternately with Bt to reduce the chances of creating resistant insect strains"

Found this bug, but it doesn't look like the picture of the adult tomato psyllid in the UC Management link. Is it a good bug or bad bug?
