Hi,
What is this fly on my tomato plants? How do I get rid of them?

Hi srikanth,
That is an infestation of aphids on your plant.
GG has suggested 1: 1 mix of spirit or rubbing alcohol to water spray.
Chemicals I would suggest is rogar or dimethoate if flower has not yet set.
Another simple method would be to mix a tsp of Vim drop or Pril liquid to a
big mug of water and spray the underside of leaves thoroughly early in the morning
before sunlight falls on the plant. Otherwise this spray can burn the plant leaves and you'll end up with splotchy leaves.
Hope this works

BRB,
Are you sure? I hope you are not looking at the spinach plants. The one I am referring to is a tomato plant. (I am not sure how picassa links work – does it open the picture directly or the folder).
Aren't aphids white in color? This one is black in color with transparent wings.

Srikanth,
BRB is right. It is an aphid.
In aphids, there are several forms. this one is a winged aphid. There are two ways aphids get onto a plant. One is through ants and other is by flight. (or flyt as you mentioned in the title :P..
The winged aphids are the first ones to visit a plant and then they start reproducing. Aphids can control the sex of the new born and the new born is born pregnant and anytime they can control if they will give birth to a winged version or a non winged version. When a plant is full of aphids and nothing more to eat, they make winged versions and move to another plants.
This is for sure aphid. Neem extract (azadiractin) was helpful in getting rid of it. But it requires more than one application.
Hope this helps.

Not just the children even adults are fascinated learning about the winged and non-winged aphids.
My setup is coming along OK. Nothing to rave about yet. I took a few pictures just this morning posteriety's sake. I have added a lure and bait for Spodoptera and captured about 10 moths overnight. I have also added Yellow sticky trap but that did not catch any winged aphids yet. May be the location was not right.
My beafsteak Marmande had suffered shock due to utter shortage of water. I did not realize how fast the plant grows and with it the nutritional requirement. I think it is now slowly coming out of shock. I have about 4 types of tomatoes now (Marmande, Cherry, one Hybrid and one local variety). I had cloned the local variety through stem and it has come up very good. I never really had a good Marmande yield so far. I would like to graft it with the local variety in a month or two.
What I thought was a Cherry is probably not one. The fruit are just about setting now. The fruits are elongated, eliptical instead of being round.
I mananged to get only one Capsicum seedling (the rest did not sprout properly). This one now has 5 capsicums on it. They look kind of cute.
I still have the problems with the leaking growbags. I need take time to plug them all. It now malkes me wonder if I should have gone with pots like UG but then that would pose a different set of problem like surface evaporation.
I will post some pictures and updates later.
