I am not an expert on leaf miners but I think that you will have a difficult time with any insecticide killing the larvae which are already inside of the leaves. You may have success with killing the adult flies as they land on the leaves before they are able to lay new eggs but I don't really know.
However, as I read this I am thinking isn't it really really HOT in Saudi Arabia? I would use caution with spraying anything on your tomato leaves for fear of causing them to burn up in the heat. You would know better what you can do of course but I would recommend testing a small area first and see how the plants react before you risk spraying all of your plants.
