Because it would not be a fresh supply and the full mosquito has already begun digesting the blood drink in its system

Mosquitoes are not adapted to take up a blood meal from other mosquitos. The proboscis of a mosquito has not been adapted to efficiently penetrate the stomach of another mosquito. Plus, it's just much simpler to land on a large animal and pierce its skin to take up a blood meal.
Keep in mind that only female mosquitos take blood meals. The blood is used in reproduction. The typical mosquito diet does not contain the protein required for egg development, so female mosquitos need to take up blood when producing eggs.
Because blood is only needed for this very specific operation, there is no guarantee that any given mosquito will have blood within it, so that's another reason why it's inefficient to seek out full mosquitos.
And finally (and perhaps most importantly) if mosquitos dined on each other, those mosquitoes would be at a severe survival disadvantage compared to mosquitoes that did not. In other words, there would be fewer mosquitoes available to spread the "cannibal gene" because those mosquitoes with the gene would be preventing others with the gene from surviving to reproduce. There is already enough survival pressure due to scarcity of blood (remember that at some point a mosquito needs to take up a blood meal from an animal). It isn't going to help things if mosquitos need to also take time to defend themselves from other mosquitos.

first of all no human lets a mosquitoe suck blood from his or her body
it is because they are very small in size and are very carefull when sucking blood so we do not get to know but if a mosquitoe tries to suck blood from another mosquitoe what do you think that the other mosquitoe wouldn't get to know

Mosquitoes have evolved to drink blood from warm-blooded animals only, hence mammals and birds. As a way of distinction, they use the carbon dioxide emitted by those animals.
Other insects, including their own species, don't emit the amount of CO2 to trigger that signal.

They may be small, but they're not dumb. If one mosquito pierces anothers "blood sac" the one being pierced would die.
