42. Ebola is a virus, and as such hard to adapt to mutiple creatures, as needed with a vector.

Now Mosquito do spread some Viruses, such as yellow fever, dengue fever and chikungunya. but as a rule it is hard for a virus to shift between different types of animals.

Present theory is that inside the Mosquito, the Mosquito isolate the virus so it causes no harm to the Mosquito, but when a human is bitten it is transmitted to the Human..

Being a Virus that needs a dual host to spread, such viruses had to spread in an area with both creatures it needs exists. In the case of the above three viruses that does not only include Humans but other primates, thus a co-evolution over millions of years.

Ebola has NEVER been transmitted by Mosquito and thus not considered a canidate for such transmissions. To better understand this concept here is a paper on how AIDS can NOT be transmitted by Mosquitoes. The reason given would also apply to Ebola:
