The same reason you don't get colds from your dog.
Infectious diseases are usually specific to the physical traits of certain species. Sometimes, if there are similar organisms living close together, the germ/parasite can make the leap but this is more rare (like bird flu).
The parasites that cause malaria don't bother the mosquito they just use the mosquito to jump to a new host (one that has the type of blood they like to munch).

Because the parasite (not germ) that causes malaria requires red blood cells and mosquitos don't have red blood cells.

In epidemiology, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another.
A classic example is the anopheles mosquito which acts as a vector for the disease malaria by transmitting the malarial parasite plasmodium to humans. In this case plasmodium is harmless to the mosquito (its intermediate host) but causes the disease malaria in humans (its definitive host).

Because mosquitos are cold blooded, they dont have haemoglobin , so the virus wont spread or infect mosquitos due to lack of sufficent temperature, they'll simply carry the virus and spread it to hot bloods.

because malaria isnt a germ, its a parasite that has to live in red blood cells
