A biological vector is an organism, typically an arthropod or other animal, that transmits pathogens from one host to another. For example, mosquitoes can act as biological vectors for diseases like malaria and dengue fever by transmitting the pathogens that cause these illnesses when they bite humans.

In relation to malaria, the word 'vector' refers to the means by which a disease is transmitted, specifically an organic host. So bats, rats, ticks, fleas and Outbreak monkeys can all be vectors. In malaria's case, the vector is the mosquito. So you don't really use vectors to control malaria, but rather try to control malaria by stopping on the vector, i.e. get yourself a mosquito net or don't trek through the jungle.
No, DDT does not cause malaria. DDT is actually used to control the mosquito populations that spread malaria by killing the mosquitoes that carry the disease. Using DDT in a controlled and targeted manner can help reduce the incidence of malaria.

In terms of Epidemiology a vector is an organism which transmits diseases to healthy organisms. A biological vector develops an infected organism in its body and passes it along to its host. e.g mosquito while a mechanical vector carry an infected organism to its host through its legs and other body parts. e.g flies.
Vectors play very important role in spread of many diseases. The microorganism spends dominant or recessive stage of it's life cycle. Without the vector the disease can not spread in most of the cases. Malaria and plague are two important vector born diseases.
Viruses have proven to be highly effective as vectors since these are biological entities with a natural function of infecting host cells.
