(a) A mechanical vector carries a pathogen on its body from one host to another, not as an infection. Biological insect vectors include mosquitoes, which transmit malaria and other diseases, and lice, which transmit typhus.Click to see full answer. Also, what is a biological vector?Vector (biology) Traditionally in medicine, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. Species of mosquito, for example, serve as vectors for the deadly disease Malaria.Secondly, what is mechanical transmission? Mechanical transmission means the transfer of pathogens from an infected host or a contaminated substrate to a susceptible host, where a biological association between the pathogen and the vector is not necessary. Similarly one may ask, what is the difference between mechanical and biological transmission? The basic difference between biological transmission and mechanical transmission is that in biological transmission, the agent develops and/or propagates within the vector, while in mechanical transmission, the simple transfer of agents from one infected host or a contaminated substrate to a susceptible host occurs.What is the difference between pest and vector?The term “pest” is a very broad term that basically defines organisms that are an annoyance to humans because they are in places we don’t want them to be, like our homes. Examples of pests include: ants, bed bugs, lice, mosquitoes, and wasps. Vectors are organisms that transmit disease to humans.
