Vector Competence

Reference work entry
DOI: https://doi.org/10.1007/978-1-4020-6359-6_3945

The ability of a potential vector to actually vector a disease. Many arthropods are capable of vectoring disease in an ideal (e.g., laboratory) environment, but fail to be effective vectors in the field. Some factors influencing vector competence include age of the vector and host, synchrony of vector and host, availability of alternate hosts, behavior/host preference of the vector, ability of the disease organism to maintain or increase titer in the vector, environmental conditions, prior exposure and host resistance.
