The ability of piercing-sucking insects to transmit plant disease is closely linked to feeding mode and target tissue the true bugs (heteroptera) are generally considered to be of minimal importance as vectors of plant pathogens, although they share similar feeding behaviors with homopterans modes.

In response to recommendations developed at the workshop, the two institutes established a human pathogens and disease vectors sequencing target selection working. Culicidae mosquitoes in the genus anopheles are the principle vectors of malaria, a disease caused by protozoa in the genus plasmodium aedes aegypti is the main vector of the viruses that cause yellow fever and dengue other viruses, the causal agents of various types of encephalitis, are also carried by aedes spp mosquitoes wuchereria. The transmission of insect-borne plant pathogens, including viruses, bacteria, phytoplasmas, and fungi depends upon the abundance and behavior of their vectors these pathogens should therefore be selected to influence their vectors to enhance their transmission, either indirectly, through the infected host plant, or directly, after.

Vector-borne diseases are illnesses that are transmitted by vectors, which include mosquitoes, ticks, and fleasthese vectors can carry infective pathogens such as viruses, bacteria, and protozoa, which can be transferred from one host (carrier) to anotherin the united states, there are currently 14 vector-borne diseases that are of. Evidence supporting the role of caenorhabditis elegans, a common laboratory model system, and other free-living helminths, as potential vectors of pathogens include a number of studies that have found bacteria to survive internally to the helminth and to have increased survival [3 – 7], figure 1)additionally, ingestion of c elegans has.

From the perspective of infectious diseases, vectors are the transmitters of disease-causing organisms that carry the pathogens from one host to another by common usage, vectors are considered to be invertebrate animals, usually arthropods technically, however, vertebrates can also act as vectors. Understanding how vectors transmit pathogens increases knowledge of their epidemiologies and needed for development of disease.
