Plant virus transmission strategies in insect vectors. Plant viruses need to be transmitted by a vector, most often insects such as leafhoppers. One class of viruses, the Rhabdoviridae, has been proposed to actually be insect viruses that have evolved to replicate in plants. The chosen insect vector of a plant virus will often be the ...
Since viruses are obligate intracellular parasites they must develop direct methods of transmission, between hosts, in order to survive. The mobility of animals increases the mechanisms of viral transmission that have evolved, whereas plants remain immobile, and thus plant viruses must rely on environmental factors to be transmitted between hosts.
Insects that act as vectors for plant diseases arising from bacteria, viruses, viroids and other pathogens. Pages in category "Insect vectors of plant pathogens" The following 74 pages are in this category, out of 74 total.
Plant viruses are generally transmitted by a vector, but mechanical and seed transmission also occur. Vectors are often insects such as aphids ; others are fungi , nematodes , and protozoa . In many cases, the insect and virus are specific for virus transmission such as the beet leafhopper that transmits the curly top virus causing disease in ...
Due to the large natural environment and hundreds of hosts Vector transmission allows the virus a range limited only by the reach of the insect. (3) [ 13 ] Greenhouses provide ideal environments for Western Flower Thrips and preventative measures must be taken in order to insure healthy plants.
This article contains a list of insect-borne diseases. They can take the form of parasitic worms , bacteria , protozoa , viruses , or the insects directly acting as a parasite. Insect-borne diseases
High-density planting can facilitate the spread of the virus when mealy bugs are able to go from plant to plant through the interlocked canopy. [11] [12] Aside from crawling from plant to plant, mealy bugs can be dispersed by wind as well. In controlled trials, 340 feet was the maximum distance a mealy bug could be spread from an infected plant ...
The interactions between aphids and CIRV-infected plants have been examined to determine factors influencing these vectors' virus transmission efficiency. Plant-Plant Transmission: Research has also explored non-vector-mediated transmission of CIRV, mainly through mechanical means. Understanding how the virus can be mechanically transmitted via ...
