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.
It is largely spread by the insect vector of the western flower thrips. The virus infects more than 648 species of plants including important horticultural and agricultural species such as fuchsia, tomato, orchids, [2] and lettuce (especially romaine). As the name implies, the main symptom on plants is necrotic spots that appear
Transmission electron micrograph of tomato spotted wilt virus. The circulative propagative transmission of TSWV is carried out by at least ten different species of thrips. [2] The most common species is Frankliniella occidentalis (western flower thrips) as it is the vector that predominantly transmits TSWV globally and in greenhouses.
The electrical penetration graph or EPG is a system used by biologists to study the interaction of insects such as aphids, thrips, and leafhoppers with plants. Therefore, it can also be used to study the basis of plant virus transmission, host plant selection by insects and the way in which insects can find and feed from the phloem of the plant.
A large number of plant families are known to be affected by viruses of the Tospovirus genus. These include both food crops (such as peanuts , watermelons , capsicums , tomatoes , zucchinis , et al. ) as well as ornamental species which are important to flower farms ( calla lily , impatiens , chrysanthemums , iris , et al. ).
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.
When it sucks the sap of an infected plant it receives groundnut rosette virus and satellite RNA, packaged together within a coating of groundnut rosette assistor virus. The disease is epidemic in nature and there is a seasonal cycle of infection, but the origins of this virus are unknown. In Africa, the groundnut aphid feeds on as many as 142 ...
