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
Tomato spotted wilt orthotospovirus (TSWV) is a spherical negative-sense RNA virus. Transmitted by thrips , it causes serious losses in economically important crops and it is one of the most economically devastating plant viruses in the world.
Dicyphus hesperus has also been tested as a biological control for the western flower thrips (Frankliniella occidentalis) on tomatoes. It was effective at reducing the number of thrips but when the ratio of predator to prey was too high (>1:10), some damage was caused to the tomato fruits by D. hesperus. [7]
These pests commonly affect food crops like asparagus, tomatoes, and beans, but they also plague most houseplants and ornamentals, such as carnations, chrysanthemums, gladiolus, and pansies. Tips
The generic and English name thrips is a direct transliteration of the Ancient Greek word θρίψ, thrips, meaning "woodworm". [4] Like some other animal-names (such as sheep, deer, and moose) in English the word "thrips" expresses both the singular and plural, so there may be many thrips or a single thrips. Other common names for thrips ...
Thrips palmi is an insect from the genus Thrips in the order Thysanoptera. [1] It is known commonly as the melon thrips.. It is a primary vector of plant viruses.The melon thrips can cause damage to a wide range of glasshouse ornamental and vegetable crops, particularly plants in the families Cucurbitaceae and Solanaceae, such as cucumber, aubergine, tomato and sweet pepper.
As opposed to other species of thrips like the western flower thrip (Frankliniella occidentalis) or tobacco thrips (Thrips tabaci) that pupate in the soil, E. americanus pupates on the aboveground parts of plants. [8] Using their mouthparts to puncture the leaf surface, E. americanus will leave plants with a chlorotic and shrunken appearance. [11]
The cultured mites can be mixed with bran and sprinkled on the crop or spread by air blast. When multiple species of pest are present, it may effectively control one but not another; for example, in field grown cucumbers, it was found to control melon thrips on leaves, but failed to control common blossom thrips on flowers.
