Thrips tabaci is a species of very small insect in the genus Thrips in the order Thysanoptera. It is commonly known as the onion thrips, the potato thrips, the tobacco thrips or the cotton seedling thrips. [1] It is an agricultural pest that can damage crops of onions and other plants, and it can additionally act as a vector for plant viruses.
They have been used in companion planting as pest control in agricultural and garden situations, and in households. Certain plants have shown effectiveness as topical repellents for haematophagous insects, such as the use of lemon eucalyptus in PMD, but incomplete research and misunderstood applications can produce variable results.

They are polyphagous as they feed on a wide range of different fruits and ornamental plants. [6] [7] [10] Ornamental plants that they infest are the azaleas, calla lilies, chrysanthemums, fuchsia, roses [5] and orchids. [6] They also are considered pests to ferns, [8] palms and vines and vegetative plants as well. [15]
Selenothrips rubrocinctus, commonly known as the redbanded thrips, [2] is a species of thrips in the family Thripidae. It was first described from the West Indies but may have originated in northern South America. It has spread to other parts of the world and now has a near pan-tropical distribution, occurring in North, Central, and South ...
Scirtothrips dorsalis, the chilli thrips [derivation 1] or yellow tea thrips, is an extremely successful invasive species of pest-thrips [1] which has expanded rapidly from Asia over the last twenty years, and is gradually achieving a global distribution. It has most recently been reported in St. Vincent (2004) Florida (2005), Texas (2006), and ...
The western flower thrips [Frankliniella occidentalis (Pergande)] is an invasive pest insect in agriculture. This species of thrips is native to the Southwestern United States [1] but has spread to other continents, including Europe, Australia (where it was identified in May 1993 [1]), and South America via transport of infested plant material. [2]
Cannabaceae are often dioecious (distinct male and female plants). The flowers are actinomorphic (radially symmetrical) and not showy, as these plants are pollinated by the wind. As an adaptation to this kind of pollination, the calyx and corolla are radically reduced to only vestigial remnants found as an adherent perianth coating the seed. A ...
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]
