Dichromothrips corbetti<\/em> originates from Southeast Asia, but has been introduced into many other regions by plant trade, particularly with orchids. Within Europe, this thrips has not established outdoor populations; however, it has been recorded repeatedly in greenhouse environments in Belgium, Germany, Great Britain, the Netherlands, Slovakia, and Hungary. Dichromothrips corbetti<\/em> feeds and breeds on leaves and flowers of orchids (e.g. Vanda<\/em>, Phalaenopsis<\/em>, Cattleya<\/em>, etc.). Owing to its ability to build up populations rapidly under protected cultivation, Dichromothrips corbetti<\/em> is regarded as a noteworthy pest in orchid production.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” initial_loading_animation=”bounceIn” grid_id=”vc_gid:1763973873934-56afe9edfff17b7566d8d9485820a8d9-7″ include=”6554,6314,6317,6316,6315,7136,7135,6558,7134,6556,6557,4377,4344,4353,4343,4369″][vc_separator][vc_column_text css=””]<\/a>Drepanothrips reuteri<\/a> – <\/em>Vine Thrips<\/strong><\/p>\n

Drepanothrips reuteri<\/em> is widespread throughout Europe and has been introduced into other regions of the world, including the United States (Illinois, California) and Chile. The thrips feeds and reproduces on the foliage of deciduous trees, occurring particularly on Betula<\/em>, Corylus<\/em>, and Quercus<\/em>. In wine-growing areas, Dendrothrips reuteri<\/em> also inhabits the leaves and young shoots of grapevine (Vitis vinifera<\/em>), where it is regarded as a pest in viticulture and is commonly referred to as \u201cvine thrips\u201d or \u201cgrape thrips.\u201d Feeding activity causes necrotic tissue on leaves, resulting from the puncturing and sucking of plant cells.[\/vc_column_text][vc_media_grid element_width=”3″ item=”mediaGrid_SlideInTitle” initial_loading_animation=”bounceIn” grid_id=”vc_gid:1763973873957-f9ada658c7c38a844eddeb20ba867b7f-10″ include=”6319,6320,3734,3731″][vc_separator][vc_column_text css=””]<\/a>Echinothrips americanus<\/a> – <\/em>Poinsettia Thrips<\/strong><\/p>\n

Echinothrips americanus<\/em> has been introduced from the USA into Europe and was first recorded in the Netherlands in 1993. In Europe, this species is found exclusively in greenhouses or on indoor plants, showing a particular preference for Dieffenbachia<\/em>, Homalonema<\/em>, Philodendron<\/em>, Schefflera<\/em> and Syngonium<\/em>. E. americanus<\/em>, however, is highly polyphagous and has also been recorded on other plant species, including Asparagus<\/em>, bamboo, Impatiens<\/em> and poinsettia. Feeding damage typically appears as widely spaced marks, resembling injury caused by spider mites or excessive sunlight. In some cases, damage to flowers has also been observed.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” initial_loading_animation=”bounceIn” grid_id=”vc_gid:1763973873982-28186f0235ddcb341d207c979927c150-8″ include=”6327,6330,6326,6331,6329,6328,6325,6324,6323,6043,3735,3736″][vc_row_inner][vc_column_inner][vc_separator][vc_column_text css=””]<\/a>Frankliniella intonsa <\/em><\/strong><\/a>– European Flower Thrips<\/strong><\/p>\n

Frankliniella intonsa<\/em> is one of the most common flower thrips. It is widespread across Europe and the Palaearctic part of Asia, extending to Taiwan, northern Thailand, Bangladesh, northern India, and Pakistan. Frankliniella intonsa<\/em> has also been introduced to Canada and is now found in the northern USA. This thrips is highly polyphagous, feeding on a wide range of plant species. At high population densities, it is recognized as a pest, particularly on fruit trees, strawberries, and vegetables. In addition, F. intonsa<\/em> is known to transmit plant viruses, including tospoviruses such as TSWV, TCSV, and GRSV.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” initial_loading_animation=”bounceIn” grid_id=”vc_gid:1763973874017-78f9cf7e7fe35e8bace79e74644c25dd-4″ include=”6335,6334,6338,6333,6336,6337,5837,5841″][vc_separator][\/vc_column_inner][\/vc_row_inner][vc_column_text css=””]<\/a>Frankliniella occidentalis<\/em><\/strong><\/a> – Western Flower Thrips<\/strong><\/p>\n

Frankliniella occidentalis<\/em> is originally native to the southwestern United States. Through the international trade of plants, it has been introduced to many countries and is now widespread worldwide. In Europe, it is primarily found in the Mediterranean region, but also occurs in warmer areas of Central Europe, such as the Rhine Valley in Germany. In colder regions, it is mostly restricted to greenhouses. Frankliniella<\/em> occidentalis<\/em> infests a wide variety of plant species, feeding on both flowers and leaves. At high population densities, it can cause significant damage. In addition, Frankliniella<\/em> occidentalis<\/em> is a vector of plant viruses.<\/p>\n

Frankliniella schultzei<\/em> is widespread in tropical and subtropical regions and has been introduced to many parts of the world. In temperate zones, it occurs mainly in greenhouses. This thrips is highly polyphagous, feeding and breeding on both flowers and leaves. Interestingly, it also preys on leaf mites, which can make it a useful biocontrol agent. Frankliniella schultzei <\/em>is an important vector of tospoviruses on numerous crops, with the dark form typically serving as the primary vector. In Europe, the dark form is rarely reported, but occurrences have been documented in the Netherlands and Germany (Ulitzka, unpublished).[\/vc_column_text][vc_media_grid element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” initial_loading_animation=”bounceIn” grid_id=”vc_gid:1763973874081-ab992739b5e35763286f8779b05459f2-2″ include=”7125,7126,7127,7128″][vc_separator][vc_column_text css=””]<\/a>Gynaikothrips uzeli <\/i><\/a>– Weeping Fig Thrips<\/strong><\/p>\n

Gynaikothrips uzeli<\/em> originates from Southeast Asia but has been introduced to many other regions through trade in its host plant. It has been recorded from northern Australia and New Caledonia, as well as from numerous areas of the Americas. In Europe, it occurs only in greenhouses or on indoor plantings. Gynaikothrips uzeli<\/em> is monophagous and develops in rolled leaf galls on Ficus benjamina<\/em> (Moraceae). Adults feed on the central vein of young leaves, inducing an upward folding that eventually results in a closed leaf gall in which eggs are deposited. Gynaikothrips uzeli<\/em> is a subsocial thrips species that protects and tends its larvae.<\/p>\n

Originally from South America, probably Peru, Heliothrips haemorrhoidalis<\/em> is now widespread throughout tropical and subtropical regions worldwide and is also known in temperate areas as a minor pest, particularly on ornamental shrubs grown under glass. Larvae, adults, and pupae inhabit the undersides of the leaves of a wide range of trees and shrubs, including tea, Pinus<\/em>, and various ferns. This thrips is rarely found on herbaceous plants or on plants with soft foliage. Large populations are especially common on water-stressed hosts.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” initial_loading_animation=”bounceIn” grid_id=”vc_gid:1763973874181-627b1daf546cd4e8c0b86a7e23120ec8-1″ include=”6251,6250,6249,6245,4457,4452,6246,6384,6248,4450,6247,4448″][\/vc_column_inner][\/vc_row_inner][vc_row][vc_column][vc_separator][vc_column_text css=””]<\/a>Hercinothrips aethiopiae<\/em><\/strong><\/a><\/p>\n

Hercinothrips aethiopiae<\/em> originates from Africa but has been repeatedly introduced into Europe through plant trade.

Hercinothrips dimidiatus<\/em> was originally described from South Africa and is also known from Nigeria. It was most likely introduced to Europe through the trade in succulents. In 2015, Hercinothrips dimidiatus<\/em> was reported from Portugal, and it was later detected in the Gibraltar region and on Mallorca. Significant damage has been observed particularly on Aloe arborescens<\/em>, in some cases leading to the complete loss of affected plants.<\/p>\n

Hercinothrips femoralis<\/em> breeds and feeds on the leaves of numerous plant species, with a marked preference for Amaryllidaceae. Originally native to Africa, it has been introduced to many other regions through the plant trade and is now widespread across subtropical and tropical areas. In temperate regions, it is typically encountered only in greenhouses.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” grid_id=”vc_gid:1763973874349-71919178a0504012faf48ffcc6a1f50f-8″ include=”6395,6394,6280,6281,6617,6620,6619,6618,6287,6392,3740,6622″][vc_separator][vc_column_text css=””]<\/a>Limothrips cerealium<\/a> & L. denticornis<\/a> – <\/em>Corn Thrips, Grain Thrips, Barley Thrips or Thunderflies<\/a><\/strong><\/p>\n

Limothrips cerealium <\/em>has been introduced into many countries with cereals and is now regarded as semi-cosmopolitan. Limothrips denticornis<\/em>, in contrast, is native to Europe and Siberia but has also been introduced to North America and Australia. Both species develop on the flowering heads of grasses, including cultivated cereals, where they may reduce grain quality and yield by feeding on the developing tissues. Under favourable conditions, populations of Limothrips cerealium<\/em> may become extremely abundant, with reported densities of up to 10,000,000 individuals per hectare.<\/p>\n

In summer, both species are known for their mass flights (\u201cthunderflies<\/a>\u201d), although only females participate because males are wingless. In landscapes dominated by cereal crops, wind currents may transport large numbers of dispersing females toward buildings, which they readily enter. Owing to their pronounced thigmotactic behaviour\u2014seeking tight spaces\u2014they often accumulate and die inside narrow gaps of household items such as picture frames, photographic slides, clocks, or other enclosed objects, where they can cause aesthetic or mechanical problems.<\/p>\n

Large numbers may also crawl beneath beverage caps, creating hygiene concerns, particularly when crates are stored outdoors. Technical devices are another frequent target: thrips can enter smoke detectors and cause false alarms, and in computer monitors they may penetrate between the display layers. Once trapped and deceased inside, they appear as persistent, comma-shaped artefacts that cannot be removed without dismantling the device.<\/p>\n

On human skin, swarming Limothrips<\/em> may cause temporary irritation in sensitive individuals. However, these species do not feed on blood. They are primarily attracted to sweat and moisture and may occasionally prick the skin superficially with their stylets during exploratory behaviour, not as an intentional feeding action.<\/p>\n

Liothrips mirabilis<\/em>, known as the ‘Black Pepper Thrips’ originates from Sri Lanka, where it primarily occurs on black pepper leafs (Piper nigrum<\/em>). It has been introduced into the tropical regions of India, particularly in areas where pepper is cultivated. Further spread throughout tropical Southeast Asia is to be expected. Liothrips mirabilis<\/em> mainly infests young leaves, where its sucking activity causes characteristic damage. Typical symptoms include galls in the form of rolled or deformed leaf margins.

Sciothrips cardamomi<\/em> originates from tropical Asia and is a destructive pest there. In Europe it is not found outdoors and is not to be expected there. In protected cultivation (under glass) its establishment may be possible if suitable host plants (cardamom, ginger) are available. However, damage is expected to be rather low. S. cardamomi<\/em> reproduces on young flowers and leaves of cardamom plants. It feeds on seed capsules, flower buds and panicles. The injured tissues form a corky layer on the capsule surface which appear as scales. Such capsules appear stunted, malformed and shrivelled with gaping slits on the skin. The condition is popularly known as \u201ccardamom itch\u201d. Seeds from infected capsules give poor germination. At panicle formation stage, infestation causes stunting of panicles and shedding of flowers.[\/vc_column_text][vc_media_grid element_width=”3″ item=”mediaGrid_SlideInTitle” grid_id=”vc_gid:1763973874521-8eeafe868be6b626bc6cb8009139140e-3″ include=”6415,6412,6413,6414″][vc_separator][vc_column_text]<\/a>Scirtothrips aurantii<\/a> – <\/em>South African Citrus Thrips<\/strong><\/p>\n

Scirtothrips aurantii <\/em>is widespread across Africa, but has recently been introduced to Portugal and Spain; furthermore, it has been reported from Queensland, Australia. Although it is common on oranges and other citrus fruits, where it probably causes the most damage, S. aurantii<\/em> is highly polyphagous and can be found on a wide range of other plants. There are reports from over 70 plant species, including crops such as amaranth, asparagus, banana, cashew, castor bean, cotton, mango, peanut and grapevine. In citrus fruits, the infestation usually forms a ring of scarred tissue around the base of the young fruit, which increases in size as the fruit grows. Injuries to the leaves lead to brownish marks and result in premature ageing. The fruits of navel orange varieties are considered to be the most susceptible to these thrips.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” grid_id=”vc_gid:1763973874563-95e045d04822a0ea9c7225d53a66d366-10″ include=”4835,6020,6746,6735,6742,6022,6024,6421,6420,6422,6418,6736,6741,6737,6744,6734″][vc_separator][vc_column_text css=””]<\/a>Selenothrips rubrocinctus<\/a>\u00a0<\/em><\/strong>\u2013 <\/i>Red-banded Thrips or Cacao Thrips<\/b><\/p>\n

Selenothrips rubrocinctus<\/em>, commonly known as the Red-Banded Thrips, was first described from the West Indies but may have originated in northern South America or Africa. It has spread to other parts of the world and now has a near pan-tropical distribution, occurring in North, Central, and South America, Africa, southern Asia, and Australasia. In Europe it has been reported from Italy and Portugal (Madeira).
\nIt is a significant pest of cacao and mango in the West Indies. Adults and nymphs insert their mouthparts into the epidermis of young leaves, suck sap and cause leaf silvering or browning. The leaf margins crinkle and the leaves become distorted and covered with dark faecal pellets. In heavy infestations the leaves drop off the tree, which may become denuded. Fruit may also be attacked, developing a russet appearance with cracks developing and decay setting in.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” grid_id=”vc_gid:1763973874611-cad1b7801acf258e72c587770c7485c6-1″ include=”7470,7468,7478,7472,7481,7482,7483,7484″][vc_separator][vc_column_text css=””]<\/a>Taeniothrips eucharii <\/em><\/strong><\/a>\u2013 <\/i>Oriental Lily-Flower Thrips<\/b><\/p>\n

T. fuscipennis<\/em> lives and breeds in flowers and on leaves of many different plants and is frequently found on woody species, especially of the family Rosaceae. It is considered a pest of roses, but can also infest other plants in case of high abundance. Cultivated plants under glass are usually damaged when large numbers of this thrips enter greenhouses from outside and reproduce in suitable monocultures.[\/vc_column_text][vc_media_grid style=”load-more” items_per_page=”4″ element_width=”3″ item=”mediaGrid_SlideInTitle” css=”” grid_id=”vc_gid:1763973874792-b65544b5882248e21eaefdb19dd638d4-7″ include=”6450,6451,6449,6446,6442,6453,6443,6447,6452,6444,6448,6445″][vc_separator][vc_column_text]<\/a>Thrips minutissimus<\/em><\/strong><\/a><\/p>\n

Thrips minutissimus <\/em>\u00a0is widespread and common throughout Europe. It occurs on its hostplants in ealry spring and produces only one generation.

Thrips nigropilosus<\/em> is widespread across the northern Palaearctic as far as Japan and locally very common. It has also been introduced into many other parts of the world, e.g. East Africa and New Zealand. T. nigropilosus<\/em> feeds and breeds on many different plants, predominantly however on Asteraceae (Achillea<\/em>, Chrysanthemum<\/em>, Pyrethrum<\/em>, Senecio<\/em>) and is particularly common in grassy places. Occasionally, T. nigropilosus<\/em> can be found as a pest on ornamental as well as crop plants (e.g. basil, mint, cucumber, flax, wheat), both outdoors and in glasshouses.

Thrips palmi<\/em> originates from Southeast Asia, but is now common throughout Asia. Furthermore, it can be found locally in northern Australia and is widespread in different tropical countries, including the Caribbean and southern Florida. In several European countries, T. palmi<\/em> is listed as a quarantine species which is frequently recorded during incoming inspections of plants or plant products. So far, the species has not been able to establish itself permanently in Europe, even though small populations have emerged from time to time (e.g. in the Netherlands, Portugal and Germany).<\/p>\n

In many tropical countries, T. palmi<\/em> is a feared crop pest. Commonly known as the Melon Thrips, T. palmi<\/em> is highly polyphagous and occurs on different cultivated plants, particularly on Cucurbitaceae and Solanaceae. It feeds and breeds on leaves and flowers, where damage is caused by sucking. T. palmi<\/em> is also considered a vector of Tospo viruses (WSMV, GBNV).<\/p>\n

Note: Thrips palmi<\/em> was named after Dr Palm; it is therefore not a thrips that lives on palm trees.

Thrips parvispinus<\/em> comes from South-East Asia but has been introduced into many other parts of the world by plant trade. It is an extremely polyphagous species which feeds on a large variety of plants. Infestation causes severe damage, resulting in wilt and fruit deformation, which may lead to a complete loss of plants or yields. The list of hosts includes ornamentals such as Gardenia<\/em>, Hibiscus<\/em>, Mandevilla<\/em>, Anthurium<\/em>, Hoya<\/em>, Dahlia<\/em>, Chrysanthemum<\/em>, Ruellia<\/em> and Schefflera<\/em>, but also fruits and crops such as Citrus<\/em>, strawberries, aubergines, peppers, cucumbers, beans and courgettes.<\/p>\n
