A level of control of more than 90% is fairly common, especially in large areas of crops. After hatching, young larvae penetrate leaves, aerial fruits (like tomato) or stems, on which they feed and develop. The average growth period lasts 12.01 days, therefore they need to go through 4 stages. Egg: It is creamy white, sometimes yellow, turning a darker shade when close to hatching. 2 to 3 weeks before planting, 1 or 2 traps per hectare should be placed to detect the pest and observe its population levels. The use of pheromone products in combination with a yellow delta trap has been recorded in South Africa. It was reported in Nigeria and Zambia [7] in 2016. Later, the pest was reported as Gnorimoschema absoluta , Scrobipalpula absoluta (Povolny), or Scrobipalpuloi… This greatly reduces the population of the pest. A limiting factor of this system could be when there are small plots distributed all around, surrounded by others that have a high level of infestation of Tuta absoluta. [12] Newer compounds such as spinosad,[13] imidacloprid[citation needed], and Bacillus thuringiensis[14] have demonstrated some efficacy in controlling European outbreaks of this moth. Insecticide Resistance in Argentine Populations of, Campos MR, Rodrigues ARS, Silva WM, Silva TBM, Silva VRF, Guedes RNC, et al. 2005. 3). ECONEX WHITE TRIANGULAR without sheets(Code: TA118), ECONEX DISPOSABLE WHITE TRIANGULAR (Code: TA242), ECONEX WHITE TRIANGULAR with captures of Tuta absoluta. No. morphometry of tomato pinworm, Tuta absoluta (Meyrick) at Post Graduate Institute, MPKV, Rahuri (MS) India. A trap controls a surface area between 250 and 500 m2. Pesqui Agropecu Bras 22:129–135. The invasive South American tomato pinworm, Tuta absoluta, continues to spread in Afro-Eurasia and beyond: the new threat to tomato world production. Tuta absoluta is a species of moth in family Gelechiidae known by the common names tomato leafminer, tomato pinworm and South American tomato moth. Damage to tomato plants caused by Tuta absoluta, Damage to ripened tomatoes caused by Tuta absoluta. Apparently, much of the damage to tomatoes attributed to the eggplant leafminer (Gnorimoschema glochinella Zeller) in Mexico and California during the early 1920s was actually inflicted by the tomato pinworm (Morrill 1925). Section of the ECONEX corporate website that allows you access to online information about ECONEX solutions for the biocontrol of other relevant agricultural and forest pests. The geographical distribution of Tuta absoluta spreads throughout South America, Argentina (introduced by Chile in 1964, according to García and Espul, 1982), Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay and Venezuela. MATERIAL AND METHODS Two trials evaluated the resistance of tomato genotypes to tomato pinworm, Tuta absoluta. T. absoluta is mainly associated with tomato plants (Solanum lycopersicum), but it can oviposit and develop on a wide range of cultivated and wild plant species. 2018). In favorable weather conditions eight to ten generations can occur in a single year. It measures 17.5 cm high x 35 cm diameter and the tray has a 3.7 litre capacity. If the level of damage is very low in crops, then the damaged leaves can be manually disposed of. Since its detection in the Mediterranean basin at the end of 2006 and later in other European countries, the South American tomato pinworm, Tuta absoluta (Meyrick), has become a serious threat to tomato crops. This produces the typical damage of a leaf miner and consequently, they wither. In newly infested areas, it is especially … 2020 Jan;76(1):287-295. doi: 10.1002/ps.5513. The South American tomato pinworm, Tuta absoluta(Meyrick), is native to the western Neotropics. In 2011, T. absolutainfested 1.0 M ha of tomato cultivated area (22% of cultivated surface) Now it is a threat to Asia and Africa (South of Sahara) Nigeria has 5% of tomato cultivated in the world The insect was found to be higher Some populations of T. absoluta have developed resistance to organophosphate and pyrethroid pesticides. The larva feeds voraciously upon tomato plants, producing large galleries in leaves, burrowing in stalks, and consuming apical buds and green and ripe fruits. The South American tomato pinworm, Tuta absoluta (Lepidoptera: Gelechiidae), is one of the main insect pests of tomato (Solanum lycopersicum). Tuta absoluta, the South American tomato leafminer (Lepidoptera: Gelechiidae) is a serious pest of tomatoes that has been reported to cause crop losses as high as 80 to 100% in the absence of intensive chemical intervention in areas that it has invaded. Adults usually lay eggs on the underside of leaves or stems, and to a lesser extent on fruits. This dangerous pest favors tomato (Solanum lycopersicum) and sometimes potato (S. tuberosum). Once the larva emerges, it starts walking and finds its penetration point. The head, thorax and palps are ash grey with dark shades. Tomato is the main host plant, but T. absoluta also attacks other crop plants of the nightshade family, including potato, eggplant, pepino, pepper and tobacco. Larva: The prothoracic shield has a dark stripe on its backside. One important factor is the size of the crop. Moreover, no studies have looked at its overwintering survival in sub‐Saharan Africa. Recently, this pest has been identified from several districts of Nepal [8] It is now severely infested in Myanmar, especially in tropical tomato growing areas such as Mandalay, Sagaing, Monywa. The combined use of, https://www.bloomberg.com/news/articles/2016-06-08/africa-s-got-a-tomato-problem-miner-grubs-are-wiping-them-out, "UOG watches for moth, bacteria that attack nightshade plants", https://doi.org/10.1371/journal.pone.0103235, http://www.cctec.cornell.edu/technology/products/iscalure-web.pdf, Video "Living with Tuta absoluta" Proposed Management Strategy (in English), Video "Living with Tuta absoluta" Proposed Management Strategy (in Arabic), https://en.wikipedia.org/w/index.php?title=Tuta_absoluta&oldid=1000344324, Short description is different from Wikidata, Articles with unsourced statements from September 2011, Taxonbars with automatically added original combinations, Creative Commons Attribution-ShareAlike License, This page was last edited on 14 January 2021, at 18:54. (150 packs x 20 units), PACKAGING – ECONEX TUTA ABSOLUTA 0.80 MG 60 DAYS, PACKAGING – ECONEX TUTA ABSOLUTA 1 MG 90 DAYS, Box of 3.000 units. 2018. The average growth period for male pupae is 7.80 days and for female pupae 6.72 days. Tomato leaf moth has a life cycle of 29 to 38 days depending on the temperature. In Africa, T. absoluta moved from Egypt to reach Sudan, South Sudan and Ethiopia from the east and to reach the Senegal from the west. [19], Clarke JF (1962) New species of microlepidoptera from Japan. For mass trapping, the following wet traps are recommended: ECONEX WATER TRAP or ECONEX WATER TRAP (ECO) because of their effectiveness, large capacity and low maintenance. In this wet trap, you have to pour water into the tray and we recommend adding a film of oil to the water to increase the captures. Despite some important basic rules for an effective control of Tuta absoluta, every farmer or specialist has to find their own system of control to achieve it. ECONEX TUTA ABSOUTA 0.50 MG 60 DAYS packaging and pheromone diffuser (Code: VA220), ECONEX TUTA ABSOLUTA 0.80 MG 60 DAYS packaging and pheromone diffuser (Code: VA275), ECONEX TUTA ABSOLUTA 1 MG 90 DAYS packaging and pheromone diffuser (Code: VA328). They can experiment with this system, even establishing their own tolerance thresholds. They are nocturnal, remaining hidden amongst the leaves during the day. If it is left uncontrolled, it is a destructive pest of tomato fruit and plants causing yield losses between 80 to 100 % (Desneux et al. T. absoluta is a key insect pest of tomato which also known as tomato pinworm of Southern America (Brevault et al. In this wet trap, you have to pour water into the tray and we recommend adding a film of oil to the water to increase the captures. The newly introduced pest from south America finding the shores of the Mediterranean a perfect new home where it can breed between 10-12 generations a year. The trap ECONEX DISPOSABLE WHITE TRIANGULAR is coated on its inner face with a layer of contact adhesive, solvent free, for the retention of the insects. The tomato pinworm, Tuta absoluta (Meyrick) (Gelechiidae: Lepidoptera), is an introduced serious pest of tomato in India. The tomato pinworm Tuta absoluta (Meyrick) is a devastating pest of tomato. Close the greenhouses with netting (6 x 9 threads/cm. Pupae (length: 5–6 mm) are cylindrical in shape and greenish when just formed becoming darker in color as they are near adult emergence. After invading Spain in 2006, it spread rapidly throughout Afro-Eurasia and has become a major threat to world tomato production. Tuta absoluta Tuta absoluta (Meyrick) is a serious tomato pest that also damages aubergines, potatoes and can use other Solanaceae as host plants. Climate change characteristics of cold air process in the Yili Valley in recent 56 years. When the attacks are severe, the damaged leaves look burnt, which could be confused with disease. Life expectancy for males is 27 days and for females is 24 days. This ensures that any remaining larvae or chrysalis will be eliminated. [2] Its life-cycle comprises four development stages: egg, larva, pupa and adult. Tuta absoluta is not present in Andean regions in altitudes above 1.000 m because the low temperatures are a limiting factor for its survival (Notz, 1992). It is well known as a serious pest of tomato crops in Europe, Africa, western Asia and South and Central America. Tuta absoluta larva inside the stem of a tomato. Both traps stand out above all for their simplicity of use, and will be operative until pheromone depletion or saturation of the sheet or adhesive surface. Recently Tuta absoluta considered to be a serious threat to tomato production in Mediterranean region. To obtain good control of the Tuta absoluta it is advisable to combine two methods: detection and monitoring; and mass trapping. After invading Spain in 2006, it spread rapidly throughout Afro-Eurasia and has become a major threat to world tomato production.
