Thiamethoxam (Actara) was more effective when used as a foliar application than when applied as a soil drench as Platinum. The pest's flight activity during the windiest hours of the day facilitates it dispersal by wind. 2010. By Vivek Kumar, Garima Kakkar, Cindy L. McKenzie, Dakshina R. Seal and Lance S. Osborne. Neither adult nor larval populations were substantially suppressed by any of the following pyrethroids: cyfluthrin (Baythroid), zeta-cypermethrin (Mustang), cyhalothrin-lambda (Warrior), and esfenvalerate (Asana XL). Scirtothrips dorsalis was first detected in Highlands County, Florida, in 1991. The genus Scirtothrips currently includes 100 listed species from various parts of the world. In addition we were unable to pursue much of the planned research on biological controlof S. dorsalis. In 2008 S. dorsalis was found in the Greater Caribbean Region in Barbados, Florida, Jamaica, Puerto Rico, Texas, Trinidad & Tobago, St. Lucia, St. Vincent, Venezuela and Suriname, but not in the French West Indies, Guyana, Hispaniola and Costa Rica. Foliar application of dinotefuran (Venom) provided significant reduction of S. dorsalis on pepper. Also the use of a number of the less harsh biorational chemicals will be developed. Scirtothrips dorsalis Hood.. Taxonomic position: Insecta, Hemimetabola, Thysanoptera, Terebrantia, Thripidae.. A Ribosomal DNA ITS2 marker for the identification of S. dorsalis is available.. Common name: Chilli thrips, yellow tea thrips.. Geographical distribution: The Far East, Oceania, South Africa, Israel, the Caribbean and southern USA.Distribution Maps of Plant Pests, Map 475. Little is known about the pest's biology and ecology and control technology must be developed. Information will also be disseminated through Pest Alert and EDIS. The adults are pale in color with black, feathery wings and dark spots forming incomplete stripes on the top of the abdomen. Its biology and management are little known in the agro-ecosystems in western hemisphere. None of the pyrethroid insecticides investigated provided effective control of this pest. Main content area. The net reproduction rate (Ro) was higher on pepper (11.50) than on rose (9.47). Adults were most active during 10.00 - 04.00 EST. Information obtained on life table and demographic parameters and on daily activity patterns of the pest provides the foundation for understanding the capacity of the pest to rapidly build large large populations on hosts such as cotton, peanut, pepper, and ornamentals such as lisianthus. Their potentiality will be assessed in the laboratory condition. Abstract. D@b` P�����+�@ Wt*�UK It was introduced to Israel and the Caribbean area and is probably spreading in the world by horticultural trade. on tea in S. India; S. citri (Moult.) Biology and distribution. For the purpose of studying distribution patterns of S. 2dorsalis, an area of 332 m of each field was divided into 60 equal plots, each 4.6 m long and 1.2 m wide, and each plot contained 5 pepper plants. Authoritative taxonomic determinations were provided by Dr. G. B. Edwards, Florida Department of Agriculture and Consumer Services. Every year, one meeting will be organized in one Caribbean country to share data with various stakeholders including the Caribbean Community Secretariat (CARICOM), USDA-APHIS and the Department of Homeland Security. Determine distribution of S. dorsalis in different countries in Caribbean Region. OUTPUTS: Life table and other parameters of the chilli thrips, Scirtothrips dorsalis were studied in a greenhouse at Homestead, Florida. In each country a group of people will be trained to collect and identify S. dorsalis, and prepare specimens for microscopic examination. TriCon (a blend of borax, orange oil and biodegradable surfactants) at 391 ml/100 l also reduced S. dorsalis populations on pepper and cotton.

Osborne, Mid-Florida Research & Education Center, Apopka, FL, Dr. Amanda Hodges, Entomology and Nematology Department, University of Florida, Gainesville, FL took the lead in educating county agents and growers in Florida and in assembling host records. This may provide information on the feeding and reproductive behavior of S. dorsalis on that species of plant. Within this genus, Scirtothrips dorsalis Hood is a significant pest of various economically important vegetable, ornamental and fruit crops in southern and eastern Asia, Oceania and ... Venette and Davis [28] projected the potential geographic distribution of S. dorsalis in North America. Report progress at the annual meetings of the Florida Entomological Society and the Caribbean Food Crops Society. Hosts: polyphagous. World distribution of Scirtothrips dorsalis (SCITDO) Continent Country State Status; Africa: Cote d'Ivoire: Present, restricted distribution Mean numbers of larvae per plant were significantly higher on pepper and on the rose cultivar, Knockout, than on bean, eggplant, squash and tomato. In Japan, S. dorsalis is a pest of tea and citrus (Kodomari 1978). Larval duration was longer than pupal duration irrespective of the host plant. Larvae and adults of S. dorsalis were found on … Seal et al. Non Technical Summary Scirtothrips dorsalis is a major pest of vegetable, fruit and ornamental crops in Asia and other areas invaded by this highly invasive species. The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. Improved sampling methods will be developed to augment direct relative sampling, which entails the collection of parts of plants assess the presence of this insect on host plants. Florida Entomologist 91(1):79-86. It is abundant on sacred lotus in Thailand (Mound and Palmer 1981), and on chilli peppers in India (Ramakrishna Ayyar 1932, Ramakrishna Ayyar and Subbiah 1935), where it is also a serious pest of peanuts (Amin 1979, 1980). Bailey (1945) and Priesner (1932), in their work on Scirtothrips, mention S. dorsalis as a distinct species. The entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae proved to be effective in suppressing the pest, as did Tricon, a mixture of natural products.This information has significant bearing on the efforts of the fruit, ornamental and vegetable industries to protect their crops from damage by S. dorsalis infestations. Distribution of chilli thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae), in pepper fields and pepper plants on St. Vincent Immatures, called larvae, look similar to adults but are even smaller and lack wings. Non Technical Summary Scirtothrips dorsalis is a major pest of vegetable, fruit and ornamental crops in Asia and other areas invaded by this highly invasive species. Adult S. dorsalis were abundant on pepper and rose and less so on eggplant, and absent on bean, squash and tomato. Moreover, this information will enable growers to use neonicotinoid insecticides more selectively to avoid the decimation of populations of natural enemies.

Reddy, and A.M. Ghanekar. %PDF-1.3 %���� Dr. Ciomperlik also surveyed the infestations found in the Rio Grand Valley and at Houston, TX. Environmental Entomology 39(5):1389-1398. A list of candidate insecticides has been prepared. During the early season, S. dorsalis appear to colonize a relatively small number of young plants in a field, and since adults move slowly among plants, populations become highly aggregated. Since chilli thrips is of limited distribution in the U.S. and concerns exist for the possibility of new biotype and/or species introductions, USDA-APHIS does not allow plant material infested with chilli thrips to arrive at U.S. ports of entry. FLORIDA DISTRIBUTION: The current known Florida distribution for Scirtothrips dorsalis is restricted to Palm Beach County. Initially yellow sticky cards will be used to trap and monitor S. dorsalis presence and population densities. Notes are given on the host range, distribution and recognition of the ten species of Scirtothrips recorded as pests: S. aurantii Faure on citrus in South Africa and bananas in Yemen; S. bispinosus (Bagn.) Scirtothrips dorsalis Hood. PROJECT MODIFICATIONS: Since we received funding only for the first two years of this study, we had to curtail travel in the Caribbean Region to determine the current geographic distribution of the pests and how damage by the pest is manifested in different geographical settings. Scirtothrips dorsalis Hood, 1919. The oviposition period on rose 13.20 d) was longer than on pepper (12.60 d). The duration of the immature stages varied within a narrow range on all host crops. Scirtothrips dorsalis has an aggregated distribution in strawberry fields, with highly infested plants next to uninfested healthy plants (Panthi 2020). Metarhizium anisopliae (green muscardine fungus) at 227 ml/100 l effectively reduced S. dorsalis adults on cotton. The chilli thrips, Scirtothrips dorsalis Hood, is a serious pest of numerous important vegetable and ... number and distribution of the antennal sensilla in males and females. Submitted: June 16th 2012 Reviewed: November 13th 2012 Published: March 14th … The population density was highest during March through June with a peak in April and lowest during January and February. S. dorsalis has the wing cilia straight not wavy, but although the species is now established in Florida and the Caribbean, it has not yet been found in California. Family name. Scirtothrips dorsalis is a widespread pest, described as a new species by Hood in 1919 from 34 females collected in India on castor and chillies and subsequently recorded by Ramakrishna Ayyar (1928) and Shumsher Singh (1944). On `Jalapeno' pepper plants BotaniGard ES (Beauveria bassiana) at 0.5 l/100 l at weekly intervals significantly reduced mean numbers of S. dorsalis adults and larvae. PROGRESS: 2005/09 TO 2008/09 All treatments of M. anisopliae and B. bassiana significantly reduced populations of chilli thrips larvae, and were comparable to spinosad (Spintor), which provides excellent control of S. dorsalis larvae. For the purpose of studying distribution patterns of S. dorsalis, an area of 332 m2 of each field was divided into 60 equal plots, each 4.6 m long and 1.2 m wide, and each plot contained 5 pepper plants. Seal et al. In order to manage S. dorsalis, chemical control will be developed using approaches successfully developed against Thrips palmi. Climatological potential for Scirtothrips dorsalis (Thysanoptera: Thripidae) establishment in the United States (PDF | 450 KB). Seal, D.R., W. Klassen, and V. Kumar. The innate capacity for natural increase (rm) and the mean duration of a generation (T) of S. dorsalis did not differ between those reared on pepper or on rose. Disseminate information to research, extension and regulatory personnel, and also to growers in Florida and Caribbean countries. The efficacy of some bio-rational insecticides, such as neem, neem oil, garlic barrier and hot pepper wax, will also be evaluated in various crop systems. Data on various studies will be published as peer-reviewed articles. Determination host distribution will be informed by previous studies conducted by various researchers in Asia.

Various native biological agents will be identified in each country of Caribbean Basin. On the otherhand it is not clear why the pest is not yet destructive on tropical fruits in Puerto Rico but not in Florida. In this study, the morphology, distribution, and ultrastructure of the antennal sensilla of the S. dorsalis were examined by using scanning and transmission electron microscopy. A number of nicotinoid and spinosyn insecticides that are highly effective in suppressing chilli thrips populations have been identified. We investigated distribution patterns of S. dorsalis in fields and plants of ‘Scotch Bonnet’ pepper, Capsicum chinense Jacq., on St. Vincent in 2004 and 2005. APPROACH: To determine the pest's geographical distribution the Ministry of Agriculture of each Caribbean country or Territory will be contacted for permission to conduct a survey for S. dorsalis, or to assist qualified personnel in a given country to carry out the survey. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. Consequences of Introduction: 1) Climate/Host Interaction: The present distribution of Scirtothrips dorsalis corresponds to USDA plant hardiness zones 8-12, indicating that it is likely to find a favorable climate in most of California. TARGET AUDIENCES: The target audiences include professional entomologists in educational, research and regulatory agencies and in private firms which supply advisory services or chemical and biological controls to growers. Sessions may be organized at the annual meetings of the Caribbean Food Crops Society and the Florida Entomological Society. The presence and distribution of Scirtothrips dorsalis was reported in Colombia in the Andean, Caribbean, and Orinoquia regions, from 0 to 1,200 meters of altitude (MASL) in the warm climate zone, with less than 2,000 mm rainfall per year and a temperature above 24°C, which corresponds to the tropical dry forest life zone (TDF). Scirtothrips dorsalishas been reported from South Africa and th… It is abundant on sacred lotus in Thailand (Mound and Palmer 1981), and on chilli peppers in India (Ramakrishna Ayyar 1932, Ramakrishna Ayyar and Subbiah 1935), where it is also a serious pest of peanuts (Amin 1979, 1980). Transmission of tomato spotted wilt virus, the causal agent of bud necrosis of peanut, by Scirtothrips dorsalis and Frankliniella schultzei. Scirtothrips dorsalis Hood is a significant pest of various vegetable, ornamental, and fruit crops. Develop a control method using conventional insecticides labeled for use on fruits, ornamentals and vegetable. General information about Scirtothrips dorsalis (SCITDO) Name Language; Assam thrips: English: chilli thrips: English: flower thrips: English Sampling indicated S. dorsalis had not established a The longevities of both males and females were greater on pepper than on rose. The presence and distribution of Scirtothrips dorsalis was reported in Colombia in the Andean, Caribbean, and Orinoquia regions, from 0 to 1,200 meters of altitude (MASL) in the warm climate zone, with less than 2,000 mm rainfall per year and a temperature above 24°C, which corresponds to the tropical dry forest life zone (TDF). H��W�r����ü��L-g1����ŢM]"�vR�� Chilli thrips, Scirtothrips dorsalis, are tiny (> 2mm long), cigar-shaped insects. Females oviposited most eggs during 10.00 - 04.00 EST. Scirtothrips dorsalis Hood Chilli thrips, castor thrips, assam thrips, yellow tea thrips, strawberry thrips. The sizes of all of the developmental stages of S. dorsalis were quite similar on all host plants. Osborne, C. Palmer, C. Regelburgge, L. Schmale and D. Schuble. PARTICIPANTS: Dr. Matt A. Ciomperlik, Entomologist, USDA,APHIS,PPQ, Pest Detection Diagnostics and Management Laboratory, Moore Air Base, Edinburg, TX was very helpful in conducting studies on St. Vincent, and in conducting surveys for the chilli thrips in Barbados, Guyana and Suriname. The https:// means all transmitted data is encrypted — in other words, any information or browsing history that you provide is transmitted securely. Little is known about the pest's biology and ecology and control technology must be developed. The preoviposition period on pepper (3.60 d) was the same as on rose. Synonyms: Caliothrips minutissimus Faure, 1962 Scirtothrips padmae Ramakrishna, 1942 Scirtothrips andreae Hood, 1935 Neophysopus fragariae Girault, 1927 Anaphothrips oligochaetus Karny, 1925 Anaphothrips andreae Karny, 1925 Scirtothrips dorsalis Hood, 1919 Heliothrips minutissimus Bagnall, 1919 . Other types of traps will be evaluated. The number and distribution of setae on the median area of the pronotum are known to be variable within some Scirtothrips species, as well as in some other Thripidae (O'Donnell & Mound 2016). These objectives will be conducted in close cooperation with CARDI scientists and personnel from Ministry of Agriculture in each country, especially St. Vincent and the Grenadines and St. Lucia, where most of the work on chemical, biorational cultural and biological control will be conducted. Since in Florida, the pest is particularly troublesome on landscape plants in urban settings, master gardners, county agents and employees of parks departments need to become familiar with S. dorsalis and how to cope with it. This site is also protected by an SSL (Secure Sockets Layer) certificate that’s been signed by the U.S. government. Not recorded from New Zealand but considered a high risk potential invader, this species is widespread from Pakistan to Japan and Australia, and also introduced in Israel, the Carribean area, and parts of South America. Mean numbers of pupae were also higher on pepper and Knockout rose than on these other hosts. Click to download a PDF version of this publication. This group will also receive preliminary training on chemical control, biological control and disinfestations of commodities to be exported. Described from Australia (N. fragariae), India (S. dorsalis, S. padmae, H. minutissimus) and Indonesia (A. andreae).Distribution: Originated from Southeast Asia S. dorsalis is widespread between Pakistan, Japan and Australia. As is typical of species in the genus Scirtothrips, eggs are laid in the youngest tissues of plants, and feeding by adults and larvae can result in extensive cell damage to these developing tissues, leading to leaf and fruit distortion, and flower fall.
