This knowledge will be used to identify those hosts in various countries of Caribbean Basin. Thiamethoxam (Actara) was more effective when used as a foliar application than when applied as a soil drench as Platinum. Family name. Florida Entomologist 91(1):79-86. 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. By Vivek Kumar, Garima Kakkar, Cindy L. McKenzie, Dakshina R. Seal and Lance S. Osborne. Within 'Scotch Bonnet' Pepper Plant Distribution A standard trapping method will be developed, which can be used by others in different locations. The preoviposition period on pepper (3.60 d) was the same as on rose. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. 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. IMPACT: 2005/09 TO 2008/09 This group will also receive preliminary training on chemical control, biological control and disinfestations of commodities to be exported. Transmission of tomato spotted wilt virus, the causal agent of bud necrosis of peanut, by Scirtothrips dorsalis and Frankliniella schultzei. Determine distribution of S. dorsalis in different countries in Caribbean Region. Develop a control method using conventional insecticides labeled for use on fruits, ornamentals and vegetable. Scirtothrips dorsalis Hood is a significant pest of various vegetable, ornamental, and fruit crops. Dr. Ciomperlik also surveyed the infestations found in the Rio Grand Valley and at Houston, TX. 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. Mean numbers of pupae were also higher on pepper and Knockout rose than on these other hosts. 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. Dr. Lance S. 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. 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. 2 0 obj << /Length 4445 /Filter /FlateDecode >> stream General information about Scirtothrips dorsalis (SCITDO) Name Language; Assam thrips: English: chilli thrips: English: flower thrips: English 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. 2010. Sessions may be organized at the annual meetings of the Caribbean Food Crops Society and the Florida Entomological Society. Determination host distribution will be informed by previous studies conducted by various researchers in Asia. Scirtothrips dorsalis Hood Chilli thrips, castor thrips, assam thrips, yellow tea thrips, strawberry thrips. Abstract. 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. Authoritative taxonomic determinations were provided by Dr. G. B. Edwards, Florida Department of Agriculture and Consumer Services.

It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. In each country a group of people will be trained to collect and identify S. dorsalis, and prepare specimens for microscopic examination. 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. Dr. Adam Silagyi, Cooperative Agricultural Pest Surveys, supervised surveys for S. dorsalis in Florida. Information will also be disseminated through Pest Alert and EDIS. 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. In addition we were unable to pursue much of the planned research on biological controlof S. dorsalis. The longevities of both males and females were greater on pepper than on rose. The oviposition period on rose 13.20 d) was longer than on pepper (12.60 d). In Japan, Scirtothrips dorsalis is a pest of tea and citrus (Kodomari 1978). Osborne, C. Palmer, C. Regelburgge, L. Schmale and D. Schuble. Climatological potential for Scirtothrips dorsalis (Thysanoptera: Thripidae) establishment in the United States (PDF | 450 KB). Distribution data. Distribution of Scirtothrips Dorsalis in the Carribbean Region and the Development of Chemical and Biological Methods to Manage this Pest. The net reproduction rate (Ro) was higher on pepper (11.50) than on rose (9.47). : Scirtothrips dorsalis distribution in pepper fields 313 tubing. 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. Initially yellow sticky cards will be used to trap and monitor S. dorsalis presence and population densities. Original name and synonyms Its biology and management are little known in the agro-ecosystems in western hemisphere. 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. 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. Sampling indicated S. dorsalis had not established a Mean numbers of larvae per plant were significantly higher on pepper and on the rose cultivar, Knockout, than on bean, eggplant, squash and tomato. 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. Two manuscripts will be published in refereed journals on the distribution, bionomics and management of S. dorsalis in the Western Hemisphere. 1981. The .gov means it’s official.Federal government websites always use a .gov or .mil domain. A list of candidate insecticides has been prepared. World distribution of Scirtothrips dorsalis (SCITDO) Continent Country State Status; Africa: Cote d'Ivoire: Present, restricted distribution Also the use of a number of the less harsh biorational chemicals will be developed. On the otherhand it is not clear why the pest is not yet destructive on tropical fruits in Puerto Rico but not in Florida. %PDF-1.3 %���� Metarhizium anisopliae (green muscardine fungus) at 227 ml/100 l effectively reduced S. dorsalis adults on cotton. In collaboration with f Cooperative Agricultural Pest Survey, we will organize an active surveillance program to detect the pest in south Florida. 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. on tea in S. India; S. citri (Moult.) Various native biological agents will be identified in each country of Caribbean Basin. 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. Hosts: polyphagous. Environmental Entomology 39(5):1389-1398. Species name. 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). Adult S. dorsalis were abundant on pepper and rose and less so on eggplant, and absent on bean, squash and tomato. 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. Attempts will be made to facilitate adoption of this proven control technologies in the management of fruits, ornamental and vegetable production system. Bailey (1945) and Priesner (1932), in their work on Scirtothrips, mention S. dorsalis as a distinct species. Before sharing sensitive information online, make sure you’re on a .gov or .mil site by inspecting your browser’s address (or “location”) bar. Acetamiprid (Assail) applied to the foliage of pepper plants did not provide significant reduction of S. dorsalis in the present study. 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). Seal et al. 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. TriCon (a blend of borax, orange oil and biodegradable surfactants) at 391 ml/100 l also reduced S. dorsalis populations on pepper and cotton. Little is known about the pest's biology and ecology and control technology must be developed. 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. The pest's flight activity during the windiest hours of the day facilitates it dispersal by wind. 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. Submitted: June 16th 2012 Reviewed: November 13th 2012 Published: March 14th … THRIPIDAE, THRIPINAE. 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. Main content area. The efficient biocontrol agent will be mass reared for inundated release at the beginning of S. dorsalis infestation. Larval duration was longer than pupal duration irrespective of the host plant. The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. Data on various studies will be published as peer-reviewed articles. This may provide information on the feeding and reproductive behavior of S. dorsalis on that species of plant. 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. 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. The adults are pale in color with black, feathery wings and dark spots forming incomplete stripes on the top of the abdomen. Adults were most active during 10.00 - 04.00 EST. In order to manage S. dorsalis, chemical control will be developed using approaches successfully developed against Thrips palmi. 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). Scirtothrips dorsalis has an aggregated distribution in strawberry fields, with highly infested plants next to uninfested healthy plants (Panthi 2020). Distribution of chilli thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae), in pepper fields and pepper plants on St. Vincent 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. The use of biocontrol agents will be investigated. D@b` P�����+�@ Wt*�UK Seal et al. A number of potentially effective predators have already been identified, and their effectiveness in the field will be assessed.

FLORIDA DISTRIBUTION: The current known Florida distribution for Scirtothrips dorsalis is restricted to Palm Beach County. Scirtothrips dorsalis Hood. Biology and distribution. 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 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). Imidacloprid provided significant reduction of S.dorsalis when applied as Admire as a soil drench or when applied as Provado to the foliage. 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. 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. Reddy, and A.M. Ghanekar. Gain the goodwill and cooperation of agricultural personnel in each country, present talks and poster on S. dorsalis damage and train them with necessary knowledge on pest management to continue further studies on sampling, insecticide evaluation and biocontrol. ��d")w�,/�,jY�/����[�G�(HHT� �ߎ�K��,Vq^f�sofy$1��E�Ǐ�2�R�dm�QN~���Ol�r�F���ߖ��x�q�(h�:6gd��}1[,f�~\��n��9����3�����av�����р>^qC��ġ��%ٟv����S�-�g����U���{XL�E����)�� �Z���a��;d�(�w�I�@�`]Lo��o W{g��/cC���_��_>�����bQ���^�`l�x��>R�j�9՛����rA���r̸=���ݞ_�.�n��#���0d��C����%�,�BG/t�����*-nV�o̖�INlϧ� �ǵ(]N��}��g����‰`��׈�Z��úۧ�I� ���dJ�y'p����ũ�N|vw���g?�ÇO The sizes of all of the developmental stages of S. dorsalis were quite similar on all host plants.

Moreover, this information will enable growers to use neonicotinoid insecticides more selectively to avoid the decimation of populations of natural enemies. The risk Scirtothrips dorsalis (Chilli thrips) would pose to California is evaluated below. 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. Their potentiality will be assessed in the laboratory condition. Scientists believe that S. dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. Larvae and adults of S. dorsalis were found on … Scirtothrips dorsalis was first detected in Highlands County, Florida, in 1991. Foliar application of dinotefuran (Venom) provided significant reduction of S. dorsalis on pepper. 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. The duration of the immature stages varied within a narrow range on all host crops. Biological parameters of Scirtothrips dorsalis (Thysanoptera: Thripidae) on selected hosts.
