Dr. Adam Silagyi, Cooperative Agricultural Pest Surveys, supervised surveys for S. dorsalis in Florida. 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. Scirtothrips dorsalis Hood Chilli thrips, castor thrips, assam thrips, yellow tea thrips, strawberry thrips. A list of candidate insecticides has been prepared. The risk Scirtothrips dorsalis (Chilli thrips) would pose to California is evaluated below. The https:// means all transmitted data is encrypted — in other words, any information or browsing history that you provide is transmitted securely. 1981. This site is also protected by an SSL (Secure Sockets Layer) certificate that’s been signed by the U.S. government. Data on various studies will be published as peer-reviewed articles. 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. Develop a control method using conventional insecticides labeled for use on fruits, ornamentals and vegetable. 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. 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). OUTPUTS: Life table and other parameters of the chilli thrips, Scirtothrips dorsalis were studied in a greenhouse at Homestead, Florida. Immatures, called larvae, look similar to adults but are even smaller and lack wings. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. Environmental Entomology 39(5):1389-1398. 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. In Japan, S. dorsalis is a pest of tea and citrus (Kodomari 1978). Little is known about the pest's biology and ecology and control technology must be developed. Adults were most active during 10.00 - 04.00 EST. Within 'Scotch Bonnet' Pepper Plant Distribution 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. 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. 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. Sessions may be organized at the annual meetings of the Caribbean Food Crops Society and the Florida Entomological Society. Scirtothrips dorsalis Hood is a significant pest of various vegetable, ornamental, and fruit crops. The genus Scirtothrips currently includes 100 listed species from various parts of the world. 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. 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. 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. Within `Scotch Bonnet’ Pepper Plant Distribution The preoviposition period on pepper (3.60 d) was the same as on rose. PROGRESS: 2005/09 TO 2008/09 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. %PDF-1.3 %���� Abstract. ߶)DЍ�����K]&�@�sd�=?9�ܵ��=ߏ��z�p���~b�]�2G����O��)}œN�'��M-_����Lqb��C=��zX��6^1�+���2ﾏw>],.o�9�'A�$u����9A��=$h©}X�b@}��}$����e���.L�(/��dO�*��8&���m��c��Gm�y��Wh�Q�j�>� �e�[�c�Gi�cfY����MT�Q���Ȃ%�6�2o��CF?`�?R���-,� ͭF'�^Q���vC��_�z����y��փ����4K�'B'Q�4Aq�N���W���&H�u�md. Imidacloprid provided significant reduction of S.dorsalis when applied as Admire as a soil drench or when applied as Provado to the foliage. Distribution of Scirtothrips Dorsalis in the Carribbean Region and the Development of Chemical and Biological Methods to Manage this Pest. 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. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. The sizes of all of the developmental stages of S. dorsalis were quite similar on all host plants. Two manuscripts will be published in refereed journals on the distribution, bionomics and management of S. dorsalis in the Western Hemisphere. The sensory abilities of S. dorsalis are poorly understood although the antennae of adult are known to possess important sensory structures in orther insects. 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. In addition we were unable to pursue much of the planned research on biological controlof S. dorsalis. Determine distribution of S. dorsalis in different countries in Caribbean Region. 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 . The .gov means it’s official.Federal government websites always use a .gov or .mil domain. This may provide information on the feeding and reproductive behavior of S. dorsalis on that species of plant. 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. In order to manage S. dorsalis, chemical control will be developed using approaches successfully developed against Thrips palmi. 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. Distribution of Scirtothrips Dorsalis in the Carribbean Region and the Development of Chemical and Biological Methods to Manage this Pest Investigators Seal, Dakshina Institutions University of Florida Start date 2005 End date 2008 Objective. Biology and distribution. 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. 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. The longevities of both males and females were greater on pepper than on rose. Its biology and management are little known in the agro-ecosystems in western hemisphere. Larval duration was longer than pupal duration irrespective of the host plant. This group will also receive preliminary training on chemical control, biological control and disinfestations of commodities to be exported. Origin and Distribution. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. Information will also be disseminated through Pest Alert and EDIS. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. Foliar application of dinotefuran (Venom) provided significant reduction of S. dorsalis on pepper. A number of potentially effective predators have already been identified, and their effectiveness in the field will be assessed. The use of biocontrol agents will be investigated. This knowledge will be used to identify those hosts in various countries of Caribbean Basin. Attempts will be made to facilitate adoption of this proven control technologies in the management of fruits, ornamental and vegetable production system. An Overview of Chilli Thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae) Biology, Distribution and Management. The pest's flight activity during the windiest hours of the day facilitates it dispersal by wind. Scientists believe that S. dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. 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. Seal et al. The efficient biocontrol agent will be mass reared for inundated release at the beginning of S. dorsalis infestation. General information about Scirtothrips dorsalis (SCITDO) Name Language; Assam thrips: English: chilli thrips: English: flower thrips: English Distribution data. 2 0 obj << /Length 4445 /Filter /FlateDecode >> stream Acetamiprid (Assail) applied to the foliage of pepper plants did not provide significant reduction of S. dorsalis in the present study. A serious pest on castor, S. dorsalis infests shoots, leaves, flowers and young fruits. Distribution of chilli thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae), in pepper fields and pepper plants on St. Vincent 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. 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.
