scirtothrips dorsalis distribution

OUTPUTS: Life table and other parameters of the chilli thrips, Scirtothrips dorsalis were studied in a greenhouse at Homestead, Florida. Mean numbers of pupae were also higher on pepper and Knockout rose than on these other hosts. This site is also protected by an SSL (Secure Sockets Layer) certificate that’s been signed by the U.S. government. 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. In collaboration with f Cooperative Agricultural Pest Survey, we will organize an active surveillance program to detect the pest in south Florida. on tea in S. India; S. citri (Moult.) 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. The use of biocontrol agents will be investigated. A serious pest on castor, S. dorsalis infests shoots, leaves, flowers and young fruits. 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. Dr. Ciomperlik also surveyed the infestations found in the Rio Grand Valley and at Houston, TX. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. Two manuscripts will be published in refereed journals on the distribution, bionomics and management of S. dorsalis in the Western Hemisphere. 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). 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. Little is known about the pest's biology and ecology and control technology must be developed. TriCon (a blend of borax, orange oil and biodegradable surfactants) at 391 ml/100 l also reduced S. dorsalis populations on pepper and cotton. 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. 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. 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. Seal et al. Disseminate information to research, extension and regulatory personnel, and also to growers in Florida and Caribbean countries. Click to download a PDF version of this publication. Within 'Scotch Bonnet' Pepper Plant Distribution 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. The duration of the immature stages varied within a narrow range on all host crops. Larval duration was longer than pupal duration irrespective of the host plant. Attempts will be made to facilitate adoption of this proven control technologies in the management of fruits, ornamental and vegetable production system. 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. Imidacloprid provided significant reduction of S.dorsalis when applied as Admire as a soil drench or when applied as Provado to the foliage.

Information will also be disseminated through Pest Alert and EDIS. Thiamethoxam (Actara) was more effective when used as a foliar application than when applied as a soil drench as Platinum. Various native biological agents will be identified in each country of Caribbean Basin. Scientists believe that Scirtothrips dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. In order to manage S. dorsalis, chemical control will be developed using approaches successfully developed against Thrips palmi. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. 1981. The .gov means it’s official.Federal government websites always use a .gov or .mil domain. Other types of traps will be evaluated. General information about Scirtothrips dorsalis (SCITDO) Name Language; Assam thrips: English: chilli thrips: English: flower thrips: English Scirtothrips dorsalis Hood, 1919. Scirtothrips dorsalishas been reported from South Africa and the Ivory Coast, and plant quaranti… 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. FLORIDA DISTRIBUTION: The current known Florida distribution for Scirtothrips dorsalis is restricted to Palm Beach County. Seal, D.R., W. Klassen, and V. Kumar. The net reproduction rate (Ro) was higher on pepper (11.50) than on rose (9.47). This group will also receive preliminary training on chemical control, biological control and disinfestations of commodities to be exported. 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. H��W�r����ü��L-g1����ŢM]"�vR�� Determine distribution of S. dorsalis in different countries in Caribbean Region.
