scirtothrips dorsalis distribution

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. D@b` P�����+�@ Wt*�UK In collaboration with f Cooperative Agricultural Pest Survey, we will organize an active surveillance program to detect the pest in south Florida. 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. Females oviposited most eggs during 10.00 - 04.00 EST. 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. 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. Scientists believe that Scirtothrips dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. World distribution of Scirtothrips dorsalis (SCITDO) Continent Country State Status; Africa: Cote d'Ivoire: Present, restricted distribution General information about Scirtothrips dorsalis (SCITDO) Name Language; Assam thrips: English: chilli thrips: English: flower thrips: English TriCon (a blend of borax, orange oil and biodegradable surfactants) at 391 ml/100 l also reduced S. dorsalis populations on pepper and cotton. A number of nicotinoid and spinosyn insecticides that are highly effective in suppressing chilli thrips populations have been identified. Scirtothrips dorsalis Hood Chilli thrips, castor thrips, assam thrips, yellow tea thrips, strawberry thrips. 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. H��W�r����ü��L-g1����ŢM]"�vR�� Chilli thrips, Scirtothrips dorsalis, are tiny (> 2mm long), cigar-shaped insects. Climatological potential for Scirtothrips dorsalis (Thysanoptera: Thripidae) establishment in the United States (PDF | 450 KB). Scientists believe that S. dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. Also the use of a number of the less harsh biorational chemicals will be developed. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. Scirtothrips dorsalishas been reported from South Africa and the Ivory Coast, and plant quaranti… In Japan, Scirtothrips dorsalis is a pest of tea and citrus (Kodomari 1978). It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. Information will also be disseminated through Pest Alert and EDIS. 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. 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. 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). 2010. The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. Other types of traps will be evaluated. on tea in S. India; S. citri (Moult.) 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. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. Immatures, called larvae, look similar to adults but are even smaller and lack wings. Submitted: June 16th 2012 Reviewed: November 13th 2012 Published: March 14th … Florida Entomologist 91(1):79-86. Sampling indicated S. dorsalis had not established a Two manuscripts will be published in refereed journals on the distribution, bionomics and management of S. dorsalis in the Western Hemisphere. Report progress at the annual meetings of the Florida Entomological Society and the Caribbean Food Crops Society. 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. Seal et al. Their potentiality will be assessed in the laboratory condition. FLORIDA DISTRIBUTION: The current known Florida distribution for Scirtothrips dorsalis is restricted to Palm Beach County. Foliar application of dinotefuran (Venom) provided significant reduction of S. dorsalis on pepper.

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. 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.

Before sharing sensitive information online, make sure you’re on a .gov or .mil site by inspecting your browser’s address (or “location”) bar. In order to manage S. dorsalis, chemical control will be developed using approaches successfully developed against Thrips palmi. The efficient biocontrol agent will be mass reared for inundated release at the beginning of S. dorsalis infestation.

Scirtothrips dorsalis has an aggregated distribution in strawberry fields, with highly infested plants next to uninfested healthy plants (Panthi 2020). The sizes of all of the developmental stages of S. dorsalis were quite similar on all host plants. Origin and Distribution.
