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. The net reproduction rate (Ro) was higher on pepper (11.50) than on rose (9.47). 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). The oviposition period on rose 13.20 d) was longer than on pepper (12.60 d). Scientists believe that Scirtothrips dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. The efficient biocontrol agent will be mass reared for inundated release at the beginning of S. dorsalis infestation. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. Data on various studies will be published as peer-reviewed articles. Determine an efficient but accurate method of trapping S. dorsalis. In order to manage S. dorsalis, chemical control will be developed using approaches successfully developed against Thrips palmi. 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. Submitted: June 16th 2012 Reviewed: November 13th 2012 Published: March 14th … 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 pest's flight activity during the windiest hours of the day facilitates it dispersal by wind. Transmission of tomato spotted wilt virus, the causal agent of bud necrosis of peanut, by Scirtothrips dorsalis and Frankliniella schultzei. The risk Scirtothrips dorsalis (Chilli thrips) would pose to California is evaluated below. The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. This group will also receive preliminary training on chemical control, biological control and disinfestations of commodities to be exported. Thiamethoxam (Actara) was more effective when used as a foliar application than when applied as a soil drench as Platinum. In Japan, S. dorsalis is a pest of tea and citrus (Kodomari 1978). Origin and Distribution. Scirtothrips dorsalis Hood Chilli thrips, castor thrips, assam thrips, yellow tea thrips, strawberry thrips. Sampling indicated S. dorsalis had not established a 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. A serious pest on castor, S. dorsalis infests shoots, leaves, flowers and young fruits. Scientists believe that S. dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. Determine distribution of S. dorsalis in different countries in Caribbean Region. 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. Its biology and management are little known in the agro-ecosystems in western hemisphere. on tea in S. India; S. citri (Moult.) Seal et al. The .gov means it’s official.Federal government websites always use a .gov or .mil domain. Initially yellow sticky cards will be used to trap and monitor S. dorsalis presence and population densities. 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. Species name. Develop sampling method for each host crop depending on the distribution of S. dorsalis and identify feeding and reproductive status on those hosts. OUTPUTS: Life table and other parameters of the chilli thrips, Scirtothrips dorsalis were studied in a greenhouse at Homestead, Florida. Acetamiprid (Assail) applied to the foliage of pepper plants did not provide significant reduction of S. dorsalis in the present study. 1981. On the otherhand it is not clear why the pest is not yet destructive on tropical fruits in Puerto Rico but not in Florida.
