The https:// means all transmitted data is encrypted — in other words, any information or browsing history that you provide is transmitted securely. Scirtothrips dorsalis has an aggregated distribution in strawberry fields, with highly infested plants next to uninfested healthy plants (Panthi 2020). 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 . Sampling indicated S. dorsalis had not established a Acetamiprid (Assail) applied to the foliage of pepper plants did not provide significant reduction of S. dorsalis in the present study. Scirtothrips dorsalis Hood. 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. In Japan, Scirtothrips dorsalis is a pest of tea and citrus (Kodomari 1978). Determine distribution of S. dorsalis in different countries in Caribbean Region. Origin and Distribution. 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).

Ghanekar. 2 0 obj << /Length 4445 /Filter /FlateDecode >> stream Scientists believe that Scirtothrips dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. 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 preoviposition period on pepper (3.60 d) was the same as on rose. Mean numbers of larvae per plant were significantly higher on pepper and on the rose cultivar, Knockout, than on bean, eggplant, squash and tomato. In collaboration with f Cooperative Agricultural Pest Survey, we will organize an active surveillance program to detect the pest in south Florida. 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 genus Scirtothrips currently includes 100 listed species from various parts of the world. 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. Immatures, called larvae, look similar to adults but are even smaller and lack wings. Species name. 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. 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. Imidacloprid provided significant reduction of S.dorsalis when applied as Admire as a soil drench or when applied as Provado to the foliage. Scirtothrips dorsalis Hood, 1919. 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. Click to download a PDF version of this publication. Initially yellow sticky cards will be used to trap and monitor S. dorsalis presence and population densities. Develop sampling method for each host crop depending on the distribution of S. dorsalis and identify feeding and reproductive status on those hosts. The number and distribution of setae on the median area of the pronotum are known to be variable within some Scirtothrips species, as well as in some other Thripidae (O'Donnell & Mound 2016). Notes are given on the host range, distribution and recognition of the ten species of Scirtothrips recorded as pests: S. aurantii Faure on citrus in South Africa and bananas in Yemen; S. bispinosus (Bagn.) 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). The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. 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. The risk Scirtothrips dorsalis (Chilli thrips) would pose to California is evaluated below. ���ӧϙO˳�W�0�|:cQ���-�ܜUO�/g�[p�.�d�R�����x��jE�>c� Determine an efficient but accurate method of trapping S. dorsalis. Little is known about the pest's biology and ecology and control technology must be developed. Scientists believe that S. dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. 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 standard trapping method will be developed, which can be used by others in different locations. IMPACT: 2005/09 TO 2008/09 Report progress at the annual meetings of the Florida Entomological Society and the Caribbean Food Crops Society. Attempts will be made to facilitate adoption of this proven control technologies in the management of fruits, ornamental and vegetable production system. Submitted: June 16th 2012 Reviewed: November 13th 2012 Published: March 14th … OUTPUTS: Life table and other parameters of the chilli thrips, Scirtothrips dorsalis were studied in a greenhouse at Homestead, Florida. The pest's flight activity during the windiest hours of the day facilitates it dispersal by wind.
