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. Thiamethoxam (Actara) was more effective when used as a foliar application than when applied as a soil drench as Platinum. 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. Determine distribution of S. dorsalis in different countries in Caribbean Region. 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). ���ӧϙO˳�W�0�|:cQ���-�ܜUO�/g�[p�.�d�R�����x��jE�>c� Scirtothrips dorsalis Hood..

Climatological potential for Scirtothrips dorsalis (Thysanoptera: Thripidae) establishment in the United States (PDF | 450 KB). Chilli thrips, Scirtothrips dorsalis, are tiny (> 2mm long), cigar-shaped insects. Two manuscripts will be published in refereed journals on the distribution, bionomics and management of S. dorsalis in the Western Hemisphere. 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. IMPACT: 2005/09 TO 2008/09 A number of nicotinoid and spinosyn insecticides that are highly effective in suppressing chilli thrips populations have been identified. 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). 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. Biological parameters of Scirtothrips dorsalis (Thysanoptera: Thripidae) on selected hosts. Scirtothrips dorsalis was first detected in Highlands County, Florida, in 1991. Bailey (1945) and Priesner (1932), in their work on Scirtothrips, mention S. dorsalis as a distinct species. The spinosyns, spinosad (SpinTor) and spinetoram (Radiant), when applied to the foliage were highly effective against S. dorsalis larvae and adults. Determination host distribution will be informed by previous studies conducted by various researchers in Asia. It has become established on several Caribbean islands and threatens to enter the USA through shipments of peppers, etc. Distribution data. In each country a group of people will be trained to collect and identify S. dorsalis, and prepare specimens for microscopic examination. 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. The sensory abilities of S. dorsalis are poorly understood although the antennae of adult are known to possess important sensory structures in orther insects. 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. Determine distribution of S. dorsalis in different countries in Caribbean Region.

In Japan, Scirtothrips dorsalis is a pest of tea and citrus (Kodomari 1978).

Scientists believe that S. dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. Distribution of chilli thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae), in pepper fields and pepper plants on St. Vincent Transmission of tomato spotted wilt virus, the causal agent of bud necrosis of peanut, by Scirtothrips dorsalis and Frankliniella schultzei. Develop a control method using conventional insecticides labeled for use on fruits, ornamentals and vegetable. Females oviposited most eggs during 10.00 - 04.00 EST. On the otherhand it is not clear why the pest is not yet destructive on tropical fruits in Puerto Rico but not in Florida.
