Submitted: June 16th 2012 Reviewed: November 13th 2012 Published: March 14th â¦ The use of biocontrol agents will be investigated. Scirtothrips dorsalishas been reported from South Africa and the Ivory Coast, and plant quarantiâ¦ 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 population density was highest during March through June with a peak in April and lowest during January and February. 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. A standard trapping method will be developed, which can be used by others in different locations. %PDF-1.3 %�� A number of nicotinoid and spinosyn insecticides that are highly effective in suppressing chilli thrips populations have been identified. Scientists believe that Scirtothrips dorsalis originated either in Southeast Asia or in the Indian subcontinent, but it is now widely distributed. The https:// means all transmitted data is encrypted — in other words, any information or browsing history that you provide is transmitted securely. 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. Mean numbers of pupae were also higher on pepper and Knockout rose than on these other hosts. 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. Scirtothrips dorsalis was first detected in Highlands County, Florida, in 1991. 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. Disseminate information to research, extension and regulatory personnel, and also to growers in Florida and Caribbean countries. Determine an efficient but accurate method of trapping S. dorsalis. The net reproduction rate (Ro) was higher on pepper (11.50) than on rose (9.47). In Japan, S. dorsalis is a pest of tea and citrus (Kodomari 1978). 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. Its biology and management are little known in the agro-ecosystems in western hemisphere. : Scirtothrips dorsalis distribution in pepper fields 313 tubing. 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). Biology and distribution. REFERENCES: Amin, P.W., D.V.R. Within `Scotch Bonnetâ Pepper Plant Distribution Adult S. dorsalis were abundant on pepper and rose and less so on eggplant, and absent on bean, squash and tomato. 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.) A serious pest on castor, S. dorsalis infests shoots, leaves, flowers and young fruits. 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. Family name. Scirtothrips dorsalis is a widespread pest, described as a new species by Hood in 1919 from 34 females collected in India on castor and chillies and subsequently recorded by Ramakrishna Ayyar (1928) and Shumsher Singh (1944). The adults are pale in color with black, feathery wings and dark spots forming incomplete stripes on the top of the abdomen. The risk Scirtothrips dorsalis (Chilli thrips) would pose to California is evaluated below. Report progress at the annual meetings of the Florida Entomological Society and the Caribbean Food Crops Society. Distribution data. Foliar application of dinotefuran (Venom) provided significant reduction of S. dorsalis on pepper. In Japan, Scirtothrips dorsalis is a pest of tea and citrus (Kodomari 1978). Scirtothrips dorsalis Hood. Determination host distribution will be informed by previous studies conducted by various researchers in Asia. This group will also receive preliminary training on chemical control, biological control and disinfestations of commodities to be exported. Distribution of Scirtothrips Dorsalis in the Carribbean Region and the Development of Chemical and Biological Methods to Manage this Pest. Not recorded from New Zealand but considered a high risk potential invader, this species is widespread from Pakistan to Japan and Australia, and also introduced in Israel, the Carribean area, and parts of South America.

Biological parameters of Scirtothrips dorsalis (Thysanoptera: Thripidae) on selected hosts. Data on various studies will be published as peer-reviewed articles. This may provide information on the feeding and reproductive behavior of S. dorsalis on that species of plant. A list of candidate insecticides has been prepared. Adults were most active during 10.00 - 04.00 EST. 2010. Osborne, C. Palmer, C. Regelburgge, L. Schmale and D. Schuble. The preoviposition period on pepper (3.60 d) was the same as on rose.

In addition we were unable to pursue much of the planned research on biological controlof S. dorsalis. Acetamiprid (Assail) applied to the foliage of pepper plants did not provide significant reduction of S. dorsalis in the present study. World distribution of Scirtothrips dorsalis (SCITDO) Continent Country State Status; Africa: Cote d'Ivoire: Present, restricted distribution These objectives will be conducted in close cooperation with CARDI scientists and personnel from Ministry of Agriculture in each country, especially St. Vincent and the Grenadines and St. Lucia, where most of the work on chemical, biorational cultural and biological control will be conducted. Also the use of a number of the less harsh biorational chemicals will be developed. 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. A number of potentially effective predators have already been identified, and their effectiveness in the field will be assessed. Abstract.
