  • An Overview of Chilli Thrips, Scirtothrips Dorsalis (Thysanoptera: Thripidae) Biology, Distribution and Management
    Chapter 3 An Overview of Chilli Thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae) Biology, Distribution and Management Vivek Kumar, Garima Kakkar, Cindy L. McKenzie, Dakshina R. Seal and Lance S. Osborne Additional information is available at the end of the chapter http://dx.doi.org/10.5772/55045 1. Introduction The industrial revolution, globalization and international trade liberalization are some of the important events that have afforded vast opportunities for invasive insect species to establish in new territories [1]. These invasive species, facing no challenge by their natural enemies, thrive well in the new environment [2]. In addition to the disturbance they cause to the biodiversity, pest invasion in any country results in increased pressure on biosecurity, national economy, and human health management systems [1, 3, 4]. Apart from economic loss in managing them, these pests pose a significant detrimental impact on tourism and recreational value of the region, which further adds in indirect economic damage to the nation [5]. Of this large group of invasive pests, thrips are one of the most important members. The invasive status gained by thrips across the globe is due to their high degree of polyphagy, wide host range and easy dispersal that can be anthropogenic or natural (wind-mediated). The earliest fossil record of order Thysanoptera dates back to the Late Triassic period, from the state of Virginia in the United States and the country Kazakhstan in Central Asia, but their abundance was rare until the Cretaceous period from which many specimens of Thysanoptera have been recorded [6]. The order Thysanoptera was given its current taxonomic rank by an Irish entomologist, A.

  • Western Flower Thrips (Frankliniella Occidentalis) Management on Ornamental Crops Grown in Greenhouses: Have We Reached an Impasse?
    ® Pest Technology ©2009 Global Science Books Western Flower Thrips (Frankliniella occidentalis) Management on Ornamental Crops Grown in Greenhouses: Have We Reached an Impasse? Raymond A. Cloyd* Kansas State University, Department of Entomology, Manhattan, KS 66506-4004 USA Correspondence : * [email protected] ABSTRACT Western flower thrips, Franklinella occidentalis (Pergande) is considered the most destructive insect pest of greenhouse-grown crops due to direct feeding damage to plant parts such as foliage and flowers, and indirect damage by vectoring the tospoviruses; impatiens necrotic spot and tomato spotted wilt virus. Furthermore, western flower thrips (WFT) is difficult to manage in greenhouse production systems due to a number of factors including broad range of ornamental plants fed upon, high female reproductive capacity, rapid life cycle (egg to adult), residence in cryptic habitats such as unopened terminal buds that protect them from exposure to contact insecticides, and resistance to various insecticide chemical classes. As such, the management of WFT involves a holistic or complex approach including the concurrent implementation of scouting, cultural, physical, insecticidal, and biological strategies. Due to the lack of new insecticides being introduced for control of WFT, it is important that greenhouse producers preserve the longevity of currently existing products by establishing rotation schemes based on different modes of action. In addition, greenhouse producers must utilize sanitation and biological control practices to avoid solely relying on insecticides. The advent of resistance among WFT populations worldwide has led to a general interest among greenhouse producers in adopting the use of biological control as a long-term strategy to deal with WFT, and still produce and sell a quality crop.

    ENY-883 Western Flower Thrips (Frankliniella occidentalis [Pergande])1 Jeffrey D. Cluever, Hugh A. Smith, Joseph E. Funderburk, and Galen Frantz2 Introduction Taxonomy Many species of thrips can be found in Florida. These The order Thysanoptera consists of more than 5,000 species include adventive species like Frankliniella occidentalis, in two suborders, Tubulifera and Terebrantia. The suborder Frankliniella schultzei, Thrips palmi, and Scirtothrips Tubulifera has over 3,000 species in one family, Phlaeo- dorsalis. Native species include Frankliniella tritici and thripidae. The suborder Terebrantia consists of over 2,000 Frankliniella bispinosa. Frankliniella occidentalis is a pest species in seven families. Thripidae is the largest of these of several crops throughout Florida and the world and is families, with about 1,700 species. It includes genera such capable of causing economic loss (Fig. 1). as Scirtothrips, Thrips, and Frankliniella (Mound and Teulon 1995; Mound et al. 2009). Synonyms The original name for Frankliniella occidentalis was Euthrips occidentalis Pergande 1895 (Hoddle et al. 2012; GBIF 2014). This species has a high number of synonymies as a result of the variability that Frankliniella occidentalis has in structure and color in its native range. Some other synonyms are (CABI 2014): Euthrips helianthi Moulton 1911 Euthrips tritici var. californicus Moulton 1911 Figure 1. Western flower thrips adult.

To determine which other viruses are associated with soybean thrips, the metatranscriptome of soybean thrips, collected by the Midwest Suction Trap Network during 2018, was analyzed. Contigs assembled from the data revealed a remarkable diversity of virus-like sequences. Of the 181 virus-like sequences identified, 155 were novel and associated primarily with taxa of arthropod-infecting viruses, but sequences similar to plant and fungus-infecting viruses were also identified.

ULLMAN Department of Entomology, University of California-Davis, Davis, CA 95616 Environ. Entomol. 38(4): 1069Ð1077 (2009) Downloaded from https://academic.oup.com/ee/article/38/4/1069/493304 by guest on 27 September 2021 ABSTRACT Bacterial populations in Frankliniella occidentalis (Pergande) (Thysanoptera: Thripi- dae) collected in diverse California environments consisted of two bacterial symbionts: BFo-1 and BFo-2 (B ϭ bacteria, Fo ϭ Frankliniella occidentalis, numbers reßect different types). Dual infections of BFo-1 and BFo-2 were found in 50% of the thrips, 18% had neither bacterium, and 24 and 8% were infected solely with BFo-1 and BFo-2, respectively. No other bacteria consistently infected F. occi- dentalis. Dual infections occurred more often in male thrips and in thrips of both sexes from southern mountain and valley sites. As average collection year or month minimum temperature decreased, infections of BFo-1, alone or in dual infections, increased signiÞcantly. As yearly precipitation increased, infection with BFo-1 alone also increased. F. occidentalis color morphology did not affect bacterial infection. BFo-1 created weak bioÞlms at 25 and 32ЊC; BFo-2 made strong bioÞlms at 25ЊC and no bioÞlms at 32ЊC. When the bacteria were grown in culture together, weak bioÞlms formed at both temperatures studied, although there was no way to determine what each bacterium contributed to the bioÞlm. BFo-1 and BFo-2 grew at similar rates at 25 and 30ЊC. Our data show BFo-1 and BFo-2 occur in natural populations of F.

Infestation by onion thrips, Thrips tabaci Lindeman, was determined on transplants of onion (Allium cepa L.) received in Colorado during March and April from out-of-state sources (Imperial Valley, CA; near Phoenix, AZ; and southern Texas) during 2004 to 2008. In the 5 years of the study, 50 to 100% of the transplant lots sampled arrived infested with thrips. Among infested transplant lots, the overall number of thrips averaged 0.15 to 0.63 per plant, with as many as four per plant in some lots. T. tabaci was the dominant thrips species in all seasons and locations of transplant origin. In addition, 19 of 83 (23%) tested lots had plants positive for Iris yellow spot virus. Iris yellow spot virus and T.
