... A field study was conducted in east-central Alabama, USA in 2008 to evaluate the influence of colored plastic mulch on ability of thrips to locate tomatoes (Solanum lycopersicum). Mulch colors (red 1, red 2, and violet) were mulches manufactured (Pliant Corp., Washington, GA, USA) based on ultraviolet reflectance, which has been shown to repel thrips, were compared to standard black and silver mul ...
... The predatory mite Amblyseius swirskii quickly became one of the most successful biocontrol agents in protected cultivation after its introduction into the market in 2005 and is now released in more than 50 countries. There are several key factors contributing to this success: (1) it can control several major pests including the western flower thrips, Frankliniella occidentalis, the whiteflies Bem ...
... In the current study, potential involvement of anthocyanins in the defence of the Zn hyperaccumulator plant, Noccaea caerulescens, was investigated in two independent glasshouse experiments. Plants were grown in compost amended with a range of Zn concentrations. In the first experiment, foliar herbivory was simulated by clipping the shoots with scissors, whilst in second experiment, plants were su ...
... It has been shown that pollen as a dietary supplement may increase the establishment (development and reproduction) and survival of phytoseiid predatory mites, and therefore the pest control these mites can provide. In this study, the role of apple pollen as a supplemental food source was assessed as a means to increase the efficiency of two predatory mite species, Neoseiulus cucumeris and Amblyse ...
... Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) (western flower thrips, WFT) is a key pest in a range of crops worldwide. Anthocorid species (Hemiptera) are important natural enemies of thrips. Several experiments were undertaken to determine whether a thrips lure, methyl isonicotinate (MI), affected the behaviour of WFT and anthocorids found in outdoor crops. Currently, this volat ...
... The entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin and predatory mite Neoseiulus barkeri Hughes are effective biological control agents of Frankliniella occidentalis Pergande (Thysanoptera: Thripidae), one of the most important pests of ornamentals and vegetables world-wide. Combined application of both may enhance control efficiency. The functional response for N. barkeri on the f ...
... BACKGROUND: Iphiseius degenerans (Berlese) (Acari: Phytoseiidae) is a common predatory mite in citrus orchards in some areas of the Mediterranean basin and an important biological control agent of the thrips Frankliniella occidentalis (Pergande) in Integrated Pest Management (IPM) programmes in greenhouse crops. In this study, we evaluated the effects of the ‘reduced‐risk’ insecticides acetamiprid ...
... BACKGROUND: Frankliniella occidentalis is a worldwide economically important pest. Scarcity of effective products and cross‐resistance issues make resistance to existing insecticides a recurring problem that requires the development of new control tools, such as incorporating novel compounds. Lethal effects of cyantraniliprole on adults and larvae from field and insecticide‐resistant populations w ...
... Sublethal doses of some insecticides have been reported to either stimulate or reduce the survival and fecundity of insects. Many sublethal-effect studies have been conducted after exposure of only one generation to sublethal insecticides, and there is little information about the sublethal effects on insects after long-term exposure to sublethal insecticides. In this study, changes in biological ...
... Tomato spotted wilt virus (TSWV) is transmitted by Frankliniella occidentalis (Pergande) in a persistent–propa-gative manner. We previously observed significant results in terms of feeding behavior of spinosad-susceptible (Ivf03) and -resistant (Spin-R) strains of F. occidentalis using electrical penetration graph. TSWV transmission by the two strains was compared in the present study. The results ...
... Natural enemy exploitation of food resources and alternative hosts in noncrop vegetation has been shown to be an effective means of enhancing natural enemy populations in diversified agro-ecosystem. Field trials were conducted in Hawaii to examine effects of interplanting flowering plants on 1) parasitism of corn earworm, Helicoverpa zea (Boddie) eggs by Trichogramma spp., and 2) abundance of Oriu ...
... The Tomato yellow ring virus (TYRV, family Bunyaviridae, genus Tospovirus) was found for the first time in greenhouses of Shiraz in the southern province of Fars, Iran, in 2007. TYRV, like other tospoviruses, is transmitted by thrips. Many factors affect the transmission efficiency of thrips-borne viruses such as thrips species or belonging to different populations. In this study, we evaluated the ...
... A modified residual contact vial bioassay (RCV) in which a small aliquot (1μl) of water was supplemented to minimize control mortality was established as a rapid insecticide resistance monitoring tool for the western flower thrips, Frankliniella occidentalis. Based on the RCV scheme, diagnostic doses for seven insecticides that are widely used for F. occidentalis control were determined at 8h post ...
... Western flower thrips, Frankliniella occidentalis (Pergande) is an important insect pest of greenhouse roses. Trials were carried out in glasshouse grown roses with the commercially available thrips lures ThripLine ams (male sex aggregation pheromone) and Lurem-TR (kairomone) with yellow sticky traps to evaluate their efficacy as part of a monitoring and mass trapping strategy against F. occidenta ...
... Although phytoseiids are best known as predators of phytophagous mites and other small arthropods, several species can also feed and reproduce on pollen. In laboratory assays, we assessed the profitability of two types of dietary supplements (three pollen species—cattail, maize and apple—and eggs of the Mediterranean flour moth, Ephestia kuehniella) for the two species of predatory mites most comm ...
... This study was conducted in the Biskra region (Southern Algeria) during the crop year 2010/2011 and provides the first observation of Thrips tabaci and Frankliniella occidentalis (Thysanoptera, Thripidae) on greenhouse crops in Algeria. Tomato is relatively highly infested compared to chilli and sweet pepper. Population levels of T. tabaci are higher than those of F. occidentalis on the three crop ...

Abstract:
... The aim of this work was to study the life cycle of Cosmolaelaps jaboticabalensis Moreira, Klompen and Moraes preying on Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), a serious cosmopolitan pest of different crops, as well as on Protorhabditis sp. (Nematoda: Rhabditidae) and Tyrophagus putrescentiae (Astigmatina: Acaridae), prospective factitious foods for the mass rearing of th ...
... Western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), widely distributed in the main Chinese cut flower production areas, present a problem because it is listed as a quarantine pest in some exporting countries. Phosphine (PH3), a potential alternative to methyl bromide (MB), was investigated to determine its effects on postharvest control of western flower thrips at low temp ...
... Four different thrips species; marigold thrips, Neohydatothrips samayunkur; western flower thrips, Frankliniella occidentalis; tomato thrips, Frankliniella schultzei and onion thrips, Thrips tabaci were recorded on marigold plants in the field. Tagetes erecta L. was grown in the experimental farm, Giza governorate, Egypt. The survey was carried out during mid-April to late July and from early Sept ...
... BACKGROUND: Hoverflies (Diptera: Syrphidae) are generalist predators of a great variety of pests. Nasonovia ribisnigri (Hemiptera: Aphididae) and Frankliniella occidentalis (Thysanoptera: Thripidae) are two common pests in Mediterranean lettuce crops, where they occur alongside alternative prey (e.g. Collembola). A semi‐field experiment was conducted in an experimental lettuce plot where hoverfly ...
