    Abundance of tomato spotted wilt thrips vectors on alternative plant hosts associated with the tobacco farmscape in Georgia, U.S.A

    McPHERSON R.M.; MOORE J.M.
    Georgia Mountain Research and Education Center, Blairsville, GA, USA
    Certain species of insect pests called thrips (Family: Thripidae) are known to transmit, or vector, tomato spotted wilt (TSW), a serious virus of flue-cured tobacco produced in the USA. The weed species present in the tobacco farmscape were sampled...

    Managing thrips vectors and tomato spotted wilt tospovirus symptom expression in flue-cured tobacco

    McPHERSON R.M.; MOORE J.M.
    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Tomato spotted wilt tospovirus (TSW) is a serious economic problem for tobacco producers in Georgia, USA. This virus is spread, or vectored, by tiny insects called thrips ( Thysanoptera : Thripidae ) as they feed on the crop. Results are presented...

    Impact of early-season thrips exclusion and suppression on the incidence of spotted wilt in flue-cured tobacco

    McPHERSON R.M.; MOORE J.M.; CSINOS A.S.
    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Incidence in flue-cured tobacco protected in early-season with thrips exclusion (cages) or thrips suppression (weekly acephate insecticide applications with or without an imidacloprid tray trench treatment). TSW is a serious economic threat to...

    Thrips pest management tactics for suppressing tomato spotted wilt virus in flue-cured tobacco in Georgia, USA

    McPHERSON R.M.; MOORE J.M.; CONNELLY F.; JACOBS J.
    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    The influence of four foliar insecticide treatments, with and without a preplant tray drench treatment of the plant activator acibenzolar-S-methyl (Actigard), and three tray drench treatments, with and without foliar applications of Actigard, were...

    Suppression of Tomato Spotted Wilt Virus with acibenzolar-S-methyl and imidacloprid in flue-cured tobacco

    CSINOS A.S.; PAPPU H.R.; STEPHENSON M.G.; MCPHERSON R.M.
    University of Georgia, Coastal Plain Experimental Station, Tifton, GA, USA
    Tomato Spotted Wilt Virus (TSWV) has become the major constraint in tobacco production in Georgia. No single control measure has been found effective in minimizing the severity or incidence of the disease. Foliar applications of...

    Impact of thrips management practices on the incidence of spotted wilt on flue-cured tobacco

    MCPHERSON R.M.; JONES D.C.; BERTRAND P.F.; PAPPU H.R.
    University of Georgia, Coastal Plain Experimental Station, Tifton, GA, USA
    Tomato spotted wilt tospovirus (TSWV) has become a major economic problem of tobacco in Georgia, USA. Several species of thrips have been reported as vectors of TSWV. Three of these species are commonly observed on tobacco in Georgia, and include...

    Distribution of thrips on flue-cured tobacco and impact on the incidence of spotted wilt

    McPHERSON R.M.; JONES D.C.; PAPPU H.R.
    University of Georgia, Dept. of Entomology and Plant Pathology, Tifton, GA, USA
    Flue-cured tobacco fields were surveyed from 1989-91 and 1996-97 to determine the seasonal abundance and species composition of thrips in Georgia, USA. A total of 43 species (including 6 new state records) were recovered from tobacco foliage and...

    Influence of dichloropropene, volunteer peanuts, and thrips control practices on the abundance of insect pests and incidence of tomato spotted wilt in flue-cured tobacco

    McPHERSON R.M.; PAPPU H.R.; CSINOS A.S.; BERTRAND P.F.
    Departments of Entomology and Plant Pathology, University of Georgia, Coastal Plain Experiment Station, Tifton, GA, USA
    The influence of dichloropropene (Telone II), volunteer peanuts (Arachis hypogaea L.), and thrips control practices on insect pest populations, tomato spotted wilt virus incidence, and yield of flue-cured tobacco (Nicotiana tabacum L.) were examined...
