Modeling temporal trends in aphid vector dispersal and cucumber mosaic virus epidemics in snap bean.
Cucumber mosaic virus (CMV) has become a major limiting factor in snap bean production in the Great Lakes region of North America, and epidemics have occurred more frequently since the soybean aphid, Aphis glycines Matsumura, was introduced. Major aphid vectors of CMV epidemics were identified by statistically relating their temporal dispersal trends to the incidence of CMV. Alates were monitor...
Introduction The whitefly Bemisia tabaci Genn. (Homoptera:Aleyrodidae) has caused millions of dollars worth of crop losses in tropical and subtropical agricultural regions in the five continents of the world (Brown, 1994). Besides the direct damage caused by B. tabaci (plant nutrient loss; physiological disorders; honey dew excretions, etc), the sweet potato or cotton whitefly is an efficient v...
In January 2014, an outbreak of infection with highly pathogenic avian influenza (HPAI) A(H5N8) virus began on a duck farm in South Korea and spread to other poultry farms nearby. During this outbreak, many sick or dead wild birds were found around habitats frequented by migratory birds. To determine the causes of death, we examined 771 wild bird carcasses and identified HPAI A(H5N8) virus in 1...
Worldwidecrop losses due to plant diseases exceed $60 billion annually. Next to fungi, viruses represent the greatest contributor to those losses, and these are transmitted in nature primarily by insects. Mexican bean beetles (Epilachna varivestis) are formidable pests of soybean, as well as efficient vectors of several soybean-infecting viruses, including Bean podmottle virus (BPMV). Beetle-bo...
ABSTRACT Cucurbit leaf curl virus (CuLCV), a whitefly-transmitted geminivirus previously partially characterized from the southwestern United States and northern Mexico, was identified as a distinct bipartite begomovirus species. This virus has near sequence identity with the previously partially characterized Cucurbit leaf crumple virus from California. Experimental and natural host range stud...
Increasing evidence suggests that macrophages (M(phi)s) are necessary for persistence of Theiler's murine encephalomyelitis virus (TMEV) in the mouse central nervous system. Analysis of BeAn virus infection in the Mphi cell lines P388D1, J774A.1 and PU5-1.8, which are intermediate in their state of differentiation and resemble multifunctional resident M(phi)s, revealed restricted TMEV growth. A...
