Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:

Garrett, Karen A.

Abstract:

Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

Transmission efficiency and life table parameters of western flower thrips, Frankliniella occidentalis (Pergande) exposed to tomato spotted wilt virus-impatiens serotype

Creator:

Sether, Diane M.

Abstract:

Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint, initially observed in a research greenhouse (Corvallis, OR), included stunting and downward curling of leaves accompanied by bronzing, and occasionally tip necrosis. Young leaves appeared either symptomless, deformed, or...

Ambulatory and aerial dispersal among specialist and generalist phytoseiid mites

Creator:

Jung, Chuleui

Abstract:

Specialist and generalist phytoseiid mites are widely used for biological control of spider mites. Understanding dispersal attributes of these mites is important to implementing more stable, cost-efficient integrated pest management. In this regard, we studied dispersal of phytoseiid mites from a local ambulatory phase of movement within a prey patch...
