Thrips transmission of viruses, fungi and bacteria is reviewed and the specific biological relationships occurring between thrips and pathogens are explained. The main section of this chapter is concerned with thrips transmission of tospoviruses, with reference to tospovirus phylogeny,...

A comparison of efficiency and propensity as measures of vector importance in zucchini yellow mosaic potyvirus (ZYMV) transmission by A. gossypii and A. craccivora was made. Efficiency was measured in the laboratory with single aphids exposed in sequence to an infected plant and then 4 noninfected...

Thirteen Lycopersicon accessions were compared for landing of Frankliniella occidentalis on leaves and flowers and resistance to tomato spotted wilt tospovirus (TSWV) in field experiments on the Hawaiian island of Maui. Occurrence of Thrips tabaci and Trialeurodes vaporariorum on leaves was also...

Zucchini yellow mosaic potyvirus (ZYMV), an isolate of papaya ringspot (type W) potyvirus (PRSV-W), and cucumber mosaic cucumovirus (CMV) were found infecting commercially grown cucurbits on the Hawaiian islands of Oahu, Maui and Molokai, USA, during 1988 and 1989. Although previously reported in...
