Occurrence of Thrips tabaci larvae on TSWV host weeds in the surroundings of sweet pepper greenhouses
Acta Phytopathologica et Entomologica Hungarica 43 (2), 329-336
Abstract: The relationship between virus, host plant and vector species is of primary importance for understanding the development of Tomato Spotted Wilt Virus (TSWV) epidemics. One of the vectors, Thrips tabaci , occurs in Hungarian greenhouses and their surroundings all year round. From June 2005 to May 2007 we conducted studies on weed hosts growing in the vicinity of sweet pepper greenhouses in order to know on which TSWV host weeds the larvae develop in different seasons. Of the 16 TSWV host weeds collected Stellaria media proved to be the most frequent weed species with the greatest abundance and it occurred the whole year round at all five investigated locations. Together with Galinsoga parviflora , which had the highest number of T. tabaci larvae in autumn, S. media is very probably the main source of TSWV for epidemics in greenhouses.
