Aphids are the most important vectors of potato viruses during the crop’s growing season.\udThe most widespread and damaging viruses, the potato virus Y and potato leaf roll\udvirus, are transmitted by aphids in non-persistent and persistent manner, respectively. The\udtwo viruses cause the greatest concern of potato producers and a great constraint to seed\udpotato production in Serbia, the region and across the world. Potato virus Y is particularly\udharmful, given its distribution and spreading rate.\udSeed potato production systems under well-managed conditions involve a series of\udvirus control measures, including the monitoring of outbreaks of winged aphids, their\udabundance and species composition, in order to forecast virosis, i.e. potential plant and\udtuber infection periods. Monitoring the aphid vectors of potato viruses enables determination\udof optimum dates for haulm destruction when higher than normal numbers of\udwinged aphids as vectors of economically harmful diseases have been observed. Haulm\uddestruction in a potato crop reduces the risk of plant infection and virus translocation from\udthe aboveground parts to tubers, thus keeping the proportion of infected tubers within\udtolerance limits allowed for certain categories of seed potatoes. This practice has positive\udeffects if used in combination with other viral disease control measures; otherwise, it\udbecomes ineffective.\udThis paper provides an integral analysis of the effects and role of monitoring outbreaks\udof aphids, their abundance and species composition in timing haulm growth termination\udto prevent plant infection, virus translocation and tuber infestation in potato crops in Serbia\udand the wider region
