This paper presents data on the abundance, dynamics and diversity of aphid species collected with yellow pan traps and the suction trap on potato crops. Aphids (greenfly, blackfly, plant louse) are an extremely important group of pests that limit crop productivity by causing severe damage either directly, by feeding on plant sap, or indirectly as vectors of the most important viruses. The main damage to the aphid crop of seed potatoes is due to the spread of phytopathogenic viruses. Production losses due to infections with potato leaf roll virus (PLRV) can vary between 53-81% and for potato virus Y (PVY) between 33-89%, depending on the abundance and structure of aphid populations, potato variety, infection rate, vegetation stage and year-specific climatic conditions. A total of 4102 specimens of 113 different species were collected and identified. The large number of specimens and species collected in 2020 with suction trap (3180 from 108 species) compared to the yellow pan traps (922 from 65 species) is noticeable. [ABSTRACT FROM AUTHOR] |
