Results of monitoring winged aphids (Hemiptera: Aphididae) on potato plantations in the conditions of the Northern region of Russia

The studies were carried out in the conditions of northern part Arkhangelsk region period 2017-2021. purpose research is to determine abundance and species composition during annual monitoring flight winged aphids on potato plantations, establish patterns insect migration. To catch individuals, yellow water traps used, installed along perimeter field at beginning germination phase. last extraction was after desiccation tops. As a result monitoring, 22 identified. Of total number, direct potential vectors viruses are represented by 6 ‒ Acyrthosiphum pisum Harr., Aphis fabae Scop., nasturtii Kalt., Aulacorthum solani Hyperomyzus lactucae L., Rhopalosiphum padi their share structure ranged from 69.8 91.7 %. From group aphids-carriers viruses, 5 annually migrate plantings: A. corni F., R. L. number 61 individuals 2020 107 2018, 2021 there an outbreak mass reproduction which increased captured 1778 individuals. In 2017 2020, prevalence virus corresponded low value (16-27 per 1 trap), 2021, against background reproduction, average (445 trap growing season). accumulation large migratory occurs under favorable weather winter spring periods, also, if possible, feed primary food plant for long time. If host unsuitable feeding, search food, as decreases.
