Dynamics of the number and species composition of aphids were studied on seed potatoes using yellow water traps in the southern part of the Arkhangelsk region in 2018-2019. 12 species of winged aphids (165 insects) were identified in 2018, and 16 species (115 insects) - in 2019. The following types dominated: black bean aphid A. fabae Scop., bird cherry-oat aphid R. padi L., blackcurrant-sowthistle aphid H. lactucae L., glasshouse-potato aphid A. solani Kalt. The share of aphids as direct and indirect vectors of viral diseases was 91 % of the total number in 2018, and 79.1 % in 2019. The pest population of potato plants depended directly on weather conditions of the growing season. The sum of the average daily temperatures during the period of catching aphids was 1273.3 C in 2018, and 983.3 C - in 2019. During the experimental period, 131.6 mm of precipitation fell in 2018, and 280.4 mm - in 2019. Due to the constant presence of aphids on seed potato crops, annual monitoring of pest population and, in case of necessity, protective measures are required.
