Study of Aphid Population in Seed Potato Crop

Abstract

This paper presents the results of aphid species monitoring in the seed potato crop during the growing season using Moerike aphids trap in 2020 and 2021 at INCDCSZ Brașov. Aphids control as direct pests is rarely justified in potato crop but absolutely necessary to prevent indirect damages caused by infecting potato plants with viruses transmitted by aphids. The aphids monitoring in seed potato crops is absolutely necessary to reduce the risk of the appearance and development of aphid populations, implicitly to decrease the incidence of viral contamination. During the two years of study, winged aphids were collected using yellow water traps¸ The vector aphid species were identified from the total of collected aphids. The identification resulted in a number of 20 vector species (682 - total number of individuals) in 2020 and 24 vector species (1843 - total number of individuals) in 2021.
