The area and zones of harmfulness of the green rose aphid Macrosiphum rosae L. (Hemiptera, Aphididae) on the territory of Russia and the neighboring countries

Abstract

The paper presents an original map of the distribution area and zones of medium and high harmfulness of the green rose aphid Macrosiphum rosae L. on the territory of Russia and the neighboring countries. When creating the map, data from literature sources and proprietary materials on the NorthWest of Russia were used, obtained during the identification of the insects collected from yellow water traps, Malaise traps, suction trap. The data was linked to geographical coordinates based on a Geographic Information System (GIS) created by MapInfo Professional software version 16.0 (Pitney Bowes Software Inc.). The northern boundary of the species' area begins from the Southern border of the Khibiny Mountains, runs along the Central part of the Arkhangelsk region, the southern border of the Komi Republic to the Ural Mountains. The zone of medium harmfulness of the object includes Belarus, most of Ukraine, the Central Chernozem zone of Russia, the North Caucasus, and the Trans-Caucasian region. In the years favorable for the development of the insects, the damage to plants here is 2 points, periodically – 3 points. The zone of high harmfulness includes Moldova, Crimea, the Black Sea coast of the Caucasus, Trans-Caucasian region, and Ukraine. The successful life of aphids in these regions is facilitated by a warm, moderately humid climate, as well as an abundance of forage plants. Roses are damaged in this case by 3 points or higher. In spring, green rose aphids are found in small numbers in Central Asia and Western Kazakhstan. In Western Siberia, there are few individuals of aphid on roses of open and closed ground, as well as on the rosehip. In the Primorsky Territory, the species is found everywhere on various types of rosehips, forming large colonies on young shoots.
