The article deals with data on origin and world distribution of the South American tomato moth, Tuta absoluta Meyrick. At the end of 2019, the South American tomato moth is common pest in most of South America, in Central America, it is noted in Costa Rica, Panama and Haiti. In Africa, the pest has been recorded in 25 countries. In Asia, the South American tomato moth has been recorded in Iraq, Iran, Syria, Turkey, Uzbekistan, Kyrgyzstan, Tajikistan, Azerbaijan, India, Bangladesh and Nepal. Having first penetrated Spain in 2006, T. absoluta has now spread widely in Europe. In Russia, the South American tomato moth was first identified in 2010 in the Republic of Adygea. The description of morphological and biological features of the pest is given. The distribution and harmfulness of tomato moth under conditions of the Rostov Oblast of Russia is shown. In 2019, the tomato moth spread throughout the Krivyanskaya village. The first signs of damage to tomatoes by moths in 2019 have been noted since June, only in some remote farm areas – since July. The first foci in greenhouses are noted, as a rule, on the side rows and in the corners of greenhouses. The pest control measures to limit its further spreading are suggested. A thorough quarantine control of products and seedlings of nightshade crops from the pest distribution zones is necessary, ensuring the spatial isolation of greenhouses from planting nightshade crops in the open ground. It is necessary to destroy damaged parts of plants (leaves with mines, fruits with moves), post-harvest residues and nightshade weeds regularly. It is necessary crop rotation with the growing of intact intermediate crops. During the growing season, it is necessary to identify the pest and conduct a mass catch of males using pheromone traps. The international Committee for the prevention of insecticide resistance recommends the use of about 40 preparations from 12 classes, including bacterial, against T. absoluta.
