The article presents the results of studies on the distribution of two types of false shields (Ceroplastes destructor Newstead, 1917; Ceroplastes japonicus Green, 1921) in the Lenkoran-Astara region of Azerbaijan conducted during 2017-2019. The timing of the development of individual stages of the pest, the number of generations, trophic connections and the degree of infection of plants by them are established. Wintering stages have been established. It was noted that C. destructor affects 6 species, and C. japonicus affects 8 species of citrus and subtropical plants belonging to 5 families. It has been established that C. destructor in the south of Azerbaijan can develop in the open ground in 1 generation, and in closed ground in I, II or II ? generations. In 2019, the highest degree of infection with both types of pests was observed.

The mound of Kilindir (fig. 1) lies about one kilometre south-west of the station of that name on the railway that runs from Salonika to Constantinople via Seres, Dedeagatch and Adrianople. A small stream called Gyol Ayak issues from the south side of Lake Doiran exactly at the modern village at Doiran station. This stream, after passing through nine kilometres of broken and ravined country, issues into more open ground just by the modern Chiflik which represents the pre-war site of the village of Kilindir.

В статье представлена информация о происхождении и распространении южноамериканской томатной моли Tuta absoluta Meyrick в мире. По состоянию на конец 2019 года, южноамериканская томатная моль распространена в большинстве стран Южной Америки, в Центральной Америке вредитель отмечен в КостаРике, Панаме и Гаити. В Африке вредитель отмечен в 25 странах. В Азии южноамериканская томатная моль отмечена в Ираке, Иране, Сирии, Турции, Узбекистане, Киргизии, Таджикистане, Азербайджане, Индии, Бангладеш и Непале. Проникнув впервые в Испанию в 2006 году, T. absoluta к настоящему времени широко распространилась в Европе. В России южноамериканская томатная моль была впервые выявлена в 2010 году в республике Адыгея. Дано описание морфологических и биологических особенностей вредителя. Показано распространение и вредоносность томатной моли в Ростовской области РФ. В 2019 году томатная моль распространилась по всей территории станицы Кривянская. Первые признаки повреждения томатов молью в 2019 году отмечали уже с июня, лишь на некоторых отдаленных фермерских участках с июля. Первые очаги в теплицах отмечаются, как правило, на боковых рядах и в углах теплиц. Предложены меры борьбы с вредителем для сдерживания его распространения. Необходим тщательный карантинный контроль продукции и рассады пасленовых культур из зон распространения вредителя, обеспечение пространственной изоляции теплиц от посадок пасленовых культур открытого грунта. Необходимо регулярно уничтожать поврежденные части растений (листьев с минами, плодов с ходами), послеуборочных остатков и пасленовых сорняков. Следует соблюдать плодосмен с выращиванием неповреждаемых промежуточных культур. В течение вегетации необходимо выявлять вредителя и проводить массовый вылов самцов с использованием феромонных ловушек. Международный комитет по предотвращению развития резистентности к инсектицидам рекомендует к применению против T. absoluta порядка 40 препаратов из 12 классов, включая бактериальные.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), postharvest 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.

Relevance. To meet the needs of the population and commodity producers in the south of Russia in tomatoes, it is necessary to develop varieties and hybrids of various directions that have high productivity, increased fruit quality and resistance to fungal and bacterial diseases, that meet modern production technologies and market requirements, as well as have an acceptable price for seeds.Aim of study – creation of new maternal tomato lines with functional male sterility for open ground for various purposes (for fresh consumption, whole-fruit canning,), which will make it possible to create highly productive hybrids that meet the agro-climatic conditions of the south of Russia in the future.Materials and methods. The studies were carried out in a breeding film greenhouse and in field conditions on the territory of the experimental plot of FSBSI "Federal Scientific Rice Centre" of the central soil-climatic zone of Krasnodar region. The object of research were mid-ripening tomato varieties included in the competitive testing, sterile tomato lines, new F1 hybrids based on FMS, collection and breeding material. The types of crosses used in the work: analyzing, saturating, top-crosses. To speed up the process of developing new sterile tomato lines in winter, artificial climate chambers were used.Results. As a result of the research, promising new functionally sterile lines of tomato were identified, differing in the length of the vegetation period, weight, color, fruit shape, biochemical parameters, with a number of useful economically valuable traits.

Saving energy in buildings has become a more important issue in various countries. One strategy that can reduce the cooling load in buildings is landscaping and environmental design. However, it is difficult to estimate the amount of influence of landscape, environment and their elements on ambient temperature. Therefore, the purpose of this study is to examine the relationship between landscape elements and outdoor temperature. The arrangement in relation to temperature reduction is also determined. From the study, it was found that the first important factors that helped to reduce the ambient temperature were water elements, followed by mature trees and ground cover areas. In addition, the outdoor area should be minimally open ground and a hard surface area. The proper placement of each element should be considered specifically the water area should be placed on the south or south-west. The ground cover should be placed next to the building and trees should be placed on the south, east and west sides. The width of canopy of mature trees should be at least 4.5 meters, and evergreen trees should be at least 6 meters of height and dense. Besides these, there are many other variables, such as building layout, building shapes and building materials that may have some effects on the ambient temperature, and they will be studied later.
