The aim of our study was the synthesis of the active components of the apple worm, Cydia pomonella L. - E8, E10-dodecenol and the grape moth, Lobesia botrana S. - E7, Z9-dodecadienol and their minor components E-8-dodecenol and E-9 -dodecenyl acetate. Different amounts of components were impregnated in each rubber dispenser. Pheromone traps was given to be tested in field monitoring trials to determine the most effective optimal pheromone blend ratio in the geographical and climatic conditions of the Republic of Moldova.

Trap Catches

AbstractPheromone traps were deployed in Borsod-Abaúj-Zemplén County (Hungary) between 1982 and 1988, in 1990 and also between 1993 and 2013. These traps attracted 8 Microlepidoptera species:Phyllonorycter blancardella, P. corylifoliella,Anarsia lineatella,Eupoecilia ambiguella,Lobesia botrana,Grapholita funebrana,G. molestaandCydia pomonella. We examined the trapping data of these species in the context of lunar phases and polarized moonlight. Catches of the European Vine Moth (Lobesia botrana) and the Codling Moth (Cydia pomonella) were higher in the First Quarter, whereas catches of Peach Twig Borer (Anarsia lineatella), Vine Moth (Eupoecilia ambiguella), Plum Fruit Moth (Grapholita funebrana) and Oriental Fruit Moth (Grapholita molesta) were larger in the Last Quarter. Catches of the other two species, the Spotted Tentiform Leafminer (Phyllonorycter blancardella) and Hawthorn Red Midget Moth (P. corylifoliella), were higher in both the First and Last Quarters. When using pheromone traps, insects do not fly to a light source, so moonlight does not modify either the catching distance or flight activity. However, at high levels of polarized moonlight, pheromone trap catches will increase, as in the case of light-trap catches. The results are comprehensible when one considers that the target species can fly both during the daytime and also at night.

Phacelia tanacetifolia Benth., which is a species with high potential as forage and honey plant, served as the subject of a new study. The species is characterized by short growing season, staggered and long flowering period (about 55 days depending on the climatic conditions and the date when it was sown). Under laboratory conditions, the germination capacity of the seeds is 84-92 %. The climatic conditions of the Republic of Moldova allow P. tanacetifolia plants to complete the whole ontogenetic development cycle – they bloom, bear fruit and produce viable seeds.

In the paper presents the allogeneic invasive species Cydalima perspectalis, first registered in the Republic of Moldova in 2017 in a park in the Chisinau capital. In 2018, investigations have been held to confirm its evolution in line with the climatic conditions in the area. According to species development in the second half of 2017 and the first half of 2018, it was found that the species is developing as in other countries in Europe: two generations and with the same aggressiveness. The paper describes the recommended fighting methods in countries where the species has developed in Europe, which are also valid for the republic.

With the aim of studying the influence of genotype and climatic conditions on the content of β-glucans, fat and protein in grain, oat samples were grown in the Krasnoyarsk territory region and the Republic of Khakassia for three years. The object was 1 naked and 2 husked samples of oats of Krasnoyarsk selection. The content of β-glucans and fat was measured on an automatic grain analyzer Infratec Analyzer 1241 using 50 ml cuvette. In parallel, standard methods were used to measure other chemical and physical characteristics of oat grain: protein content in the grain, its filminess, weight of 1000 grains. It was found that the husked samples formed a grain with a content of β-glucan in it about 3% and naked over 4%, while a noticeable advantage of the naked sample compared with the husked in the content of protein and fat in the grain was found. Cultivation of different oat samples in two geographical areas of Eastern Siberia for three years showed insignificant positive impact of climatic conditions of Khakassia on the content of β-glucans in grain, its size and filthiness and negative impact on fat and protein content. Comparison of the content of β-glucans and fat in oat grain of three varieties from two geographical points revealed a significant effect of the genotype (63.6 and 66.6%, respectively) and a slight influence of the point of cultivation, as well as the interaction of the genotype×point. The existence of strong negative links between the weight of 1000 grains and the content of β-glucans, fat or protein in the grain, as well as strong positive reliable links between the content of β-glucans and fat in the grain.

Hyalesthes Obsoletus

Hyalesthes obsoletus (Signoret) is an important vector of Wood Blackening in the Republic of Moldova. To identify the causes of the epidemiology of this disease in vineyards, the period of flight and the preference of the host plant H. obsoletus in the field were studied. Monitoring of vineyards showed that this species was found on the Field Bindweed (Convolvulus arvensis L.), and during the period of mass flight, the leafhopper was observed on Xanthium strumarium and Gorets bindweed (Fallopia convolvulus L.). The captured leafhoppers were diagnosed with the presence of Bois Noir stolbur phytoplasm (STOL). The adults of H. obsoletus were also caught from other herbaceous plants: Povoy fence (Calystegia sepium L.), Garden quinoa (Ariplex hortensis L.), Sow thistle (Sonchus oleraceus L.), Medicinal dandelion (Taraxacum officinale L.), as well as c Stinging nettle (Urtica dioica L.). Changes in climatic conditions in the region, causing premature drying of the grass cover, forces cicadas - vectors to switch to actively growing plants during this period, including grapes, which contributes to the widespread of the disease.

In this paper is reported the evaluation of biological efficacy of two minor components that was added to the basic sex pheromone component Cydia pomonella L., E8, E10-C12-OH. The use of minor component- C.M.-1 of increasing concentrations in binary mixture compositions with the basic sex phe-romone component of codling moth on pheromone-impregnated rubber septa in delta pheromone traps has shown an increased effectiveness by 56-62% in field trials on apple orchard. At the same time, the number of males caught in delta pheromone traps where were used minor component - C.M.-2 in binary mixture compositions increased by 29-35%. Auxiliary research is still needed.

Abstract The viticulture, a traditional branch of the national economy, is closely related to climatic conditions because the Republic of Moldova territory represents the northern border of its territorial location. Therefore the knowledge of regional particularities of grapevine productivity formation in dependence of current agro-climatic conditions is of particular interest. Along with accelerated climate change in last decades over the Republic of Moldova territory, we find that are essential changes concerning agro-meteorological conditions, at the same time comprehensive researches that would reflect the actual impact of climate change on grapevine are limited. There are known researches, but in the context of changes that occur at regional level it is necessary to supplement permanently the database in order to elaborate an appropriate estimation of current climate conditions. The above reported facts show the importance of parameters influencing the grapevine productivity time and space study in Republic of Moldova.

Abstract Aridity in new climatic conditions requires indexes which could adequately explain this process. All the more so, the quantities of atmospheric precipitations also continue to increase on the background of the temperatures increase in the conditions of the Republic of Moldova. Their variable character in the last period of time with the installation of dry and droughty periods alternating with rainy flood-provoking periods determines the selection of the most optimal ecometric indexes that could correctly explain the occurrence of pronounced desertification in the last period of time.
