A research aim are an exposure and analysis of terms that influence on adjusting of quantity of prattle moth on east of Ukraine, where the quantity of him grows the last years. For the achievement of this aim it was necessary to decide such tasks:: to study de-scription of climatic features of territory of расселения of prattle moth; to give environmentalist biological description of terms of development of wrecker; determination factors that influence on a quantity and distribution of wrecker. Meadow butterfly is one of the most dangerous pests of vegetables, tilled crops, perennial grasses and pastures. His strength is changing dramatically as in some years and for some generations. Depending on the area of climate and weather conditions this year meadow moth has from 1 to 4 different generations and uneven pace of development in various fields.This paper describes the study of the influence of agro meteorological conditions on the development of meadow butterfly populations in Eastern regions of Ukraine.
Introduction. The overview is composed on the base of materials that was received as result of regular stationary hydrometeorological and expedition oceanographic observations at sea coastal zone executed in 2013 and 2014.
Purpose. Hydrometeorological situation in the sea coastal zone has tendency for significant changes due to the climate processes. The aim of this work is to estimate the changes at the last two years. Methods. In the article used results of observations of hydrometeorological characteristics received by standard methods during observations at the sea coastal zone.
Results. At 2013 span of sea level variability was 80 cm. Year average sea level was 487 cm, that isn’t differ from average value for 2003 – 2012 (486 cm). Year average sea level at 2014 was 484 cm. Range of daily average value variation was 67 cm. Water warming-up at May-June also water cooling at September-October was occurred more intensive at 2013 than 2014. Average values of water temperature at 2013 and the average value for 2003-2012 was almost equally – accordingly 12,4ºC and 12,5ºC.At summer season of 2014 water warming-up in the sea coastal zone was so intensive, that average water temperature exceeded similar value at 2013 for 4,5ºC and average long-term value for 2,5ºC.Frequency of storm waving at 2014 was the most for the last 15 years. If year average storm waving frequency at 2003 – 2012 was10 %, at 2013 it was 9,6 %, at 2014 it was 15,8 %.
Conclusion. Climatic conditions and characteristics of the main elements of hydrometeorological regime in the sea coastal zone at 2013 for some exeptions was close to the medium level for the last ten years. At 2014 was the deep warming-up of water, increasing of wind activity, large amount of rainfall loss for the short term that caused significant floods.
Based on results of modelling of autotrophs responses to seasonal temperature variations, the role of temperature in formation of a scenario of cyclic successions of planktonic communities of the Barents Sea and the Black Sea is discussed. The quantity of bioproduction potential realization (μ/μm), taken as a conditional function, is used for the analysis. Discussed are causes of formation and effects of existence of the clear water phase in the Bogorov-Shirshov bimodal scenario of plankton development.
Generalizations of the real hydrometeorological and morphometric information is conducted for the aquatorium of the Kakhovka reservoir, comparison and analysis of results.
Influence of various terms of sowing on growth and development of the leave area, as on one of the main parameters of beans weight formation is considered.
The methodical approaches of determination of evaporation index from charge pool’s water surface were generalized and improved based on real hydrometeorological information of 55 years’ period of observation.
The influence of different agrometeorological conditions on the intensity of pea photosynthesis is considered here.
Influence of environment factors on processes of photosynthesis, breath, growth of winter wheat is modeled. Growth of the main thing and lateral shoots is considered.
The results of many years’ experimental supervisions of the hydrometeorological mode of the irrigated fields of vegetable cultures are analyzed. Influencing of irrigation on a temperature condition and mode of consumption of moisture is appraised by the plants.
Agrometeorological conditions of potato crop formation in Lvov were studied, the main reasons of its crop reduction were set. The potato crop statistical dependenсеt on various agrometeorological indices were devloped wha enable опе to make supposed crop yield prognosis with the to lead time of 1 – 1,5 months.
The estimation of agroclimatic conditions of formation of levels of productivity of agricultural crops and model of definition of optimum structure of areas under crops of a farm is considered.
Estimation of the sun radiation e influence on the increasing of phitomass regrettable cultures is given. It is set, that influence of sun radiation essentially relied on the terms of the water supply sowing, density, terms and norms of irrigation and terms and norms of bringing of the fertilizers.
