Analysis of Hungarian Agricultural Subsidies on the Basis of FADN Database
On the basis of the micro-economic data of the Hungarian FADN system we analysed the role of subsidies in the profitability of farms, we aimed to reveal which types of farming and economic sizes are effected more by subsidies related to efficiency and profitability. The agricultural enterprises' balance of taxes and subsidies counted from the micro-economic data of FADN enterprises was also analysed in the different type of farming categories and economic size classes. Our aim was to find out what types of farms are subsidized and what types are net payers to the central budget. Examining the pre-tax profit we made the conclusion that with the increase of economic size not only the proportion of profitable farms rises, but the profit per size unit increases and the loss decreases. Analysing the effect of production based subsidies and interest subsidies on the pre-tax profit we made the conclusion that the sum of subsidies received from government per size unit is almost equal in all economic size classes.agricultural subsidies, profitability, payments of agricultural enterprises, FADN, Agricultural Finance, Q12,
CHANGES OF WEIGHT AND IN-KERNEL CONTENT VALUES OF MAIZE HYBRIDS (OCCITAN, COLOMBA, DK-471) AS A RESULT OF DAMAGING BY EUROPEAN CORN BORER (OSTRINIA NUBILALIS HBN)
The research was conducted in the year 2001 on two fields sown with three different maize hybrids and was based on randomly chosen sample plots. The first survey was carried out on the field sown with hybrids COLOMBA and OCCITAN (total area 120 ha), the second survey was performed on 50 ha of hybrid DK-471. The assessment was focused primarily on the difference between the cobs developed by healthy and damaged maize plants with regards to their weight and the content of protein, fat and starch in the maize kernel.
The hybrids unambiguously reacted to infestation by the European Corn Borer by cob weight reduction. The decrease of kernel fat content in the case of COLOMBA and that of the starch content in the case of OCCITAN displayed significant dependence on the degree of infestation by the European Corn Borer. The results of the survey verifiably showed that in both cases either metabolism, or incorporation of protein, fat and starch had experienced disorder.
A close link has been ascertained between the growth of larvae population and the kernel-cob rate of the examined hybrids. The distribution and number of larvae significantly affected the weight of maize cobs of hybrid DK-471 and the quantity of the basic nutrient components (raw protein, fat and starch) incorporated in the kernel

FLIGHT OF THE EUROPEAN CORN BORER (OSTRINIA NUBILALIS HBN.) AS FOLLOWED BY LIGHT- AND PHEROMONE TRAPS IN VĂRDA AND BALATONMAGYARĂD 2002
The investigations were made in 2002 in the outskirts of two settlements: BalatonmagyarĂłd (Zala county) and VĂĄrda (Somogy county). In the corn fields Jermyâs light- and Arco-Pheron MZ pheromone traps were placed in order to follow up the course of flight. From the material collected the corn borer specimens were isolated, then separated by sex. The generation number of the populations appearing on the respective areas, and the characteristics of the flight were determined. The meteorological data of the areas obtained from Keszthely and KaposvĂĄr for the period concerned were compared woth the data of flight. In that way the effect of the different meteorological elements on the flight and on the trend of the female ratio could be established. The results showed the presence of two-generation corn borer populations in both places. In BalatonmagyarĂłd the first- while in VĂĄrda the second generation proved larger. The meteorological elements significally
influenced the possibility of trapping in the case of both sexes. As for the female sex ratio close correlations were found with the minimum (P=100%; r=0.297)-, maximum (P=99.9%; r=0.267)-, average (P=100%; r=0.308) temperature and precipitation (P=98.2%; r=0.187) data. Considerable asynchrony was observed between the data obtained with the two prognostic means that we ascribed to the unreliability of the pheromone trap
Changing of flight phenology and ecotype expansion of the European corn borer (Ostrinia nubilalis Hbn.) in Hungary Part
The studies aimed to acquire the widest possible information on the annual flight in Hungary of the European corn borer (ECB), Ostrinia nubilalis HĂŒbner (Lepidoptera: Pyralidae). The investigations used biomathematical (Part 1) and graphical (Part 2) evaluation to document changes in the individual population number.The study was conducted in Hungary using ECB moth capture records from the Plant Protection Information System black light trap system (1991â2004). We have drawn conclusions on the appearance of annual flights and the tendency of alterations in flight direction by means of light trap results in four different areas in Hungary. We calculated the flight peak quotients, the individual population numbers of the second flight peak, the distinctions of individual numbers of two flight peaks in this part.As previously published, alterations in flight direction of ECB flights began at different times in Hungary. In the current study, a gradual disappearance of the univoltine ecotype and gradual appearance of the bivoltine ecotype ECB in Hungary is confirmed by the data obtained between 1991â2004. Flight peak quotients and data concerning the second flight peak have confirmed change this process, too: the appearance of a second flight peak in Northwestern Hungary from 1995â1996 (FP = 1.27), the more significant appearance of flights in August in Western Hungary (FP = 1.05) and Northeastern Hungary (FP = 1.45), and a three and four times more individual number of the second flight peak in Southeastern Hungary (FP = 3.44). Flight peak quotients, individual population numbers of the second flight peak, the tendency towards a difference in population number of the two peaks, and size of increase of these values demonstrates the southeastern-northwestern presence of the bivoltine ecotype in Hungary
A STUDY ON MELIGETHES SPECIES IN KESZTHELY, 2002
In 2002 we examined when the Meligethes adults emerged from the wintering places and settled in the rape field. We wanted to know how many species within the genus Meligethes, when and in what proportion and rate appeared in oilseed rape as a feed plant. In our investigations we found the following species: Meligethes aeneus (Fabricius, 1775), M. coracinus (Sturm, 1845), M. viridescens (Fabricius, 1787), M. picipes (Sturm, 1845), M. nigrescens (Stephens, 1830), M. maurus (Sturm, 1845), M. atratus (Olivier, 1890), M. denticulatus (Heer, 1841), M. erythropus (Marsham, 1802)
In silico food-drug interaction: A case study of eluxadoline and fatty meal
Food-drug interaction is an infrequently considered aspect in clinical practice. Usually, drugs are taken together with meals and what follows may adversely affect pharmacokinetic and pharmacodynamic properties, and hence, the therapeutic effects. In this study, a computational protocol was proposed to explain the different assimilations of two ”-receptors agonists, eluxadoline and loperamide, with a peculiar pharmacokinetic profile. Compared to loperamide, eluxadoline is absorbed less after the intake of a fatty meal, and the LogP values do not explain this event. Firstly, keeping in mind the different pH in the intestinal tract, the protonation states of both compounds were calculated. Then, all structures were subjected to a conformational search by using MonteCarlo and Molecular Dynamics methods, with solvation terms mimicking the water and weak polar solvent (octanol). Both computational results showed that eluxadoline has less conformational freedom in octanol, unlike loperamide, which exhibits constant behavior in both solvents. Therefore, we hypothesize that fatty meal causes the âclosureâ of the eluxadoline molecule to prevent the exposure of the polar groups and their interaction with water, necessary for the drug absorption. Based on our results, this work could be a reasonable âcase studyâ, useful for future investigation of the drug pharmacokinetic profile
