Ground beetles (Col., Carabidae) are common predators in agrocenoses. A number of plant pests occurring on arable fields become their feed. Therefore, they contribute to a natural reduction of the occurrence of pests. In addition, they are well-known bioindicators used, among others to determine the state of the habitats and the impact of human activity on entomofauna. In the fields, the use of chemical plant protection products is a very controversial activity. The aim of the study was to investigate assemblages of ground beetles occupying conventional and organic sugar beetroot crops. Therefore, to determine the impact of the application of pesticides on the assemblages of these useful beetles was made. The study was conducted at the Agricultural Experimental Station in Winna Góra near Środa Wielkopolska in Poland from May till September of 2004, 2008, 2012 and 2016. The experiment was carried out in the field with organic crop of sugar beet, and in the crop, for which an integrated plant protection programme was planned. The area of each field was 0.5 ha. Modified Barber traps were used to catch insects. On each of the selected fields 10 pitfalls were set up, which were emptied every 14 days. Within 4 years of the study a total of 11865 specimens belonging to 52 ground beetle species were recorded. 5582 specimens belonging to 50 species and 6283 specimens belonging to 46 species were caught in the fields under chemical protection and organic, respectively. On a multiannual scale, there were no statistically significant differences in the number of individuals and species of Carabidae on conventional and organic fields. Fluctuation in ground beetles abundance and species richness were observed dependent on the year of study but not of the treatment. Harpalus rufipes was the most represented species in all fields. The main conclusion is that using chemical plant protection on a multiannual scale does not adversely affect the number and species richness of ground beetles.

The influence of chemical plant protection on carabid beetle assemblages was studied in an experiment conducted on fields of sugar beet at the IOR-PIB Experimental Station in Winna Góra, Poland. The experiment was composed of a block of control fields (no chemical plant protection treatments) and second block, where plant protection was carried out in compliance with the applicable plant protection program. Ground beetles were caught from May to August/September in four years, using modified Barber traps. As a result of the study, 11 881 specimens belonging to 52 species of Carabidae were collected. The most numerous species were: Harpalus rufipes, Pterostichus melanarius, Calathus ambiguus and Bembidion properans. Overall, our results demonstrate that the application of chemical plant protection treatments decreased the abundance of carabid beetles in sugar beet fields, but had no effect on species richness. The use of pesticides induced changes in some life traits of Carabidae fauna. After a pesticide application, the abundance of macropterous hemizoophages and medium carnivores with the autumn type of breeding decreased, whereas the abundance of small carnivores increased.

Neonicotinoids are widely used to protect fields against aphid-borne viral diseases. The recent ban of these chemical compounds in the European Union has strongly impacted rapeseed and sugar beet growing practices. The poor sustainability of other insecticide families and the low efficiency of prophylactic methods to control aphid populations and pathogen introduction strengthen the need to characterize the efficiency of new plant protection products targeting aphids. In this study, the impact of Movento® (Bayer S.A.S., Leverkusen, Germany), a tetrameric acid derivative of spirotetramat, on Myzus persicae and on viral transmission was analyzed under different growing temperatures. The results show (i) the high efficiency of Movento® to protect rapeseed and sugar beet plants against the establishment of aphid colonies, (ii) the impact of temperature on the persistence of the Movento® aphicid properties and (iii) a decrease of approximately 10% of the viral transmission on treated plants. These observations suggest a beneficial effect of Movento® on the sanitary quality of treated crops by directly reducing primary infections and indirectly altering, through aphid mortality, secondary infections on which the spread of disease within field depends. These data constitute important elements for the future development of management strategies to protect crops against aphid-transmitted viruses.

Pests and grapevine diseases in organic production are suppressed by preventive measures with a view to reducing the impact of the attack. Allowed substances acting on patogenous fungi, insects, mites and other harmful organisms are used, if appropriate. Insecticides of plant origin are used in the organic production of grapevine, as well as vegetable oils, powders and insecticidal soaps that are selective, with a narrow range of effects and of lower toxicity, as well as biological products. As a rule, such plant protection products require a more frequent application. Copper-based and sulphur-based fungicides are still leading products in suppressing grapevine diseases. Researches are directed to decrease the quantity of application and to find their replacement by also efficient fungicides. A special emphasis is put on researching the efficient fungicides for suppressing Botrytis bunch rot and factors causing grapevine wood diseases (Esca and Eutypa) in organic production. Along with copper and sulphur, different substances such as bicarbonates, plant extracts and oils, biological products being parasites, patogenous or diseases agent antagonists, and natural products such as milk and whey are applied in the organic production of grapevine.

A correctly selected positioning system for controlling the mobile robotic means movement ensures high positioning accuracy of the robotic platform in the garden, allows to automate precise operations in the garden and systematize route planning algorithms.(Research purpose) To substantiate the rational choice of a positioning system for controlling the mobile robotic device movement.(Materials and methods) The author formulated requirements for the positioning system to perform precise operations in the garden: mechanized collection of fruits and berries, diff erentiated application of fertilizers and chemical plant protection products. The main ones were: the positioning error was no more than 5 centimetres, the stability of information transfer to the server for building traffi c maps, the movement of a robotic device along a given trajectory, equipping beacons with a mobile power source with a capacity of at least 800 milliampere-hour, information exchange between the beacon and the built-in robotic means with a microprocessor controller according to the RS-485 standard, the signal coverage area was at least 100 square meter.(Results and discussion) The six most relevant positioning systems of the following manufacturers were described: RealTrac, Rusoft CKT, Neomatic, ISBC, Avtosensor, Marvelmind. The author compared their technical and operational parameters: operating frequencies, range, data transfer interface, location accuracy and cost of ready-made kits. He showed that Marvelmind provided uninterrupted operation at frequencies of 433 and 915 megahertz with a positioning error of no more than 2 centimetres. The tests were carried out on a small robotic vehicle with the following characteristics: maximum transport speed – 30 kilometre per hour, operating weight – 500 kilograms, length 2 metres, width – 1.2 metres, height – 1.6 metres.(Conclusions) The author substantiated the choice of the most suitable and aff ordable Marvelmind positioning system and experimentally confi rmed the positioning accuracy declared by the manufacturer. When driving in a loop-free and looped turn, the positioning accuracy did not exceed 1.5 centimetres, which met the agrotechnical requirements for mechanized collection of fruits and berries, for diff erentiated application of fertilizers and chemical plant protection products

As a result of a study conducted in 2018, 41 species of ground beetles from 23 genera were identified in the Ushachsky District of the Vitebsk Region (Belarusian Lakeland) as a part of ground beetle assemblages of meadow biocenosis with clogging by the invasive Sosnovsky’s hogweed, whereas without clogging with hogweed 38 species from 21 genera were identified. Species Notiophilus biguttatus (Fabricius, 1779), Dyschiriodes globosus (Herbst, 1784), Bembidion quadrimaculatum (Linnaeus, 1761), Pterostichus oblongopunctatus (Fabricius, 1787), P. minor (Gyllenhal, 1827), P. nigrita (Paykull, 1790), Platynus assimilis (Paykull, 1790), P. krynickii (Sperk, 1835), Bradycellus caucasicus (Chaudoir, 1846), Ophonus laticollis (Mannerheim, 1825), Harpalus latus (Linnaeus, 1758), H. progrediens (Schauberger, 1922), Badister bullatus (Schrank, 1798) were recorded only in the biocenosis with clogging with hogweed. The species richness and the value of the biodiversity index of the ground beetle assemblages of the meadow biocenosis with clogging with hogweed were higher than these parameters of the ground beetle assemblages of the meadow biocenosis without hogweed. In the conditions of invasive hogweed thickets stratobionts boreholes dominated in the ground beetle assemblages (relative abundance 28.57 %), the participation of eurytopic (6 species, 20.37 %) and forest species (7 species, 12.01 %) was high, with a decrease in the share of participation meadow species (3 species, 1.37 %). For the biocenosis littered with hogweed, a high proportion of mesophiles (19 species, 52.44 %) was observed, against the background of a low proportion of mesogyrophils (9 species, 37.69 %).

Global strategies, including application of chemical plant protection products, are important in the cultivation of safe corps and preservation of human health. A promising area of preventive medicine, agronomy, agroecology and agroengineering is the optimization of methods of pesticide formulations application. The aim of the work was a hygienic assessment of the most common and latest methods of crops treatment with chemical pesticides. Results. The biological effectiveness of different types of pesticides is achieved by different application rates of the working solution. The most common method of pesticide application is spraying, which ensures the application of pesticides in the drop-liquid state and is characterized by low consumption of active substance per unit area, variable-controlled distribution on the treatment surface, provides good adhesion and retention on facilities, allows the use of combined formulations. One of the most effective ways to minimize the negative impact of chemical plant protection products and achieve economic success is a rational approach to the choice of pesticide application, as it takes into account the hazard class of pesticides, the presence of water protection zones, the sensitivity of target crops, etc. Conclusion. Rational application of pesticides includes minimizing the overall effect of pesticides on human health and the environment and achieving high-targeted biological efficiency. Adherence to the methodology of choosing the type of pesticide application and selection of the type of spray is a key point in optimizing the rational use of chemical plant protection products, which requires a detailed study from the standpoint of both efficiency and safety. Control over compliance with the recommendations should be included in sanitary-hygienic and sanitary-ecological monitoring.

We studied the effect of climate variations on the structure of the assemblage of ground beetles (Coleoptera: Carabidae) in a wetland and surrounding watershed forest. We analyzed the changes in the structure of the assemblage of ground beetles provoked by a two-year dry period against the background of studies carried out during the two-year wet period. Aridization influenced the structure of the assemblage of ground beetles more in wetlands than in forests. It was shown that despite the stabilizing effect of the forest on the structure of assemblages of terrestrial arthropods, the two-year dry period had a negative impact on the assemblage of ground beetles in the studied area. The Simpson dominance index of 4.9 during the wet season increased to 7.2 during the drought period. Although the total number of species during the dry period did not significantly decrease in comparison with the wet period—from 30 to 27 species—changes occurred in the trophic structure: during the drought period, the number of predators decreased. It is concluded that the resistance of forest habitats to climate aridization is somewhat exaggerated and, very likely, the structure of the community of arthropods in forests will change significantly.

This article aims to indicate the potential impact of the European Green Deal strategy’s solutions on the production of native protein crops for animal feed and its role in achieving sovereignty in the supply of this raw material in Poland. Self-sufficiency in the supply of plant protein is a concern that has been recognized and widely discussed in the national and European scientific community among practitioners involved in the production of livestock feed and, above all, among politicians of the European Commission, which decides the final shape of the EU Common Agricultural Policy. The strategy adopted by the European Commission, referred to as the European Green Deal, proposes restrictions on the use of plant protection products and mineral fertilizers. This will not take place without having an impact on production and the economic situation in agriculture. The research was conducted based on Statistics Poland data and the results of scientific studies. It was concluded that the implementation of the proposed strategy could be a factor that activates the production of native leguminous plants due to their nitrogen-fixing properties. Consequently, this may contribute to an increase in the production of native plant protein for animal feed, and thus to a greater sovereignty in the supply of this raw material for feed purposes.
