“…The species composition of the two locations matches the typical carabid fauna of agroecosystems: the range is dominated by Harpalus species, while members of less frequent genera (Ophonus, Brachinus) prefer dry habitats (Saska and Honek, 2004;Kocourek, 2013).…”

Abstract:The benefits of mulching in potato (Solanum tuberosum L.) production are manifold, such as it provides shelters for natural enemies of pests. The aim of our study was to detect the effect of two organic mulch types on the abundance, diversity and species composition of carabid beetles. Our potato plots were located in two sites with similar habitats including similar soil characteristics. Each plot was treated with hay and leaf litter mulch (hay, leaf, control) with 4 replications at each site. It resulted in 24 samples in each study site annually. Carabid beetles were collected by using pitfall traps in between 2011-2013. We found that due to mulching a larger and more diverse carabid population occurred on potato plots. Both mulching types increased the total number of carabids captured having a 17% higher abundance on hay mulched plots and 14% higher abundance on leaf litter mulched plots. According to the results 28 % of the collected species was found only on mulched plots, whereas only 13 % of the captured species were found only on unmulched areas. For some of the species, especially for Brachinus crepitans (L.), the number of individuals was significantly higher on mulched plots. The two different mulching materials had very similar effects on assemblages of carabid species. The species composition of ground beetles was considerably affected by the two locations, and to a lesser extent by the different time periods. While the dominant species of Budaörs was B. crepitans, the most abbundant carabid beetle at Hidegkút belonged to genus Harpalus. Neither hay nor leaf litter were able to constantly increase the biodiversity of the carabid assemblages on potato plots, because the effect of the two years overwrote the between-treatment effects on carabid diversity. The positive effect of organic mulching on carabid diversity however, was found significant in both years of 2011 and 2012.

“…This species attains sufficient abundance that it is suited to be a focus of future monitoring because the number of sites required is realistic. Because it is also abundant in maize elsewhere in Europe (Smith et al ., ; Kocourek et al ., ), it could prove useful as an indicator across the EU (Büchs, ). Although P. rufipes is omnivorous, it is a good indicator of carabid biodiversity (Döring & Kromp, ) and is economically important, preying on invertebrates (Jörgensen & Toft, 1997) and weed seeds (Shearin et al ., ; Harrison & Gallandt, ).…”

“…Exposure to Bt toxins is greatest for species feeding on GM maize but carabids may also be exposed by accidental ingestion of pollen (Stanley‐Horn et al ., ; Lepping, ), exposure to root exudates (Icoz & Stotzky, ), consumption of contaminated prey (Obrist et al ., ) or lower numbers and quality of prey (Meissle et al ., ; Naranjo, ). So far, however, for Lepidoptera‐resistant maize no detectable effects on carabids have been reported in field studies (De La Poza et al ., ; Lopez et al ., ; Kocourek et al ., ; Comas et al ., ), although Meissle et al . () detected adverse effects on carabids fed with larvae that had ingested Bt toxins.…”

1 Post market monitoring of GM crops is mandatory in EU states where they are grown commercially. Carabid beetles are very sensitive to environmental changes and may be used as indicators to monitor impacts of transgenic crops. This study aimed to assess which, where and when carabids should be sampled for improved postmarket monitoring. 2 Carabids were pitfall-trapped in maize fields, field margins, alfalfa and semi-natural vegetation across three regions of NE Spain, during 2 years, and three sampling dates. 3 Overall, 9193 carabids of 42 species were identified, aggregated into trophic groups and used for calculating community measures. The best indicator was Pseudoophonus rufipes (De Geer), satisfying criteria of abundance, relevance, sensitivity, ease of sampling, and sufficient statistical power. The carnivore group should also be monitored as an indicator of biodiversity and invertebrate biological control. 4 The best sampling location was the field margin where carabids are exposed to GM maize and are abundant enough to require smaller sample sizes to detect population changes. 5 Finally, sampling should concentrate around maize pollen-shed when carabid abundance is highest. 6 This study provides baseline data and shows that carabids can cost effectively improve detection capacity of postmarket monitoring.

“…The damage was observed mostly in Zakarpattia Oblast, Polesia, and the forest-steppe, and only in irrigated lands in the steppe (Bolgarin, 2010). Damages grain (wheat, rye, barley, panic grass, oats, corn), grain legumes (pea, wild bean), technical (beet, mustard, flax, cannabis), garden (carrots, onions, cucumbers, lettuce), medicinal (wallflower, poppy, plantain, valerian) and forage (vica, lupin (Lupinus), lucerne) crops, and other plants such as strawberry, hornbeam, and maple (Kocourek, 2013). Feeds on 10 species of wild-growing herbs (Poaceae, Chenopodioidae, Umbelliferae, Compositae).…”

The monograph is presented in four parts. The first part is devoted to the experimental and theoretical substantiation of the criteria for safety and quality assessment of goat's milk. Parameters of subclinical mastitis in goats, comparison of methods efficiency for determination of somatic cell count in goat milk, monitoring studies of goat's and cow's milk in France and Ukraine, effect of exogenous and endogenous factors on the quality and safety of goat milk are described. The second and third parts are devoted to Coleoptera pests of stored food supplies and field crops. The forth part includes characteristics of Poaceae family members in the steppe zone of Ukraine as the main objects of farm animals feeding. Ecological characteristics of the species according to the Belgard Ekomorph System and their geographical analysis were presented. Sozological and feeding value of the species were described.
