The present paper includes the results of a year-round pitfall trapping survey of ground beetles in the region of Lake Elton, Volgograd Area, Russia. The main objectives of the project lie in studying the local fauna of Carabidae in the Lake Elton region, as well as their demographic structure and dispersal potential of the local populations of particular carabid species. A total of ten model habitats: six zonal (characteristic of that particular biogeographic area) and four azonal (present in a variety of biogeographical areas) were studied. In each model habitat, ten pitfall traps were set from 10 May 2006 until 10 May 2007 and were checked at 10-day intervals except for the period with negative temperatures (from 1 November 2006 until 31 March 2007). During the period of observation, 51,314 specimens of Carabidae, belonging to 149 species, were trapped. The resulting sampling-event dataset includes 24,291 plot-based observations (= sampling events), some of them containing zero records of particular species in a certain habitat and time. This is the first sampling-event dataset of a year-round pitfall trapping survey (from May 2006 until May 2007) of ground-beetle communities and the demographic structure of local populations of particular species in the Lake Elton region, Volgograd Area, Russia.

Pan Traps

Pitfall trapping is a widely used sampling method for biodiversity-related research of ground-dwelling arthropods. The trap is a container, usually with a preservative, that is sunk into the ground to collect arthropods which happen upon the trap perimeter and fall in (Lemieux and Lindgren 1999; Work et al. 2002). Two types receive the most use: deep circular pitfall traps and shallow rectangular pan traps (Marshall et al. 2001). The preserving fluid can influence trap efficacy (Deville and Wheeler 1998). Our objectives were to compare the efficiency of pitfall and pan traps with and without detergent in the preserving fluid (Marshall et al. 1994), using carabid beetles (Coleoptera: Carabidae) and spiders (Araneae) as focal taxa.

The Ground beetles occurrence in agricultural areas can contribute to pest control as well as indicate environmental quality. This study aimed to evaluate the composition of the Carabidae community in an agricultural area of annual crops. Ninety-six pitfall traps were installed in a grid 10 meters apart. The experimental area had one hectare in a double-cropping system of soybean (summer) and corn (autumn-winter) followed by a fallow period. Ground beetle composition analysis was performed using ANAFAU software. We collected 42 species and 1537 specimens of Carabidae distributed in 14 tribes. Harpalini tribe was the most common compared to the others. Were considered predominant, in the fauna analysis, the species Calosoma alternans granulatum Perty, 1830, Selenophorus discopunctatus Dejean, 1829, Selenophorus alternans Dejean, 1829, Selenophorus sp.1, Tetracha brasiliensis (Kirby, 1819), Abaris basistriata Chaudoir, 1873 and Galerita collaris Dejean, 1826. Thus, a diverse and abundant Carabidae community was identified in that cropping system.

AbstractPterostichus melanarius Ill. was the predominant ground beetle recovered in pitfall traps in three blocks of apple trees at Jordan Station, Ont. In one block, C, the number of mature fifth-instar larvae of Cydia pomonella (L.) seeking overwintering sites was related significantly (r2 = 0.5476, P < 0.05) to the number of P. melanarius caught, but was not related significantly (r2 = 0.1181, P > 0.10) to the proportion of beetles that were serologically positive. The proportion of larvae pupating also was not related significantly (r2 = 0.2014, P > 0.10) to the number of P. melanarius. The total number of all predators caught was related significantly (r2 = 0.4490, P < 0.05) to the number of larvae present, but the proportion of larvae that pupated was not related significantly (r2 = 0.3606, P > 0.05) to the total number of predators.In block A, in 1983–1985, the number of mature larvae of C. pomonella seeking overwintering sites was not related significantly (r2 = 0.3763, 0.3619, and 0.5042, P > 0.05, respectively) to the number of P. melanarius taken in pitfall traps. In both blocks A and B, the number of serologically positive beetles was not related significantly (r2 = 0.3824 and 0.7921, P > 0.10, respectively) to the number of larvae seeking overwintering sites.Amara aenea DeG., Anisodactylus sanctaecrucis F., Bembidion quadrimaculatum oppositum Say, Clivinia impressifrons LeC., Diplochaeila impressicolis (Dej.), Harpalus aeneus F., and Pterostichus chalcites Say also gave positive serological reactions to the antiserum against C. pomonella.The occurrence of other species of Lepidoptera did not affect significantly the results obtained for C. pomonella.

The series of epigeibiontic Arthropoda communities are investigated in several fo­rest and woodland ecosystems of Lva-Stvyga inter-river area within Volyn Polissia region of Ukraine. This is remoted district with peculiar ecological features as well as dominancy of oligotrophic forest and peat-bog ecosystems. The material of epigeibiontic arthropods was collected in spring and summer 2015 by the method of Barber’s pitfall traps. There are three pilot areas explored: 1) wet oligotrophic pine woodland (Ledo-Pinion); 2) late secondary succession of wet oligotrophic pine woodland cutting area; 3) dry oligotrophic pine woodland on the sands (Dicrano-Pinion). In total, 186 species of epigeibiontic arthropods were explored. There were found 75 species of spiders (Araneae) and 27 species of ground beetles (Coleoptera, Carabidae) among them. Along with that, the ants (Formicidae) have dominancy within related communities with an amount about 82–87 % of total arthropod individual’s number, and Araneae both with Carabidae exceed 6–7 % of this number. Nevertheless, there are nine spider species found for the first time for Ukrainian Polissia region and 1 species – Gnaphosa nigerrima – for the territory of Ukraine. One Carabid beetle species (Cymindis vaporariorum) was found at the first time for West Polissia region of Ukraine. There is also a number of rare and less known Araneae and Carabidae species found. Thus, the species composition and structure of explored Araneae & Carabidae communities show many specific features, which are caused by characteristic ecological and biogeographical peculiarities of oligotrophic ecosystems within investigated area. Following research of related taxonomical groups has to be directed to the wider spectrum of ecosystems covering, especially to peat-bog and mire complexes as unique protected habitats in Ukraine and the European Union.

This study aimed at clarifying the species composition and ecological structure of carabid communities, in oilseed rape fields after rape harvest. Field work was carried out in 2018. Pitfall traps (5 in each site) were set in 10 sampling sites in Thracean Lowland and Sarnena Sredna Gora Mts. Captured beetles belonged to 66 species and 24 genera, representing 9% of the species and 19% of the ground beetle genera occurring in Bulgaria. The most diverse was genus Harpalus Latreille, 1802 (15 species), followed by the genera Amara Zimmermann, 1832 (7 species), Microlestes Schmidt-Goebel, 1846 (6 species) and Parophonus Ganglbauer, 1891 (5 species). Five species were new for the region of the Thracean Lowland: Amara (Bradytus) consularis (Duftschmid, 1812), Harpalus (Harpalus) caspius (Steven, 1806), H. (Pseudoophonus) calceatus (Duftschmid, 1812), Microlestes negrita negrita (Wollaston, 1854), Tachyura (Tachyura) parvula (Dejean, 1831). Three species: Amara (Zezea) fulvipes (Audinet-Serville, 1821), A. (Zezea) chaudoiri incognita Fassati, 1946 and Diachromus germanus (Linnaeus, 1758) were new records for the region of the Sarnena Gora. Seven species were new for the whole Sredna Gora Mts.: Acinopus (Acinopus) picipes (Olivier, 1795), A. (Oedematicus) megacephalus (P. Rossi, 1794), Carterus (Carterus) dama (P. Rossi, 1792), Harpalus (Harpalus) flavicornis flavicornis Dejean, 1829, H. (Pseudoophonus) griseus (Panzer, 1796), Licinus (Licinus) depressus (Paykull, 1790) and Microlestes maurus maurus (Sturm, 1827). Genera Acinopus Dejean, 1821, Carterus Dejean, 1830 and Licinus Latreille, 1802 were new geographic records for the Sredna Gora Mts. Twelve life form categories were established (7 zoophagous and 6 mixophytophagous). The analysis of the life forms showed a slight predominance of the mixophytophages (38 species; 58%) over the zoophages (28 species; 42%). There were no constant species occurring in all sampling sites (with 100% occurrence). Thirteen species appeared after the harvest (they were absent during the flowering and ripening of the rape), forty-four species disappeared (they were present during flowering and ripening), and twenty-nine species were present in all stages.

And Control

The preference of adult polyphagous ground beetles (Carabidae, Coleoptera) for winter rape seeds was investigated using an indirect method. Rape seeds were scattered around pitfall traps. The catches of carabid beetles in these traps and control traps without seeds were compared. The traps were exposed in two stands of winter wheat. In the wheat stand where overall carabid activity density was high, the presence of rape seeds significantly increased the catches of total seed-eating carabids, and of the two species Pseudoophonus rufipes and Calathus fuscipes. The effect was not significant in the other wheat stand where activity density was low. The aggregation of carabids at places with winter rape seeds indicated the importance of carabid predation on seeds scattered on the ground.

Pitfall Trapping

AbstractWe describe a litter-washing technique for collecting quantitative samples of ground-beetles (Carabidae), and compare the results with those from liner extraction by Tullgren funnels and pitfall (rapping. We also compare performance of four types of pitfall traps across five habitats. Carabid species composition from litter washing and funnel extraction was similar but washing revealed higher densities. Large-bodied species predominated in pitfall samples and small-bodied species predominated in litter samples. Uncovered, round pitfall traps yielded generally higher catches than rectangular or covered, round traps but the pattern was not consistent over all species or the five habitats. Ecological studies of carabid populations and assemblages using pitfall traps may be improved if they are both designed and interpreted in light of the biology of the group and with regard to the deficiencies of pitfall trapping as discussed here and elsewhere.

Pterostichus Melanarius

Carabid beetles are suspected to prey on terrestrial salamanders, but no records of this exist. We examined the behavior of two species of ground beetle (Scaphinotus angusticollis and Pterostichus melanarius) towards juvenile western red-backed salamanders (Plethodon vehiculum) in staged laboratory encounters. We predicted that the beetles would show more aggression towards small (snout–vent length (SVL) ≤30 mm) than large (30 < SVL ≤ 40 mm) juvenile salamanders, as small individuals frequently had missing tails (indicating predation) in the field. Our additional objective was to examine antipredator behavior of P. vehiculum. Scaphinotus angusticollis approached, bit, and climbed on the salamanders more frequently than P. melanarius did, but neither beetle behaved differently towards small and large salamanders. Small juveniles jerked away more frequently than larger individuals when bitten by P. melanarius and when climbed on by S. angusticollis, but otherwise the behavior of salamanders of the two size classes did not differ. After overnight encounters, the injuries on the salamanders included missing toes and tail tips and skin lacerations. Scaphinotus angusticollis consumed an additional six P. vehiculum, and P. melanarius consumed three. The damage was unrelated to the size (SVL) of the salamanders, but all individuals consumed were among the smallest we tested. We suggest that in terms of both its morphology and its behavior, S. angusticollis is better suited than P. melanarius to prey on P. vehiculum, and probably preys on hatchlings in the wild.

River Banks

A comparison was made betweeen the "open" pitfall trap method and quadrat sample method in microhabitats on river banks. The latter method was found to give reliable estimates of the absolute abundance of carabid beetle species. In pitfall traps individuals of the carabid beetle Bembidion schuppelii were over-represented in a sub-optimal microhabitat compared with in optimal ones. The niche-overlap between this species and B. bipunctatum was 0.19 in quadrat samples and 0.59 in pitfall traps. There was no correlation between the relative abundance of individuals of species in quadrat samples and in pitfall traps. Individuals of larger carabid species were highly over-represented compared to smaller ones in pitfall traps, an effect that was independent of diurnal rhythm and life cycle category. Biomass of larger carabid species was also overestimated in pitfall traps compared to that of smaller ones. Imagines were more efficiently captured in pitfall traps than larvae. Pitfall traps had a higher number of species than quadrat samples in all investigated sites. In four of five cases the Shannon-Wiener index gave higher species diversity in pitfall traps than in quadrat samples. It is concluded that the "open" pitfall trap method is inappropriate to study dominance ratio, the ecological role of species and perhaps the species diversity within communities. The general insight into the community structure of carabid beetles may therefore be very biased.
