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 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.

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.

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.

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.

Little is known about the distribution of organisms in transitional areas, overall because of the lack of understanding regarding each species’ specificity to the diversity of microhabitats found in these areas and effective ways to sample organisms in these regions. Therefore, in this study we aimed to inventory the bee species in a transitional Cerrado-Amazon area in the state of Pará, Brazil, evaluating the effects of three different sampling methods. We used six fragments, sampled in two different seasons with three sampling methods (arboreal pitfalls with urine, scent traps, and pan traps). The specimens were identified and we used accumulation curves to measure the effectiveness of each method. In total, we sampled 68 bee species, where 53 were exclusively from one single sampling method. The pitfall traps were those with reached the highest species richness among all three sampling methods analyzed, followed by the scent traps and pan traps, respectively. Despite the efficiency and generality of the bee groups we found, the pitfall method does not cover specific bee groups as the Euglossini bees, almost exclusively attracted to scent traps. Therefore, we suggest that studies using pitfalls with urine should be performed in other biomes to evaluate the efficiency of this method in future bee surveys.

The influence of season, ground temperature and habitat on diurnal epigeic activity of ground beetles (Coleoptera: Carabidae) in floodplain forest and neighboring clear-cut area was studied in late spring and early autumn by pitfall trapping. Among the material collected were 35 species of ground beetles. We recorded a significant influence of daytime factors on epigeic activity in 16 species. The epigeic activity of 13 species was co-affected by the temperature of the soil surface. The activity of some species differed, depending on season and locality.

Carabid beetles are natural enemies of insects pests and are weed seeds predators. They have been often used to study the ecological effects of different agricultural measures, because they are highly sensitive to habitat change. The Carabid beetle fauna is little known in Algeria, especially in agrosystems, thus we undertaken a study of this group of insects in citrus orchard located in the city of Guelma. Carabids were collected by pitfall trapping from december 2017 to may 2018. A total of 16 beetle species and 1072 individuals were recorded. The dominant species were consecutively as follows: Amara subconvexa , Brachinus sclopeta, Phyla rectangulum, Harpalus siculus and Percus lineatus. The data of the species traits as food preference and flying ability show that carnivorous and macropterous species dominate in the study area. The activity of the species was mainly observed during the spring period.

AbstractPitfall trapping was carried out in a southern Ontario apple orchard for 3 years. The three commonest carabids collected were Harpalus affinis Schr., Pterostichus melanarius Ill., and Amara spp. Variation in activity was related to mean air temperatures in P. melanarius but not in the other two species. The use of pitfall traps in enclosures showed that none of the above species use flight as the principal means of locomotion. Immature H. affinis adults probably undergo a dispersal flight in July. Amara spp. and P. melanarius both fly within the orchard to some extent.

Trap Size

Apart from experimental design, the selection of pitfall trap size, collecting fluid and habitat type sampled may also influence the capture efficiency of the method. We combined three field studies from two very different geographic areas, in which the efficiency of pitfall traps, using carabid beetles (Coleoptera: Carabidae), is evaluated. First, we showed that ethylene-glycol is a more efficient collecting fluid compared to commercial anti-freeze, paraffin and salt water in collecting beetles in a forest patch in South Africa. Second, we showed that larger traps (90 mm mouth diameter) are more efficient in collecting carabids than small traps (65 mm) in a meadow in Finland. We also showed that for these large traps, commercial vinegar was a better collecting fluid than propylene-glycol, but that for small traps, propylene-glycol was superior to vinegar in collecting carabids. Finally, we showed that the trappability of Pterostichus oblongopunctatus and Carabus hortensis differed in enclosures placed into two different habitat types (a forest and a clear-cut in Finland), while trappability did not differ significantly for two other species (Calathus micropterus and Pterostichus niger) in these habitat types. However, for the two Pterostichus species studied, the catches in traps placed in the centre of the enclosures were slightly higher in the clear-cut, compared to the forest, and catches were higher in enclosures with rich field-layer vegetation, compared to enclosures with poor vegetation. The three studies re-emphasise the uncertainties of using pitfall traps in ecological studies. However, with careful planning and standardisation to help avoid erroneous interpretations, pitfall trapping is an invaluable method for the field ecologist.
