The effect of native forest dynamics upon the arrangements of species in oak forests-analysis of heterogeneity effects at the example of epigeal arthropods
… The spider were collected in a block design by pitfall traps (n=72) in a 4-week interval. To reveal key environmental factors affecting the spider distribution abiotic and biotic habitat parameters (e.g. vegetation parameters, climate parameters, soil moisture) were assessed around each pitfall …

Generalist predators in reduced-tillage corn: predation on armyworm, habitat preferences, and a method to estimate absolute densities
… populations were reduced, through the use of pitfall traps and exclusion arenas, than in the control where predator populations were unaltered. The differences in the proportion of damaged plants and the degree of damage between the predator removal treatment and the control were statistically …

The influence of an umbelliferous understory on the parasites of organic apple orchards in Canterbury
… Adult parasites were trapped using yellow pitfall traps, elevated water traps and aspiration from parsnip inflorescences. 'Delta' pheromone traps were used to trap male codling moth and lightbrown apple moth. Ground dwelling predators were collected by yellow pitfall trap. The influence of …

Comparison of herpetofaunal species composition and response to edge on the Camp Dawson Collective Training Area, Preston County, West Virginia
… 4715.3. Herpetofauna were sampled using pitfall traps with drift fences and double-ended funnel traps, and also from area searches. Redback salamander (Plethodon cinereus), red-spotted newt (Notophthalmus v. viridescens ), eastern American toad (Bufo a. americanus), and wood frog (Rana …

Pest management of billbugs in orchardgrass grown in Virginia
… billbug spring adult. Simultaneously, barrier pitfall traps, a standard method for determining the presence of billbugs in orchardgrass, were used to trap billbug adults in the fields. A comparison of these methods using a Wilcoxon sign-ranked test found no significant differences in the time …

Flame and fodder: how fire and grazing shape arthropod communities in the Okavango Delta
… list of the spiders (Araneae) of Botswana. Using pitfall traps and litter extractions across two seasons, the abundance of the four groups was only fractionally higher in the wet season for the pitfall traps, but litter extractions had large increases in ants, springtails and wasps in the wet …

GROUND BEETLES (COLEOPTERA: CARABIDAE) AS BIODIVERSITY INDICATORS FOR AGE STRUCTURE IN PIEDMONT FORESTS?
… Carabids were collected monthly through pitfall traps from March 2009 through February 2010 from 33 sites representing 5 forest classes approximately 0, 10, 50, 85, and 150 years old. 2,568 individuals were collected, representing 29 genera and 66 species. Carabid species diversity was …

Vertebrated Richness of Waterfowl Production Areas in the Prairie Pothole Region of Minnesota
… and reptiles were sampled using baited snap traps, pitfall traps, and funnel traps. Larger mammal presence was determined from field observations, tracks, droppings, dens, or lodges. Diversity was measured using species richness. While it appeared to have the highest species richness, the …

Impact of mustards (Brassicaceae) grown as cover crops on non-target arthropod communities
… crop treatments. Insects were collected from pitfall traps during four sampling periods in 2008: 06-09 April, 10-12 June, 24-27 June, and 17-19 July. Soil samples were collected in 2008 on 18 April, 02 June (1 week after planting of mustards), 29 June (shortly before incorporation of …

Herptile Abundance and Diversity in Response to Seasonal Burning on a Central Texas Ashe Juniper-Live Oak Savanna
… trapping line, consisting of 1 drift fence, 2 pitfall traps and 2 funnel traps, was established on 12 treatment (6 on each burn treatment) and 6 control plots (unburned), for a total of 18 trap lines. Eighty-two individual herptiles, representing 8 snake, 3 lizard and 2 toad species were …

The Relationship of Herpetofaunal Community Composition to an Elephant (Loxodonta Africana) Modified Savanna Woodland of Northern Tanzania, and Bioassays with African Elephants
… 2007 to March 2008, we erected drift fences and pitfall traps to sample herpetofaunal community and examined species richness and diversity within the damaged areas and in an exclusion plot. I captured 143 individuals comprising 13 species of reptiles in the order Sauria and nine species of …

Integrated pest management of the banana weevil, Cosmopolites sordidus (Germar), in South Africa
… monitored with semiochemical (Cosmolure®) baited pitfall traps. Traps were moved monthly to a random independent location, or left in situ for the duration of the experiment. The ontogeny was determined by dissecting felled plants and toppled plants (up to 2-week-old fresh residues), and harvested …

THE STATUS OF INVASIVE DUSKY SLUG (ARION) SPECIES IN THE UPPER GREAT LAKES: A MOLECULAR APPROACH
… Lake Michigan, and Lake Huron using beer-baited pitfall traps from May to September of 2022. I collected slugs at one location in Marquette, Michigan biweekly, a total of eight times, throughout the summer to monitor fine-scale slug activity. I found <em>Arion fuscus </em>at 9 of the 11 locations …
