چکیده
Environ.Entornol.12:1026-1030(1983) ABSTRACT During ]979 and 1981, populations of ground-dwelling predators and parasites in research and commercial cabbage fields in upstate NewYork were assessed by pitfall trapping tn determine species composition, abundance, phenology, and the impact of insecticides on them. Staphylinidae, Phalangida, Carabidae, and Araneida were consistently the most abundant predaceous taxa. Carabids and Staphylinids together comprised 75.9 and 74.1% of all predaceous or parasitic insects in commercial fields during 1979 and 1981, respectively. One of the 32 species of Carabidae captured, Pterostichus melanarius (Il1iger), accounted for >50% of the total number of Carabidae. Total number of predators and parasites tended to decline from July through September in both treated and untreated fields, but this decline was hastened by the use of broad-spectrum insecticides.

The influence, if any, of 5m wide, feral, herbaceous field borders on pest and beneficial arthropods in commercial cotton, Gossypium hirsutum (L.) (Malvales: Malvaceae), fields was measured through a variety of sampling techniques over three years. In each year, 5 fields with managed, feral vegetation borders and five fields without such borders were examined. Sampling was stratified from the f...
متن کاملA Comparison of the Pitfall Trap, Winkler Extractor and Berlese Funnel for Sampling Ground-Dwelling Arthropods in Tropical Montane Cloud Forests
Little is known about the ground-dwelling arthropod diversity in tropical montane cloud forests (TMCF). Due to unique habitat conditions in TMCFs with continuously wet substrates and a waterlogged forest floor along with the innate biases of the pitfall trap, Berlese funnel and Winkler extractor are certain to make it difficult to choose the most appropriate method to sample the ground-dwelling...
متن کاملInfluence of public road proximity on ground-dwelling insect communities
Ecological studies on road’s impact on wildlife have concentrated on vertebrates although less is known of their effects on invertebrates. The current study presents public road influences on species richness, abundance, and diversity of ground dwelling insects in Arusha National Park in Tanzania. Values from pitfall traps data were generally higher in core habitat than road verge. Nine species...
متن کاملEfficacy of Pitfall Trapping, Winkler and Berlese Extraction Methods for Measuring Ground-Dwelling Arthropods in Moist-Deciduous Forests in the Western Ghats
The present study provides data to decide on the most appropriate method for sampling of ground-dwelling arthropods measured in a moist-deciduous forest in the Western Ghats in South India. The abundance of ground-dwelling arthropods was compared among large numbers of samples obtained using pitfall trapping, Berlese and Winkler extraction methods. Highest abundance and frequency of most of the...

Food availability and acquisition are critical components of a stopover site’s suitability, but we know relatively little about how changes in food availability affect the stopover ecology of migrating landbirds. we examined fruit and arthropod availability in three habitats, studied foraging behavior and diet, and investigated use versus availability for passerines migrating through southweste...
