Aculeate Hymenoptera (Hymenoptera, Aculeata) Inhabiting Trap Nests in Crimea

Entomological Review, 2019
Trap nests for aculeate Hymenoptera were exposed during 15 years (2002–2016) in 80 localities of Crimea. A total of more than 500 trap nests containing about 25 000 cavities were used. As a result, 6 895 nests of 97 species from 9 families of Hymenoptera were obtained: Pompilidae (5 species / 118 nests), Vespidae (27/1201), Ampulici-dae (1/6 ...

Biology of Trypoxylon in Trap Nests in Wisconsin (Hymenoptera: Sphecidae)

American Midland Naturalist, 1967
Four species of Trypoxylon were collected in sumac trap nests in Wisconsin: T. frigidum Smith, rubrocinctum Packard, striatum Provancher, and tridentatum Packard, the latter being found in one nest only. Nests of each species consisted of a linear series of cells constructed in borings of 3/16-, 1/4- and 5/16-inch diameter.

Biology of Ancistrocerus Antilope (Panzer) (Hymenoptera, Vespidae) in Trap-Nests in Wisconsin

Annals of the Entomological Society of America, 1956
An opportunity was taken to study the nesting biology of Ancistrocerous wasps when they were found utilizing trap-nests which had been placed in the field for research primarily with Megachilidae. Most of the trap-nests were located in northern Wisconsin at the Ashland Branch Experiment Station or localities not more than 25 miles distant from the ...

Trap nests for bees and wasps to analyse trophic interactions in changing environments—A systematic overview and user guide

open access: yesMethods in Ecology and Evolution, 2018
1. Trap nests are artificially made nesting resources for solitary cavity‐nesting bees and wasps and allow easy quantification of multiple trophic interactions between bees, wasps, their food objects and natural enemies. 2.

Spillover of trap-nesting bees and wasps in an urban–rural interface

Journal of Insect Conservation, 2014
A mismatch of resource availability in certain periods can lead to spillover of insects between habitats, resulting in temporal differences in insect diversity. Urban gardens are important anthropogenic habitats but it is unknown whether, when and why spillover of beneficial insects occurs between gardens and agricultural habitats.

Trap-Nesting Hymenoptera and Their Network with Parasites in Recovered Riparian Forests Brazil

Neotropical Entomology, 2017
Different aspects of human activities can cause environmental change that endanger species persistence, alter species distributions, and lead to changes in antagonistic and mutualistic interactions, whereas deforestation and flooding of riparian forest results in landscapes consisting of patchily distributed riparian forest fragments in a matrix of ...

Bee-Rustling on the Range: Trap-Nesting for Pollinators on Public Lands

Natural Areas Journal, 2017
A significant portion of world food supply depends on the action of pollinators, which for most crops are primarily domesticated and “wild” bees. Over 75% of pollinator value in the USA accrues through the actions of domesticated honey bees. However, the number of commercial honey bee colonies in the USA has been declining for seven decades due to ...

Effect of shading on trap nest utilization by hole-nesting aculeate Hymenoptera

The Canadian Entomologist, 2004
For many years, trap nests have been used to study hole-nesting bees and wasps (aculeate Hymenoptera) and to monitor their diversity and abundance (Krombein 1967; Danks 1971; Godfrey and Hilton 1983; Frankieet al.1998). Trap nests are valuable for environmental assessment (Tscharntkeet al.1998) and for agriculture through improved pollination by bees ...

Biology of Apoidea Taken in Trap Nests in Northwestern Ontario (Hymenoptera)

The Canadian Entomologist, 1965
AbstractOsmia atriventris Cr. and Megachile relativa Cr. are the most abundant bees accepting trap nests in the Black Sturgeon Lake area of Ontario. Hylaeus ellipticus (Kby.), H. verticalis verticalis (Cr.), Hoplitis albifrons albifrons (Kby.), and H. cylindrica (Cr.) are common while Hylaeus basalis (Sm.), Osmia proxima Cr., M.

Biology of Rygchium foraminatum in Trap-Nests in Wisconsin (Hymenoptera: Vespidae)

Annals of the Entomological Society of America, 1964
Trap-nests consisting of holes bored in sumac stems were used to study the nesting biology of R. foraminatum (Saussure) in Wisconsin. Typical nests consisted of a linear series of provisioned cells and empty spaces separated by clay partitions. The means of the lengths of cells ranged from 14.9 to 17.1 mm, and those of the spaces 6.2 to 7.9 mm ...
