European Journal of Entomology, 2005 At a nest site in Northern Italy of females of the weevil-hunting digger wasp Cerceris arenaria L. (Hymenoptera: Crabronidae) the provisioning activity and predator-prey relationship were investigated, in particular their specialization in choice of prey.

Ecosphere, Volume 10, Issue 1, January 2019., 2019 Abstract Declines in native bee populations can limit pollination services that support native plant communities and global food production. Mitigating the impacts on pollinators and ecosystems requires conservation actions that promote biodiversity and remain practical for producers.

No evidence for pronounced mate-finding Allee effects in the emerald ash borer (Agrilus planipennis Fairmaire) [PDF]
NeoBiotaAllee effects are density-dependent barriers that can impact species establishment and population growth, such as through reduced mating success at low population densities.

The potential of weeds in arable fields to support pollinator assemblages
Weed Research, Volume 65, Issue 1, January/February 2025.Abstract To what extent are weeds on arable land useful to pollinators in an arable‐dominated landscape? We sampled the weed flora in fields under conventional or organic farming in SE Sweden. More specifically, we noted the frequency of flowering among weeds that scored high on a pollinator index, henceforth ‘pollinator‐friendly weeds’.

Ecological Solutions and Evidence, Volume 5, Issue 3, July–September 2024.Our study shows that planting urban green spaces with native plants as a food source for flower‐visiting and leaf‐feeding insects can be a way to promote different insect species in urban areas. Planting or seeding based only on the needs of honey bees is less suitable for the conservation and promotion of insect diversity in urban green spaces, as the

Psyche: A Journal of Entomology, Volume 79, Issue 1-2, Page 61-78, 1972., 1972 The genus Entomognathus contains at least 4o species, half in the Ethiopian and in the Palaearctic, Nearctic, Oriental, and Neotropical regions (Leclercq, 1954, 1955, 1961, 1963; Nouvel and Ribaut, 1956; Krombein, 1963). Relatively little is known about the nesting behaviors, host preferences, or life histories of members of this genus.

Frontiers in Zoology, 2008 Background Host-parasite interactions are among the most important biotic relationships. Host species should evolve mechanisms to detect their enemies and employ appropriate counterstrategies.

Size of emerald ash borer in North Carolina, USA: Preliminary evidence for a sawtooth cline?
Agricultural and Forest Entomology, Volume 26, Issue 1, Page 93-100, February 2024.Abstract We test the hypothesis of Marshall et al. (2013) that in the United States there is a converse Bergmann's cline in body size of Agrilus planipennis (emerald ash borer, EAB), with the largest females (x¯ = 12.6 mm length) collected at the most southern latitudes tested (37° N).
