Insect–flower interactions, ecosystem functions, and restoration ecology in the northern Sahel: current knowledge and perspectives

open access: yesBiological Reviews, Volume 100, Issue 2, Page 969-995, April 2025.
ABSTRACT Actions for ecological restoration under the Great Green Wall (GGW) initiative in the northern Sahel have been plant focused, paying scant attention to plant–animal interactions that are essential to ecosystem functioning. Calls to accelerate implementation of the GGW make it timely to develop a more solid conceptual foundation for restoration

A remarkable new species of Zethus Fabricius (Hymenoptera, Vespidae, Eumeninae) from Costa Rica [PDF]

open access: yes, 2009
Porter, new species, is described from Costa Rica. It forms a species group of its own, unique in its grotesquely enlarged male mandibles and reduced clypeus, single mid tibial spur, and in having a medio-apical bulge on the second sternite.

Trap-Nest Design for Small Trap-nesting Hymenoptera [PDF]

open access: yes, 2017
(excerpt) Many solitary bees and wasps construct brood cells in pre-existing natural cavities such as beetle borings or in excavations of pithy stems and twigs like Sambucus and Juglans.

Maximizing Identification Precision of Hymenoptera and Brachycera (Diptera) With a Non‐Destructive DNA Metabarcoding Approach

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
DNA metabarcoding is utilized for efficient bulk sample assessment, yet limited research addresses disparities in species identification methods. We compared diverse clustering and filtering techniques in non‐destructive metabarcoding approach to morphological identification of Brachycera and Hymenoptera.

Diversity of social wasps (Hymenoptera, Vespidae, Polistinae) in three fragments of semideciduous seasonal forest in the northwest of São Paulo State, Brazil Diversidade de vespas sociais (Hymenoptera, Vespidae, Polistinae) em três fragmentos de floresta estacional semidecidual no noroeste do Estado de São Paulo, Brasil

open access: yesRevista Brasileira de Entomologia, 2009
Human exploitation of the forest in the northwest of São Paulo State has generated enormous fragmentation of that forest. Such disturbance has reduced the populations of insects in general.

Flight capacities of yellow-legged hornet (Vespa velutina nigrithorax, Hymenoptera: Vespidae) workers from an invasive population in Europe

open access: yesPLoS ONE, 2018
The invasive yellow-legged hornet, Vespa velutina nigrithorax Lepeletier, 1836 (Hymenoptera: Vespidae), is native to Southeast Asia. It was first detected in France (in the southwest) in 2005.

Predicting the spatio‐temporal dynamics of biological invasions: Have rapid responses in Europe limited the spread of the yellow‐legged hornet (Vespa velutina nigrithorax)?

open access: yesJournal of Applied Ecology, Volume 62, Issue 1, Page 106-118, January 2025.
By predicting the extent of a biological invasion in the absence of timely interventions and comparing this to the current distribution of the yellow‐legged hornet, we found that management measures implemented in these countries appear to have been effective in limiting the spread of the species in Europe.

Prey identification in nests of the potter wasp Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) using DNA barcodes

open access: yesRevista Brasileira de Entomologia, 2014
Prey identification in nests of the potter wasp Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) using DNA barcodes. Geometrid larvae are the only prey known for larvae of the Neotropical potter wasp Hypodynerus andeus (Packard, 1869 ...

Pollinator-attracting semiochemicals of the wasp-flower Epipactis helleborine [PDF]

open access: yes, 2008
The orchid genus Epipactis is represented by 25 species in Europe (Richards 1982). Epipactis helleborine (L.) Crantz is the most common and widely distributed species of the genus (Wiefelspütz 1970), and is a prime example for wasp-flowers, because it is

How to Identify Priority Sites for Invasive Alien Species Policy and Management

open access: yesDiversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Identifying priority species and introduction pathways has long been a goal of national and international policy for reducing and mitigating the impacts of invasive alien species (IAS). Although identifying priority sites for invasion management is included within Target 6 of the Kunming–Montreal Global Biodiversity Framework, methods for ...
