Illustrating phylogenetic placement of fossils using RoguePlots: An example from ichneumonid parasitoid wasps (Hymenoptera, Ichneumonidae) and an extensive morphological matrix. [PDF]

open access: yesPLoS ONE, 2019
The fossil record constitutes the primary source of information about the evolutionary history of extant and extinct groups, and many analyses of macroevolution rely on fossils that are accurately placed within phylogenies.

Seven remarkable new fossil species of parasitoid wasps (Hymenoptera, Ichneumonidae) from the Eocene Messel Pit. [PDF]

open access: yesPLoS ONE, 2018
Parasitoid wasps of the family Ichneumonidae are one of the most diverse and species-rich groups of organisms with a worldwide distribution. We here describe seven new ichneumonid fossil species and two new genera from a remarkable insect fossil site ...

The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae) [PDF]

open access: yesParasite, 2018
Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts.

PARASITIC WASPS OF THE PIMPLINAE SUBFAMILY (Hymenoptera, Ichneumonidae) OF AGRICULTURAL LANDSCAPE REFUGIUM HABITATS IN CENTRAL WIELKOPOLSKA [PDF]

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2008
The research was carried out in the years 1991–1994 in agricultural landscape of medium mosaic degree in the area of Łęczyca. It covered parasitoids of the Pimplinae subfamily (Hymenoptera, Ichneumonidae), inhabiting refugium habitats such as ...

New species and new records of Ichneumonidae (Hymenoptera) in Southeast Brazil [PDF]

open access: yesBrazilian Journal of Biology, 2023
During an inventory of Ichneumonidae wasps in the urban area of São Carlos, São Paulo, using Malaise traps, was found the first records in Brazil for Lissonota pseudeleboea Ugalde and Gauld, 2002 and Syzeuctus vedoris Ugalde and Gauld, 2002 (Hymenoptera,

Revision of 18 ichneumonid fossil species (Hymenoptera, Ichneumonidae) highlights the need for open nomenclature in palaeontology [PDF]

open access: yesFossil Record, 2022
The fossil record of Darwin wasps (Ichneumonidae) is extremely understudied relative to their enormous extant diversity, with only around 300 species described.

New records of Pimpla Fabricius, 1804 (Hymenoptera, Ichneumonidae, Pimplinae) from Brazilian northeast [PDF]

open access: yesCheck List, 2021
We record for the first time the species Pimpla croceiventris (Cresson, 1868), P. golbachi (Porter, 1970), and P. sumichrasti Cresson, 1874, belonging to the Pimplini tribe (Ichneumonidae, Pimplinae), in northeastern Brazil.

DNA barcoding resolves quantitative multi‐trophic interaction networks and reveals pest species in trap nests

open access: yesInsect Conservation and Diversity, Volume 16, Issue 5, Page 725-731, September 2023., 2023
Trap nests are a standardised tool so far used for monitoring bees, wasps and their interacting antagonists. With DNA‐barcoding, we now have quantified three‐trophic interaction networks, including antagonists and food resources. Food resources in wasp brood cells revealed so far unknown food species, including crop and forest pests. Construction of up

Determinism and stochasticity in the spatial–temporal continuum of ecological communities: the case of tropical mountains

open access: yesEcography, Volume 44, Issue 9, Page 1391-1402, September 2021., 2021
Ecological communities are assembled in a spatial–temporal continuum. However, we still have a poor understanding of the relative importance of different mechanisms structuring community composition (i.e. beta‐diversity) in space and time. In this study, we start by introducing a conceptual model that capitalizes upon the core‐occasional species ...

A checklist of Pimplinae (Hymenoptera, Ichneumonidae) from the Estação Ecológica dos Caetetus in São Paulo state, with new records of Neotheronia Krieger, 1899 from Brazil [PDF]

open access: yesCheck List, 2017
We provide a list of the Pimplinae from the Estação Ecológica dos Caetetus, São Paulo state, Brazil. A total of 286 specimens belonging to 17 species in 10 genera were collected from December 2002 to May 2004.
