Speciation in Nearctic oak gall wasps is frequently correlated with changes in host plant, host organ, or both

Evolution, Volume 76, Issue 8, Page 1849-1867, August 2022., 2022
Abstract Quantifying the frequency of shifts to new host plants within diverse clades of specialist herbivorous insects is critically important to understand whether and how host shifts contribute to the origin of species. Oak gall wasps (Hymenoptera: Cynipidae: Cynipini) comprise a tribe of ∼1000 species of phytophagous insects that induce gall ...

The ant abdomen: The skeletomuscular and soft tissue anatomy of Amblyopone australis workers (Hymenoptera: Formicidae)

Journal of Morphology, Volume 283, Issue 6, Page 693-770, June 2022., 2022
The ant abdomen is critically understudied, despite its functional, evolutionary, and systematic importance. Using physical dissection, scanning electron microscope, histology, and microcomputed tomography, we provide the first complete treatment of the skeletomusculature, exocrine glands, and other major organs of the abdomen.

Absence of complementary sex determination in two Leptopilina species (Figitidae, Hymenoptera) and a reconsideration of its incompatibility with endosymbiont‐induced thelytoky

Insect Science, Volume 29, Issue 3, Page 900-914, June 2022., 2022
Under complementary sex determination (CSD), if the fertilized eggs are homozygous, they develop into diploid males. Forms of thelytoky induced by endosymbiont lead to genome homozygosity as well. By presenting our results in two cynipid wasp species Leptopilina heterotoma and Leptopilina clavipes, we discuss the presumed incompatibility between CSD ...

Cecinothofagus Nieves-Aldrey & Liljeblad (Hymenoptera, Cynipidae) is likely an endoparasitoid of the gall-maker genus Aditrochus Rübsaamen (Hymenoptera, Pteromalidae) [PDF]

Journal of Hymenoptera Research, 2022
Paraulax Kieffer and Cecinothofagus Nieves-Aldrey & Liljeblad (Cynipidae: Paraulacini) were long supposed to be gall-makers on southern beeches (Nothofagus, Nothofagaceae).

What feeds on Quercus ilex L.? A biogeographical approach to studying trophic interactions in a Mediterranean keystone species

Diversity and Distributions, Volume 28, Issue 1, Page 4-24, January 2022., 2022
Abstract Aim Holm oak (Quercus ilex L.) is regarded as a keystone plant species. Trophic interactions may affect the distribution and abundance of phytophagous species, but the number of arthropod species that use holm oak as a food resource and their levels of host specificity are not yet known.

The Paths of the Galls: Differences in the Ecology and Distribution of Two European Oak Gall Wasps Andricus dentimitratus and Andricus pictus

Journal of Zoological Systematics and Evolutionary Research, Volume 2022, Issue 1, 2022., 2022
Andricus dentimitratus (Rejtõ, 1887) and Andricus pictus (Hartig, 1856) are two European gall wasps (Hymenoptera, Cynipidae) that induce galls on species of Quercus. The distribution and ecological niches of these species have not been studied in detail, though they are known to have a different distribution pattern in the Iberian Peninsula in Europe ...

First records of Charipinae (Hymenoptera, Cynipoidea, Figitidae) aphid hyperparasitoids from Malta [PDF]

, 2015
Charipinae material has been collected from different localities in Malta. Three species have been identified: Alloxysta citripes, Alloxysta pilipennis and Phaenoglyphis villosa in association with two aphids and one parasitoid species.

An integrated phylogenetic reassessment of the parasitoid superfamily Platygastroidea (Hymenoptera: Proctotrupomorpha) results in a revised familial classification

Systematic Entomology, Volume 46, Issue 4, Page 1088-1113, October 2021., 2021
We use a combination of morphological, multi‐locus Sanger sequencing, and whole‐genome sequences to infer the phylogeny of the parasitoid wasp superfamily Platygastroidea. The ancestral hosts of platygastroids were the eggs of Orthoptera. Numerous subsequent host shifts have led to the use of other hosts from an additional eight insect orders and ...

The identity of figitid parasitoids (Hymenoptera: Cynipoidea: Figitidae) of anthomyiid flies in conifer cones

European Journal of Entomology, 2018
Larvae of Strobilomyia flies (Diptera: Anthomyiidae) are serious pests in conifer-seed orchards because they feed on the seed inside the cones. Figitid parasitoids (Hymenoptera: Cynipoidea) of Strobilomyia larvae in conifer cones are commonly reported ...
