Fifty years of monitoring changes in the abundance of invertebrates in the cereal ecosystem of the Sussex Downs, England

open access: yesInsect Conservation and Diversity, Volume 17, Issue 5, Page 758-787, September 2024.
Monitoring invertebrates in cereal fields in southern England over 50 years (1970–2019) showed an overall decline in abundance. For taxa at the order/family level, 47% declined in abundance, 16% increased and 37% showed no change. Most functional groups declined, expect for pollinators—whose abundance did not change overall.

The cynipid gall wasp Diplolepis rosae is more successful in North America than in Europe because of enemy release

open access: yesInsect Conservation and Diversity, Volume 17, Issue 5, Page 800-810, September 2024.
We found differences in parasitism rates and gall size between D. rosae populations in North America (Nearctic) and Europe (Western Palearctic). While North American populations have lower parasitism rates, suggesting decreased pressure from natural enemies, they also exhibit significantly larger gall sizes compared with their European counterparts ...

Comparative transcriptome reprogramming in oak galls containing asexual or sexual generations of gall wasps

open access: yesPlant Biology, Volume 26, Issue 5, Page 798-810, August 2024.
Gene expression in the galls induced by the sexual and asexual generation of N. quercusbaccarum and N. numismalis are more similar to each other than the alternate generation of the same species. Abstract Oak gall wasps have evolved strategies to manipulate the developmental pathways of their host to induce gall formation.

Exploring the contribution of the salivary gland and midgut to digestion in the swede midge (Contarinia nasturtii) through a genomics‐guided approach

open access: yesArchives of Insect Biochemistry and Physiology, Volume 116, Issue 3, July 2024.
The larvae of the swede midge, Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), feed on the meristem of brassica crops, resulting in galls that disrupt seed and vegetable production. The salivary gland and midgut transcriptomes of third instar larvae were examined, providing evidence for cooperative extra‐oral and gastrointestinal digestion ...

Redefining Ormyridae (Hymenoptera, Chalcidoidea) with establishment of subfamilies and description of new genera

open access: yesSystematic Entomology, Volume 49, Issue 3, Page 447-494, July 2024.
We redefine the circumscription of Ormyridae based on a phylogenomic dataset and morphological reassessment. Based on the phylogenetic results and comparative morphological assessment, subfamilies are established for the first time. The results support the description of two new genera Halleriaphagus van Noort and Burks, gen.

Responses of the hyper‐diverse community of canopy‐dwelling Hymenoptera to oak decline

open access: yesInsect Conservation and Diversity, Volume 17, Issue 3, Page 430-448, May 2024.
Hymenoptera dwelling in oak canopies are hyper‐diverse. Forest decline reshapes the community of canopy‐dwelling Hymenoptera, and trophic and nesting guilds have contrasting responses to decline. Species relying on ground‐related resources (floral responses and soil microhabitats) are promoted by decline‐induced canopy openness. Abstract Forest decline
