Network structure and taxonomic composition of tritrophic communities of Fagaceae, cynipid gallwasps and parasitoids in Sichuan, China 中国四川的壳斗科、瘿蜂、和寄生蜂之三級营养生物群落的结构和组成

Insect Conservation and Diversity, Volume 17, Issue 6, Page 1046-1071, November 2024.
We quantified previously unstudied tritrophic gall communities on Fagaceae in Sichuan, China, testing for ‘bottom‐up’ effects of host plant diversity on plant–herbivore and plant–parasitoid interactions. We sampled 176 cynipid gall morphotypes from 23 host plant species, yielding 64 parasitoid morphospecies.

Occurrence of oriental chestnut gall wasp Dryocosmus kuriphilus (Hymenoptera, Cynipidae) in Slovakia - short communication

Plant Protection Science, 2017
During 2014-2016, damage by the oriental chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera, Cynipidae) was found on sweet chestnut trees at 4 localities in Slovakia. Dryocosmus kuriphilus is a specific plant pest on Castanea spp.

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

Insect 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

Insect 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

Plant 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

Archives 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 ...

Dryocosmus kuriphilus (Hymenoptera cynipidae) in Sardegna

, 2014
The chestnut gall wasp Dryocosmus kuriphilus was detected in Sardinia in 2007. Two years later its biological control agent, Torymus sinensis, was released and was started the monitoring of native oak gall wasp parasitoids recruited by D. kuriphilus. Five years after its introduction the exotic parasitoid T.
