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.

Successful gall induction on wild roses by gall wasps under lab conditions
Plant galls, induced by insects, remain incompletely understood despite taxonomic and ecological efforts, hindering comprehensive analysis despite modern genetic techniques. Establishment of laboratory‐friendly plant–gall inducer communities is vital, yet past attempts encountered challenges, highlighting the need for innovative approaches.

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.

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.

New Species of Cynipidae (Hymenoptera) from Georgian SSR
New Species of Cynipidae (Hymenoptera) from Georgian SSR. Diakontshuk L. A.— Vestn. zool., 1984, No. 3. Two Eryngium-dwelling species are described as new. Phanacis (Pseudophanacis) eryngi sp. n. is distinct by 12-segment antennae and dilated 3rd sub-

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 ...

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.
