Network structure and taxonomic composition of tritrophic communities of Fagaceae, cynipid gallwasps and parasitoids in Sichuan, China

Insect Conservation and Diversity (2024)

Zhiqiang Fang Chang‐Ti Tang Frazer Sinclair György Csóka Jack Hearn

Abstract A key question in insect community ecology is whether parasitoid assemblages are structured by the food plants of their herbivore hosts. Tritrophic communities centred on oak‐feeding cynipid gallwasps are one of the best‐studied tritrophic insect communities. Previous work suggests that host plant identity is a much stronger predictor of oak–cynipid interactions than of cynipid–parasitoid interactions. However, these relationships have not been formally quantified. We reason that the potential for ‘bottom‐up’ effects should increase with host plant phylogenetic diversity. We, therefore, generated quantified interaction network data for previously unstudied tritrophic cynipid communities in Sichuan, China, where, in addition to Quercus , cynipid host plants include Castanea , Castanopsis and Lithocarpus . We characterise these communities taxonomically and compare the extent to which host plant taxonomy predicts plant–herbivore and plant–parasitoid associations. We sampled 42,620 cynipid galls of 176 morphotypes from 23 host plant species, yielding over 4500 specimens of 64 parasitoid morphospecies. Many parasitoids were identifiable to chalcidoid taxa present in other Holarctic oak cynipid communities, with the addition of Cynipencyrtus (Cynipencyrtidae). As elsewhere, Sichuan parasitoid assemblages were dominated by generalists. Gallwasp–plant interaction networks were significantly more modular than parasitoid–plant association networks. Gallwasps were significantly more specialised to host plants (i.e. had higher mean d' values) than parasitoids. Parasitoid assemblages nevertheless showed significant plant‐associated beta diversity, with a dominant turnover component. We summarise parallels between our study and other Fagaceae‐associated cynipid communities and discuss our findings in light of the processes thought to structure tritrophic interactions centred on endophytic insect herbivores.

Cynipid wasps inducing galls on plants of the genusPicris(Asteraceae) in Europe, with a description of a new species ofPhanacisFoerster (Hymenoptera: Cynipidae) from the Iberian Peninsula

Annales de la Société entomologique de France (N S ) (2008)

J. L. Nieves‐Aldrey Íñigo Sánchez Bruno Massa J. F. Gómez

Abstract The cynipid species (Hymenoptera: Cynipidae), inducing galls on plants of the genus Picris (Asteraceae) in Europe, are revised. A key for the identification of adult wasps and galls of the three known species is provided. Phanacis helminthiae (De Stefani) is recorded from Sicily for the first time since its description, and re-described with newly collected materials. The final instar larva of Phanacis caulicola is described and new biological data on the sex ratio and life-cycle of this species are given. A new species, Phanacis comosae nov. sp., is described from the Southwest portion of the Iberian Peninsula. The new species is closely allied to P. caulicola and induces conspicuous galls in flower receptacles of Picris comosa.

Life history of Parnips and the evolutionary origin of gall wasps

Journal of Hymenoptera Research (2018)

Fredrik Ronquist Johan A. A. Nylander Hege Vårdal J. L. Nieves‐Aldrey

By mechanisms that are still unknown, gall wasps (Cynipidae) induce plants to form complex galls, inside which their larvae develop. The family also includes inquilines (phytophagous forms that live inside the galls of other gall inducers) and possibly also parasitoids of gall inducers. The origin of cynipids is shrouded in mystery, but it has been clear for some time that a key group in making progress on this question is the ‘figitoid inquilines’. They are gall-associated relatives of cynipids, whose biology is poorly known. Here, we report the first detailed data on the life history of a figitoid inquiline, the genus Parnips . Dissections of mature galls show that Parnipsnigripes is a parasitoid of Barbotiniaoraniensis , a cynipid that induces single-chambered galls inside the seed capsules of annual poppies ( Papaverrhoeas and P.dubium ). Galls with pupae of Parnipsnigripes always contain the remains of a terminal-instar larva of B.oraniensis . The mandibles of the terminal-instar larva of P.nigripes are small and equipped with a single sharp tooth, a shape that is characteristic of carnivorous larvae. The weight of P.nigripes pupae closely match that of the same sex of B.oraniensis pupae, indicating that Parnips makes efficient use of its host and suggesting that ovipositing Parnips females lay eggs that match the sex of the host larva. Dissection of young galls show that another species of Parnips , hitherto undescribed, spends its late larval life as an ectoparasitoid of Iraellahispanica , a cynipid that induces galls in flowers of annual poppies. These and other observations suggest that Parnips shares the early endoparasitic-late ectoparasitic life history described for all other cynipoid parasitoids. Our findings imply that gall wasps evolved from parasitoids of gall insects. The original hosts could not have been cynipids but possibly chalcidoids, which appear to be the hosts of several extant figitoid inquilines. It is still unclear whether the gall inducers evolved rapidly from these ancestral parasitoids, or whether they were preceded by a long series of intermediate forms that were phytophagous inquilines.
