“…Although the gall and adult morphology of D . zhuili are similar to those of the chestnut gall wasp Dryocosmus kuriphilus Yasumatsu, which reproduces asexually without males, D. zhuili reproduces bisexually and, unlike all other species of Cynipini, is considered to have one sexual generation in 1 yr (Zhu et al 2015, Pang et al 2018). In addition, Dryocosmus nanlingensis Abe, Ide, and Odagiri was described based only on one male from China, indicating that it is the sexual generation (Abe et al 2014).…”

Heterogony was confirmed in the cynipid genus Cycloneuroterus Melika and Tang in rearing experiments with DNA barcoding. These experiments involved Cycloneuroterus gilvus Tang and Melika, which was previously only described from the sexual generation adult. The first rearing experiment was conducted using unidentified asexual generation females collected from Quercus gilva Blume, and gall formation by the sexual generation offspring was confirmed on folded or unfolded young leaves of Q. gilva. The second experiment was conducted using sexual generation males and females reared from the leaf galls collected from Q. gilva, and gall formation by the asexual generation offspring was observed on leaves of Q. gilva. Based on the morphological features of the sexual generation adults and galls, this species was identified as C. gilvus. The species identity of wasp specimens of sexual and asexual generations used in the rearing experiments was cross-checked using DNA barcoding with the partial sequences of the cytochrome c oxidase subunit I (COI) region (658 bp). The asexual generation adult and gall of C. gilvus are described based on these results. The importance of ‘closing the life cycle,’ in this case a demonstration of heterogony, in oak gall wasps (Cynipini) is discussed.

“…The close association between the presence of Wolbachia and thelytoky was demonstrated in two tribes of the Cynipidae, the Aylacini (herb gall wasps) and the Diplolepidini (rose gall wasps) (Plantard et al, 1998, 1999). Cynipini, or the oak gall wasps (gall inducers on Quercus and its allied genera of Fagaceae), is the most species‐rich tribe of Cynipidae and currently comprises about 1 000 known species in 41 genera (Ronquist et al, 2015; Pang et al, 2018). Most species of Cynipini reproduce by cyclical parthenogenesis, with a strict alternation between one arrhenotokous generation and one thelytokous generation (Stone et al, 2002).…”

“…The Oriental chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), originates from China, and has expanded its distribution to Japan and Korea (Yasumatsu, 1951), Nepal (Ueno, 2006), North America (Payne et al, 1975), and Europe (Brussino et al, 2002). It causes significant damage to the chestnut industry in its native China as well as in places where it has been accidentally introduced (Rieske, 2007; Bosio et al, 2010; Zhu et al, 2015; Pang et al, 2018). As a globally invasive insect pest, it is harmful to almost all species belonging to the Castanea genus (chestnuts, Fagaceae) (Brussino et al, 2002; Rieske, 2007; Zhang, 2009).…”

The Oriental chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), is a global invasive pest that causes serious damage to almost all chestnut species belonging to the Castanea genus (Fagaceae). Dryocosmus zhuili Liu et Zhu is a recently described sibling species of D. kuriphilus, which induces galls on Castanea henryi (Skan) Rehd. et Wils. There are many indigenous parasitoid species in China which play an important role in the natural regulation of their population dynamics. Wolbachia is a maternally inherited α‐proteobacterium widely found in arthropods. This study screened for the presence of Wolbachia in the two chestnut gall wasps and in six parasitoid species from 12 populations, to investigate the prevalence patterns of Wolbachia in the chestnut gall wasp‐parasitoid communities. We found that D. zhuili and four parasitoid species were infected with Wolbachia; among them, all individuals of the two populations of Megastigmus sp. had multiple Wolbachia infections. By using multilocus sequence types to characterize bacterial strains, three new sequence types were identified. The Wolbachia strains infecting D. zhuili (ST‐507), Torymus sinensis Kamijo (ST‐508), and Sycophila variegata (Curtis) (ST‐508) belonged to supergroup A, whereas the Wolbachia strain infecting Megastigmus nipponicus Kamijo (ST‐503) belonged to supergroup B. Our results also suggested that horizontal transmission of Wolbachia occurs between chestnut gall wasps and their parasitoids. Moreover, multiple Wolbachia infections of Megastigmus sp. may be due to gene recombination and horizontal transmission.

“…In addition to gall formers, the Cynipidae also include phytophagous inquilines, which live inside the galls induced by another species. Dryocosmus liui Pang, Su & Zhu (2018) is a recently described species from Hunan Province in central south of China, forming galls on branches of Castanopsis tibetana Hance. The genus Dryocosmus Giraud is of particular interest among Cynipidae because of its wide distribution, use of host plants belonging to multiple genera in the beech family (Fagaceae), and include a species that is completely parthenogenic ( Buffington & Morita, 2009 ; Zhu et al.…”

Mitochondrial genomes (mitogenomes) have been widely used in comparative and evolutionary genomics, molecular evolution, phylogenetics, and population genetics, but very limited information is available for the family Cynipidae. In this report, we describe the mitogenome of Dryocosmus liui Pang, Su et Zhu, providing the first complete mitogenomic data for a cynipid gall wasp species. The mitogenome of D. liui is 16,819 bp in length, and contains the typical set of 37 genes. Two control regions were detected, with the second being a perfect inverted repeat of the major portion of the first. Gene rearrangements were found in transfer RNA (tRNA) genes, protein-coding genes (PCGs) and ribosomal RNA (rRNA) genes, compared with the putative ancestral mitogenome. Similar to two other Cynipidae species with mitogenome data available, D. liui has a novel tRNA gene cluster trnL1–trnI–trnL2–trnW–trnM–trnQ between nad1 and nad2. Phylogenetic analysis based on sequences of PCGs and rRNA genes with D. liui included obtained topologies identical to previous studies supporting the a relationship of (Cynipoidea , (Platygastroidea, Proctotrupoidea)) within the monophyletic Proctotrupomorpha and (Cynipidae, Figitidae), Ibaliidae) within the Cynipoidea.
