“…DNA markers, such as the mitochondrial cytochrome c oxidase 1 (COI) gene, have become an important species identification tool for insects (Hebert et al 2003a(Hebert et al , 2003b. The importance of DNA sequences in the taxonomy and systematics of Dryinidae as well as the molecular identification of their host associations has been recognized by some researchers (see Mita & Matsumoto 2012;Mita et al 2013;Tribull 2015;Chen et al 2020;Olmi et al 2021). By analyzing COI sequences, Mita & Matsumoto (2012) discovered the male of Gonatopus javanus (Perkins, 1912), a species previously known only from females.…”

Species of the genus Aphelopus Dalman (Hymenoptera, Dryinidae) are important natural enemies of leafhoppers. The genus is relatively diverse in China, with 35 recorded species. In order to further make use of these important parasitoids in biological control programs, species of Aphelopus collected across China are studied using an integrative approach (combined DNA barcoding and morphology). Of the 17 studied species, two are newly recorded from China: A. nivealis Mita & Olmi, 2014 and A. prolatus Mita & Olmi, 2014, and four are described as new to science: A. incognitus Chen, Olmi & Guglielmino sp. nov., A. maculiala Olmi, Chen & Ødegaard sp. nov., A. taianensis Olmi, Ødegaard & Chen sp. nov., and A. zaifui Olmi, Chen & Liu sp. nov. The total number of Aphelopus species known from China is raised from 35 to 39. Keys to the Oriental and Eastern Palaearctic species of Aphelopus are modified to include the new species. Application of DNA barcoding in the species delimitation of Dryinidae is discussed.

“…Many species of Dryinidae display extreme sexual dimorphism, especially in the subfamilies Dryininae and Gonatopodinae (Mita and Matsumoto 2012;Tribull 2015). DNA markers have been shown to be powerful tools for the correct association of the female and male of Dryinidae species with sexual dimorphism (Mita and Matsumoto 2012), exploring intraspecific genetic variation (Mita et al 2013), and molecular phylogeny (Tribull 2015). As the DNA barcode library of Dryinidae is populated with both sexes of additional species, we should be able to accelerate the discovery of host-Dryinidae associations using the approach present in this study.…”

“…It is worth noting that in some cases dryinid larvae protruding from the host's bodies contain hyperparasitoid larvae (Vétek et al 2019) and may result in extracting mixture DNA from the wasp larvae. In such cases, taxon-specific primers (Mita et al 2013) should be used or the Next Generation Sequencing approach should be applied.…”

Application of DNA barcoding confirms the host of Gonatopus viet Olmi, 1986 (Hymenoptera, Dryinidae)

Gonatopus viet Olmi, 1986 was originally described from Vietnam based on a single female. No further distribution records or hosts have been documented since its original discovery. In the present study, this species is newly recorded from China and its host is confirmed as Stirellus capitatus (Distant, 1918) using DNA barcoding techniques. The utility of DNA barcoding to discover host-Dryinidae associations is discussed.

“…Interestingly, some of the 3rd-5th instar hosts could emerge as adults. Mita et al reported that females of the genus Haplogonatopus are wingless, that the migration ability of adult wasps should be highly restricted, but that the passive dispersal of larvae parasitizing hosts may be possible [52]. From 2012 to 2017, we investigated BPHs collected under a light trap in more than 10 regions of southern China, and the results showed that 0.19%-2.24% of the BPHs were parasitized by dryinids (unpublished data).…”

Gonatopus flavifemur (Esaki & Hashimoto) is a common parasitoid of the most important rice pest, the brown planthopper (BPH) Nilaparvata lugens (Stål), in eastern and southeastern Asia. We investigated the parasitism rates, feeding rates, and offspring development of G. flavifemur in association with five instars of BPH nymphs and male and female adults under laboratory conditions (27 ± 1 °C and 70 ± 5% Relative Humidity). The results showed that the life stage of the host significantly affects parasitism, host feeding, and offspring development by G. flavifemur. The parasitism rate was highest on 4th instar nymphs, and the feeding rate was highest on 1st instar nymphs. The cocooning rate on male adult BPHs was significantly lower than that on other stages; however, emergence rates did not significantly differ among the BPH stages. The rate of female offspring upon emergence from 5th instars was higher than other stages. Both the parasitism and host-feeding functional responses of G. flavifemur to different BPH stages fit well with Holling type II models, supporting the results of parasitism and feeding rates and indicating that G. flavifemur would be a good agent for BPH control. In conclusion, G. flavifemur prefers to feed on young nymphs but prefers to parasitize older nymphs. In addition, 5th instar nymphs are favorable to female offspring of the pincer wasp.
