The 2017-2019 report (in Romanian) can be found here.

The complete list of parasitoids (Insecta: Hymenoptera, Diptera) associated with Nezara viridula is shown in the table below.

The reconstruction of the phyllogenetic relationships between the analyzed Trissolcus species (Hymenoptera: Platygastroidea) is presented in the figure below. Bootstrap values are relatively high, except for the clade including the South Korean specimens (circle), because of their high genetic distance. Preliminary results indicate 14 clades plus outgroup.

The results regarding the species delimitation among the analyzed Trissolcus specimens after applying three algorithms (MPTP, PTP, Single/Multiple Threshold) as well as morphology (using the key of Talamas et al., 2017) are illustrated below.

The analysis of the morphological characters revealed the presence of six species of Trissolcus: T. cultratus (3♀), T. japonicus (1♀), T. rufiventris (12♀& 6♂) T. scutellaris (1♀ & 1♂) T. semistriatus (26♀ & 8♂), and Trissolcus sp. (1♂). Trissolcus japonicus is illustrated below.

The taxonomic revision of Acroclisoides sinicus (Hymenoptera: Chalcidoidea: Pteromalidae) (below: A, B, female; C, D, male) an oophagous parasitoid or hyperparasitoid of various species of stink bugs, including N. viridula, revealed its presence (apart from Asia) in a much wider areal than previously known. Our team, together with colleagues from Italy, USA, and Switzerland, characterized the species using morphological features and molecular markers, which will enhance the chances of correct future identifications.

The ML phylogenetic reconstruction of Anastatus spp. (Hymenoptera: Chalcidoidea: Eupelmidae), using the Multiple Threshold algorithm of GMYC (below) gives 25 different species.
