The purpose of this application, under Articles 23.9.3 and 75.6 of the ICZN Code, is to conserve the current usage of the generic name Platygaster Latreille, 1809 (Hymenoptera, Platygastridae) by designating a neotype for the type species Scelio ruficornis Latreille, 1805. The current usage of Platygaster is threatened because the name-bearing type...
The invasive stink bug Halyomorpha halys has become an important pest of many crops, causing severe economic losses to farmers. Control of the pest mainly relies on multiple applications of broad-spectrum insecticides, undermining the integrated pest management programs and causing secondary pest outbreaks. In the native area, egg parasitoids are t...
We report the first detection of Trissolcus japonicus in southwestern France. A total of almost 3000 sentinel and 700 field-laid egg masses of Halyomorpha halys were exposed or collected in the administrative region of Nouvelle-Aquitaine in 2022 and 2023. A total of 12 and 44 specimens of T. japonicus emerged from one and two egg masses in 2022 and...
In recent years, the collection of eggs of stink bugs (Pentatomidae) has intensified because of the attention given to egg parasitoids in classical biological control strategies against Halyomorpha halys (Stål) in Europe. Several specimens belonging to the genus Telenomus Haliday emerged from field-collected pentatomid eggs. Taxonomic knowledge to...
Serbia has recently begun facing a serious problem with the Brown Marmorated Stink Bug, Halyomorpha halys (Stål), which was first recorded in October 2015. This species belongs to the Pentomidae family and is notorious for causing extensive damage to plants. During the winter, it tends to gather in urban areas, such as houses and different man-made...
Findings and identification of new species of beneficial organisms (native, non-native) such as parasitoids, predators and predatory mites can be important for the biological control of agricultural pests. By finding and confirming new species of beneficial insects and mites in Slovenia, if they are also on the EPPO Positive List, we can add them t...
High resolution images are provided for type specimens of Platygastroidea (Hymenoptera: Apocrita) in the Hope Entomological Collections, Oxford University.

The distribution of the two alien species, Zelus renardii Kolenati, 1857 and Nagusta goedelii (Kolenati, 1857) in Sardinia is summarized and commented, with the addition of some new records, including the first populations of Z. renardii in the northern and central-west of the island (Sassari and Oristano) and the first finding of N. goedelii in ce...
Halyomorpha halys (Stål) (Hemiptera, Pentatomidae) was accidentally introduced to North America and Europe, becoming a key pest of many important crops. In its native range, it is attacked by egg parasitoids, including Trissolcus japonicus (Ashmead), considered to be the main species, and T. mitsukurii (Ashmead) (Hymenoptera, Scelionidae). Trissolc...
Zelus renardii is a species of assassin bug (Hemiptera Heteroptera Reduviidae) native to Central and North America and spread in many areas of the world, including Europe, where it is rapidly expanding especially in the Mediterranean part. In Italy this species was recorded for the first time in 2013 and since then it has spread to almost the entir...
Unintentional introduction of natural enemies has increased in recent years due to a massive rise in global trade and tourism. One such natural enemy is the Asian egg parasitoid Trissolcus japonicus, a promising agent for classical biological control of Halyomorpha halys. In Europe, adventive T. japonicus populations have been detected in Switzerla...
Green shield bug (GSB), Palomena prasina L. (Hemiptera: Pentatomidae), is an important pest of hazelnut orchards causing significant yield and quality losses in Turkey. The application of insecticides is the only option to manage GSB in Turkey; however, effective and alternative eco-friendly control practices are needed to manage the pest in the co...
For over a decade, the invasive pest Drosophila suzukii (Matsumura) has threatened the soft-skinned fruit production worldwide, causing increased management costs and yield losses. Current integrated pest management (IPM) exploits different control tools but relies mainly on insecticides. The local natural
enemy community mostly consists of genera...
The brown marmorated stink bug Halyomorpha halys is a polyphagous insect, which has a devastating impact on agricultural production in many countries. The alteration of symbiont vertical transmission, by removing symbionts from stink bug eggs (symbiotic control), has been recently introduced in control programmes against this insect. A major advant...
An insecticide-free control tool against the BMSB Halyomorpha halys is symbiotic control, i.e. the interruption of vertical transmission of the obligate bacterial symbiont ‘Candidatus Pantoea carbekii’. The potential related to symbiotic control application to counteract H. halys was assessed under laboratory and field conditions. The micronutrient...
The monotypic genus Latonius Kononova, 1982 (Platygastroidea, Scelionidae), was described from a single female specimen collected in southern Ukraine. It somewhat resembles Trissolcus Ashmead but has a distinctive claval formula. The only species in the genus, Latonius planus Kononova, 1982, is lacking any details regarding biology, sexual dimorphi...
We report the first detection of Trissolcus mitsukurii in France. More than 1860 sentinel
egg masses of Halyomorpha halys (BMSB) were exposed in the field during the 2018–2020 period, and 12 specimens of T. mitsukurii emerged from one egg mass. Their taxonomic identification was confirmed both by morphological and molecular analysis. Trissolcus mit...
Trissolcus kozlovi (Hymenoptera: Scelionidae) emerged from field-laid eggs of Halyomorpha halys (Hemiptera: Pentatomidae) in North Italy, and it emerged in significantly higher numbers from fresh H. halys eggs compared to other native scelionids. Since few data on T. kozlovi are available, its host-specificity and some biological traits were invest...
The brown marmorated stink bug Halyomorpha halys is an invasive agricultural pest with a worldwide distribution. Classical biological control has been identified as the most promising method to reduce the populations of H. halys. Adventive populations of two candidates for releases, Trissolcus japonicus and Trissolcus mitsukurii, have recently been...
The Orange Spiny Whitefly (OSW) Aleurocanthus spiniferus (Hemiptera: Aleyrodidae) represents a new serious threat to Citrus spp., grapevine and ornamental plants in the whole Mediterranean area. Such threat urgently calls for the development of a sustainable control strategy, including insecticides compatible with biological control, and applicable...
The invasion of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) has caused severe economic damage in crops in North America and Europe, motivating research to identify its natural enemies, both in native and invaded areas. In its Asian native range, the main natural enemies are egg parasitoids, among which the most effective are Trissolcus japon...
Sustainable strategies such as classical or augmentative biological control are currently being evaluated for the long-term management of the alien invasive pest Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). A three-year study carried out in northeastern Italy was performed to investigate the distribution and field performance of the H. halys...
A 3-year survey was carried out to assess the impact of egg parasitoids on Halyomorpha halys in northern Italy. In total, 1826 H. halys egg masses were collected in the 3 years, and parasitoid adults emerged from 12% of eggs in 2016 and 2017, and from 21% in 2018. Anastatus bifasciatus was the main species emerging from H. halys eggs at all sites a...
Accurate identification of parasitoids is crucial for biological control of the invasive brown marmorated stink bug, Halyomrpha halys (Stål). A recent work by Talamas et al. (2017) revised the Palearctic fauna of Trissolcus Ashmead, egg-parasitoids of stink bugs, and treated numerous species as junior synonyms of T. semistriatus (Nees von Esenbeck)...
The olive fruit fly, Bactrocera oleae, is considered the main olive pest worldwide, and has been the target of biological control programmes through the release of the braconid parasitoid Psyttalia concolor. Laboratory tests were performed to evaluate the influence of distance from the host on parasitisation, placing larvae of the substitute host C...
Abstract: Most phytophagous insects on cultivated olives, Olea europaea L. subsp. europaea var. europaea, in South Africa are native and come from the local wild olive tree, Olea europaea subsp. cuspidata. This paper presents the first qualitative and comparative data regarding the phytophagous seed wasps on cultivated and wild olives. From 2009 to...
The wild olive seed weevil, Anchonocranus oleae Marshall, 1912 was not found after its description and the study of its biology by Silvestri in 1915. Recently, A. oleae larvae were found alive inside the kernels of wild olives (O. europaea subsp. cuspidata) collected from trees between 2009 and 2012 in the Western Cape, South Africa. No weevil larv...
Rapisarda C.-Environmental factors impact and incidence of parasitism of Psyllaephagus bliteus Riek (Hymenoptera Encyrtidae) on populations of Glycaspis brimblecombei Moore (Hemiptera Aphalaridae) in Mediterranean climatic areas.
