  "account": "Stink bugs, belonging to the Hemiptera Pentatomidae family, pose significant threats to agriculture in various parts of the world, including France. Among the most notorious invaders is Halyomorpha halys, which has swiftly spread across the country, causing damage to crops such as hazelnuts, apples, and vegetables. Other native, polyphagous species like Nezara viridula, Palomena prasina, and Graphosoma italicum are also making a comeback, affecting a wide range of crops due to shifts in farming practices and climate.\n\nEgg parasitoids hold potential as effective biological control agents against these pests, whether through conservation, augmentation, or introduction. However, the true potential of these natural enemies remains unclear due to limited extensive surveys and potential taxonomic challenges. This investigation seeks to fill this knowledge gap by synthesizing data from multiple egg parasitism studies on Pentatomidae in France, and employing a large-scale DNA Barcoding technique (involving 2000 individuals) for the identified parasitoids.\n\nThe results reveal a rich diversity of egg parasitoids, with some taxonomic ambiguities and molecular inconsistencies that require further investigation. Of the three families of egg parasitoids discovered (Encyrtidae, Eupelmidae, and Scelionidae), Scelionidae stood out as the most abundant and diverse, hosting nine species of Trissolcus (including the adventive species Tr. japonicus and Tr. mitsukurii) and four Telenomus species, some of which remain unidentified to species level. Scelionidae dominated the parasitoid communities associated with most Pentatomidae hosts, with the exception of H. halys, where the eupelmid Anastatus bifasciatus emerged as the most prevalent species.",
  "summary": "Stink bugs (Hemiptera Pentatomidae) are major agricultural pests worldwide, including both native and invasive species. In France, for instance, Halyomorpha halys has rapidly expanded its range, affecting key crops such as hazelnuts, apples, and vegetables. Meanwhile, several native, polyphagous species - Nezara viridula, Palomena prasina and, to a lesser extent, Graphosoma italicum - are…",
