The accidental endogenization of viral elements within eukaryotic genomes can occasionally provide significant evolutionary benefits, giving rise to their long-term retention, that is, to viral domestication. For instance, in some endoparasitoid wasps (whose immature stages develop inside their hosts), the membrane-fusion property of double-stranded DNA viruses have been repeatedly domesticated following ancestral endogenizations. The endogenized genes provide female wasps with a delivery tool to inject virulence factors that are essential to the developmental success of their offspring.

Article Synopsis
  • Despite extensive taxonomic research, the exact size and diversity of global faunas and floras remains largely unknown, with many inventories providing incomplete data.
  • A study focused on Swedish insects reveals over 3,000 new species, including 301 new to science, showcasing hidden diversity within one of Europe’s most well-documented faunas.
  • Using three independent methods, researchers estimate that the Swedish insect fauna comprises around 33,000 species, with significant findings indicating that many new species belong to decomposer or parasitoid groups, highlighting taxonomic biases in current knowledge.

Background: Parasitic wasps in the family Braconidae are important regulators of insect pests, particularly in forest and agroecosystems. Within Braconidae, wasps in the tribe Euphorini (Euphorinae) attack economically damaging plant bugs (Miridae) that are major pests of field and vegetable crops. However, the evolutionary relationships of this tribe have been historically problematic.

Background: The tribe Centistini includes three genera, Allurus, Centistes and Centistoides (Stigenberg et al. 2015). They are solitary endoparasitoids of adults and final instar larvae of beetles from the family Curculionidae (Jackson 1920, Aeschlimann 1980, Tobias 1986).
