We investigated the diversity and occurrence of wood wasps in Lithuania and determined communities of associated fungi. Trapping of wood wasps resulted in three different species, including , , and . Fungal culturing from adult females of mainly resulted in fungi from the genera and . High-throughput sequencing of ITS2 rDNA resulted in 59,797 high-quality fungal sequences, representing 127 fungal OTUs. There were 93 fungal OTUs detected in , 66 in , and 10 in . The most common fungi were (63.1% of all fungal sequences), (14.9%), (7.8%), sp. 2261_4 (5.0%), and (2.1%). Among these, only was found in all three insect species with the highest relative abundance in (15.2%), followed by (7.7%), and the lowest in (0.3%) ( < 0.0003). Correspondence analysis of fungal communities showed a distant placement of different species of wood wasps, indicating that fungal communities in each of these were largely different. In conclusion, the study showed that the economically important tree pathogen was among the most common fungal OTUs vectored by siricid wood wasps.

The evolution of convergent phenotypes is of major interest in biology because of their omnipresence and ability to inform the study of evolutionary novelty and constraint. Convergent phenotypes can be combinations of traits that evolve concertedly, called syndromes, and these can be shaped by a common environmental pressure. Parasitoid wasps which use a wide variety of arthropod hosts have also repeatedly and convergently switched host use across their evolutionary history.

An essential adaptive strategy in insects is the evolution of olfactory receptors (ORs) to recognize important volatile environmental chemical cues. Our model species, Ceratosolen fusciceps, a specialist wasp pollinator of Ficus racemosa, likely possesses an OR repertoire that allows it to distinguish fig-specific volatiles in highly variable environments. Using a newly assembled genome-guided transcriptome, we annotated 63 ORs in the species and reconstructed the phylogeny of Ceratosolen ORs in conjunction with other hymenopteran species.

Objective: wasps are important biocontrol agents of a class of wood borers. Bacterial symbionts influence the ecology and biology of their hosts in a variety of ways, including the formation of life-long beneficial or detrimental parasitic infections. However, only a few studies have explored the species and content of the symbionts in the species.

Article Synopsis
- Insects have advanced sensory systems crucial for survival activities like feeding and reproduction, with parasitoid wasps using specialized sensors to locate hidden hosts.
- Researchers have discovered two new species of fossil wasps from Cretaceous amber, which show evolutionary traits linking them to modern wasp families.
- These wasps exhibit unique physical features, including a distinct "bottle brush" set of sensors, suggesting they had specialized adaptations for detecting insect larvae hidden in wood for laying their eggs.
