Summary: This study inferred the phylogenetic tree of Kalotermitidae using mitochondrial genomes and revealed that early-diverging kalotermitid lineages had disjunctions predating the breakup of Gondwana. Most of the disjunctions between biogeographic realms occurred in the last 50 million years, indicating that transoceanic and human-mediated dispersals have driven the global distribution of Kalotermitidae. The study also suggests that early-diverging kalotermitids had the ability to forage among multiple wood pieces.

Summary: World trade has led to an increased risk of introducing non-indigenous pests. However, the lack of historical data on pest introductions poses a challenge. By collecting and compiling data from various sources, a comprehensive dataset on pest introductions in the EU has been created, providing a basis for understanding the factors associated with the likelihood of pest introductions.

Summary: Termites, social cockroaches distributed in warm temperate and tropical ecosystems, have a distribution shaped by vicariance and overseas dispersal. Through studying the historical biogeography of three early diverging termite families, it was found that their distribution was influenced by over-water dispersals and land bridges.

Summary: This study analyzed the records of intercepted pests from wood packaging materials from 2003 to 2016 in the China Port Information Network (CPIN) database. It was found that the number of interceptions increased annually, with most pests originating from Asia, particularly xylophagous insects from Southeast Asian countries and nematodes from Korea, Australia, Mexico, and other countries. The findings suggest the need for continued improvement of inspection procedures and international trade policies to prevent the spread of exotic pests.

Summary: In Italy, significant hybridization is occurring between the invasive North American fungal plant pathogen Heterobasidion irregulare and its Eurasian sister species H. annosum. The study sequenced and compared the whole genomes of nine natural hybrids with their parental species, revealing genetic relationships and levels of admixture. Findings suggest that hybridization can lead to adaptive introgression, increasing fitness in certain genotypes.

Summary: Habitat loss, fragmentation, and invasive species are the main causes of biodiversity loss. In the Atlantic Forest, the native species Callithrix aurita is threatened by habitat modification and the invasion of the non-native species Callithrix jacchus. Landscape variables and the distance to roads influence the presence of both species, with C. aurita occurring in higher altitudes and less urbanized areas, while C. jacchus is found in urbanized areas, mostly in non-mountainous terrain. Conservation measures should focus on regions where C. aurita is more present and the negative influence of C. jacchus is still limited.

Summary: Edible insects as a novel food source are being researched for their potential use in traditional products, with enriched muffins showing increased protein content, antioxidant capacity, and lower glycemic index. Consumers have positively accepted the enriched muffins, indicating a potential market for insect-fortified food products. Further studies are needed to explore the effects of insect addition on the biological activity of food in vivo.

Summary: Tropical cyclones can transport birds and insects from tropical regions to areas along their paths. A polarimetric radar was used to observe biological scatterers, likely birds and insects, in the eye of super Typhoon Lekima before landfall. The characteristics of these scatterers included low reflectivity factor, low correlation coefficient, large differential reflectivity, and widely distributed differential phase. This study's findings help us understand how typhoons can transport biological matter and affect ecosystems.

Summary: The study found that some insular vertebrates are threatened by IAS, with threatened amphibians hosting 50% of functional richness and birds hosting up to 29%. Groups threatened by IAS have higher functional richness compared to those threatened by other threats. Birds, lizards, and mammals are more likely to be terrestrial foragers, while amphibians are more likely to have larval development.

Summary: Kings and queens play a key role in maintaining high aggression levels of termite workers and soldiers toward non-nestmate intruders, with colonies lacking royalty showing lower aggression levels. This suggests that social conditions, including royal presence, can influence intercolonial interactions.

Summary: The white-bellied planthopper, S. pacificus, is an important pest of crops and has recently appeared in Asia. This study reports the first record of S. pacificus in mainland Japan and confirms its identification through morphological and molecular analysis. Although crop damage in temperate regions has not been reported yet, monitoring of crops in Asia, including temperate regions, should be conducted due to the wide range of host plants and potential for future expansion of this species.

Summary: In this study, a transcriptomic database was generated for the yellow crazy ant to identify RNA viruses and characterize their genomes. Multiple virus species were discovered, including the polycipivirus AgrV-3, which showed high genetic diversity and evolved following the quasispecies model. The viral pathogen hotspot of the ant was found in Southeast Asia, consistent with its native range, and multiple virus species were prevalent in field colonies, possibly linked to the ant's social organization.

Summary: There is a unique symbiotic relationship between subterranean termites and the sclerotium-forming fungus Athelia termitophila, where the fungus forms termite-egg-mimicking sclerotia called 'termite balls'. The research shows that Athelia termitophila is competitive against other wood-decay fungi at low temperatures. Further studies are needed to understand this relationship.

Summary: Caste-based reproductive division of labour in social insects is based on asymmetries in resource allocation within colonies. Kings and queens consume limited resources for reproduction, while non-reproductive castes help reproductive castes. Studying the regulation of resource allocation is crucial for understanding insect sociality, although the molecular background is poorly understood.

Summary: Termites play an important role in the natural environment as decomposers. To establish a stable termite breeding method, it is necessary to develop a standard medium for each termite species. In this study, a standard medium called brown-rotted pinewood mixed cellulose (BPC) medium was developed for culturing the termite Reticulitermes speratus.

Summary: Termites are both decomposers in ecosystems and pests of wooden buildings. Researchers have developed two media for rearing American termite species, using winged elm and loblolly pine. The results show that these media can be used for colony foundation and rearing workers, and the BPC medium is more suitable for R. virginicus workers. These new media will contribute to the maintenance of termite colonies in the laboratory.

Summary: Society in eusocial insects is based on reproductive division of labor, with sterile members providing special food to kings and queens through discriminative trophallaxis. The composition of the special food differs between kings and queens. Analysis of food contents and digestive system structures reveals specific compounds and differences in digestive division of labor among castes. These findings shed light on the extraordinary reproduction and longevity of royals in eusocial insects.

Summary: This study reports the first discovery of the cedar bark aphid in Japan, which is native to the East Mediterranean region and has been introduced to multiple countries. The researchers found that the Japanese populations of this aphid species have the same mitochondrial COI sequences as populations in the USA, Canada, and some European countries, and they also carry the same strain of Wolbachia. Additionally, it was observed that these aphids are capable of overwintering in Japan.
