Summary
Researchers identified eight fungal species in South Korea that live inside ambrosia beetles in a special partnership where the fungi feed the beetles. These fungi had never been documented in Korea before. The study examined beetles from nine forest locations and found these fungi species living with 15 different types of ambrosia beetles, establishing which fungi work with which beetles.
Background
Ambrosia fungi maintain symbiotic relationships with ambrosia beetles, serving as the sole food source for beetle larvae and adults. Over 50 ambrosia beetle species reside in South Korea, yet their fungal partners remain largely undocumented. Only one ambrosia fungal symbiont species had been previously reported in Korea despite the ecological and economic significance of these relationships.
Objective
To conduct an extensive survey of fungal symbionts associated with ambrosia beetles dwelling in South Korea and identify previously unrecorded fungal species. This first comprehensive study aims to reveal the fungal-beetle interactions and provide taxonomic descriptions of newly documented species.
Results
Eight fungal species previously unrecorded in Korea were identified from 15 ambrosia beetle species, yielding 67 isolates from 56 beetle samples. Three Ambrosiella species, one Leptographium, two Raffaelea, one Sporothrix, and one Irpex subulatus were identified with detailed taxonomic descriptions provided for each species.
Conclusion
This study significantly expands knowledge of ambrosia fungal diversity in South Korea and documents specific associations between fungal species and their beetle hosts. The findings establish a foundation for understanding these important symbiotic relationships and their potential ecological impacts in Korean forests.
