The Korea National Arboretum (KNA) of the Korea Forest Service (KFS), in collaboration with a research team led by Professor Kang Il-goo of Kyungpook National University, has discovered and formally described a new species, Doggerella chasanica.
The Braconidae is one of the most diverse groups of wasps. Of the more than 4,200 bee and wasp species known in Korea, approximately 1,140 belong to the Braconidae. These parasitoid wasps typically parasitize the larvae of moths and beetles and exhibit considerable diversity in species composition and host range.
The newly identified species was discovered during a re-examination of specimens collected on Jeju Island in 2019 and preserved at the KNA's Korea National Herbarium.
The species parasitizes third-instar larvae of Monochamus alternatus, occurring between mid-June and mid-July, which coincides with the adult emergence period of its host.
The average parasitism rate of Doggerella chasanica on Monochamus alternatus is about 4.2%. Notably, this study is the first to scientifically document the parasitic relationship between this braconid wasp and its host larvae.
The findings were published in the Journal of Hymenoptera Research (2025, Vol. 98, pp. 545–558), an international scientific journal specializing in Hymenoptera.
A researcher from the KNA's Forest Biodiversity Research Division noted, "Jeju Island has an insect fauna that differs somewhat from that of mainland Korea, and this braconid wasp appears to be one such example. The study reveals a previously undocumented host–parasitoid relationship that has not yet been observed on the mainland."
