The number of social hymenoptera have decreased due to accelerated urbanization in Seoul, Korea, during the 1970s–1990s. However, recent changes in environmental conditions have brought distinct re‐growth of their colonies. In this study, we analyzed the re‐colonization trend of social hymenoptera in Seoul with moving‐out reports submitted to 119 rescue services from 2000 to 2009. A total of 14 253 social hymenoptera findings and treatment cases were reported during that time, and the reported numbers increased continuously every year. Among them, 87% of the cases were related to social wasps and 13% were for honeybees. Social wasps peaked from July to September, when the colonies matured, whereas honeybees peaked from April to July when colonies divided. As observed by geographical information system (GIS), moving‐out cases formed hotspots in low‐story buildings around green areas such as nearby forests or city green parks in Eunpyeong‐gu and Gwanak‐gu in Seoul. Among the social wasps, the most frequent species that caused a nuisance and direct stinging was Polistes rothneyi koreanus, the majority of which nested under eaves (63%). Among the honeybees, Apis mellifera was a nuisance while attaching to buildings and walls in the city (60%) during hive splitting. We present herein the situation of the return of social hymenoptera to Seoul and discuss the possible reasons for the recent increase in social wasps in urban areas, including enlarging the green space in urban areas and stable nesting places, which benefited colony development due to the relatively higher urban temperature and the few natural predators and parasitoids.

Introduction of exotic species poses a tremendous challenge to the preservation of original biodiversity and productivity in natural ecosystems. The yellow‐legged Asian hornet Vespa velutina nigrithorax, which is native to tropical/subtropical areas in Indo‐China, was identified in 2003 for the first time in South Korea and has established itself in a short period of time. Population genetic study of invasive species may provide exceptional opportunities to test evolutionary theory as well as patterns of colonization from the beginning of the process. Here, the genetic variability of this invasive hornet was examined using seven microsatellites to estimate the propagule pressure and to expect the spreading pathway of this invasive hornet across its range. Overall, there was a significant loss of genetic diversity in its invaded ranges compared to its native range, suggesting that this invasive hornet was introduced via a very small number of propagules. Our results also support that this invasive hornet has experienced a severe bottleneck, as a large reduction was mainly observed in the number of alleles but not in heterozygosity. No significant genetic structuring among populations was found. This study provides baseline information about the current demographic status of the invaded populations, which will help governing agencies prevent further invasions and manage native ecosystems.
중부산 지역의 도시화와 왕바다리 Polistes rothneyi koreanus (Vecht) (말벌과: 쌍살벌아과)의 우점분포의 관계

부산광역시에서 가장 도시화된 중부산 지역에서 1996년에서 2005년 사이에 왕바다리 Polistes rothneyi korenus (Vecht)의 분포 영역과 경향을 조사하였다. 쌍살벌 종류 중에서 왕바다리는 중부산 전역에 우점적 분포를 하지만 숲의 중심에서 출현빈도가 감소하는 것으로 나타났다. 반면, 별쌍살벌 P. snelleni, 두점박이쌍살벌 P. chinensis, 어리별쌍살벌 P. nipponensis는 도시화 된 지역보다는 대체로 숲 중심으로 기록되며 극히 제한된 분포를 보였다. 따라서 왕바다리는 도시화된 지역에서 녹지와 도시화 공간 모두에 광범위하게 서식하는 중부산지역의 우점적인 쌍살벌 종으로 나타났다. Distribution tendency of Polistes rotnenyi koreanus (Vecht) was investigated in the urbanized central Busan areas between 1996 and 2005. P. rothenyi was recorded from most investigated sites although the species was distinctly declined at the forest-centre. The other polispine wasps P. snelleni, P. chinensis and P. nipponensis seem to limit their nesting sites at more natural areas than urbanized areas. P. rothneyi was likely to be the most predominant species widely both in urban and natural areas in the urbanized central Busan areas.

The composition of the Martes flavigula diet has been extensively studied, but little is known about its insect component. This study characterized the insect diet and insect nest materials in the feces of M. flavigula. A total of 952 fecal samples were collected in Jirisan National Park from January 2009 to November 2011, and 1379 species or taxonomic groups were identified. M. flavigula fed on insects (8.7%) and bee wax (5.0%), which comprised 2.9% and 4.4% of the dry weight of M. flavigula feces, respectively. A total of 12 insect species belonging to 8 families in 3 orders were identified. The most frequently found insects were Hymenoptera (frequency of occurrence, FO, 89.1), including Vespa simillima simillima (FO, 37.3) and Vespula koreensis koreensis (FO, 20.0). The Vespidae constituted the majority of the insect diet in autumn when the diversity of marten’s prey was strongly reduced, probably because the numbers of social insects were sufficient for M. flavigula. In addition, the data suggest that M. flavigula attacks the nests of social wasps in late autumn when males do not have a venomous sting and new queens are less aggressive than workers. Bee wax appeared in all seasons and the highest rate was from spring to early summer. However, the remains of honeybees were not found in feces; thus, M. flavigula presumably eats honey but not honeybees.
영도산 생물다양성의 분류학적 측정과 도시생태학적 평가 Ⅱ. 벌목
최문보,문태영 고신대학교보건과학연구소 2001 보건과학연구소보 Vol.11 No.-
부산 영도 봉래산의 생태계를 이해하기 위한 일환으로 벌목에 대해 조사를 하였다. 봉래산에서 총 13과 101속 123종이 조사되었는데 그 중 점박이 땅벌이 13.14%를 나타내어 우점종을 나타내었고 그 뒤로 말벌, 장수말벌, 좀말벌, 곰개미가 따랐다. 따라서 봉래산에 서식하는 벌목 중에서 말벌과에 속한 종들이 우점군을 차지하고 있는 것으로 나타났다. 이는 봉래산의 식생이 빈약하기 때문에 식생의 영향을 많이 받는 맵시벌과나 꿀벌과에 비해 말벌과가 적응도가 높은 것으로 보인다. 그래서 봉래산에 있는 벌목의 종다양성 확보를 위해서는 봉래산 실정에 맞는 생태적인 질의 향상을 모색해 알맞은 장소에서 복원을 해야 할 것이다. Insects may provide the important clues related to human death. The insects are a good substitute to traditional materials for forensic analysis to estimate postmortem intervals and location of bodies. In case of decayed or dried remains, it is difficult to carry out precise analysis in traditional materials as muscles or internal organs decayed, while insects feeding on cadavers may be appropriate for the analysis. Various toxins and drugs were discussed for their impact on insects and their fates in insects in forensic aspects of view.
