이 연구에서 채집된 아메리카동애등에의 성충은 원산지의 성충과 그 크기가 비슷했다. 체형에서 가장 큰 차이점을 보이는 부분은 더듬이 바깥쪽 (antenna 2) 길이이며, 그 다음으로는 머리넓이 (head width), 복부넓이 (abdomen width) 등의 순으로 나타났다. 이 연구결과는 유기물 분해와 분변토 생산의 우수개체를 선발하는데 기초자료가 될 것이다. 국내 51개 조사지역 중, 22개 지역에서 아메리카동애등에가 출현했으며 위경도 및 고도 등 지리적 특성보다는 유기물의 존재에 더 영향을 받는 것으로 생각된다. 이 곤충의 발생현황은 유기성 폐자원의 선순환 구조를 파악할 수 있는 지표로 사용될 수 있을 것이다.

The invasive black soldier fly, Hermetia illucens, has been paid much attention as an excellent organic matter decomposer. We conducted the nationwide survey and the population genetic study using a mitochondrial cytochrome C oxidase 1 gene to understand its genetic diversity and distribution pattern in Korea. The results show that it has successfully settled down in South Korea and there are only 10 haplotypes and the populations of the insect are highly differentiated. The results indicate that only few maternal lineages were introduced and their dispersal was restrained due to their short distance flying tendency since their introduction.

The black soldier fly (Hermetia illucens) (Diptera: Stratiomyidae) is an invasive species that is thought to be endemic in Korea. The insect has been paid much attention thanks to its ability to decompose organic wastes. We collected the insect nation-wide in 2006 and 2010 to investigate its genetic structure based on the mitochondrial cytochrome oxidase 1 (mt CO1) haplotype. The results show that during the time period the insect seems to lose some rare haplotypes. We conclude that the insect may have experienced genetic bottleneck while its settlement in Korea. In our presentation, we show its updated haplotype network and genetic differentiation and propose potential explanations.

Taxonomic resolution of the Nosema/Vairimorpah clade has been augmented with DNA sequences of the small subunit (SSU) and large subunit (LSU) ribosomal RNA (rRNA) and the arrangement of SSU and LSU. Based on the two characteristics, the clade is largely divided into two, i.e. 'true' Nosema sub-group and 'non-true' Nosema sub-group within the clade. Our study shows that a novel Nosema species isolated from Pieris rapae has mixed characteristics of the 'true' and non 'true' Nosema sub-group based on the topology of SSU and LSU sequences, and rRNA of the isolate is normally organized. Additionally, the length of ITS can be a diagnostic tool to distinguish 'true' Nosema from non 'true' Nosema in the Nosema/Vairimorpha clade based on its nucleotide length as reported before. To our knowledge, this is the first report of recombination event in the Nosema/Vairimorpha clade.
