The study conducted to understand the annual phenology of hemipteran insect pests including Halyomorpha halys, Nezara antennata, Plautia stali, and Riptortus pedestris in Jeju, Korea, 2017 and 2018. We investigated the population density of them at three locations for two years. The commercial and fish trap were used for monitoring. We compare the seasonal occurrence among species and sampling locations. The repeated measured ANOVA was used to explain the difference of seasonal occurrence among locations and sampling time. There was difference the first adult catch and the peak occurrence of species among sampling sites.

The brown marmorated stinkbug, Halyomorpha halys, is an invasive insect pest in North America and Europe that attacks crop species and causes substantial economic damage. To evaluate the genetic diversities and distributions of different H. halys populations in East Asia, North America, and Europe, COI sequences obtained from 79 new specimens from Korea and 10 from the USA were compared with 725 existing COI sequences. In total, 45 haplotypes were detected in populations from 10 countries. Sixteen haplotypes from Korea (H34–.H49) and 2 from the USA (H50 and H51) were novel. Korean populations exhibited the 2nd highest diversity among the 10 countries, with only Greece exhibiting higher diversity. Haplotype H22 was prominent in Korea, H1 was prominent in China, Greece, Hungary, Italy, Canada, and USA, and H3 was prominent in France and Switzerland. Of the 18 haplotypes found in Korea, 1 was shared with China (H2) and 1 with Greece (H22). Haplotype diversity patterns showed that Korean populations were genetically distinct from populations in China, Europe, and North America. This suggested that populations in Europe and North America arose through multiple invasions from China and that (with the exception of Greece), Korean populations did not spread to other countries. This study represents a comprehensive analysis of H. halys populations in Korea and places these populations in a global context that includes other native populations in East Asia and invasive populations in Europe and North America.

상용집합페로몬 트랩을 이용하여 썩덩나무노린재, 갈색날개노린재, 풀색노린재의 연중 포획 밀도 변동을 3개지역(김제, 장수, 사천) 사과 및 단감 과원 주변에서 조사하였다. 썩덩나무노린재의 경우 김제, 장수지역의 사과원주변에서는 8월 중순, 9월 중순, 10월 중순에 포획 최성기가 있었으며, 사천지역 단감원 주변에서는 9월상순과10월 상순에 포획 최성기가 관찰되었다. 갈색날개노린재의 경우 3개 지역 모두에서 7월 상순과 9월 상순 2번의낮은 포획 최성기가 있었으며, 풀색노린재의 경우 3개 지역 모두에서 10월 상순에 1번 포획 최성기가 관찰되었다.한편 썩덩나무노린재의 천적인 노린재기생파리에 기생된 썩덩나무노린재 성충의 포획 시기를 보면 사천지역의단감원 주변에서는 6월 하순과 8월 하순에, 김제와 장수지역의 사과원 주변에서는 8월 중순부터 9월 상순까지포획 최성기가 있었다.

Halyomorpha halys(Stål, 1855) (Hemiptera: Pentatomidae), also known as Brown Marmorated Stink Bug (BMSB), is a recent invasive pest in America and Europe. It originated from East Asia such as Korea, Japan, China, and Taiwan. Genus Trissolcus (Hymenoptera: Scelionidae) which is regarded as important species for biological control of H. halys, was described 6 species previously in Korea. But biology and taxonomic character of this genus is poorly known in Korea. Herein, we report two species from Korea, T. japonicus Ashmead, 1904 and T. plautiae Watanabe, 1954. We have investigated the morphological characters and COI sequence, and conducted an experiment about parasitic preference on BMSB's egg. Morphological key and picture of two species, and result of sequence investigation and experiment will be presented.
