  • Bemisia tabaci (Hemiptera: Aleyrodidae) is one of the major insect pests causing economic damages to over 900 different crops in the world. Especially, B. tabaci JpL (L. japonica) is known as a species living only in Japan and Korea so far, and mainly in Lonicera japonica and specific plant species. This study was conducted to investigate the occurrence and spread of B. tabaci JpL on Jeju Island in 2019. Of the total 25 areas surveyed, 1,003 individuals of B. tabaci JpL adults were collected from 24 L. japonica and one Conyza sumatrensis. All populations identified belonged to the JpL species. The result of this study showed that the population of B. tabaci JpL has increased at very high speeds to date compared to the previous reports in Korea.

  • This research is to collect, classify and identify the insects boring tunnels into wood or damaging wooden frame structure. Intensive insect collections have been carried at the historical local schools annexed to the confucian shrine from March to September 2001. Ten species of Coleoptera, 15 species of Hymenoptera, 6 species of Hemiptera, 4 species of Ditera and 1 species of Demaptera were recorded. Most species of Coleoptera and Hymenoptera have the manducatory apparatus in the mouth-part that cause severe damage in wood, and showed the highest population among the genera recorded. Further research should be considered on the identification of wood demage insects at the species level among present collection and their mechanism of wood demage in the wood.

  • This study was carried out to know the insect fauna of turf grass area in forest. In Korea, graves and public cemetery in mountain areas are usually covered by turf grass which were mainly examined. There were 86 species belonging to 77 genera of 39 families in 11 orders. Among them, site 3 had highest occurrence (38%), second was site 2 (36%) and in the last place was site 1 (26%). Hemiptera revealed best species composition (29.1%) and came Coleoptera (19.8%), Orthoptera (15.1%), Lepidoptera (12.8%) and Odonata (5.8%) etc. The reason why Hemiptera and Orthoptera are mainly found in these areas is because they usually feed on short plants that grow in there. Taxonomic species composition, occurrence ratio by site and species and comparison analysis were provided.

  • During 15 months from 13. Jul. 2018 to 29. Oct. 2019, we monitored on the hitchhiker insect pests from a total of 306 foreign vessels entering into Korea. As the results, a total of 805 samples of the hitchhiker insects were collected using simply collecting method by hands and identified as 379 species of 78 families under 12 orders on the basis of integrative species identification. Among them, 42 species (67 individuals) of 21 families under seven orders were detected as not-distributed species in South Korea. Of the 42 not-distributed species, seven species were multiply detected in 2018 and 2019, and two species, Erthesina fullo (Pentatomidae, Hemiptera) and Tessaratoma papilosa (Tessaratomidae, Hemiptera) were discovered as regulated insect pest. Therefore, we reported on the 42 not-distributed species in South Korea with the data sheets for the establishment of a monitoring plan on the not-distributed species and the risk assessments on invasive or invasive likelihood species.

  • This study investigated the distribution and overwintering of Phanuromyia ricaniae(Hemiptera: Platygastroidea), an egg parasitoid of Ricania sublimata(Hemiptera: Ricaniidea), in order to acquire basic information for biological control. P. ricaniae is distributed in some areas of Gyeonggi, Chungcheong, Jeolla, and Gyeongnam provinces. P. ricaniae is highly prevalent in the southwestern plains, with a tendency to expand to the northeastern area of Korea in line with the dispersal of R. sublimata. The parasitism of P. ricaniae was 1-8% in the field, and the highest in Suncheon, followed by Gurye and Gongju. P. ricaniae overwintered inside the eggs of R. sublimata from September to June of the next year, and transformed into adults in June. The rapid cold-hardiness of P. ricaniae was the highest in the egg state.
