To find out the effect of global warming (long-term air temperature change) on insect population, we developed long-term monitoring program for Scotinophara lurida (Burmeister) and Paromius exiguus (Distant). The monitoring programs for these target insects are consisted of two main areas; Field monitoring and modelling of long-term population change. For the field monitoring, we conduct the survey of target insects on host plants, light trap monitoring, overwintering habitat sampling, and the monitoring of daily air temperature change. The field monitorings has been conducted for 10 and 4 years for S. lurida and P. exiguus, respectively. For the modelling of long-term population change, we have already developed basic phenology models for both insects. The developed phenology models are validated using yearly field sampling data and air temperature data. Environmental factors which could affect the populations of target insects are studied in laboratory to find out the magnitude of the effects. Based on the basic phenology models and parameters for newly found factors, long term population dynamics models for both insects will be developed.

This study was conducted to identify the seasonal occurrence patterns of peach pyralid moth, Dichocroscis punctiferalis (Guenee), and persimmon fruit moth, Satthmopoda masinissa Meyrick, in persimmon orchards in four different regions, Ulsan and Jinyeong in Gyeongsangbuk-do, and Naju and Yeongam in Jeollanam-do. Three pheromone traps (Delta trap, GreeAgro Tech) for each moth species were installed at each site and checked with 1 week intervals. Peach pyralid moth and persimmon fruit moth occurred in all four study sites. Two moth species exhibited two distinctive peaks, but there were some time differences in the peak among sites. Peach pyralid moth first occurred in late May to early June in Ulsan, Jinyeong and Naju but occurred in late July in Yeongam. Overall, the first peak appeared in mid- to late June but the time of the second peak varied widely among sites. Persimmon fruit moth first occurred in early to mid-June in Ulsan, Jinyeong and Naju but occurred in mid-May in Yeongam. The first peak appeared in mid- to late June in Ulsan, Jinyeong and Naju but it appeared in late May in Yeongam. The time of the second peak was around late August in the study sites except Ulsan where the second peak time was in late September.

This study was conducted to explore if the ground beetle (Coleoptera: Carabidae) can be used as an indicator classifying habitat types. Thirteen land use types were selected as survey sites in Jeonju. Ground beetles were collected by 3 pitfall traps (15 cm diameter) for each site from June 20 to September 22, 2008. Pitfall traps were replaced at one month interval. Total 919 ground beetles of 31 species belonging to 17 genera were collected. Land use types were classified and ordinated by two-way indicator species analysis and detrended correspondence analysis. Land use types were classified and ordinated into two major groups, forest and non-forest, by Synuchus nitidus and Dolichus halensis. Two major groups were subdivided into 4 end groups; forest, riverside, upland and other sites. Other sites group including 4 sites; levee, public garden, outfield and manufacturing area were not coincided with land use types. Nevertheless, ground beetles appear to be used as indicators of habitat types.
