Moths were caught by using two 22W UV black light traps per treatment during May, June, August and September in 2007 from our study sites. Our study areas of the Korea Long Term Ecological Research (KLTER) sites were Mt. Nam with two plant communities (Quercus mongolica, Pinus densiflora), Mt. Jiri with three plant communities (Q. mongolica, P. densiflora, Abies koreana), Mt. Wolak with three plant communities (Q. mongolica, P. densiflora, Q. variabilis), and Mt. Jumbong with t재 plant communities (Q. mongolica, P. densiflora). The purpose of this study was to compare the species diversity of major plant feeders, Lepidopteran species (moths) at each forest type of the regional KLTER sites. Overall, the total numbers of moth species we’ve collected from the all KLTER sites in 2007 were 670 species. For the three plant communities, Mt.Jiri (11 family, 259 species, 2372 individuals) was the highest site and Mt. Wolak (7 family, 401 species, 2243 individuals) was the next highest. For the two plant communities, Mt. Jumbong (14 family, 166 species, 1750 individuals) was highest and Mt Nam (4 family, 21 species, 142 individuals) was very few. The ordination analyses, Nonmetric multidimensional scaling (NMS) and cluster analysis, showed distinct clusters separating the assemblages of moth found at each site and each plant community of the KLTER sites (P<0.05 from MRPP). Therefore, we suggest that our sustainable monitoring will verify the distinct cluster with the forest type at each site with many replications.

We assessed the environmental risk of herbicide resistant transgenic rice (Protox) on non-target herbivore, grasshoppers (Oxya japonica japonica Thunberg). We conducted life-history experiments of grasshoppers with measuring their body weight, body length, eating amount, and feces amount between non-transgenic rice (nTR; Dongjin rice) and transgenic rice (TR; Protox rice) under laboratory conditions (Temp. 25Ð, R.H. 50-70%, Photoperiod L16:D8) in 2007. The growth of grasshoppers appeared to increase at each measuring date. We also compared the growth rate of grasshoppers between nTR and TR to examine the transgenic impact on the herbivore and we found there was no statistically signifi cant difference between the two plant types (P>0.05). We found that body weight and body length for grasshoppers were highly correlated at each of the two types of plants, nTR (0.962) and TR (0.960). The correlation of eating amount and feces amount of grasshoppers were higher nTR (0.830) than TR (0.782). The energy effi ciency of the grasshopper was not a signifi cant between nTR and TR (P> 0.05). But the molt timing of the grasshoppers for TR difference was faster than for nTR. Conclusively life-history of the grasshoppers but molt timing was not a signifi cant difference between nTR and TR. Therefore, we could conclude there was not any environment risk on herbivore from our result.

Hoonbok Yi,Sathiyaraj Srinivasan,Myung Kyum Kim 한국미생물학회 2010 The journal of microbiology Vol.48 No.1
The study isolated a Gram-negative, rod-shaped, non-motile bacterium from the soil of a ginseng field in Daejeon, South Korea and characterized it to determine its taxonomic position. Phylogenetic analysis, based on the 16S rRNA gene sequence, revealed that strain MK06T belongs to the family Xanthomonadacea, and showed the highest degree of sequence similarity to Stenotrophomonas rhizophila e-p10T (98.6%), Xanthomonas campestris LMG 568T (98.0%), Stenotrophomonas maltophilia ATCC 1d3637T (97.3%), and Stenotrophomonas humi R-32729T (96.9%). Chemotaxonomic data revealed that strain MK06T possesses ubiquinone Q-8 as the predominant respiratory lipoquinone, which is common in the genus Stenotrophomonas, and that the predominant fatty acids were 15:0 iso (41.1%), 15:0 anteiso (12.6%), and 17:1 iso ω9c (8.6%). The results of physiological and biochemical tests clearly demonstrated that strain MK06T represents a distinct species and supported its affiliation with the genus Stenotrophomonas. Based on these data, MK06T (KCTC, 22893T; JCM,16536T; KEMB, 9004-002T) should be classified as the type strain for a novel species, for which we propose the name Stenotrophomonas panacihumi sp. nov.
The Development of the Very Efficient Mosquito Traps, Mos-hole and DMS
Hoonbok Yi,Hyun-jung Kim,Jong-woo Nam,Jieun Seong,Long-jin Jung,Dong-sik Ryu,Jae-Seung Yu 한국응용곤충학회 2012 한국응용곤충학회 학술대회논문집 Vol.2012 No.05
We developed two kinds of selective mosquito traps. The first selective mosquito trap called Mos-hole was developed with emitting carbon dioxide. The principle was that CO2 gas was obtained from burning liquid naphtha. The process principle was very unique that some heat and moisture which cannot be obtained by using dry ice could be generated additionally. It is the main cause to bring more mosquitoes. The trap is consisted of the acidic and CO2-baited suction system. CO2 was so powerful mosquito attractant gas, and the color and shape of a suction trap was also very important factors for improving the mosquito capturing efficiency. The trap burned naphtha in a rate of 1.3g/hr~3.0g/hr (CO2:50ml/min-110ml/min) and the efficiency of the trap was higher at the burning rate with the high number of female mosquitoes. The second mosquito trap called DMS (Digital Mosquito Monitoring System) is developed for reporting the number of captured mosquito automatically every day. This automatic reporting device called DMS uses CO2 gas as a mosquito attractant and it has a IR array sensor for counting mosquito. We established a sensor network with several DMSs and one server. The server collected the data of each DMS through Internet or CDMA RF communication system. This data were analyzed in the GIS pest prevention information system and were sometimes used as a reference for the next pest control activities. The DMS systems emit CO2 about 300cc/min. CO2 was very effective for attracting mosquito. DMS systems were very effective to count the number of mosquitoes at the certain areas. By using two kinds of mosquito traps together, we could determine the mosquito population size increase and decrease at certain areas

Hoonbok Yi,Jae-seung Yu,Hyunjung Kim,Wookgyo Lee,YoungRan Ju,Mi-Yeoun Park,E-hyun Shin 한국응용곤충학회 2015 한국응용곤충학회 학술대회논문집 Vol.2015 No.10
We developed the smart mosquito counter device (height 1080 mm x width 560 mm x diameter 320 mm, 220V 60Hz 30 W), which can attract the blood sucking female mosquitoes by emitting CO2 gas (300ml/min), can count the number of the captured mosquitoes by an infra-red beam area sensor, can identify the some mosquito species by analyzing mosquito image patterns using RGB (Red, Green, and Blue), and can send the captured mosquitoes’ number and pictures through the CDMA module at the real time. We operated the smart mosquito device and we could know when any mosquito peak time was in a day as well as what the mosquito species are and the captured mosquito numbers are. We found that the accuracy of the smart device was about over 95% compared the real mosquito data including numbers and images and transmitted data by CDMA. Because we can know the mosquito occurrence peak times, locations, and mosquito species by this device, we can efficiently control mosquitoes at the right time, and we can alert the public for any mosquito-born diseases based on the mosquito occurrence data. We can improve the quality of mosquito vector control with the functions of this device and we will develop the smart device to identify more mosquito species.

We are currently developing the smart mosquito counter device (height 1080mm × width 560mm × diameter 320mm, 220V 60Hz 30W), which can attract the blood sucking female mosquitoes by emitting CO2 gas (300ml/min), can count the number of the captured mosquitoes by an infra-red beam area sensor, and can send the captured mosquitoes’ number through the CDMA module at real time. We operated the 8 – 16 devices with mosquito sensor networks and a server at the Youngdeungpo-gu areas in Seoul city of south Korea for three years (2011-2013) and we could efficiently control mosquitoes at the high mosquito density area based on the mosquito sensor’s data. We found that the accuracy of the device was about over 93% compared the real mosquito data and transmitted data by CDMA. We also found the water reservoir areas to control floods in Seoul metro city had relatively higher mosquito density than other normal areas, because those flat water areas were preferred by mosquitoes. Because our pest control office knew the mosquito occurrence peak times and areas from mosquito data transmitted by the mosquito sensor devices, we efficiently controlled mosquito larva and adults at the right time. We could accomplish very systematic mosquito control policy and we had the high credibility with the results. Based on the mosquito occurrence data, we selectively and scientifically controlled mosquitoes. Therefore, we reduced pesticide usage and saved annually pesticide expenses up to 2/3. Conclusively, if there is no mosquito, we don’t have to control mosquitoes.

To establish quantitative methods for ecological risk assessment, we assessed the impacts of transgenic watermelon rootstock (Citrullus lanatus (Twinser) cv. Gongdae) that was resistant to cucumber green mottle mosaic virus. The diversity of soil bacteria and fungi was monitored from May to July of 2005. Terminal restriction fragment length polymorphism (T-RFLP) was used with 16S ribosomal RNA (rRNA) coding genes for bacterial communities and with internal transcribed spacer (ITS) regions of rRNA coding genes for fungal communities. Multivariate analysis of variance (MANOVA) on the principal component analysis (PCA) scores of T-RF profiles detected no significant difference between microbial communities with transgenic or non-transgenic watermelon. Likewise, the results of our multi-response permutation procedure (MRPP) tests on non-metric multidimensional scaling (NMS) showed no significant difference between plant types. However, both MANOVA on PCA and MRPP on NMS revealed significant changes in the microbial community during the growing season. We used loading values of PCA to rank the abundances of bacterial species and found increases of some species in June and July.
