○ 멸강나방에 대한 작물별 방제약제를 정리한 결과,벼와 옥수수는 각각 펜토에이트 유제 등 2종, 기장은 에마멕틴벤조에이트 유제 등 6종, 조는 사이안트라닐리프롤 유상수화제 등 4종을 우수 방제약제를 선발함

□ Purpose&Contents
This study was conducted to Analysis of ecological characteristics and development technique to optimal use insecticides of ricearmyworm. By analyzing the genetic and ecological characteristicsof white-backed planthoppers, the purpose of securing effectivecontrol information is to identify the source of origin and predict its spread after landing in Korea.
□ Results
Adults of oriental armyworm, Mythimna separata, was attracted from early april in sex pheromone-baited traps and the highest peak period of occurrence was from 28 May to 2 June. Adults was migrated from china in spring season ray eggs in rice crops such as italian_ryegrass in mid-april, and hatched larvae are occurrence in rice crops in early may, so early monitoring isnecessary to find larvae from may. When corn traps and tube-type sex pheromones were used, the height of trap was set to 110cm and sex pheromones were replaced every 4 weeks, the attracting effects of adult oriental armyworm was highest. As a results of investigating the date of occurrence of oriental armyworm in Buan area using the low threshold temperature of 10℃, it was similar that the occurrence data of oriental armyworm between the model for predicting and actually occurred in field. Also, in the Buan area, the larvas of oriental armyworm can develop from mid-april. As a result of the bioassay of oriental armyworm, rice and corm were selected for 2 pesticides including Phenthoate EC, and proso millet, 6 pesticides such as Emamectin_benzoate EC, and 4 pesticides, including Cyantranilliprole EW for foxtail millet. Pesticides of same strain had a large difference in the mortality. Therefore, when controlling with pesticides, use selected pesticides for each crop, It is recommended to use pesticides with different strain’s if controlled more than once.
As a result of analyzing the 18S rRNA ITS, the Honam province group in China and the Hadong group in Gyeongnam were similar, but the difference between the domestic groups was confirmed. For three years ('18~'20), we have not been able to confirm the viruliferous insect rate of southern rice black-streaked dwarf virus, a virus that mediates white-backed planthoppers. As for the biological characteristics of white-backed planthoppers, the growth period may vary depending on the host as the growth decline was confirmed in the cultivar resistance. Due to the increase the fecundity, there is a possibility that the density increases rapidly under favorable environmental conditions after migratory. When comparing the ecological differences between the groups in the white-backed planthopper through the life table, it was confirmed that there was a difference between the local groups, and it was judged that it could be changed due to environmental differences after migratory into the country.
□ Expected Contribution
Utilization as basic date for control using the occurrence and bioassay results of the oriental armyworm. Educate agricultural-related public officials and farmers on the technology for forecasting and control of oriental armyworm, and use them for field technical support. Establish a database of occurrence data of migrating moth pests and use them as prediction data of occurrence in future.
Through the group analysis and population change prediction technology of white-backed planthoppers, effective control methods such as selection of pesticides can be suggested through the prediction of the growth rate of generation after landing, and the selection of pesticides through the identification of the source of origin.
