Progress Report Objectives (from AD-416): Conduct field surveys in Korea for indigenous Asian natural enemies of the brown marmorated stinkbug (Halyomorpha halys) and soybean aphid (Aphis glycines), determine their impact on these pests in Korea, document native host range and other life history information, and provide live natural enemy material of selected species to ARS cooperators for further evaluation as potential biological control agents of these invasive pests in the United States. Approach (from AD-416): 1) conduct field surveys in Korea for indigenous Asian natural enemies of the brown marmorated stinkbug (Halyomorpha halys) and soybean aphid (Aphis glycines); 2) determine the impact of natural enemies on these pests in Korea; 3) document the native host range of natural enemies and other life history information relevant to their potential use as biological control agents; 4) provide live material of selected natural enemy species to ARS cooperators for further evaluation as potential biological control agents of these invasive pests in the United States. Since their establishment in North America a few years ago, soybean aphid has become an important and damaging pest of soybeans, and populations of brown marmorated stink bug have continued to spread and have developed into a significant pest in various vegetable and tree fruits. Research to date indicates that natural enemies present in North America are not capable of limiting populations of these pests, therefore ARS has engaged in foreign exploration to identify Asian natural enemies that can exert high levels of impact. This project is an agreement that was initiated in September 2007 to provide long-term assistance in surveying for natural enemies of soybean aphid and brown marmorated stink bug in Korea and record significant biological information needed to assess their efficacy and host specificity. During the reporting period, new foreign exploration was planned to occur in August of 2011 in the southern part of South Korea to collect natural enemies of brown marmorated stink bug. A poster entitled �Population genetic structure of the soybean aphid from Asia and North America based on microsatellites� was prepared for presentation at the International Congress in Daegu, South Korea in August 2012. The ADODR and the Seoul National University cooperator co- organized a symposium on invasive insects for the Congress which included presentations on these two target pests.

During the reporting period, new foreign exploration in Korea to identify and collect natural enemies of soybean aphid and brown marmorated stink bug was planned for the fall months of 2011. To discuss project progress, the ADODR corresponded during the year by electronic mail with the cooperator, and a meeting with the cooperator was held in December 2010 at the annual meeting of the Entomological Society of America to discuss the project progress activities.

Additional details about the research can be found in the report for the parent project 1926-22000-018- 00D, CLASSICAL BIOLOGICAL CONTROL OF INSECT PESTS OF CROPS IN THE NORTHEASTERN U.S. During the reporting period, research was concluded that identified the various species of aphids that occur on the overwintering host plants of soybean aphid, from which natural enemies are obtained. To discuss project progress, the ADODR corresponded by electronic mail with the cooperator and graduate students involved in the research, and a meeting was held at Seoul National University to discuss the project progress during a trip conducted for foreign exploration in South Korea in July 2010.

Collections were made of free-living and overwintering stink bugs to determine rates of parasitism by natural enemies and identify these species. To monitor project progress, the ADODR corresponded by electronic mail with the cooperator and graduate students involved in the research, and a meeting was held at Seoul National University to discuss the project progress during a trip conducted for foreign exploration in South Korea in August 2009.

Significant Activities that Support Special Target Populations Since establishment in North America a few years ago SBA has become the most important pest of soybeans and BMSB has the potential to become a significant pest in soybeans and various tree fruits. Research to date indicates that parasites present in North America are not capable of limiting populations of these pests, therefore ARS has engaged in foreign exploration to identify Asian natural enemies that can exert high levels of impact. This project is a new agreement that was initiated in September 2007 to provide long-term assistance in surveying for natural enemies of SBA and BMSB in Korea and record significant biological information needed to assess their efficacy and host specificity. The research addresses National Program 304 Component V - Pest Control Technologies, Problem Statement �Traditional Biological Control�. During the reporting period, overwintering host plants of SBA were monitored at three sites and parasites were obtained from aphids at these sites. Parasites were obtained from collections of overwintering BMSB, and a colony of the stinkbugs was established for production of egg masses to be used as sentinels in field exposures to detect summer parasitism. To monitor project progress, the ADODR corresponded with the cooperator and his graduate students conducting the research by electronic mail, and a meeting is planned to discuss the project during upcoming foreign exploration in Korea during September 2008.
