Investigate natural enemies of emerald ash borer in Far East: inventory biotic agents, assess role in population dynamics of pest, set priorities for importation, and ship promising species to Newark for further study. Candidate species that appear to be monophagous or oligophagous, or which have many suspect host records will be subjected to laboratory tests in quarantine on North American species selected for study. Both choice and no-choice tests will be used in evaluating host range. Study natural enemies of indigenous buprestid beetles to identify effective candidate species that could be used effectively against EAB in North America. Experiments will be conducted to find optimum temperatures, relative humidity, and photoperiod needed to rear the most promising species. Releases will be made in areas having moderate to high host populations. Monitoring of EAB population density and natural enemy buildup and dispersal after colonization will be used to interpret the efficacy of biological control agents established. Screen incoming shipments of natural enemies of other pests for other ARS CRIS units as well as other institutions involved with biological control research, to remove undesirable organisms and obtain pure cultures of natural enemies other invasive species. Ship approved natural enemies to cooperators.
