2010 Annual Report 1a.Objectives (from AD-416) (1) Obtain information on the basic biology, life history and host specificity of natural enemies of invasive insect pests such as mirid plant bugs (Lygus spp., Adelphocoris spp.), brown marmorated stink bug (Halyomorpha halys), soybean aphid (Aphis glycines), and emerald ash borer (Agrilus planipennisi) and other new pests that may arise. (2) Facilitate introduction of natural enemies (parasitic Hymenoptera) of pests of interest to China and the USA. (3) Obtain and ship desired natural enemy species to the cooperators. 1b.Approach (from AD-416) Assist with field surveys for natural enemies (mainly parasitic Hymenoptera) of target pests (including Adelphocoris lineolatus, Lygus spp., Halyomorpha halys, Aphis glycines, Aphis gossypii, and Agrilus planipennisi) and field collections in the United States or China, depending on where they occur. Collect / provide data on relevant aspects of basic biology, life history, and host specificity of the natural enemies in China or the United States. Obtain Export and Import permits as needed and ship pure colonies of natural enemies (such as Peristenus spp., Tetrastichus spp., Spathius spp., Atanycolous spp.) to the destination country for further testing and/or release against intended target pests. 3.Progress Report During the reporting period, the Chinese cooperator requested assistance in obtaining natural enemies of mirid plant bugs for a biological control project in China, therefore BIIR initiated shipments of a parasitoid that is currently being released in the USA against tarnished plant bugs. To discuss the cooperative project, the ADODR corresponded by electronic mail with the cooperator and graduate students involved in the research, and a meeting was held at China Agricultural University to discuss the project during a trip conducted for foreign exploration in China in June 2010.
