Acroclisoides sinicus is a pteromalid of Asian origin that has recently been detected in Europe and North America. It has been frequently found in association with several scelionid and eupelmid primary parasitoids of hemipteran eggs, including the brown marmorated stink bug Halyomorpha halys, leading us to suspect that A. sinicus is an obligate or facultative hyperparasitoid. Laboratory tests were conducted using pentatomid egg masses (H. halys, Acrosternum heegeri, and Dolycoris baccarum) parasitized by primary parasitoids, including Trissolcus japonicus, Trissolcus mitsukurii, Telenomus sp., Anastatus bifasciatus, and unparasitized H. halys egg masses, to test this hypothesis. Our studies confirmed that A. sinicus is an obligate hyperparasitoid of the pupal stage of scelionid primary parasitoids but not of eupelmid ones, at least under the tested conditions.
