Notes on the hosts of Trissolcus Ashmead (Hymenoptera: Scelionidae) from China

Abstract

TrissolcusAshmead (Hymenoptera: Scelionidae) is a cosmopolitan genus of egg-parasitoid wasps associated with stink bugs (Pentatomidae, Scutelleridae, Urostylididae), many of which are important insect pests. Documentation of host associations for these wasps, which we here provide via museum specimens, can support their use as biological control agents of invasive stink bugs.The hosts of sevenTrissolcusspecies are reported from China:Trissolcus cultratus(Mayr) (hosts:Hippotiscus dorsalisStål, Pentatomidae;Urochela luteovariaDistant, Urostylididae),Trissolcus elasmuchae(Watanabe) (host:Niphe elongata(Dallas), Pentatomidae),Trissolcus japonicus(Ashmead) (hosts:Erthesina fullo(Thunberg), Pentatomidae;Rhaphigaster nebulosa(Poda), Pentatomidae),Trissolcus latisulcus(Crawford) (host:Poecilocoris latusDallas, Scutelleridae),Trissolcus mitsukurii(Ashmead) (host: Pentatomidae),Trissolcus semistriatus(Nees von Esenbeck) (host:Eurydemasp., Scutelleridae),Trissolcus yamagishiiRyu (host:Niphe elongata(Dallas), Pentatomidae).
