An Effective Cold Storage Method for Stockpiling Halyomorpha halys (Hemiptera: Pentatomidae) Eggs for Field Surveys and Laboratory Rearing of Trissolcus japonicus (Hymenoptera: Scelionidae).

An effective stockpiling method for egg masses of the invasive brown marmorated stink bug (Halyomorpha halys [Stål]; Hemiptera: Pentatomidae) would be useful for rearing and field studies of its egg parasitoid Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae). The current method of stockpiling H. halys egg masses at subzero temperatures has lethal and sublethal fitness consequences for T.
