    Arch Insect Biochem Physiol 69:127-42. 2008
    ..Thus, even though prophenoloxidase subunits are constitutively expressed at high levels in larval H. virescens hemocytes and fat bodies, the subunit HvPPO-1 is differentially regulated by bacterial and baculoviral infection...

    Kent S Shelby
    USDA, Columbia, MO 65203, USA
    J Invertebr Pathol 101:86-95. 2009
    ..The ESTs reported here are the first large scale report of the H. virescens immunome responding to entomopathogens, and represent a first step to a more complete transcriptome for this pest moth...

    USDA, Agricultural Research Service, Biological Control of Insects Research Laboratory, 1503 S Providence Rd, Columbia, MO 65203, USA
    Biol Trace Elem Res 148:356-62. 2012
    ..In both studies, hemolymph Fe levels were higher in HzSNPV infected larvae. This first study of tissue Fe levels during viral infection of an insect clearly demonstrates that Fe homeostasis is substantially disrupted...

    Kent S Shelby
    USDA, Agricultural Research Service, Biological Control of Insects Research Laboratory, Columbia, MO 65203, USA
    J Insect Sci 6:1-12. 2006
    ..Our results confirm that phenoloxidase is the predominate activity in larval plasma accounting for inactivation of HzSNPV in vitro, and that phenoloxidase-dependent H(2)O(2) production may contribute to this virucidal activity...
