Cloning and characterization of the secreted hemocytic prophenoloxidases of Heliothis virescensKent S Shelby
USDA, Agricultural Research Service, Biological Control of Insects Research Laboratory, Columbia, Missouri 65203, USA
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...
Analysis of ESTs generated from immune-stimulated hemocytes of larval Heliothis virescensKent 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...
Iron levels change in larval Heliothis virescens tissues following baculovirus infectionHolly J R Popham
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...
Baculovirus induced transcripts in hemocytes from the larvae of Heliothis virescensJonathan E Breitenbach
Biological Control of Insects Research Laboratory, Agricultural Research Service, USDA, Columbia, MO 65203, USA
Viruses 3:2047-64. 2011..Using this method, we completed the first and most comprehensive gene expression survey of both baculoviral infection and host immune defense in lepidopteran larvae...
Plasma phenoloxidase of the larval tobacco budworm, Heliothis virescens, is virucidalKent 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...
Increased plasma selenium levels correlate with elevated resistance of Heliothis virescens larvae against baculovirus infectionKent S Shelby
USDA, Agricultural Research Service, Biological Control of Insects Research Laboratory, Columbia, MO 65203, USA
J Invertebr Pathol 95:77-83. 2007..Our results suggest that dietary Se levels are directly correlated with plasma Se levels, and that plasma Se levels are in turn correlated with baculovirus resistance...
Isolation and characterization of a baculovirus associated with the insect parasitoid wasp, Cotesia marginiventris, or its host, Trichoplusia niJames J Grasela
Biological Control of Insects Research Laboratory, USDA ARS 1503 S Providence Road, Research Park, Columbia, Missouri, 65203 3535 USA
J Insect Sci 8:1-19. 2008....
Changes in trace metals in hemolymph of baculovirus-infected noctuid larvaeHolly J R Popham
USDA, Agricultural Research Service, Biological Control of Insects Research Laboratory, 1503 S Providence Rd, Columbia, MO 65203, USA
Biol Trace Elem Res 146:325-34. 2012..virescens as well as both H. zea instars. Based on this analysis, metals were identified whose levels changed during development in both species and during the immune response of H. virescens larvae...
Uptake of dietary micronutrients from artificial diets by larval Heliothis virescensHolly J R Popham
Biological Control of Insects Research Laboratory, USDA, Agricultural Research Service, 1503 S Providence Rd, Columbia, MO 65203, USA
J Insect Physiol 52:771-7. 2006..Based on this analysis, metals were identified that might well impact the fitness of a given colony of insects in relation to their diet...
Potent virucidal activity in larval Heliothis virescens plasma against Helicoverpa zea single capsid nucleopolyhedrovirusHolly J R Popham
USDA, Agricultural Research Service, Biological Control of Insects Research Laboratory, 1503 S Providence Road, Columbia, MO 65203, USA
J Gen Virol 85:2255-61. 2004..Thus, in the plasma of larval lepidopterans, the enzyme phenol oxidase may act as a constitutive, humoral innate antiviral immune response...
