Uptake, flow, and digestion of casein and green fluorescent protein in the digestive system of Lygus hesperus Knight.
TLDR
Durations of passage and rates of absorption, digestion, and excretion were determined for a digestible protein, a non-digestible protein (casein), a green fluorescent protein, GFP, and aNon-Digestible carbohydrate (dextran) in the western tarnished plant bug, Lygus hesperus Knight. Expand
Host regulation and release of parasitism-specific proteins in the system Toxoneuron nigriceps-Heliothis virescens.
TLDR
The braconid wasp Toxoneuron nigriceps induced qualitative and quantitative changes in the protein composition of the moth Heliothis virescens host hemolymph, and incubation of host derived tissues, parasitoid larvae and teratocytes in 35S conditioned media suggested PSPs were a product of teratocyte. Expand
Potent virucidal activity in larval Heliothis virescens plasma against Helicoverpa zea single capsid nucleopolyhedrovirus.
TLDR
In the plasma of larval lepidopterans, the enzyme phenol oxidase may act as a constitutive, humoral innate antiviral immune response, which could limit the spread of virus from initial infective foci within the haemocoel. Expand
Effect of different host substrates on hemipteran salivary protein profiles *
TLDR
Starved insects fed and salivated more than the non-starved insects, yet the protein components of the saliva were similar, and in contrast to the phytophagous insects, P. maculiventris showed minimal differences in salivary protein profiles after feeding on Trichoplusia ni or an artificial diet. Expand
Characterization of digestive proteolytic activity in Lygus hesperus Knight (Hemiptera: Miridae).
The tarnished plant bug, Lygus hesperus Knight, is a pest that causes considerable economic losses to vegetables, cotton, canola, and alfalfa. Detailed knowledge of its digestive physiology willExpand
Morphology and Histology of the Alimentary Canal of Lygus hesperus (Heteroptera: Cimicomoropha: Miridae)
TLDR
Light microscopy study suggests that the three cell types in the Lygus gut cells are nondifferentiated regenerative cells, endocrine cells, and columnar cells, which strongly resemble those cell types seen in other insects. Expand
Effect of the Ectoparasite Necremnus breviramulus (Hymenoptera: Eulophidae) and Its Venom on Natural and Factitious Hosts
TLDR
The protein composition of the venom from N. breviramulus differed from other eulophids tested and did not contain the molt-arresting protein found in Euplectrus spp, and the difference in venom proteins may account for the different physiological effects and host range of these eulophile parasites. Expand
Molecular profiling of proteolytic and lectin transcripts in Homalodisca vitripennis (Hemiptera: Auchenorrhyncha: Cicadellidae) feeding on sunflower and cowpea.
TLDR
Documenting both the presence and variation of transcript expression involved in putative digestive proteolysis in this xylem-feeding leafhopper is noteworthy and aids efforts to design specific diet formulations for mass production of hosts and parasitoids to be used as effective biological control measures. Expand
Characteristics of a developmental arrestant in the venom of the ectoparasitoid wasp Euplectrus comstockii.
TLDR
Venomous protein, separated by electrophoretic techniques, with a native mol. Expand
Nutrigenomics: a case study in the measurement of insect response to nutritional quality
TLDR
Preliminary results of microarray and subtractive hybridization experiments that represent the feasibility of using nutrigenomics to assist in analyzing insect responses to nutritional changes and dietary quality are presented with the intent of stimulating further studies in this area. Expand
