Importance of host plant species, Neotyphodium endophyte isolate, and alkaloids on feeding by Spodoptera frugiperda (Lepidoptera: Noctuidae) larvae.
TLDR
The deleterious consequences of endophyte infection were easily masked by other factors in tall fescue, and chemical analysis of herbage from the plants used and results from a no-choice study failed to individually implicate any of the major known alkaloids in the observed effects on S. frugiperda.

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.

Life Table Parameters, Reproductive Rate, Intrinsic Rate of Increase, and Estimated Cost of Rearing Podisus maculiventris (Heteroptera: Pentatomidae) on an Artificial Diet
TLDR
It is shown that when fed an insect-free artificial diet during both the nymphal and adult stage, developmental time was prolonged, preoviposition period was extended, and reproductive rate (R0) and intrinsic rate of increase (r) were significantly lower than when fed larval insect prey at both nymphs and adult stages. Expand
Levels of chitinolytic activity during development of three entomopathogenic fungi
TLDR
Low activity was measured during the growth stage when the fungi initially penetrate the insect cuticle and maximum activity occurred at a time when N- acetylglucosamine is necessary both for fungal growth and conidia formation and when the conidiophore exits the host. Expand
Removing external DNA contamination from arthropod predators destined for molecular gut‐content analysis
TLDR
Use of this bleaching protocol, perhaps with minor modifications tailored to different predator–prey systems, should reliably eliminate external DNA contamination, thereby alleviating concerns about this possible source of cross‐contamination for mass‐collected arthropod predators destined for molecular gut‐content analysis. Expand
Host age preference of Microplitis mediator (Hymenoptera: Braconidae), an endoparasitoid of Mythimna separata (Lepidoptera: Noctuidae)
TLDR
The results of this study suggest that 2nd and 3rd instars of M. separata would be the best host stages for mass production of Microplitis mediator in the laboratory and thebest host instars to target for effective control in field releases. 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.
