Use of Optical Brighteners as Radiation Protectants for Gypsy Moth (Lepidoptera: Lymantriidae) Nuclear Polyhedrosis Virus
Twenty-three optical brighteners were tested as radiation protectants for the gypsy moth nuclear polyhedrosis virus (NPV) and at lower concentrations, Phorwite AR and Tinopal LPW were superior UV protectants. Expand
Fluorescence and Relative Activities of Stilbene Optical Brighteners as Enhancers for the Gypsy Moth (Lepidoptera: Lymantriidae) Baculovirus
Eight structurally related stilbene optical brighteners were compared as enhancers for the gypsy moth nuclear polyhedrosis virus (LdNPV) and found the most active brighteners tended to exhibit the greatest fluorescence, and the least active brightener tended to display the least fluorescence.

Infectivity of Fall Armyworm (Lepidoptera: Noctuidae) Nuclear Polyhedrosis Virus Enhanced by a Fluorescent Brightener
Studies were designed to determine the effect of the optical brightener, Tinopal LPW, on the infectivity of two preparations each of two isolates of the fall armyworm, Spodoptera frugiperda (J. E.Expand
Effect of Neem Seed Extract upon the Gypsy Moth (Lepidoptera: Lymantriidae) and Its Nuclear Polyhedrosis Virus
The addition of neem extract to the gypsy moth nuclear polyhedrosis virus, however, resulted in faster virus-caused mortality, as measured by LC50s. Expand
Green tea extracts as ultraviolet protectants for the beet armyworm, Spodoptera exigua, nucleopolyhedrovirus
The addition of a caffeinated green tea to the nucleopolyhedrovirus (SeMNPV) of the beet armyworm, Spodoptera exigua (Hübner), provided almost complete protection following UVB irradiation in laboratory tests. Expand
Enhanced Effectiveness of Lymantria dispar (Lepidoptera: Lymantriidae) Nucleopolyhedrosis Virus Formulated with Boric Acid
Two acids (sorbic and boric) appeared to enhance viral activity, as expressed by increased mortality in treated larvae, and in each test boric acid significantly enhanced viral activity. Expand
Enhancement of Gypsy Moth (Lepidoptera: Lymantriidae) Baculovirus Activity by Optical Brighteners
The magnitude of reduction in LC50s and LT50S in Gypsy moth larvae indicated that selected brighteners greatly enhanced the virulence of the gypsy moth NPV. Expand
Yield and Activity of Gypsy Moth (Lepidoptera: Lymantriidae) Nucleopolyhedrosis Virus Recovered from Survivors of Viral Challenge
A high positive correlation was observed between mortality in progeny and NPV-induced mortality in the parental generation, andNPV activity increased in proportion to incidence of original virus-induced larval mortalities. Expand
Helicoverpa armigera granulovirus interference with progression of H. zea nucleopolyhedrovirus disease in H. zea larvae.
The time study results imply that HaGV might be outcompeting HzSNPV by inhibiting its replication, and observed that H. zea larvae treated with high dosages of HaGV were initially stunted but had survival times similar to those of larvaetreated with lower dosages. Expand
Control of fatty acid metabolism. I. Induction of the enzymes of fatty acid oxidation in Escherichia coli.
Escherichia coli grows on long-chain fatty acids after a distinct lag phase, indicating that fatty acid oxidation in this bacterium is an inducible system and the inhibitory effect of glucose may be explained in terms of catabolite repression. Expand
