Eight structurally related stilbene optical brighteners were compared as enhancers for the gypsy moth nuclear polyhedrosis virus (LdNPV). Five of the 8 brighteners acted as activity enhancers (Blankophor HRS, P167, BBH, RKH, and Tinopal LPW); but Blankophor BSU, DML, and LPG did not enhance the activity of LdNPV. The most effective brighteners (BBH, RKH, and LPW) reduced LC50s from 800- to 1,300-fold. LT50s were influenced by some brighteners (I-IRS, LPW, BBH, RKH) but not by others (LPG, DML… Expand
Relative Effectiveness of Selected Stilbene Optical Brighteners as Enhancers of the Beet Armyworm (Lepidoptera: Noctuidae) Nuclear Polyhedrosis Virus
Abstract The addition of a stilbene optical brightener, Tinopal LPW, at 1% concentration (wt:wt) significantly reduced the LC50 of the beet armyworm nuclear polyhedrosis virus (SeMNPV) from 2.9Expand
Optical brighteners as ultraviolet protectants and as enhancers in pathogenicity of Spodoptera litura (Fabricius) (Lep., Noctuidae) nucleopolyhedrovirus
The synergistic action of optical brighteners with SlMNPV was discussed, which found the time required for the virus to kill larvae was reduced by 24–27% at 1% concentration of brighteners, and the infectivity of the virus was found in the older larvae, which were resistant to SlM NPV. Expand
Viral-enhancing activity of various stilbene-derived brighteners for a Spodoptera litura (Lepidoptera: Noctuidae) nucleopolyhedrovirus
Disruption of the peritrophic membrane (PM) was observed only when the cutworm larvae were given brighteners that had viral-enhancing activity, which suggests that brighteners disrupt the PM that lines the insect midgut and facilitate NPV infection of midGut epithelial cells. Expand
Effect of optical brighteners on the insecticidal activity of a nucleopolyhedrovirus in three instars of Spodoptera frugiperda
It is concluded that virus formulations containing optical brighteners may be valuable for control of late instar lepidopteran pests. Expand
Stilbenes as enhancers for gypsy moth (Lepidoptera: Lymantriidae) nucleopolyhedrovirus
It is demonstrated that some stilbenes can act as enhancers, whereas others do not, and that two stilbene dyes and a stilBene optical brightener significantly increased the activity of LdNPV. Expand
A Stilbene Optical Brightener can Enhance Bacterial Pathogenicity to Gypsy Moth (Lepidoptera: Lymantriidae) and Colorado Potato Beetle (Coleoptera: Chrysomelidae)
The mechanism for increase in bacterial toxicity by optical brighteners is compatible with mechanisms proposed for enhancement based on viral/lepidopteran/optical brightener systems that are not dependent on replication. Expand
Viral-enhancing activity of an optical brightener for Spodoptera littoralis (Lepidoptera: Noctuidae) nucleopolyhedrovirus
In terms of speed of kill, the ST50 values of the baculovirus-infected larva were reduced from 210 to 159, 213 to 147, and 207 to 165 h for second-, third- and fourth-instar larvae, respectively, by the addition of the optical brightener at biologically equivalent doses. Expand
Differences in activity enhancement of a baculovirus by an optical brightener between Choristoneura fumiferana and Choristoneura occidentalis (Lepidoptera: Tortricidae)
CfMNPV was used to compare the levels of viral enhancement by an optical brightener between C. occidentalis and C. fumiferana and found variation in enhancement of viral activity was still unknown. Expand
Aerial Application of the Viral Enhancer Blankophor BBH with Reduced Rates of Gypsy Moth (Lepidoptera: Lymantriidae) Nucleopolyhedrovirus
Viral enhancement increased with increasing concentration of Blankophor BBH and that a concentration of 0.3% was required to cause >90% larval mortality in 2nd-stage gypsy moth larvae. Expand
Is it feasible to use optical brightener technology with a Baculovirus bioinsecticide for resource-poor maize farmers in mesoamerica?
Analysis of the results of eight independent field trials in Mexico and Honduras revealed a significant positive relationship between log virus dose and percentage mortality observed in S. frugiperda larvae, indicating that approximately 60% pest control can be achieved as a conservative estimate with virus application and the action of parasitoids for the price of a chemical insecticide.
