Addition of the selected optical brighteners Leucophor BS, Leucophor BSB, Phorwite AR, Phorwite RKH, and Tinopal LPW to the gypsy moth nuclear polyhedrosis virus (NPV) reduced the LC50from 18,000 polyhedral inclusion bodies (PIB)/ml to values between 10 (Phorwite RKH) and 44 (Leucophor BSB) PIB/m. These brighteners also reduced the LT50at every virus concentration tested. At the highest virus concentration (1 × 106 PIB/ml), LT50s were reduced from 13.9 to 7.1 d. The addition of Tinopal LPW to… Expand
Aerial Application of the Viral Enhancer Blankophor BBH with Reduced Rates of Gypsy Moth (Lepidoptera: Lymantriidae) Nucleopolyhedrovirus
TLDR
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
A gypsy moth (Lymantria dispar, Lepidoptera: Lymantriidae) multinucleocapsid nuclear polyhedrosis virus from France: comparison with a North American and a Korean strain
TLDR
In vivo bioassays showed that the French strain of L. dispar MNPV (LdMNPV) was the least active, whereas the North American strain had the highest activity. Expand
Baculovirus resistance in codling moth (Cydia pomonella L.) caused by early block of virus replication.
TLDR
It is indicated that CpGV can enter but not replicate in the cells of resistant codling moth larvae, suggesting a systemic block prior to viral DNA replication. Expand
The Effects of Cations on the Activity of the Gypsy Moth (Lepidoptera: Lymantriidae) Nuclear Polyhedrosis Virus
  • M. Shapiro
  • Biology, Medicine
  • Journal of economic entomology
  • 2001
TLDR
Four cations acted as viral enhancers, as indicated by reductions in LC50s, andFerrous and ferric chloride were inhibitory to larval growth and development as well as to virus activity. Expand
Field Tests with A Fluorescent Brightener to Enhance infectivity of Fall Armyworm (Lepidoptera: Noctuidae) Nuclear Polyhedrosis Virus
TLDR
The nuclear polyhedrosis virus (NPV) of fall armyworm, Spodoptera frugiperda, was applied in combination with Fluorescent Brightener 28 (Calcofluor White M2R, Tinopal LPW) to whorl-stage corn and interacted significantly with virus concentration and with water volume to increase larval mortality.

Relative Efficacies of Congo Red and Tinopal LPW on the Activity of the Gypsy Moth (Lepidoptera: Lymantriidae), Nucleopolyhedrovirus and Cypovirus
TLDR
Congo red and Tinopal LPW were assayed to determine their effects on the activity of the gypsy moth, Lymantria dispar, nucleopolyhedrovirus, LdMNPV and cypovirus infecting the Gypsy moth and it was found that Congo red reduced the median lethal concentration (LC50) by approximately 26-fold, whereas TinopalLPW reduced the LC50 by approximately 360-fold.

FIELD TESTS WITH A FLUORESCENT BRIGHTENER TO ENHANCE INFECTIVITY OF FALL ARMYWORM ( LEPIDOPTERA : NOCTUIDAE ) NUCLEAR POLYHEDROSIS VIRUS
The nuclear polyhedrosis virus (NPV) of fall armyworm, Spodoptera frugiperda (J. E. Smith), was applied in combination with Fluorescent Brightener 28 (Calcofluor White M2R, Tinopal LPW) toExpand
Enhanced Effect of Fluorescent Whitening Agent on Peroral Infection for Recombinant Baculovirus in the Host Bombyx mori L
TLDR
The effects of a fluorescent whitening agent on improving the oral infection for the recombinant Bombyx mori nuclear polyhedrin-negative baculovirus in silkworm larva and their possible mechanism were investigated and showed that the peroral infection can be remarkably enhanced by adding VBL into the larval artificial diet.

A Stilbene Optical Brightener can Enhance Bacterial Pathogenicity to Gypsy Moth (Lepidoptera: Lymantriidae) and Colorado Potato Beetle (Coleoptera: Chrysomelidae)
TLDR
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
Enhancement of the activity of a nuclear polyhedrosis virus by an optical brightener in the eastern hemlock looper , Lambdina fiscellaria fiscellaria ( Lepidoptera : Geometridae )
The pathogenicity of a nuclear polyhedros is virus ori ginally iso lated from Lambdina jisce/laria Iligubrosa (Hulst) was compared between treatments with and wi thout the optical brightenerExpand
