Abstract The addition of a caffeinated green tea, Camellia sinensis L., filtrate (1%) to the nucleopolyhedrovirus (SeMNPV) of the beet armyworm, Spodoptera exigua (Hübner), provided almost complete protection following UVB irradiation (30 min) in laboratory tests. There were few differences in UV protection when extracts were prepared at 27 or at 90°C. Moreover, few differences in UV protection were demonstrated following infusion times of 5, 15, 30, and 60 min at 90°C. At a 1% concentration… Expand
Tea, Coffee, and Cocoa as Ultraviolet Radiation Protectants for the Beet Armyworm Nucleopolyhedrovirus
TLDR
It is demonstrated that coffee was comparable to green tea and black tea as a UV protectant, and further studies should be conducted to optimize their use in biopesticide formulations. Expand
Fruit and Vegetable Extracts as Radiation Protectants for the Beet Armyworm Nucleopolyhedrovirus1
TLDR
It was determined that herbs and spices contained much higher levels of antioxidants and phenolics than fruits and vegetables, and selection of extracts with high levels of both antioxidants and total phenolics resulted in increased UV protection. Expand
Fruit and Vegetable Extracts as Radiation Protectants for the Beet Armyworm Nucleopolyhedrovirus 1
Extracts from 37 fruits and vegetables were tested as ultraviolet (UV) protectants for the nucleopolyhedrovirus (SeMNPV) of the beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae).Expand
Plant Extracts as Ultraviolet Radiation Protectants for the Beet Armyworm (Lepidoptera: Noctuidae) Nucleopolyhedrovirus: Screening of Extracts
TLDR
Findings indicate that these plant extracts may be useful UV protectants for the SeNPV and they should be investigated further to obtain more efficacious formulations for the control of agriculturally important insect pests. Expand
Field Evaluation of a Kudzu/Cottonseed Oil Formulation on the Persistence of the Beet Armyworm Nucleopolyhedrovirus
TLDR
The greatest UV protection for SeMNPV was achieved when cottonseed oil/lecithin were used in conjunction with kudzu, which resulted in an increase of both UVB (280 - 320 nm) and UVA (320 - 400 nm) absorbance. Expand
Additives for a Baculovirus against ultraviolet effect
TLDR
Findings indicate that theses plant extracts could be promising UV protective additives for SpliNPV and they should be further investigated in the field large scale to obtain the best formulation for the control of agriculture important insect pest. Expand
Plant Phenolics as Radiation Protectants for the Beet Armyworm (Lepidoptera: Noctuidae) Nucleopolyhedrovirus
TLDR
Thirteen phenolics were tested as ultraviolet (UV) protectants for the nucleopolyhedrovirus (SeMNPV) of the beet armyworm, Spodoptera exigua (Hübner), and only caffeic acid, chlorogenic acid, and gallic acid provided some UV protection. Expand
Evaluation of Natural Additives to Enhance the Persistence of Spodoptera littoralis (Lepidoptera: Noctuidae) Nucleopolyhedrovirus (SpliMNPV) Under Field Conditions in Saudi Arabia.
TLDR
When applied on cabbage in the field during sunny summer conditions, clove and henna extracts enhanced the persistence of SpliMNPV by twofold, and these findings are encouraging to be applied in theField studies. Expand
Biological and Microbial Control Evaluation of Natural Additives to Enhance the Persistence of Spodoptera littoralis ( Lepidoptera : Noctuidae ) Nucleopolyhedrovirus ( Spli MNPV ) Under Field Conditions in Saudi Arabia
Nucleopolyhedrovirus is an effective biocontrol agent but for its biggest disadvantage of short persistence under sunlight conditions. In this study, 10 plant extracts were evaluated as ultravioletExpand
Increasing the efficacy of the cotton leaf worm Spodoptera littoralis nucleopolyhedrosis virus using certain essential oils
TLDR
The results suggested that the combination treatment of orange oil and SpliMNPV could be used as an effective method for the cotton leaf worm, Spodoptera littoralis (Boisd.), management. Expand

Ultraviolet Protectants of the Gypsy Moth (Lepidoptera: Lymantriidae) Nucleopolyhedrosis Virus
TLDR
All materials, with the exception of homomenthyl salicylate and 2-hydroxy-4-methoxybenzophenone, at least doubled viral persistence and p -aminobenzoic acid compounds enhanced persistence. Expand
Effectiveness of B Vitamins as Uv Screens for the Gypsy Moth (Lepidoptera: Lymantriidae) Nucleopolyhedrosis Virus
TLDR
Folic acid and riboflavin were superior protectants, and enhanced UV tolerance by 3.3- and 3.4-fold, respectively, while the addition of pantothenic acid, pyridoxine, folic acid, and rib oflavin protected NPV. Expand
Relative Effects of Ultraviolet and Visible Light on the Activities of Corn Earworm and Beet Armyworm (Lepidoptera: Noctuidae) Nucleopolyhedroviruses
TLDR
Five different combinations of fluorescent tubes were used to determine relative effects of UV and visible light on the nucleopolyhedroviruses of Helicoverpa zea and Spodoptera exigua, and the NPV from H. zea was found to be more sensitive to UV radiation than theNPV from S.Exigua. Expand
Antioxidant and Oxidative Enzyme Effects on the Inactivation of Inclusion Bodies of the Heliothis Baculovirus by Simulated Sunlight-UV
TLDR
The increased UV stability provided by an antioxidant or oxidative enzyme supports the hypothesis that reactive radicals, generated by SUV, can cause inactivation of field-applied viral and other microbial insecticides. Expand

  • 1969
TLDR
When the known granulosis virus of Pieris brassicae was exposed to ultraviolet radiation from a germicidal lamp it was much more rapidly inactivated in pure films than in films of crude virus, where colored and solid impurities were present. Expand
Field activity and storage stability of Anagrapha falcifera nucleopolyhedrovirus (AfMNPV) in spray-dried lignin-based formulations.

It is demonstrated that AfMNPV in lignin-based spray-dried formulations had a shelf-life of up to 3 mo at 30 degrees C and up to 30 mo at 4 degrees C, and with longer residual insecticidal activity in the field compared with unformulated or a glycerin formulation. Expand
Tests on protectants for foliar deposits of a polyhedrosis virus
TLDR
A combination of egg albumen and India ink was the most effective protectant with much of the original activity of residues being retained beyond 17 days after application, and without an additive, residues retained about 20% of original activity after the seventh day. Expand
Persistence of Heliothis Npv on Foliage of Cotton, Soybean, and Tomato
TLDR
The Heliothis nuclear polyhedrosis virus was rapidly inactivated under field conditions on the upper leaf surface of cotton, soybean, and tomato and persistence on tomato was significantly better than on the other hosts. Expand
