520			\|a Abstract A Green nanomaterial synthesis could be considered as an alternative bio-controller source of insect pest management as well as saving the environment. Gamma irradiation-induced silver nanoparticles (AgNPs) synthesis in an aqueous solution of irradiated polyvinyl pyrrolidone, (PVP) at ambient conditions was performed. A homogenous mixture solution consisting of (1 mmol $ Ag^{+} $) ions and irradiated (1% PVP) was subject to gamma rays of Co-60 at dose of 20 kGy. Concurrently, the radiolysis of water by γ-rays produced ($ H_{2} $, ehy and H·,OH·) that act as reducing agents and initiators for $ Ag^{0} $ production and PVP polymerization, respectively. The new absorption band observed at 420 nm is confirmed the formation (Ag/PVP) nanoparticles. The color of ($ AgNO_{3} $/PVP) solution converts from colorless to yellowish emphasizing the formation of (Ag/PVP) nanoparticles. The obtained results from X-ray diffraction (XRD) confirmed the coexistence of Ag nanoparticles and PVP matrix. The presence of PVP influenced the shape and distribution of the uniformly dispersed Ag/PVP nanoparticles with diameter 30 ± 5 nm. Bioassay of Ag/PVP nanoparticle on Spodoptera littoralis larvae indicated that the high concentration (600 ppm) of Ag/PVP nanoparticle gave only 11.5% mortality. The interaction between S. littoralis Nucleopolyhedrosis (SpliMNPV) and Ag/PVP nanoparticle had negative correlation to be considered as antagonism. Our finding indicated that the larvicidal activity of Ag/PVP nanoparticle was too low to consider as insecticide against S. littoralis. In the present study, the novelty is reduction of SpliMNPV pathogenicity as well as increased the virus degradation in response to UV irradiation is assisted by Ag/PVP nanoparticle.

Gamma irradiation-induced silver nanoparticles (AgNPs) synthesis in an aqueous solution of irradiated polyvinyl pyrrolidone, (PVP) at ambient conditions was performed. A homogenous mixture solution consisting of (1 mmol $ Ag^{+} $) ions and irradiated (1% PVP) was subject to gamma rays of Co-60 at dose of 20 kGy. Concurrently, the radiolysis of water by γ-rays produced ($ H_{2} $, ehy and H·,OH·) that act as reducing agents and initiators for $ Ag^{0} $ production and PVP polymerization, respectively. The new absorption band observed at 420 nm is confirmed the formation (Ag/PVP) nanoparticles. The color of ($ AgNO_{3} $/PVP) solution converts from colorless to yellowish emphasizing the formation of (Ag/PVP) nanoparticles. The obtained results from X-ray diffraction (XRD) confirmed the coexistence of Ag nanoparticles and PVP matrix. The presence of PVP influenced the shape and distribution of the uniformly dispersed Ag/PVP nanoparticles with diameter 30 ± 5 nm. Bioassay of Ag/PVP nanoparticle on Spodoptera littoralis larvae indicated that the high concentration (600 ppm) of Ag/PVP nanoparticle gave only 11.5% mortality. The interaction between S. littoralis Nucleopolyhedrosis (SpliMNPV) and Ag/PVP nanoparticle had negative correlation to be considered as antagonism.

Gamma irradiation-induced silver nanoparticles (AgNPs) synthesis in an aqueous solution of irradiated polyvinyl pyrrolidone, (PVP) at ambient conditions was performed. A homogenous mixture solution consisting of (1 mmol $ Ag^{+} $) ions and irradiated (1% PVP) was subject to gamma rays of Co-60 at dose of 20 kGy. Concurrently, the radiolysis of water by γ-rays produced ($ H_{2} $, ehy and H·,OH·) that act as reducing agents and initiators for $ Ag^{0} $ production and PVP polymerization, respectively. The new absorption band observed at 420 nm is confirmed the formation (Ag/PVP) nanoparticles. The color of ($ AgNO_{3} $/PVP) solution converts from colorless to yellowish emphasizing the formation of (Ag/PVP) nanoparticles. The obtained results from X-ray diffraction (XRD) confirmed the coexistence of Ag nanoparticles and PVP matrix. The presence of PVP influenced the shape and distribution of the uniformly dispersed Ag/PVP nanoparticles with diameter 30 ± 5 nm. Bioassay of Ag/PVP nanoparticle on Spodoptera littoralis larvae indicated that the high concentration (600 ppm) of Ag/PVP nanoparticle gave only 11.5% mortality. The interaction between S. littoralis Nucleopolyhedrosis (SpliMNPV) and Ag/PVP nanoparticle had negative correlation to be considered as antagonism. Our finding indicated that the larvicidal activity of Ag/PVP nanoparticle was too low to consider as insecticide against S. littoralis. In the present study, the novelty is reduction of SpliMNPV pathogenicity as well as increased the virus degradation in response to UV irradiation is assisted by Ag/PVP nanoparticle.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Gamma-Irradiation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ag/PVP</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Larvicidal activity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Baculovirus</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Silver nanoparticles</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sayed, Waheed A.

abstract	Abstract A Green nanomaterial synthesis could be considered as an alternative bio-controller source of insect pest management as well as saving the environment. Gamma irradiation-induced silver nanoparticles (AgNPs) synthesis in an aqueous solution of irradiated polyvinyl pyrrolidone, (PVP) at ambient conditions was performed. A homogenous mixture solution consisting of (1 mmol $ Ag^{+} $) ions and irradiated (1% PVP) was subject to gamma rays of Co-60 at dose of 20 kGy. Concurrently, the radiolysis of water by γ-rays produced ($ H_{2} $, ehy and H·,OH·) that act as reducing agents and initiators for $ Ag^{0} $ production and PVP polymerization, respectively. The new absorption band observed at 420 nm is confirmed the formation (Ag/PVP) nanoparticles. The color of ($ AgNO_{3} $/PVP) solution converts from colorless to yellowish emphasizing the formation of (Ag/PVP) nanoparticles. The obtained results from X-ray diffraction (XRD) confirmed the coexistence of Ag nanoparticles and PVP matrix. The presence of PVP influenced the shape and distribution of the uniformly dispersed Ag/PVP nanoparticles with diameter 30 ± 5 nm. Bioassay of Ag/PVP nanoparticle on Spodoptera littoralis larvae indicated that the high concentration (600 ppm) of Ag/PVP nanoparticle gave only 11.5% mortality. The interaction between S. littoralis Nucleopolyhedrosis (SpliMNPV) and Ag/PVP nanoparticle had negative correlation to be considered as antagonism. Our finding indicated that the larvicidal activity of Ag/PVP nanoparticle was too low to consider as insecticide against S. littoralis. In the present study, the novelty is reduction of SpliMNPV pathogenicity as well as increased the virus degradation in response to UV irradiation is assisted by Ag/PVP nanoparticle. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2021
