Biological and molecular characterization of Rachiplusia nu single nucleopolyhedrovirus, a promising biocontrol agent against the South American soybean pest Rachiplusia nu
Jakubowicz, Violeta; Taibo, Catalina Beatriz; Sciocco, Alicia Ines; Arneodo Larochette, Joel Demian (Elsevier, 2019-09)Rachiplusia nu (Lepidoptera: Noctuidae) is a key soybean pest in Argentina. Current management of this moth relies mainly on the use of synthetic insecticides and transgenic plants. In search of biological control-based ... -
Biological and molecular features of Nosema rachiplusiae sp. n., a microsporidium isolated from the neotropical moth Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae)
Arneodo Larochette, Joel Demian; Sciocco, Alicia Ines (Springer, 2018-05)Light, electron microscopy and DNA analyses were performed to characterize a microsporidium infecting Rachiplusia nu larvae from a laboratory rearing in Argentina. Diplokaryotic spores were oval and measured 3.61 ± 0.29 ... -
Characterization of a new Helicoverpa armigera nucleopolyhedrovirus variant causing epizootic on a previously unreported host, Helicoverpa gelotopoeon (Lepidoptera: Noctuidae)
Ferrelli, Maria Leticia; Taibo, Catalina Beatriz; Fichetti, Patricia; Sciocco, Alicia Ines; Arneodo Larochette, Joel Demian (2016)This paper reports the first biological and molecular characterization of a nucleopolyhedrovirus isolated from the soybean and cotton pest Helicoverpa gelotopoeon. Studies were performed following a virus outbreak in a ... -
Comparative Pathogenesis of Generalist AcMNPV and Specific RanuNPV in Larvae of Rachiplusia nu (Lepidoptera: Noctuidae) Following Single and Mixed Inoculations
Decker Franco, Cecilia; Taibo, Catalina Beatriz; Di Rienzo, Julio A.; Alfonso, Victoria; Arneodo Larochette, Joel Demian (Oxford University Press, 2021-02-19)The South American soybean pest, Rachiplusia nu (Guenée), is naturally infected by Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and Rachiplusia nu nucleopolyhedrovirus (RanuNPV). We compared their pathogenicity ... -
Direct effect of ozone pollution on aphids: revisiting the evidence at individual and population scales
Telesnicki, Marta Cecilia; Martinez-Ghersa, Maria Alejandra; Arneodo Larochette, Joel Demian; Ghersa, Claudio Marco (2015-04)Most of our knowledge about the consequences of tropospheric ozone pollution on aphid–plant interaction assumes the absence of a direct effect of ozone on aphids. However, the biological effects of ozone encompass changes ... -
Exploring the factors involved in the absence of parasitism of Chaetosiphon fragaefolii by generalist parasitoids in strawberry
Francesena, Natalia; Arneodo Larochette, Joel Demian; Rocca, Margarita; Greco, Nancy Mabel (Springer, 2020-08)Chaetosiphon fragaefolii Cockerell (Hemiptera: Aphididae) is a worldwide strawberry pest with scarce records of parasitoids for its control. The parasitization rate of two generalist parasitoids, Aphidius colemani Viereck ... -
First identification of bacterial endosymbionts in three South-American spittlebug pests: Notozulia entreriana, Deois mourei and Deois knoblauchii
Foieri, Alvaro; Decker Franco, Cecilia; Marino de Remes Lenicov, Ana María; Arneodo Larochette, Joel Demian (Alma Mater Studiorum, Università di Bologna, 2022-06)Spittlebugs cause major pasture damage in the Neotropics. As most xylem-feeders, they depend on microbial symbionts to supply essential amino acids to their diet. Here, the obligate nutritional endosymbiont ‘Candidatus ... -
First report of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) infecting Chrysodeixis includens (Lepidoptera: Noctuidae) in Argentina
Arneodo Larochette, Joel Demian; Dami, Luciana Cecilia; Jakubowicz, Violeta; Alzogaray, Raúl Adolfo; Taibo, Catalina Beatriz (2018-09)Typical baculovirus infection symptoms were observed in Chrysodeixis includens Walker (Lepidoptera: Noctuidae) larvae from a laboratory rearing in Tucumán, Argentina. Scanning electron microscopy revealed the occurrence ... -
Genetic diversity of the polyphagous pest Rachiplusia nu across crops and locations in the Argentine Pampas
Decker Franco, Cecilia; San Blas, Germán; Balbi, Emilia Ines; Fichetti, Patricia; Puebla, Andrea Fabiana; Toledo, Andrea Vanesa; Arneodo Larochette, Joel Demian (Wiley, 2023-09-19)Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae, Plusiinae) is a defoliator of soybean (Glycine max L., Fabaceae), sunflower (Helianthus annuus L., Asteraceae), alfalfa (Medicago sativa L., Fabaceae), and horticultural ... -
Light microscopy of microsporidian spores and baculovirus occlusion bodies in Epinotia aporema and Helicoverpa gelotopoeon larval tissues, respectively
Arneodo Larochette, Joel Demian; Taibo, Catalina Beatriz; Sciocco, Alicia Ines (2016)Entomopathogens help regulate natural insect populations, and their use in pest management is the subject of active research. Classical and molecular techniques are currently available to elucidate disease etiology and ... -
