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 ... -
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 ... -
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 ... -
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 ...
