A Review of the Biology, Ecology, and Management of the South American Locust, Schistocerca cancellata (Serville, 1838), and Future Prospects
Trumper, Eduardo Victor; Cease, Arianne J.; Cigliano, María Marta; Copa Bazán, Fernando; Lange, Carlos E.; Medina, Héctor E.; Overson, Rick P.; Therville, Clara; Pocco, Martina E.; Piou, Cyril; Zagaglia, Gustavo; Hunter, David (MDPI, 2022-01-06)In the first half of the twentieth century, the South American Locust (SAL), Schistocerca cancellata (Serville, 1838), was a major pest of agriculture in Argentina, Bolivia, Paraguay, Uruguay, and Brazil. From 1954–2014, ... -
Acrotomopus atropunctellus (Coleoptera: Curculionidae) preference for large sugarcane shoots mitigates damage to sugarcane crop
Perez, Maria Lucia del Pilar; Isas, Marcos Gerardo; Salvatore, Analia Ruth; García, José María; Trumper, Eduardo Victor (BioOne, 2017-09)The sugarcane weevil, Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae) is an increasingly important sugarcane pest in Argentina. Its emergence period overlaps with early stages of sugarcane phenology. ... -
Are all edges equal? Microclimatic conditions, geographical orientation and biological implications in a fragmented forest
Bernaschini, María Laura; Trumper, Eduardo Victor; Valladares, Graciela; Salvo, Adriana (Elsevier, 2019-08-01)In fragmented forests the edges experience changes in microclimatic conditions, which are referred to as “abiotic edge effect”, and differ according to geographical orientation and season. These microclimatic changes could ... -
Band movement and thermoregulation in Schistocerca cancellata
Piou, Cyril; Zagaglia, Gustavo; Medina, Hector E.; Trumper, Eduardo Victor; Rojo Brizuela, Ximena; Ould Maeno, Koutaro (Elsevier, 2022-01)At high density, juvenile locusts create marching hopper bands. Understanding the roles of temperature and vegetation on the movement of these bands shall allow to better forecast and control them. Following a hopper band ... -
Climate change expected to improve digestive rate and trigger range expansion in outbreaking locusts
Youngblood, Jacob P.; Cease, Arianne J.; Talal, Stav; Medina, Héctor e.; Rojas, Julio E.; Trumper, Eduardo Victor; Angilletta Jr, Michael J.; Harrison, Jon F.; Copa Bazán, Fernando (Wiley, 2022-07-01)Global climate change will probably exacerbate crop losses from insect pests, reducing agricultural production, and threatening food security. To predict where crop losses will occur, scientists have mainly used correlative ... -
Emergencia postinvernal y fluctuación poblacional de adultos del picudo perforador de la caña de azúcar, Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae)
Pérez, María Lucia del Pilar; Isas, Marcos Gerardo; Salvatore, Analia Ruth; Gastaminza, Gerardo; Romero, Eduardo; Trumper, Eduardo Victor (Estación Experimental Agroindustrial Obispo Colombres (EEAOC), 2021)El objetivo de este trabajo fue caracterizar la dinámica de emergencia postinvernal de Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae) y su fluctuación poblacional en la localidad de Ranchillos, departamento ... -
Field bands of marching locust juveniles show carbohydrate, not protein, limitation
Cease, Arianne J.; Trumper, Eduardo Victor; Medina, Héctor; Copa Bazán, Fernando; Frana, Jorge; Harrison, Jon; Joaquin, Nelson; Learned, Jennifer; Roca, Mónica; Rojas, Julio E.; Talal, Stav; Overson, Rick P. (Elsevier, 2023-09-19)Locusts are grasshoppers that migrate en masse and devastate food security, yet little is known about the nutritional needs of marching bands in nature. While it has been hypothesized that protein limitation promotes locust ... -
Global perspectives and transdisciplinary opportunities for locust and grasshopper pest management and research
Word Ries, Mira; Adriaansen, Chris; Aldobai, Shoki; Berry, Kevin; Bal, Amadou Bocar; Catenaccio, María Cecilia; Cigliano, María Marta; Cullen, Darron A.; Deveson, Ted; Diongue, Aliou; Foquet, Bert; Hadrich, Joleen; Hunter, David; Johnson, Dan L.; Karnatz, Juan Pablo; Lange, Carlos E.; Lawton, Douglas; Lazar, Mohammed; Latchininsky, Alexandre V.; Lecoq, Michel; Le Gall, Marion; Lockwood, Jeffrey; Manneh, Balanding; Overson, Rick P.; Peterson, Brittany F.; Piou, Cyril; Poot-Pech, Mario A.; Robinson, Brian E.; Rogers, Stephen M.; Hojun, Song; Springate, Simon; Therville, Clara; Trumper, Eduardo Victor; Waters, Cathy; Woller, Derek A.; Youngblood, Jacob P.; Long, Zhang; Cease, Arianne (Pensoft Publishers, 2024-05-20)Locusts and other migratory grasshoppers are transboundary pests. Monitoring and control, therefore, involve a complex system made up of social, ecological, and technological factors. Researchers and those involved in ... -
Importance of human capital, field knowledge and experience to improve pest locust management
Gay, Pierre-Emmanuel; Trumper, Eduardo Victor; Lecoq, Michel; Piou, Cyril (2021-07-27)BACKGROUND: A poorly organised risk management system may dysfunction when used. The consequences can be dramatic for those supposed to be protected. Since the 1960s, preventive control strategies, with field officers as ... -
Incidencia de Diatraea saccharalis (Lepidoptera: Pyralidae) sobre el rendimiento del cultivo de maíz y cálculo de niveles de daño económico
Serra, Gerardo Victor; Trumper, Eduardo Victor (Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2020-06-25)Diatraea saccharalis es una plaga clave del cultivo de maíz en la región pampeana argentina. Los umbrales económicos que se utilizan no están basados en un cálculo actual del nivel de daño económico. Los objetivos de este ... -
