Diseño participativo de tecnologías para el manejo de la mosca Drosophila Suzukii en Patagonia
Fernandez, Manuela Teresa; De La Vega, Gerardo; Masague, Santiago; Do Eyo, M. De Las Mercedes; Soria Mercier, Lihuen; Parada, Eve; Melo, Natali; Ordoñez, Juan; Vica, Nicolas (Estación Experimental Agropecuaria Bariloche, INTA, 2024-07)Para promover el manejo de la mosca Drosophila suzukii sin el uso de insecticidas, una estrategia de desarrollo socio-productivo con redes de comercialización de fruta fina fue impulsada por personal técnico junto a ... -
Drosophila suzukii (Diptera: Drosophilidae) distribution modelling improves our understanding of pest range limits
De La Vega, Gerardo, José; Corley, Juan Carlos (Taylor & Francis, 2019)Spatial distributions models (SDM) are often used in invasive pest management to understand current and potential distribution. Using data on the well-studied spotted wing drosophila as a model, we compared distribution ... -
Ecological and physiological thermal niches to understand distribution of Chagas disease vectors in Latin America
De La Vega, Gerardo; Schilman, Pablo Ernesto (John Wiley & Sons Ltd, 2018-03)In order to assess how triatomines (Hemiptera, Reduviidae), Chagas disease vectors, are distributed through Latin America, we analysed the relationship between the ecological niche and the limits of the physiological thermal ... -
Effect of Drosophila suzukii on Blueberry VOC’s: Chemical Cues for a Pupal Parasitoid, Trichopria anastrephae
De La Vega, Gerardo; Triñanes, F.; Gonzalez, Andres (Springer, 2021-07)Biocontrol agents such as parasitic wasps use long-range volatiles and host-associated cues from lower trophic levels to find their hosts. However, this chemical landscape may be altered by the invasion of exotic insect ... -
Genetic assessment of the invasion history of Drosophila suzukii in Argentina
De La Vega, Gerardo; Corley, Juan Carlos; Soliani, Carolina (Springer Nature, 2019-08)Drosophila suzukii (Diptera: Drosophilidae) is a highly polyphagous fruit pest native to eastern Asia, which in the last decade had widely expanded its range and become a serious pest in the Americas and Europe. Invasion ... -
Genetic variation for tolerance to high temperatures in a population of Drosophila melanogaster
Rolandi, Carmen; Lighton, John R.B.; De La Vega, Gerardo; Schilman, Pablo Ernesto; Mensch, Julián (John Wiley & Sons Ltd, 2018-10)The range of thermal tolerance is one of the main factors influencing the geographic distribution of species. Climate change projections predict increases in average and extreme temperatures over the coming decades; hence, ... -
Insectos de importancia económica y sanitaria “Mosca de alas pintadas” Drosophila suzukii
De La Vega, Gerardo (Ediciones INTA, 2017-12)Desde 2013 en Argentina la producción de fruta fina, cereza y uva tiene una nueva amenaza. Se trata de la mosca de alas pintadas (Drosophila suzukii), una mosca oriunda del sudeste asiático capaz de atacar la fruta en pleno ... -
Modelling the establishment, spread and distribution shifts of pests
Lantschner, Maria Victoria; De La Vega, Gerardo; Corley, Juan Carlos (Taylor and Francis, 2019)During the last century increasing human trade networks have interacted with other global changes – such as land use and climate change – to accelerate the range expansion of pest species worldwide. In this special issue, ... -
“Mosca de alas pintadas”. Drosophila Suzukii
De La Vega, Gerardo (EEA Bariloche, 2018-12)La mosca Drosophila Suzukii, comunmente llamada "mosca de alas pintadas", es un insectos del grupo de los Dípteros, como los mosquitos, tábanos y moscas domésticas, los cuales se caracterizan por poseer un solo par de alas. ... -
La mosca de las alas manchadas Drosophila suzukii en la Comarca Andina
Martinez, Andres; Cardozo, Andrea; Masciocchi, Maite; Fischbein, Deborah; Germano, Monica Daniela; Chillo, María Verónica; De La Vega, Gerardo; Mariño, Javier; Garis, Gabriel (EEA Bariloche, 2022)La mosca de alas manchadas, Drosophila suzukii, es un díptero nativo de Asia que ha invadido gran parte del mundo causando importantes daños en cultivos de fruta, principalmente aquella de piel fina. En Argentina fue ... -
New records of the invasive pest Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) in the South American continent
Lavagnino, Nicolas Jose; Diaz, Beatriz Maria; Cichon, Liliana; De La Vega, Gerardo; Garrido, Silvina Alejandra; Lago, Jonatan; Fanara, Juan Jose (Sociedad Entomológica Argentina, 2018)The present study reports new presences of Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) in four localities in Argentina, extending its geographical range in South America. Among the new records, one is ... -
Oviposition substrate location by the invasive woodwasp Sirex noctilio: the combined effect of chemical cues emitted by its obligate symbiont Amylostereum areolatum and different host-tree species
Masague, Santiago; Fernández, Patricia Carina; Devescovi, Francisco; Segura, Diego Fernando; De La Vega, Gerardo; Corley, Juan Carlos; Villacide, Jose Maria; Martinez, Andres (Wiley, 2023-06)BACKGROUND: Sirex noctilio is an invasive forest wasp that affects pines and can result in severe economic losses. The use of semiochemicals offers an opportunity to develop sensitive and specific capturing systems to ... -
Sex, life history and morphology drive individual variation in flight performance of an insect parasitoid
Fischbein, Deborah; Villacide, Jose Maria; De La Vega, Gerardo; Corley, Juan Carlos (2017-08)1. The movement of organisms can be driven by multiple factors and has implications for fitness and the spatial distribution of populations. Insects spend a large proportion of their adult lives foraging by flying for ... -
The relevance of integrating multiple sensory modalities into capturing devices: the case of the global pest Sirex noctilio
