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, ... -
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, ... -
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 ...
