Host-related volatile cues used by a parasitoid wasp during foraging for its woodboring host
Fischbein, Deborah; Villacide, Jose Maria; Lopez, Bárbara; Corley, Juan Carlos; Martinez Von Ellrich, Andres (Wiley, 2018-12)Parasitoids relymainly on infochemicals to search for their herbivore hosts to oviposit on.

Invasive Insects in Forest Plantations of Argentina: Ecological Patterns and Implications for Management
Corley, Juan Carlos; Villacide, Jose Maria; Lantschner, Maria Victoria (Springer Nature, 2020-02)Since the dawn of modern agriculture, humans have selected a few several species from the immense diversity nature has to offer, resulting in the same species being cultivated in very different countries and regions. Crops ... -
Landscape configuration modulates the presence of leaf-cutting ants in eucalypt plantations
Cavigliasso, Pablo; González, Ezequiel; Scherf, Abel Nicolás; Villacide, Jose Maria (Springer Nature, 2023-08)Pest responses to landscape complexity show variable patterns globally, primarily related to species traits and specific managed habitats.

Corley, Juan Carlos; Lantschner, Maria Victoria; Martinez Von Ellrich, Andres; Fischbein, Deborah; Villacide, Jose Maria (Springer Nature, 2018-11)Plantation forestry with non-native trees is steadily increasing in the southern hemisphere and alien pest problems are also accumulating, as a consequence of the growing international movement of people and goods. Here, ... -
Mate-searching behavior in the invasive German wasp, Vespula germanica, in Patagonia
Martinez Von Ellrich, Andres; Masciocchi, Maite; Pisman, Natalia; Villacide, Jose Maria; Corley, Juan Carlos (John Wiley & Sons Ltd, 2018-07)In order to increase the probability of reproduction, social insects can adopt various mate‐finding strategies, such as increasing densities of males at specific locations, and/or visual and chemical cues that attract the ... -
“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. ... -
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 ... -
