Behavioural response of the woodwasp Sirex noctilio to volatile emissions of its fungal symbiont
Fernandez Ajo, Alejandro Apolo; Martinez Von Ellrich, Andres; Villacide, Jose Maria; Corley, Juan Carlos (2015-01)The wood-boring wasp, Sirex noctilio, is a global invasive pest that infects and kills pine trees by inoculating spores of a symbiotic fungus (Amylostereum areolatum) at oviposition. Wasp larvae depend on fungal growth to ... -

Dispersal behavior of yellowjacket (Vespula germanica) queens
Masciocchi, Maite; Martinez Von Ellrich, Andres; Pereira, Ana Julia; Villacide, Jose Maria; Corley, Juan Carlos (2018-02)Understanding the factors that affect animal dispersal behavior is important from both fundamental and applied perspectives. Dispersal can have clear evolutionary and ecological consequences, but for nonnative insect pests, ... -
Drone aggregation behavior in the social wasp Vespula germanica (Hymenoptera: Vespidae): Effect of kinship and density
Masciocchi, Maite; Angeletti, Bárbara; Corley, Juan Carlos; Martinez Von Ellrich, Andres (Nature Research, 2020-04)Inbreeding can have negative consequences on population viability because of the reduced fitness of the progeny. In general, most species have developed mechanisms to minimize inbreeding such as dispersal and kin avoidance ... -
Host selection by Ibalia leucospoides based on temporal variations of volatiles from the hosts’ fungal symbiont
Jofre, Nelida Raquel; Pildain, María Belén; Cirigliano, A.M.; Cabrera, G.M.; Corley, Juan Carlos; Martinez Von Ellrich, Andres (2016-12)Insect parasitoids locate hosts via reliable and predictable cues such as volatile emissions from hosts and/or host plants. For insects that depend on mutualistic organisms, such as many wood-boring insects, symbiont-derived ... -
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. Megarhyssa nortoni (Cresson) (Hymenoptera: Ichneumonidae) is a parasitoid of siricid wasp larvae which are concealed inside tree ... -
Insectos plaga de las plantaciones forestales
Lantschner, Maria Victoria; Villacide, Jose Maria; Martinez Von Ellrich, Andres (Ministerio de Agroindustria, Presidencia de la Nación, 2018)Una manera efectiva de abordar la sanidad de los cultivos forestales es mediante la implementación de una estrategia de Manejo Integrado de Plagas (MIP). Esta estrategia combina acciones de vigilancia y monitoreo, prevención ... -
Management of Sirex noctilio populations in exotic pine plantations: critical issues explaining invasion success and damage levels in South America
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 ... -
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 ... -
