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 ... -
Can early thinning and pruning lessen the impact of pine plantations on beetle and ant diversity in the Patagonian steppe?
Corley, Juan Carlos; Villacide, Jose Maria; Vesterinen, M. (2012)Pine plantations are thought to negatively impact species diversity and to irreversibly modify arid zones. However, some studies have suggested that through the application of appropriate management practices, the negative ... -
Can entomophagous nematodes slow the spread of invasive pest populations? The case study of Beddingia siricidicola released for the management of Sirex noctilio
Corley, Juan Carlos; Villacide, Jose Maria; Liebhold, Andrew M. (2014-12)Though rarely used in this way, biological control could potentially be exploited for managing spread of invasive species. Because spread of invasive species emerges from the combined action of population growth and ... -
Damage reduction of Acromyrmex lobicornis in Pinus ponderosa using mixed pine species in combination with push–pull tools
Alma, Andrea Marina; Fernández, Patricia; Serra, María Noel; Villacide, Jose Maria; Buteler, Micaela (Wiley, 2023-11)Leaf-cutting ants (LCAs) cause significant damage to forest plantations and are mainly managed by broad-spectrum synthetic insecticides. In Patagonia, Pinus ponderosa (Pinales: Pinaceae) (Douglas 1836) and Pinus contorta ... -
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, ... -
Distribution, Invasion History, and Ecology of Non-native Pine Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern South America

Ecology of the woodwasp Sirex noctilio : tackling the challenge of successful pest management
Villacide, Jose Maria; Corley, Juan Carlos (2012-08)The invasive woodwasp Sirex noctilio has become one of the most significant pests of pine forests throughout the northern and southern hemispheres. In Patagonia (southern Argentina), S. noctilio was first detected in the ... -
