Spatial density‐dependent parasitism and specificity in the robber fly Mallophora ruficauda (Diptera: Asilidae)
Castelo, Marcela Karina; Corley, Juan Carlos (Wiley, 2010-02)The density‐dependence in parasitism by the robber fly Mallophora ruficauda (Diptera: Asilidae) on scarab beetle larvae (Coleoptera: Scarabaeidae) populations was studied in the present research. Mallophora ruficauda is a ... -
Spatial dynamics of a Sirex noctilio woodwasp population within a pine plantation in Patagonia, Argentina
Corley, Juan Carlos; Villacide, Jose Maria; Bruzzone, Octavio Augusto (Wiley, 2007-12)The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) is probably the most important pest of pine tree plantations of the southern hemisphere. We studied the spatial arrangement of an endemic population of the woodwasp ... -
Spatial pattern of attacks of the invasive woodwasp Sirex noctilio, at landscape and Stand Scale
Lantschner, Maria Victoria; Corley, Juan Carlos (2015-05-18)Invasive insect pests are responsible for important damage to native and plantation forests, when population outbreaks occur. Understanding the spatial pattern of attacks by forest pest populations is essential to improve ... -
Spatiotemporal outbreak dynamics of bark and wood-boring insects
Lantschner, Maria Victoria; Corley, Juan Carlos (Elsevier, 2023-02)Bark and wood-boring insects (BWI) can cause important disturbances in forest ecosystems, and their impact depends on their spatiotemporal dynamics. Populations are usually at stable, low densities but can be disrupted by ... -
Temperature explains variable spread rates of the invasive woodwasp Sirex noctilio in the Southern Hemisphere
Lantschner, Maria Victoria; Villacide, Jose Maria; Garnas, Jeffrey; Croft, Philip; Carnegie, Angus J.; Liebhold, Andrew M.; Corley, Juan Carlos (2014-02)La frecuencia de introducciones de no indígena insectos forestales en nuevos hábitats va en aumento en todo el mundo, a menudo con consecuencias profundamente negativas sobre los ecosistemas naturales y las plantaciones ... -
The Ambrosia Beetle Megaplatypus mutatus: A Threat to Global Broad-Leaved Forest Resources
Ceriani Nakamurakare, Esteban; Robles, Carolina; González-Audino, Paola; Dolinko, Andrés; Mc Cargo, Patricia; Corley, Juan Carlos; Allison, Jeremy; Carmarán, Cecilia (Entomological Society of America, 2022-08)We provide scientists and decision-makers with up-to-date information on Megaplatypus mutatus (Coleoptera: Curculionidae: Platypodinae), a forest insect native to South America that has invaded other regions. Emphasis is ... -
The Influence of Food and Con-specifics on the Flight Potential of the Parasitoid Ibalia leucospoides
Fischbein, Deborah; Corley, Juan Carlos; Villacide, Jose Maria; Bernstein, Carlos (Springer, 2011-11)For insect parasitoids, knowledge of their flight capability is essential for a general understanding of the relationship with their hosts. For instance, flight capacity might partly determine their efficacy as biological ... -
Trapping success and flight behavior of two parasitoid species of the woodwasp Sirex noctilio
Martinez Von Ellrich, Andres; Fischbein, Deborah; Villacide, Jose Maria; Corley, Juan Carlos (Elsevier, 2019-04-19)Classical biological control relies on the deliberate introduction of natural enemies to reduce pest populations below damage thresholds. Knowledge on key aspects of the behavior of antagonists and their population densities ... -
Weak trophic links between a crab-spider and the effective pollinators of a rewardless orchid
Quintero, Carolina; Corley, Juan Carlos; Aizen, Marcelo Adrian (2015-01)Sit and wait predators hunting on flowers are considered to be exploiters of plant–pollinator mutualisms. Several studies have shown that plant–pollinator interactions can be highly susceptible to the impact of a third ... -
Wind disrupts trail pheromone communication in the leaf-cutting ant Acromyrmex lobicornis
Alma, Andrea Marina; Buteler, Micaela; Martinez Von Ellrich, Andres; Corley, Juan Carlos (Elsevier, 2022-10)Although wind is a ubiquitous component of ecological systems and might affect pheromone communication, its effects have not been studied in depth. To test whether wind impacts trail pheromone behaviour, we studied the ... -
Worldwide diversity of endophytic fungi and insects associated with dormant tree twigs
Franic, Iva; Prospero, Simone; Adamson, Kalev; Corley, Juan Carlos; Lantschner, Maria Victoria; Soliani, Carolina; Eschen, René (Springer, 2022-03)International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated ...
