Efficient sampling of ground-dwelling arthropods using pitfall traps in arid steppes
Cheli, Germán Horacio; Corley, Juan Carlos (Sociedade Entomológica do Brasil, 2010-12)Pitfall trapping is probably the most frequently used method for sampling grounddwelling arthropods.

Galls were carefully ... -
Factors driving historic intercontinental invasions of European pine bark beetles
Vilardo, Gimena; Faccoli, Massimo; Corley, Juan Carlos; Lantschner, Maria Victoria (Springer, 2022-06)Largely assisted by global trade, alien insect species are being introduced into new territories at unprecedented rates. Among forest insects, pine bark beetles (Coleoptera: Curculionidae, Scolytinae) are a large and diverse ... -
Field preferences of the Social Wasp Vespula germanica (Hymenoptera: Vespide) for Protein-rich Baits

Se estudió la preferencia de un invasiva avispa, V. germanica, de alimentos ricos ... -
Flexible foraging decisions made by workers of the social wasp Vespula germanica (Hymenoptera: Vespidae) in response to different resources: influence of ontogenetic shifts and colony feedback
Mattiacci, Analia; Masciocchi, Maite; Corley, Juan Carlos (Wiley, 2022-04)Decisions made by foraging animals conform a complex process based on the integration of information from multiple external environmental stimuli and internal physiological signals, which in turn are modulated by individual ... -
Food and Host Searching Decisions Made by Ibalia leucospoides (Hymenoptera: Ibaliidae), a Parasitoid of Sirex noctilio (Hymenoptera:Siricidae)
Pietrantuono, Ana Laura; Fernandez Arhex, Valeria Cristina; Jofre, Nelida Raquel; Corley, Juan Carlos (2012-07)During their adult life, parasitoids—insects that lay eggs in or on other arthropods eventually killing them- spend a significant proportion of their lifetime searching for hosts, this behavior will determine their future ... -
Foraging behavior interactions between two non-native social wasps, Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) : implications for invasion success?
Pereira, Ana Julia; Pirk, Gabriela I.; Corley, Juan Carlos (2016-01)Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded – 35 yrs earlier – by another wasp, Vespula germanica. Although V. vulgaris ... -
Forest Health in the Southern Cone of America: State of the Art and Perspectives on Regional Efforts

The interaction of emerging invasive pests, climate change, and timber markets will define the ... -
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 ... -
Gustatory responsiveness in Vespula germanica workers: exploring the interplay between sensory perception and task specialization
Mattiacci, Analia; Mengoni Goñalons, Carolina; Masciocchi, Maite; Corley, Juan Carlos (Wiley, 2023-08-03)Workers’ task specialization and division of labor are critical features of social insects’ ecological success.
