Habituation in mosquito larvae Aedes aegypti is context-specific
Pietrantuono, Ana Laura; Aguirre Urreta, María Beatriz; Bruzzone, Octavio Augusto; Guerrieri, Fernando J. (The Company Biologists, 2021-06)Mosquito larvae live in water and perform a stereotyped escape response when a moving object projects its shadow on the surface, indicating potential risk of predation. Repeated presentations of the shadow induce a decrease ... -

Influence of adult diet on fitness and reproductive traits of the egg parasitoid Anagrus virlai (Hymenoptera: Mymaridae), a potential biocontrol agent against the corn leafhopper
Hill, Jorge Guillermo; Aguirre, María Belén; Bruzzone, Octavio Augusto; Virla, Eduardo Gabriel; Luft Albarracin, Erica (Wiley, 2020-08)Dalbulus maidis is the most important leafhopper pest of maize in the Americas. Anagrus virlai is an egg parasitoid commonly associated with the corn leafhopper. We evaluated whether the performance of A. virlai is dependent ... -
Influence of competition and intraguild predation between two candidate biocontrol parasitoids on their potential impact against Harrisia cactus mealybug, Hypogeococcus sp. (Hemiptera: Pseudococcidae)
Aguirre, María Belén; Bruzzone, Octavio Augusto; Triapitsyn, Serguei V.; Diaz Soltero, Hilda; Hight, Stephen D.; Logarzo, Guillermo Alejandro (Springer Nature, 2021-06-28)When two or more parasitoid species, particularly candidates for biocontrol, share the same target in the same temporal window, a complex of behaviors can occur among them. We studied the type of interactions (competition ... -
Intra-host interspecific larval parasitoid competition solved using modelling and bayesian statistics
Bruzzone, Octavio Augusto; Logarzo, Guillermo Alejandro; Aguirre, María Beatriz; Virla, Eduardo Gabriel (Elsevier, 2018-07)Intraguild competition is a complex phenomenon that shapes parasitoid communities. When several species of parasitoids oviposit within the same individual host, a complex phenomenon of larval competitive interaction occurs. ... -
Optimal automatic enhanced ERA5 daily precipitation data for environmental and agricultural monitoring tools in scarce data regions
Perri, Daiana Vanesa; Hurtado, Santiago Ignacio; Bruzzone, Octavio Augusto; Easdale, Marcos Horacio (Springer, 2023-11-10)The development of monitoring and early warning tools for environmental and agricultural applications is highly restricted in scarce climate data regions. In particular, precipitation data is a key input for several ... -
Phases or regimes? Revisiting NDVI trends as proxies for land degradation
Easdale, Marcos Horacio; Bruzzone, Octavio Augusto; Mapfumo, Paul; Tittonell, Pablo Adrian (Wiley, 2018-03)One of the main challenges in land degradation assessment is that a rigorous and systematic approach to addressing its complex dynamics is still missing. The development and application of operative tools at regional and ... -
Physiological and morphological short-term responses to light and temperature in two Nothofagus species of Patagonia, South America
Varela, Santiago Agustin; Fernandez, María Elena; Gyenge, Javier Enrique; Aparicio, Alejandro Gabriel; Bruzzone, Octavio Augusto; Schlichter, Tomas Miguel (2012-12)The study of plant responses to environmental stress factors is essential for management of plant systems and for anticipating their response to climate change. The main goal of this study was to determine morphological ... -
