Claves olfativas implicadas en la orientación del parasitoide Diachasmimorpha longicaudata hacia sus hospedadores
Devescovi, Francisco; Bachmann, Guillermo Enrique; Nussenbaum, Ana Laura; Fernández, Patricia; Segura, Diego Fernando (Sociedad Entomológica del Perú, 2022-11)Objetivos: Evaluar el comportamiento de anemotaxis de Diachasmimorpha longicaudata hacia fuentes con presencia potencial de hospedadores. Identificar compuestos orgánicos volátiles provenientes de dichas fuentes que actúen ... -
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 ... -
Direct and indirect host-related volatile compounds attract a fruit fly parasitoid, Diachasmimorpha longicaudata
Devescovi, Francisco; Fernández, Patricia; Bachmann, Guillermo Enrique; Nussenbaum, Ana Laura; Segura, Diego Fernando (Wiley, 2024-02)Fruit fly pests (Diptera: Tephritidae) are a serious problem for fruit production and for local and international trade. Biological control is increasingly included as a pest control tool within integrated pest management ... -

Pores size distribution and pores volume density of mollisols and vertisols under different cropping intensity managements with no - tillage
Behrends Kraemer, Filipe; Castiglioni, Mario Guillermo; Morras, Héctor José María; Fernández, Patricia; Alvarez, Carina (Elsevier, 2021-09-15)In the Argentina Pampas, one of the most extensive agricultural areas in the temperate fringe of southern hemisphere, soil health is jeopardized mostly by the decline of physical and biological properties due to soil ... -
Soil structure and glyphosate fate under no-till manangement in the pampa region. II. Glyphosate and AMPA persistence and spatial distribution in the long-term. A conceptual model
Morras, Héctor José María; Behrends Kraemer, Filipe; Sainz, Daiana Soledad; Fernández, Patricia; Chagas, Celio Ignacio (Elsevier, 2022-07-14)Glyphosate and AMPA were measured in a no-tilled (NT) soil and in the runoff resulting from the rain simulation carried out after 270 days of the application of the herbicide. Glyphosate concentration was in low values in ... -
Unravelling chemical cues used by Diachasmimorpha longicaudata (Hymenoptera: Braconidae ) during host search
Devescovi, Francisco; Fernández, Patricia; Bachmann, Guillermo Enrique; Nussenbaum, Ana Laura; Segura, Diego Fernando (FAO-IAEA, 2022-11)Parasitoid wasps are attracted to their hosts using associated volatile compounds. In an static air olfactometer, it was shown that Diachasmimorpha longicaudata females oriented towards oranges with direct or indirect signs ...
