Both Volatiles and Cuticular Plant Compounds Determine Oviposition of the Willow Sawfly Nematus oligospilus on Leaves of Salix spp. (Salicaceae)
Braccini, Celina Laura; Vega, Andrea Susana; Coll Araoz, Maria Victoria; Teal, Peter E.; Cerrillo, Teresa; Zavala, Jorge Alberto; Fernandez, Patricia (Springer, 2015-11)Plant volatile organic compounds play a role in selection of host plants by herbivorous insects. Once the insect reaches the plant, contact cues determine host acceptance. Although the willow sawfly Nematus oligospilus ... -
Communication interference in sympatrically occurring moth species
Juárez, María Laura; Ruiz, María Josefina; Fernandez, Patricia Carina; Goane, Lucía; Villagrán, María Elvira; Arce, Osvaldo Ernesto Antonio; Armiñana, Arturo; Páez Jerez, Paula Gabriela; de la Vega, Marcelo Horacio; Vera, María Teresa; Groot, A.T. (Wiley, 2016-01)In moth species, females emit a species‐specific sex pheromone that is perceived over long distance by conspecific males. The species‐specificity in the chemical communication channel is achieved by a combination of unique ... -
Comportamiento de oviposición de la avispa sierra del sauce Nematus oligospilus (Hymenoptera: Tenthredinidae): el rol de los semioquímicos en la elección de plantas hospederas
Braccini, Celina Laura (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-11)Nematus oligospilus representa una amenaza para el cultivo de sauce debido a la intensa defoliación que generan sus larvas. La colonización de las plantas hospederas se inicia cuando las hembras colocan sus huevos en las ... -
Evaluating mating compatibility within fruit fly cryptic species complexes and the potential role of sex pheromones in pre-mating isolation
Juárez, María Laura; Devescovi, Francisco; Břízová, Radka; Bachmann, Guillermo Enrique; Segura, Diego Fernando; Kalinová, Blanka; Fernandez, Patricia; Ruiz, María Josefina; Yang, Jianquan; Teal, Peter E. A.; Caceres, Carlos; Vreysen, Marc J. B.; Hendrichs, Jorge; Vera, María Teresa (Pensoft Publishers, 2015-11)The study of sexual behavior and the identification of the signals involved in mate recognition between con-specifics are key components that can shed some light, as part of an integrative taxonomic approach, in delimitating ... -
Heptyl butyrate, a putative pheromone involved in social communication of Vespula germanica wasps
Buteler, Micaela; Fernandez, Patricia; Stadler, Teodoro; Weaver, David K.; Yossen, Belen; Lozada, Mariana (2018-02)Greater knowledge on the social communication of invasive Vespula germanica wasps is needed to fully understand their foraging behavior. This is particularly valuable considering that poison baiting is currently the only ... -
Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
Braccini, Celina Laura; Vega, Andrea Susana; Chludil, Hugo Daniel; Leicach, Silvia Rosa; Fernandez, Patricia (Wiley, 2013-12)Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ... -
Insectos plaga asociados a Salicáceas: herramientas de la ecología aplicadas al manejo
Fernandez, Patricia (Ministerio de Agroindustria. Unidad para el Cambio Rural, UCAR., 2016)En la Argentina, el humedal de mayor importancia y extensión es el Delta del Paraná, que cubre una superficie aproximada de 17.500 km2. El río Paraná en su curso une áreas subtropicales y templadas, característica única ... -
Male Sexual Behavior and Pheromone Emission Is Enhanced by Exposure to Guava Fruit Volatiles in Anastrepha fraterculus
Bachmann, Guillermo Enrique; Segura, Diego Fernando; Devescovi, Francisco; Juárez, María Laura; Ruiz, María Josefina; Vera, María Teresa; Cladera, Jorge Luis; Teal, Peter E.A.; Fernandez, Patricia Carina (Plos One, 2015-04)Background: Plant chemicals can affect reproductive strategies of tephritid fruit flies by influencing sex pheromone communication and increasing male mating competitiveness. Objective and Methodology: We explored whether ... -
Mate choice confers direct benefits to females of Anastrepha fraterculus (Diptera: Tephritidae)
Bachmann, Guillermo Enrique; Devescovi, Francisco; Nussenbaum, Ana Laura; Milla, Fabian Horacio; Shelly, Todd E.; Cladera, Jorge Luis; Fernandez, Patricia; Vera, María Teresa; Segura, Diego Fernando (Public Library of Science, 2019-06)Exposure to plant compounds and analogues of juvenile hormone (JH) increase male mating success in several species of tephritid fruit flies. Most of these species exhibit a lek mating system, characterized by active female ... -
Plant chemicals and the sexual behavior of male tephritid fruit flies
Segura, Diego Fernando; Belliard, Silvina Ahnahi; Vera, María Teresa; Bachmann, Guillermo Enrique; Ruiz, María Josefina; Jofre-Barud, Flavia; Fernandez, Patricia Carina; Lopez, M. Liza; Shelly, Todd E. (Oxford University Press, 2018-09)Plant compounds affect insects in many different ways. In addition to being a food source, plants also contain secondary metabolites that may have positive and negative impacts on insects. The influence of these compounds ... -
Plant‐based compounds with potential as push‐pull stimuli to manage behavior of leaf‐cutting ants
Perri, Daiana; Gorosito, Norma; Fernandez, Patricia; Buteler, Micaela (2017-05)Leaf‐cutting ants are a serious pest of young forestry plantations. Currently, the main control method is the use of broad‐spectrum insecticides, which have a negative effect on non‐target organisms and the environment. ... -
Push‐pull to manage leaf‐cutting ants: an effective strategy in forestry plantations
Perri, Daiana; Gorosito, Norma; Schilman, Pablo Ernesto; Casaubon, Edgardo; Dávila, Camila; Fernandez, Patricia (Wiley, 2020-08)BACKGROUND: Leaf‐cutting ants (LCAs) are amongst the most important forestry pests in South America. Currently, their control is carried out almost exclusively through the application of toxic baits of restricted use. Here ... -
