Male sexual enhancement after methoprene treatment in Anastrepha fraterculus (Diptera: Tephritidae) : a sustained response that does not fade away after sexual maturation
Bachmann, Guillermo Enrique; Devescovi, Francisco; Nussenbaum, Ana Laura; Cladera, Jorge Luis; Fernandez, Patricia Carina; Vera, María Teresa; Teal, Peter E.A.; Segura, Diego Fernando (2017)The juvenile hormone (JH) of insects triggers physiological changes related to reproduction in adults of both sexes.

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 ... -
Microsatellite markers from the ‘South American fruit fly’ Anastrepha fraterculusa: valuable tool for population genetic analysis and SIT applications

Ongoing speciation within the Anastrepha fraterculus cryptic species complex: the case of the Andean morphotype
Devescovi, Francisco; Abraham, Solana; Roriz, Alzira K.P.; Nolazco, Norma; Castañeda, Rosario; Tadeo, Eduardo; Caceres, Carlos; Segura, Diego Fernando; Vera, María Teresa; Joachim-Bravo, Iara; Canal, Nelson; Rull Gabayet, Juan Antonio (Wiley, 2014-09)The Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) cryptic species complex is currently composed of seven taxonomically recognized morphotypes. Both, pre‐ and post‐zygotic isolation has been documented among ... -
Patterns of resource distribution among conspecific larvae in two fruit fly species : Anastrepha fraterculus and Ceratitis capitata (diptera: tephritidae)
Liendo, María Clara; Devescovi, Francisco; Boca, Rosa Teresa; Cladera, Jorge Luis; Vera, María Teresa; Segura, Diego Fernando (2016)1 Anastrepha fraterculus (Diptera: Tephritidae) and Ceratitis capitata (Diptera: Tephritidae) are fruit fly pests whose larvae are frequently found sharing the same fruit with conspecifics. Because larvae are incapable of ... -
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 ... -
Precocious sexual signalling and mating in Anastrepha fraterculus (Diptera: Tephritidae) sterile males achieved through juvenile hormone treatment and protein supplements
Liendo, María Clara; Devescovi, Francisco; Bachmann, Guillermo Enrique; Utges, María E.; Abraham, Solana; Vera, María Teresa; Lanzavecchia, Silvia Beatriz; Bouvet, Juan Pedro; Gomez Cendra, Paula V.; Hendrichs, Jorge; Teal, Peter E. A.; Cladera, Jorge Luis; Segura, Diego Fernando (Cambridge University Press, 2013-02)Sexual maturation of Anastrepha fraterculus is a long process. Methoprene (a mimic of juvenile hormone) considerably reduces the time for sexual maturation in males. However, in other Anastrepha species, this effect depends ... -
Remating behavior in Anastrepha fraterculus (Diptera: Tephritidae) females is affected by male juvenile hormone analog treatment but not by male sterilization
Abraham, Solana; Liendo, María Clara; Devescovi, Francisco; Peralta, Patricia Angelica; Yusef, Verónica; Ruiz, María Josefina; Cladera, Jorge Luis; Vera, Maria Teresa; Segura, Diego Fernando (Cambridge University Press, 2013-06)The sterile insect technique (SIT) has been proposed as an area-wide method to control the South American fruit fly, Anastrepha fraterculus (Wiedemann). This technique requires sterilization, a procedure that affects, along ... -
