Analysis of the gut bacterial community of wild larvae of Anastrepha fraterculus sp. 1: effect of host fruit, environment, and prominent stable associations of the genera Wolbachia, Tatumella, and Enterobacter
Salgueiro, Julieta; Nussenbaum, Ana Laura; Milla, Fabian Horacio; Asimakis, Elias D.; Goane, Lucía; Ruiz, María Josefina; Bachmann, Guillermo Enrique; Vera, María Teresa; Stathopoulou, Panagiota; Bourtzis, Kostas; Deutscher, Ania T.; Lanzavecchia, Silvia Beatriz; Tsiamis, George; Segura, Diego Fernando (Frontiers Media, 2022-03)The genus Anastrepha (Diptera Tephritidae) includes some of the most important fruit fly pests in the Americas. Here, we studied the gut bacterial community of 3rd instar larvae of Anastrepha fraterculus sp. 1 through Next ... -
Effect of Fruit Volatiles from Native Host Plants on the Sexual Performance of Anastrepha fraterculus sp. 1 Males
Bachmann, Guillermo Enrique; Belliard, Silvina Ahnahi; Devescovi, Francisco; Nussenbaum, Ana Laura; Fernández, Patricia Carina; Vera, María Teresa; Ruiz, María Josefina; Segura, Diego Fernando (MDPI, 2023-02)Anastrepha fraterculus sp.1 males are sexually stimulated by the aroma of fruit of its native host Psidium guajava (guava). Other hosts, which are exotic to A. fraterculus, do not enhance male sexual behavior. Here we ... -
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 ... -
Lemon and Schinus polygama essential oils enhance male mating success of Anastrepha fraterculus
Ruiz, María Josefina; Suárez, María L.; Jofré Barud, Flavia; Goane, Lucía; Valladares, Gabriela A.; Bachmann, Guillermo Enrique; Belliard, Silvina Ahnahi; Páez Jerez, Paula; Zamora Belli, Ana Lucía; García Méndez, F. Daniela; Segura, Diego Fernando; Lopez, María Liza; Vera, María Teresa (Wiley, 2020-11-27)The sterile insect technique (SIT) is an environmentally friendly pest control method that relies on the introduction of sterility into the pest population by the release of sterile males. Many Tephritidae fruit fly pests ... -
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 ... -
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 ... -
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 ... -
Yeast derivatives and wheat germ in the adult diet modulates fecundity in a tephritid pest
Goane, Lucía; Pereyra, P. M.; Castro, F.; Ruiz, María Josefina; Juárez, María Laura; Segura, Diego Fernando; Vera, María Teresa (Cambridge University Press, 2019-04)Anastrepha fraterculus (Wiedemann), a pest of great economic importance in South America, needs urgently to be controlled by environmentally friendly methods such as the sterile insect technique for which mass rearing of ...
