A better understanding ... -
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 ... -
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
Devescovi, Francisco; Liendo, María Clara; Bachmann, Guillermo Enrique; Bouvet, Juan Pedro; Milla, Fabian Horacio; Vera, María Teresa; Cladera, Jorge Luis; Segura, Diego Fernando (Wiley, 2015-08)1. The avoidance of parasitized or infested hosts, which is a common phenomenon in parasitic wasps and phytophagous insects, may act both intra- and interspecifically. Most studies on chemically-mediated avoidance of ... -
Infestation of fruit by conspecific and heterospecific females deters oviposition in two Tephritidae fruit fly species
Liendo, María Clara; Parreño, María Alejandra; Pietrek, Alejandro G.; Bouvet, Juan Pedro; Milla, Fabian Horacio; Vera, María Teresa; Cladera, Jorge Luis; Segura, Diego Fernando (Wiley, 2020-09)Tephritidae fruit fly larvae develop entirely in the host chosen by the females. To improve the fitness of their progeny, females would benefit from rejecting previously exploited hosts. Anastrepha fraterculus and Ceratitis ... -
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 ... -
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.
