Objective and Methodology: We explored whether ... -
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. Methoprene is a sesquiterpene with some effects that are analogous to those of JH. Treatments with ... -
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 ... -
