Associative learning of visual cues in the fruit fly parasitoid Diachasmimorpha longicaudata : temporal dynamics and potential consequences on females' fitness
(Wiley, 2024-01)Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) is a generalist larval-prepupal parasitoid of true fruit flies (Diptera: Tephritidae). During host-seeking, females use visual information to locate the ... -
Comportamiento productivo de corderas de diferente genotipo bajo un sistema de engorda intensivo
(Instituto de Investigación Agropecuaria de Panamá, 2018)El objetivo fue evaluar el efecto del genotipo de las corderas sobre la finalización en corral en las condiciones del noroeste de la provincia de Corrientes, Argentina. El experimento se realizó en la Estación Experimental ... -
Differences in sperm storage and remating propensity between adult females of two morphotypes of the Anastrepha fraterculus (Diptera: Tephritidae) cryptic species complex
(Cambridge University Press, 2014-06)The South American fruit fly, Anastrepha fraterculus, is a complex of cryptic species composed of at least seven morphotypes. Some of them, such as the Peruvian and Brazilian 1 morphotypes (which include Argentinean ... -
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
(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 ... -
Host discrimination in the fruit fly parasitoid Diachasmimorpha longicaudata : evidence from virgin female behaviour and egg distribution patterns
(Cambridge University Press, 2021-04)Many parasitoid species discriminate already parasitized hosts, thus avoiding larval competition. However, females incur in superparasitism under certain circumstances. Superparasitism is commonly observed in the artificial ... -
Infestation of fruit by conspecific and heterospecific females deters oviposition in two Tephritidae fruit fly species
(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 ... -
Mate choice confers direct benefits to females of Anastrepha fraterculus (Diptera: Tephritidae)
(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 ... -
Mating-induced changes in responses of female Queensland fruit fly to male pheromones and fruit : a mechanism for mating-induced sexual inhibition
(Elsevier, 2021-03)In order to reproduce, female tephritid fruit flies need both mates for fertilization and fruit for oviposition. Virgin females are prone to mating and approach males, attracted by their pheromones. Mated females, however, ... -
Producción ovina: Revisación de hembras
(EEA Santa Cruz, INTA, 2011-12-01)La revisación de hembras es una práctica más a realizar en los es tablecimientos ganaderos dedicados a la producción ovina. Esto permite descartar aquellas madres que no son aptas para cría, teniendo en cuenta que se deben ... -
Remating behavior in Anastrepha fraterculus (Diptera: Tephritidae) females is affected by male juvenile hormone analog treatment but not by male sterilization
(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 ...
