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 ... -
Research gaps and new insights in the evolution of Drosophila seminal fluid proteins
(Wiley, 2021-11)While the striking effects of seminal fluid proteins (SFPs) on females are fairly conserved among Diptera, most SFPs lack detectable homologues among the SFP repertoires of phylogenetically distant species. How such a ... -
Resistencia genética a las parasitosis gastrointestinales en ovinos : resultados en dos majadas Corriedale
(Asociación Argentina de Criadores de Corriedale, 2021)En la región noreste de Argentina se crían aproximadamente 2,1 millones de ovinos (14,2% del total de ovinos del país) en 37.288 unidades productivas (31,6% del total de unidades) y en la región central se crían 2,7 millones ... -
Response of the fruit fly parasitoid Diachasmimorpha longicaudata to host and host‐habitat volatile cues
(Wiley, 2012-05)Chemical information is crucial to insect parasitoids for successful host location. Here, we evaluated the innate response of Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), a fruit fly larval parasitoid, ... -

Revisando el concepto de explotación en la normativa argentina de patentes
(Universidad Externado de Colombia, 2022-06)Numerosos análisis se han dedicado a estudiar la relación entre los grados de fortaleza que puede mostrar el derecho de patente con sus efectos sobre el fenómeno de innovación. El presente trabajo busca colaborar en esa ... -
Root hydraulic conductivity and adjustments in stomatal conductance: hydraulic strategy in response to salt stress in a halotolerant species
(Oxford University Press, 2015-11)Recent advances at the molecular level are introducing a new scenario that needs to be integrated into the analysis of plant hydraulic properties. Although it is not yet clear to what extent this scenario alters the current ... -
The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings
(Nature Publishing Group, 2019-07)Previously, through a TILLING (Targeting Induced Local Lesions in Genomes) approach applied on barley chloroplast mutator (cpm) seedlings a high frequency of polymorphisms in the rpl23 gene was detected. All the polymorphisms ... -

Selective pressure against horizontally acquired prokaryotic genes as a driving force of plastid evolution
(Springer Nature, 2016-01)The plastid organelle comprises a high proportion of nucleus-encoded proteins that were acquired from different prokaryotic donors via independent horizontal gene transfers following its primary endosymbiotic origin. What ... -
Sex chromosomes in mitotic and polytene tissues of Anastrepha fraterculus (Diptera, Tephritidae) from Argentina: a review
