Behavioral and physiological changes in the passerine Agelaioides badius following the ingestion of coated seeds with imidacloprid in a 30-day experiment
(Elsevier, 2023-12)The wide use of neonicotinoid seed treatment represents a hazard for farmland birds that feed on treated seeds. This study aimed to characterize the long-term effects of the neonicotinoid imidacloprid (IMI) in the passerine ... -
Behavioral and physiological response of the passerine bird agelaioides badius to seeds coated with imidacloprid.
(Springer, 2023-09-01)Neonicotinoids are globally used insecticides, and there are increasing evidence on their negative efects on birds. This study is aimed at characterizing the behavioral and physiological efects of the neonicotinoid ... -
Comportamiento de oviposición de la avispa sierra del sauce Nematus oligospilus (Hymenoptera: Tenthredinidae): el rol de los semioquímicos en la elección de plantas hospederas
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-11)Nematus oligospilus representa una amenaza para el cultivo de sauce debido a la intensa defoliación que generan sus larvas. La colonización de las plantas hospederas se inicia cuando las hembras colocan sus huevos en las ... -
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 ... -
Expression analysis of genes putatively associated with hygienic behavior in selected stocks of Apis mellifera L. from Argentina
(2017-11)Hygienic behavior is an economically beneficial, heritable trait, which has evolved to limit the impact of honeybee pathogens. Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
First biological data of Ceresa nigripectus [Hemiptera:Membracidae], a common treehopper on alfalfa crops in Argentina
(2014-12)Alfalfa (Medicago sativa L.; Fabaceae) is essential for argentinean agricultural development, but diseases like “witches´ broom», caused by the ArAWB phytoplasma, are limiting factors for the production of this crop. ... -
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 ... -
El grooming: enemigo de la varroa
(Sociedad Argentina de Apicultores, 2021-07)Una de las enfermedades que mayores pérdidas ocasiona a la industria apícola es la Varroosis, causada por el ácaro Varroa destructor. La selección de colonias por el comportamiento de grooming puede ser una respuesta a ... -
Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
(Wiley, 2013-12)Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ... -
Individual precocity, temporal persistence, and task-specialization of hygienic bees from selected colonies of apis mellifera
(2016)Hygienic behaviour is a complex trait that gives Apis mellifera L. resistance against brood diseases. Variability in the expression of hygienic behaviour is evidenced at the colonylevel and is explained by the proportion ...
