    • Abstract:
      Drosophila melanogaster Meigen 1830 (Diptera: Drosophilidae) es el organismo modelo por excelencia en insectos. Sin embargo, salvo algunas excepciones, los aspectos ecológicos de esta especie han sido poco estudiados. En el presente trabajo, se describe un ensayo comportamental para cuantificar la conducta olfativa de larvas de D. melanogaster en respuesta a estímulos olfativos complejos que se encuentran en los ambientes naturales, i. e.: frutos en descomposición que son hospedadores en la naturaleza. Los resultados obtenidos, utilizando este ensayo, revelaron que existe variabilidad genética intra-poblacional y plasticidad fenotípica para el carácter en una población natural del centro oeste de Argentina.

    • Abstract:
      Drosophila melanogaster Meigen 1830 (Diptera: Drosophilidae) is the quintessential insect model organism. However, with a few exceptions, ecological features of this species have been poorly investigated. In the present work we describe a behavioural assay to quantify olfactory behaviour of D. melanogaster larvae in response to complex olfactory stimuli that are present in the natural environments, i. e: rotten fruits that act as hosts in nature. Results obtained using this assay reveal that there is intra-population genetic variation and phenotypic plasticity for the character in a natural population from west-central Argentina.
