Abstract

Territoriality is a competitive behavior expressed commonly throughout the animal kingdom in a wide variety of ways. To establish there is territoriality in simpler animals such as insects the practice of two specific types of behavior is a strong indicator. The first behavior is site fidelity, or the tendency of an animal to regularly return to previously occupied locations. The second behavior is the expression of aggression during encounters between two individuals in the presence of the aforementioned location. To test the presence of territoriality in a Neotropical cricket population, site fidelity was recorded as well as the response to an ‘intruder’s’ call being played in an individual’s territory. The results of these experiments confirmed the presence of territoriality in the subject, indicated by a high percentage of site fidelity and the reduced song-rate in the response call to intruder playbacks. La territorialidad es un comportamiento competitivo expresado a través del reino animal en una gran variedad de formas. Para establecer la territorialidad en animales como insectos la práctica de dos tipos específicos de comportamiento son un fuerte indicador. El primer comportamiento es fidelidad de sitio, o la tendencia de un animal a regresar constantemente a sitios ocupados previamente. El segundo comportamiento es la agresión durante encuentros entre dos individuos en un mismo sitio. Para probar la presencia de territorialidad en una población de grillos neotropicales, la fidelidad de sitio fue medida, así como la respuesta al llamado de un "intruso" sonado en el territorio de un individuo. El resultado de este experimento confirma la presencia de territorialidad en el sujeto, indicado por un alto porcentaje de fidelidad de sitio y la reducción de la tasa de canto en respuesta al llamado de un intruso.
