Division of labor in pachycondyla striata Fr. Smith, 1858 (Hymenoptera: Formicidae: Ponerinae)

Four colonies of the ant Pachycondyla striata were used to analyze the specie behavioral repertoire. Forty-six behavioral acts were recorded in laboratory. Here, we present the record the division of labor between the castes and the temporal polyethism of monomorphic workers. The queens carried out many of the behavioral traits recorded in this work however; they performed them less frequently compared to the worker. The workers activity involved chasing and feeding on fresh insects and usingthem to nourish larvae besides laying eggs in the C-posture, an activity also performed by queens, which is similar to that of wasps of the subfamily Stenogastrinae. The young workers were involved in activities of brood care, sexuate care, and nest maintenance, and the older workers were involved in defense, exploration, and foraging. © 2012 Adolfo da Silva-Melo and Edilberto Giannotti.

El proyecto para el desarrollo de las capacidades de los paises en el area de documentacion en poblacion constituye la segunda fase de las actividades del DOCPAL (1978-1980) y tiene como objetivos centrales: a).ayudar a las instituciones comprometidas en actividades de poblacion, en alrededor de 4 paises anualmente, a mejorar sus capacidades e infraestructura; b).posibilitar a aquellos paises mejor dotados para que se constituyan en centros miembros de DOCPAL; c).mejorar, extender y continuar la entrega de servicios de nivel regional a los paises; d).mejorar y mantener los sistemas computarizados de procesamiento de la informacion. La descripcion detallada de estas actividades constituye el fundamento para la solicitud de fondos al IDRC durante el periodo senalado
