          Abstract

          Con el fin de caracterizar algunos aspectos del forrajeo en Polybia occidentalis venezuelana en la región de Montería (Córdoba), se realizaron observaciones durante 20 horas a seis nidos en tres zonas de vegetación. Se registró el número de avispas que salieron y las que retornaron al nido desde las 07:00 hasta las 18:20 horas y se identificó el alimento sólido traído al nido. El rango de forrajeo fue estimado. Altas temperaturas y humedades relativas bajas influenciaron positivamente la frecuencia de salidas de forrajeras del nido. El forrajeo por líquido constituyó el 53% de los eventos, mientras que el forrajeo por alimento es de 18,5% y el de pulpa para construcción del nido el 12,5%. Las presas estuvieron constituidas por Lepidoptera (58,5%), Diptera (20,5%), Hemiptera (6,7%), Coleoptera (2,7%) e Hymenoptera (2,1%). Spodoptera frugiperda fue la presa más frecuente; el 9,2% restante lo constituye el material no identificado. El rango de vuelo de P. occidetalis venezuelana fue aproximadamente de 50 m, resultando un área principal de forrajeo de 7854 m². En promedio una colonia capturó 72 presas al día y un adulto acarreó el 39% de su peso en cada viaje. La dieta descrita para esta especie así como su rango de forrajeo coinciden con estudios desarrollados en otras regiones y resaltan el potencial de Polybia occidentalis venezuelana en programas de control biológico en agroecosistemas del departamento de Córdoba.

          Translated abstract

          In order to characterize some aspects of foraging in Polybia occidentalis venezuelana in the region of Monteria (Cordoba), observations were made over 20 hours at six nests located in three zones of vegetation. The number of wasps departing and returning to the nest was recorded from 07:00 to 18:00 hours and the solid food brought to the nest was identified. The range of foraging was estimated. High temperatures and low relative humidities positively influenced the departure frequency of foragers from the nest. Foraging for liquid constituted 53% of the events, while foraging for food was 18.5% and pulp for nest construction was 12.8%. Prey items consisted of Lepidoptera (58.5%), Diptera (20.5%), Hemiptera (6.7%), Coleoptera (2.7%), and Hymenoptera (2.1%). Spodoptera frugiperda was the more frequent species; the remaining 9.2% constituted unidentified material. The flight range of P. occidentalis venezuelana was about 50 m, resulting in a main foraging area of 7,854 m 2. On average a colony captured 72 prey per day and an adult lifted up to 39% of its own weight on each trip. The diet described for this species, as well as the foraging range, coincide with studies conducted in other regions and highlight the potential of Polybia occidentalis venezuelana for biological control programs in agroecosystems of the Cordoba department.
