          Abstract

          Solenopsis cf. picea, también conocida como “la negrita”, es una hormiga abundante en los sistemas cafeteros de la zona de Risaralda (Colombia), donde anida en el suelo y se encuentra tanto en cafetales de sombra como monogenéricos. Estudios realizados en campo y en laboratorio han demostrado que depreda sobre la broca del café, convirtiéndola en un organismo que podría ser implementado como control biológico. Este trabajo tuvo como objetivo estudiar algunos aspectos de su ciclo de vida, en términos de desarrollo del inmaduro y aspectos reproductivos del organismo. Se encontró que el desarrollo (reconocimiento cronológico y morfológico) de inmaduros correspondió a un promedio de 56 días. Las medidas de cápsula cefálica agruparon a los individuos en tres ínstares larvales. El promedio de la postura de huevos durante 24 horas fue significativamente mayor en colonias monoginas acompañadas de densidades altas de obreras y la fecundidad individual de las reinas disminuyó con la presencia de otras reinas en una misma colonia.

          Translated abstract

          Solenopsis cf. picea, also known as “the little black”, is an abundant ant in the coffee systems of Risaralda, Colombia, where it nests in the soil and can be found in both shaded coffee plantations and in coffee monocultures. Studies carried out in the field and laboratory have demonstrated that it predates on the coffee berry borer, making it an organism that could be implemented as a biological control. The objective of this research was to study some aspects of its life cycle, in terms of development of the immature and reproductive aspects of the organism. Results showed that immature development (chronological and morphological recognition) took an average of 56 days. The cephalic capsule measures grouped individuals into three larval instars. Mean number of eggs laid in 24 hours was significantly higher in monogynous colonies accompanied by high densities of workers, and the individual fecundity of the queens decreased with the presence of other queens in the same colony.
