Abstract

Two colonies of Trigona fulviventris were studied in Monteverde, Costa Rica in April- May, 2003. Foraging patterns were analyzed within the nest and between nests. Nest EBM showed no significant foraging change from morning to afternoon and no proportional foraging difference over the course of the study. On the other hand, nest DM showed significant change morning vs. afternoon as well as a clear proportional change along the duration of observations (p < 0.0001). There was also a difference in behavior between both nests (p = 0.004) which leads to the speculation that the timing of brood production of these two nests are not equal even though they are located in the same region and studied over the same time span.

Resumen

Dos colonias de Trigona fulviventris fueron estudiadas en Monteverde, Costa Rica en Abril-Mayo, 2003. Modelos de buscando se analizaron dentro del cada nido y entre nidos. El nido EBM mostró no significativo cambio de busca de la mañana a la tarde y no diferencia proporcional sobre el curso del estudio (chi-square = 4.16; p = 0.13). Por otro lado, el nido DM mostró cambia significativa en la mañana vs. la tarde así como un cambio proporcional claro por la duración de observaciones (chi-square = 18.9; p < 0.0001). Había también, una diferencia en la conducta entre ambos nidos (chi-square = 11.24; p = 0.004) que lleva a la especulación que el momento de la producción de la cría de estos dos nidos no es igual aunque ellos son localizados en la misma región y el mismo espacio del tiempo.
