    Las interac ciones antagónicas son comunes en las poblaciones de abejas, situación provocada por la necesidad de un recurso limitado tal como es el alimento (n éctar y polen), espacio o pareja.

    En esta tesis se evaluó la conducta de agresión de la abeja nativa Lithurgu s littoralis hacia co y heteroespecí ficos artificiales en flores de Opuntia huajuapenis . Para ello se aplicaron cuatro tratamientos en 200 flores de la cactácea, sobre las cuales se colocaron abejas artificiales que imitaron a la abeja introducida ( Apis me llifera ) y nativa , en condiciones naturales , utilizando abejas artificiales de ambas especies de abejas en grupos de dos, tres y cuatro flores...

    Antagonistic interactions are common in bee populations; this is caused by the need of a limited resource such as food (nectar and pollen), space or mate. We evaluate the aggression behavior of Lithurgus littoralis bees towards its artificial conspecifics and heterospecifics on flowers of Opuntia huajuapenis. For this purpose an experiment with four treatments with 50 flowers each was conducted. On which we placed artificial bees who imitated the native and exotic bee. Subsequently we assessed whether aggressive behavior depends on the amount of resources. For these three experiments in groups of two, three and four flowers with four treatments each one and using artificial bees of L. littoralis and Apis mellifera was made. The results suggest that in the first experiment, the native bee is very aggressive towards its conspecifics located in the flowers of O. huajupensis and that the intensity of aggression bee depends on gender. While the second group of experiments, we recorded the number of flowers and quantity of nectar and pollen of this species of cactus does not influence in the aggression behavior of L. littoralis. In these experiments, the native bee is more aggressive with A. mellifera. We discuss how the aggression behavior of L. littoralis is safeguarding and securing resources regardless of the number of these.
