Musa velutina is a plant considered a biological invasion in three different areas of Costa Rica. One feature that has facilitated its invasion is the utility that it gives humans such as ornamental decor, as well as their physiological characteristics. This study was conducted in a patch of secondary forest in the district of Los Angeles in San Ramon, Costa Rica. Plant characteristics were analyzed and found to have almost doubled the amount of seeds per fruit in comparison to native species of M. velutina found in India. We also present the analysis of three capture techniques (direct observation, photo trapping and mist nets) used to determine the predators of M. velutina. It was possible to determine the existence of six predatory species, of which the Agouti was observed to have the highest number of catches. We recommend using these methods to further investigate other possible predators that can be found in differing areas where M. velutina is considered an invasive species. Further research is needed to understand how to control this highly invasive plant species found in Costa Rica.
