Current human activities, however, threaten their populations, making it urgent to assess their abundance and genetic status. The lower effect of bumblebees in Salto's greenhouse inalthough the tendency of the performance indicators values was the same as that of the other two experiences, can be explained by environmental conditions that favored tomato production, which were better than those of the following year in the same greenhouse.
