Wild Bumblebee (Bombus) Diversity and Nosema (Microsporidia: Nosematidae) Infection Levels Associated with Lowbush Blueberry (Vaccinium angustifolium) Production and Commercial Bumblebee Pollinators

Table 1

Production practices associated with the 25 sampled lowbush blueberry fields, 2009-2010. The field was given a score for each production practice based on the treatment the field received for one complete growing cycle (2 calendar years) ending with the bumblebee collection year. These practices were included in the linear model to examine field characteristics and Nosema prevalence.
