Figure 3

Proportion of bumblebees sampled from Maine blueberry fields showing Nosema infection as determined by light microscopy. Proportions shown by day of the year between the sampling period, 4 June–3 September, 2009-2010 (data from two years pooled). The high of 33.33% is from a day with a total catch of three bees, one of which scored positive for Nosema spp.
