Weight (mean ± sem) of corbicular pollen (g/day) trapped throughout the avocado pollination period of colonies (N = 40) fed on marri (dashed line), jarrah (solid line), clover (dotted line) and canola (dashed and dotted line) feed sources. Colonies collected more corbicular pollen in week 1 compared to any of the other weeks during peak flowering (p < 0.0001). The amount of corbicular pollen collected in weeks 2 and 3 did not differ from each other (p = 0.328).
