Controlling the pollinating activity of honeybees on Allium cepa in flight cages

Controlling the pollinating activity of honeybees on Allium cepa in flight cages

Sbornik Ustav Vedeckotechnickych Informaci pro Zemedelstvi, Zahradnictvi 8(4): 277-285

In a study lasting 4 years, seed yields of onions grown in cages were compared after pollination by groups of worker honeybees (100-250 g) subjected to different treatments: (A) laying queen present, (B) young brood introduced gradually, (C) extract of bee brood present, (D) treatments B and C, (E) brood added at start of trial, and emergency queen cells left in cages. For A and for B there was a significant positive relationship between rate of visiting the flowers, and seed yield.
