Table 2. Estimated pollination services and economic benefits to each variety provided by the four pollinator guilds studied based on visitation rates and effectiveness (after 3 visits).
Pollinator | Variety | ||||||||

Proportion of Service (%) | Benefit (£M) | Proportion of Service (%) | Benefit (£M) | Proportion of Service (%) | Benefit (£M) | Proportion of Service (%) | Benefit (£M) | Total Benefit (£M) | |
Bumblebees | 21% (±13%) | £4.2 (±2.7)M | 13% (±19%) | £5.3 (±5.4)M | 15% (±17%) | £7.4 (±8.3) M | 38% (±33%) | £1.7 (±1.4)M | £18.6M (±£17.8M) |
Honeybee | 25% (±14%) | £5.1 (±2.8)M | 28% (±28%) | £2.6 (±3.6)M | 26% (±30%) | £12.7(±14.7)M | 23% (±22%) | £1.0 (±0.9)M | £21.4M (± £22M) |
Hoverflies | 0.3% (±1%) | £0.1 (±0.1)M | 2% (±5%) | £0.4 (±1.0)M | 0.4% (±1%) | £0.2 (±0.3) M | 1% (±1%) | £0.04(±0.06)M | £0.7M (±1.5M) |
Solitary bees | 54% (±21%) | £10.9 (±4.1)M | 57% (±29%) | £11.0 (±5.5)M | 58% (±39%) | £27.8 (±18.8)M | 39% (±24%) | £1.7 (±1.0)M | £51.4M (±29.4M) |
Proportion of service (%) = the average percentage contribution to total pollination services made by the taxa to the variety. Benefits (£M) = the monetary benefits, in million £ of additional production, of the pollination services provided by the taxa to that specific variety.
