These F1 hybrids are usually created by means of controlled pollination, sometimes by hand pollination. For annual plants such as tomato and maize, F1 hybrids must be produced each season. For mass production of F1 hybrids with uniform phenotype, the parent plants must have predictable genetic effects on the offspring.
This has led to higher expenses for farmers from the east to the west coast of the United States and Canada to help pollinate almonds, cucumbers and certain seed plants. [10] One of the most common plants that are assisted by buzz pollination is the tomato (Solanum lycopersicum). In greenhouses worldwide, up to 50 bumblebee colonies are used ...

On several measures, including fruit weight, height, minimum and maximum diameter, grade, and seed count, bee-pollinated fruits are of significantly higher quality. [17]
