===Pears===

Like apples, [[pear]]s are self-incompatible and need to attract insects in order to be pollinated and produce fruit.<ref name="Abrol" /> One notable difference from apples is that pear blossoms are much less attractive to honeybees due to their pale coloring and light odor. Bees may abandon the pear blossoms to visit dandelions or a nearby apple orchard. The majority of pollinators of pear trees are [[honey bee]]s, although pears are also visited by [[blow flies]] and [[hoverfly|hoverflies]].<ref name="Abrol" /> In some areas, such as the [[Emilia-Romagna]] area of Italy, honeybees could not be used to pollinate pears due to the spread of [[fireblight]] in the 1990s, and ''[[Osmia cornuta]]'' were used as pollinators instead.<ref>{{cite journal |title=Osmia cornuta (Hymenoptera, Megachilidae) as a pollinator of pear (Pyrus communis): fruit- and seed-set |journal=Apidologie |year=2003 |last1=Maccagnani |first1=Bettina |last2=Ladurner |first2=Edith |last3=Santi |first3=Fabrizio |last4=Burgio |first4=Giovanni |volume=34 |issue=3 |pages=207–216 |doi=10.1051/apido:2003009 |url=https://www.apidologie.org/articles/apido/pdf/2003/03/M3209.pdf |accessdate=2021-08-27 }}</ref> A way to combat the low attraction of honey bees to pear blossoms is to use bee attractants to entice the bees to pollinate the flowers.Bee attractants may include [[List of honey bee pheromones|pheromones]] that mimic the brood pheromone or the juvenile pheromone, or other attractants.{{cn|date=September 2021}} There are also other methods for attracting honey bees to pear blossoms. One is [[saturation pollination]], that is to stock so many bees that all area blossoms are worked regardless of the attractiveness to the bees. Another method is to delay the movement of the beehives into the orchards until there is about 30 percent bloom. The bees are moved into the orchard during the night and will usually visit the pear blossoms for a few hours until they discover the richer nectar sources. The recommended number of hives per acre is one.
