Patent US 4,594,744

Bees are enpollinated by using a hive entrance modifier 10 formed as an elongated body that rests on the bottom board 52 of the hive 50 and extends over the hive entrance 51. In a bee-enpollinating position, body 10 closes hive entrance 51 except for a vent region 16 and a bee passageway substantially narrower than hive entrance 51. The bee passageway is recessed into body 10 to accommodate both incoming and outgoing bees and is formed as an inclined ramp 20 sloping downward toward hive entrance 51 from a top 13 of body 10 to bottom board 52 of hive 50. Recess 16 contains and shelters pollen 60 poured into the passageway to rest on bottom board 52 in hive entrance 51 for enpollinating both incoming and outgoing bees. This quickly disperses pollen 60 throughout the hive's bee colony so that all the enpollinated bees quickly carry pollen 60 to the blossoms they visit.
