All traps, however, have two basic elements: (1) a grid through which pollen-carrying bees must crawl to separate the pollen pellets from the bees’ legs, and (2) a container to store these pellets. Each has some feature that makes it particularly adaptable for a specific purpose. These traps vary greatly in size, appearance, and method of installation on the hive. Traps for collecting pollen pellets from legs of honey bees have been designed to trap pollen reserves. During major nectar flows, pollen trapping is unprofitable, and the grid slows down active flight, which reduces honey production. Pollen should be removed from the trap often (daily during heavy pollen flows) and cared for properly. Trapping should be done only during pollen flows of one-quarter pound per day minimum, and traps or grids should be removed at other times. Pollen should be trapped only from strong, disease-free colonies in bee-tight hives. The size, shape, and arrangement of the parts the location of the trap on the colony the method of installation and other factors can be varied to suit ii individual preferences and prevailing circumstances. This basic principle is common to all pollen traps.Ī double-layer grid with the layers separated by 3/16- to 1/4-inch and the openings offset is efficient. This grid is used with a pellet collection container that is covered by 7- or 8-mesh screen to prevent bee entry. Pollen trapping is dependent on the use of a screen or perforated metal grid of about 5-mesh per inch through which the pollen-collecting field bees are forced to enter the colony.
