Encouraging the Bumble Bee in Washington hy CARL JOHANSEN, Associate Entomologist and ROBERT HUTT, Experimental Aide Washington State University- Pullman, Washington A small, golden-tipped bumble bee, Bombus mixtus, is the most important pollinator of cranberries in Washington. Following are sug- gestions for encouraging this species and other bumble bees: (1) Provide hives for protection from weather and natural enemies. Individual units can be constructed from % inch lumber and inside measurements should be about 6x6x6 inches. Six single units can be conveniently prepared from the following material: (a) 10 feet of 1 x 8 lumber cut into 10-inch lengths (forms '* tops and bottoms with Vz inch overhang) (b) 6V2 feet of 1 x 8 lumber cut into 6y2-inch lengths (forms ends) (c) 71/2 feet of 1 x 8 lumber cut into 71/2-inch lengths (forms sides which should be nailed inside end pieces) Several nesting units can be provided in one large box with partitions. Lengths of plastic pipe, % inch inside diameter and about 18 inches long, can be attached to the entrance hole of each nest unit by means of plastic couplings (% inch inside diameter). Pipe or hose sections with diameter as small as V2 inch are large enough for the cranberry bee and have the added value of protection from shrews. Shrews are also deterred by pipe entrances through 1 x 10 rough lumber held vertically, with or without a 6-inch square of sheet metal around the opening. Bumble bees will accept a nest entrance formed by a 2-3 inch black tube or simply a hole drilled in rough lumber. However, it is important that the op
