In outcrossing crops like alfalfa, various bee species can contribute to pollination and gene flow in seed production fields. With the increasing use of transgenic crops, it becomes important to determine the role of these distinct pollinators on alfalfa pollination and gene flow. The current study examines the relative contribution of honeybees, three bumble bee species, and three solitary Average seed production per plant was 17.2 gm. with a range from 8.8 to 44.8 gm. The 400% range suggests a good possibility of improvement by breeding for this character. 5. Preliminary progeny tests for nectar production per flower were conducted, using polycross progenies and selfs and crosses involving high and low nectar producers. Measures of tripping at different dist~lnces from alfalfa leafcutting bee domiciles showed about 80% or more tripped flowers within 30m (100 feet). dropping to about 40% between 40-53m (130-175 feet) in one data set and averaging 44.5% near a domicile versus 2.1% at 160m (530 feet). Specifically, alfalfa is a cross-pollinated, perennial crop that requires bees to "trip" flowers to release pollen for seed production (McGregor 1976). Typically, alfalfa seed producers depend on GE alfalfa seed production and seed production for APS export markets. The basis for current isolation standards is discussed in a peer reviewed publication describing the biology of alfalfa and alfalfa production in the U.S.; a comprehensive overview of gene flow in alfalfa and procedures to mitigate gene flow (CAST, 2008). Alfalfa performs best on well-drained, relatively deep soils with a minimum rooting depth of 0.9 to 1.2 m. Limitations to rooting depth may be caused by physical or chemical factors, such as hardpans, stratified soils, or salts that restrict productivi- ty and lower yield. Poor drainage or a high water ta- ble may also limit root growth.

Approximately 200,000 alfalfa seeds are in one pound. 5. Alfalfa roots can penetrate the soil more than 15 feet deep. 6. People eat alfalfa in the form of alfalfa sprouts or in the form of ice cream and cheese. 7. Honey is often made by bees after they visit alfalfa fields. 8. Alfalfa can be cut between 3-12 times and can last up to 25 Over 600 honey beekeepers (10% of over 6000 beekeepers) and 86 alfalfa leafcutting bee producers participated (28% of over 300 producers). • selected interviews with suppliers and users of bumblebees for pollination of greenhouse and field crops. • selected participation in document review teams. How should this document be used? There are two different types of insects that produce honey in Zambia. The indigenous African honey bee (Apis melliferaspecies) produces most of the honey and beeswax for the commercial beekeeping industry. Secondly, a group of insects known as "stingless bees" (including Meliponula, Beekeeping in Zambia CIFOR 2 February 2008 Number 7 The price of bulk honey fluctuates with i
