had a farm gate value of approximately $20 million. Leafcutter bee sales added approximately $3 million additional farm gate value. Extra leafcutter bees provide pollination for local hybrid canola production and are exported for alfalfa seed, blueberry, melon, vegetable seed and tree nut/fruit production in the U.S. and eastern Canada. This. Alfalfa seed production for GE sensitive export markets in the PNW is primarily pollinated by leafcutter bees. The production of non-detect GE seeds under leafcutter bee pollination will require almost six times the current NAFA best practice of a feet isolation distance. Seed production in “de facto” GE free production.
Selecting the best alfalfa varieties is one of the most important decisions producers make in devel - oping a good forage-production system. Selecting alfalfa varieties is a 5- to year investment. It is important to buy quality seed of certified varieties with high germination percentages. Planting high-File Size: KB. Alfalfa Bees Prove Their Carrot Competence By Marcia Wood. LOGAN, Utah, Aug. The domesticated honeybee may get more glory, but when it comes to pollinating carrots, one tiny alfalfa leafcutter bee can do the job of 20 of its larger, noisier, more irritable cousins, says a U.S. Department of Agriculture researcher.. Alfalfa leafcutter bees are about a quarter-inch-long, and black with bands.
Seed growers in the West, particularly in Idaho and Utah, first noticed this bee visiting alfalfa field blooms, and came to realize its value as a commercial pollinator. This bee has been re-introduced world-wide where alfalfa is grown. Karen Strickler, PhD, is a leading authority on alfalfa leafcutter bee . The Alfalfa Leafcutter Bee (Megachile rotundata) is a European species of bee that has been cultured in the United States solely for pollination purposes. As a solitary but gregarious bee species, it does not build colonies or store honey, but is a very efficient pollinator of alfalfa read more seed, carrot seed, and some other vegetables.

The behaviors of the alfalfa leaf cutter bee - seed production system under imposition of several management regimes were studied through the use of a simulation model that contains mechanisms for the following processes: 1) immature bee development and diapause; 2) immature bee mortality; 3) female bee emergence; 4) nesting tunnel selection; 5) egg-laying; 6) adult mortality; and 7) flowering and seed by: 1.
The alfalfa leafcutting bee, Megachile rotundata, is a very important pollinator of alfalfa for alfalfa seed production. This bee species was introduced to the United States from Eurasia in the late s. Wherever the bee is managed efficiently and effectively, alfalfa seed yields increase dramatically compared to pollination with honey bees or no bee.

The alfalfa leafcutting bee, Megachile rotundata F., is used extensively to pollinate alfalfa for seed production in western North America. However, it usually is not possible to sustain bee. Alfalfa Seed Production in the Western U.S. -A Commitment to Quality Shannon C. Mueller INTRODUCTION Properly timing cultural practices is the key to a successful production system.
In a typical system in California and parts of the Northwest, this would include: the leafcutter bee is extremely susceptible to pesticides. Although most. Megachile rotundata (or the alfalfa leafcutter bee) is a species native to Eurasia that was introduced into the United States after the ’s because of a drop in seed production.
This bee was brought into the US to increase pollination yields of Alfalfa for seed because honey bees are not the best pollinators of the crop. With the introduced alfalfa leafcutter bee, alfalfa seed can be produced economically wherever the bee can thrive and where growing and harvesting conditions are good for alfalfa.
The loose-cell system of leafcutter bee management was developed to manage the large populations of. OF ALFALFA LEAFCUTTER BEES Saskatchewan Alfalfa Seed Producers Association By mid-August, alfalfa leafcutter bee females begin to die off and the population working in the field gradually dec reases.

Alfalfa Leafcutter Bee Incubation Calendar - (Modified from the original SAF FarmFact publication) D.W. Goerzen, Research Scientist Alfalfa leafcutter bee cells are placed into incubation trays and the incubator temperature is set at 30o C. Count "Day 1" of incubation as the first full day at which the bee cells are at 30o calendar of incubation assumes cold storage.
Alot of alfalfa seed is produced "by accident," because managing water for alfalfa seed production is probably easier under accidental dryland conditions than under controlled irrigation. The uniqueness of alfalfa seed water management and the premium that can come from a crop of good quality seed made me think this topic deserved more attention.
The Saskatchewan Alfalfa Seed Producers Association (SASPA) is a non-profit corporation established by alfalfa seed producers in to support alfalfa seed and alfalfa leafcutting bee production in Saskatchewan. SASPA works on research and extension initiatives in the areas of alfalfa seed production and alfalfa leafcutting bee management, and is actively engaged in the promotion of alfalfa.
General Facts: Megachile Rotunda or Alfalfa Leafcutter Bee belong to the family Megachilidae and are members of the Megachile genus.
Leaf cutters are non-agressive, non- colonizing solitary bees that Pollinate alfalfa, gardens, and flowers. They are fuzzy with thin yellow/gray stripes down the abdomen and the underside.
Parasites (Pteromalus venustus) of Alfalfa Leafcutting Bees. Pteromalus venustus^ is a very small wasp that parasitizes alfalfa leafcutting bees (ALB) (Megachile rotundata) and can cause serious economic are sometimes referred to as parasites, Pteromalus, chalcid wasps, chalcidoids, or terms are not necessarily specific to P.
venustus, so context is important. Megachile rotundata, the alfalfa leafcutting bee, is a European bee that has been introduced to various regions around the world. As a solitary bee species, it does not build colonies or store honey, but is a very efficient pollinator of alfalfa, carrots, other vegetables and some e of this, farmers often use M.

Journal of the Kansas Entomological Society 69(4) suppl., (): Strickler, K. some of you guys are feeling bad about peas, lentils, etc. leaf cutter bees dropped from $/gal. to $15/gal in one year,(on the ones that we are able to sell, many will not sell).
alfalfa seed dropped from $ /lb to $ /lb in one year. hows that for a one year drop. anyone seeing any different prices out there concerning these two products. anyone thats been thinking about trying. A Model Study of the Alfalfa Leaf cutter Bee Seed Production System by Steven Bruce Stark A THESIS submitted to Oregon State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy Completed Ap Commencement June Here’s a good story in the Capital Press on the role of Alkali bees in pollinating alfalfa seed fields in the Pacific Northwest (follow link below).
A different kind of bee. Alkali bee (Ken Gray photo) I’ve been fascinated with these bees for many years now and I cover them in my Seed Production course at OSU.
Unlike the honey bee, alkali bees are native to the Pacific Northwest. The development of alfalfa leafcutter bee management arose from the need for better pollination of the alfalfa seed crop in North America. Poor pollination and inconsistent cropping was a result of insufficient numbers of native bees, and honey bees are not an efficient option because they do not adequately pollinate alfalfa.
A Better Way to Bee. I grew up in the Columbia Basin, and while I never worked on farms that grew alfalfa seed, I certainly had friends whose fathers farmed and had leafcutter bee houses in their alfalfa .Van der Stoel Pollinating provides custom leafcutter bee pollination services in Southern Alberta to hybrid canola, alfalfa seed, and milk vetch crops.
The company has considerable experience in the leafcutter bee industry, and has worked to create a standard of high customer service and pollination throughout its almost twenty years of existence.Typically for alfalfa hay production, growers are planting anywhere from 20 to 25 pounds of seed per acre, and in seed production you would plant 1 to 2 pounds of seed per acre.
In order for the seeds to grow adequately, there are certain climate conditions that are favorable.
