What's in the Works?

FEEDING LEAFCUTTER BEES

Thanks to the hard work of Dr. Danica Baines at Agriculture and Agri-food Canada in Lethbridge, we now understand that water, sugar, and protein, play an important roll in the health and longevity of alfalfa leafcutter bees. Lab trials show, that without access to water, 50% of female ALCBs die within the first 24 hours of hatching, and 50% of male ALCBs within the first 72 hours.

Alfalfa Leafcutter Bees

Dr. Shelley Hoover has been continuing her researching into the detections of viruses in alfalfa leafcutter bees in southern Alberta. Notably they have detected deformed wing virus (DWV), acute bee paralysis virus (ABPV), and sacbrood virus (SBV) in adult bees, and SBV and ABPV in cocoons.

ALFALFA SEED RESPONSE TO PLANT GROWTH REGULATORS

Alfalfa Seed production is limited by environmental factors which cause excessive vegetative growth and limits seed set. Plant growth regulators could control that growth. With the help of the University of the Fraser Valley (UFV), ASCA is now exploring the effects of several PGRs. The desired effects of these trials would include Shortening internodes, setting flowers, and improving seed yield.

Alfalfa Weevil pesticide efficacy TRIAL

Control options for alfalfa weevil are quite limited so ASCA has commissioned a series of trials available chemical control options.

Alternatives to Paraformeldehyde

This project began in 2011, with funding contributions from ACIDF and in agreement with Neova Technologies Inc. It investigated the impact of a lysozyme in controlling chalkbrood in the leafcutter bee system.
