EPA Registers Oxalic Acid to Combat Varroa Mites in Bees

EPA is registering a new miticide, oxalic acid, to combat the devastating effects of the Varroa mite on honey bee colonies. Oxalic acid is currently registered for this use in Canada and Europe. Recognizing beekeepers’ need for additional registered tools to combat the Varroa mite in U.S. honey bee colonies, the EPA collaborated with the U.S. Department of Agricultureon the registration.

Consistent with President Obama’s 2014 initiative on pollinator health, which instructed the EPA to expedite review of registration applications for new products targeting pests harmful to pollinators, OPP expedited the review of the application. EPA was able to expedite its evaluation in part due to a NAFTA “work share” agreement, which allowed Health Canada’s Pest Management Regulatory Agency to share their data reviews with EPA risk assessors and risk managers. Oxalic acid was registered in Canada for in-hive control of Varroa mites in 2010. EPA also had an established database of oxalic acid studies from its previous registration as an antimicrobial pesticide.

EPA used the existing data and information from PMRA, including updated reviews of toxicity, dietary exposure, environmental fate and transport, and product chemistry data. After a thorough evaluation of all the data, EPA concurred with the conclusions and registration decision made by our Canadian colleagues.

Varroa mites are parasites that feed on developing bees leading to brood mortality and reduced lifespan of worker bees. They also transmit numerous honeybee viruses. The health of a colony can be critically damaged by an infestation of Varroa mites. If left untreated, the colony will likelydie.

More information on this regulatory action can be found at in Docket ID: EPA-HQ-OPP-2015-0043.

Observation Hive for Sale

Looking for an observation hive to take with you when speaking to school groups or at environmental events? Want to attract attention to your booth at a farmer’s market? Bring an observation hive! I have a previously used observation hive for sale. It holds three, medium depth frames, giving space for brood and honey stores. A port that accommodates a mason jar for feeding sugar syrup is at one end of the hive, whereas the other end has a metal plate that can be raised to provide a bee exit directly or connection of a tube for exit via a building window. Frames are placed in the hive by opening the Plexiglas-containing side door with wooden knob. The hive also has a metal handle at the top for carrying to an event and screened ventilation holes on the sides and top. I’ve successfully used an identical observation hive for long-term placement in a school-even over winter-making the daily activities of the bees accessible to children.                                                         Contact Vincent Aloyo: 610-278-1621. $125.observation hive

Sold!    For Sale: Brand New Incubator for Use in Queen Rearing

Raising our own queens from colonies successfully surviving winter is recommended to improve our locally adapted stock. After being sealed in the finisher hive, queen cells can be moved to a temperature and humidity controlled incubator to complete their development. Finished queen cells can then be moved to a queenless hive or mating nuc a day or so before emergence. The “Hova Bator” has an adjustable thermostat with digital temperature readout. Also included is the “IncuTherm Plus™ Monitor” which provides remote temperature and humidity monitoring and has a min/max memory. Water is added as needed based on the digital hygrometer readout. The “Circulated Air Fan” assures uniform temperature throughout the incubator space.                                       Contact Vincent Aloyo: 610-278-1621. $100
