My lab may be on the verge of a huge breakthrough – use of brood pheromones to enable precise and rapid selection of Varroa and disease resistant bees - and Project Apis m. (PAm) provided support critical to this success. It started with a Ph.D. project related to hygiene communication. At the time, the focus of the research community seemed to be on hygienic adults – their superior sense of smell and how this enhanced perception was modulated in the honey bee brain. But what exactly was it they were smelling? We decided to find out.
New Research at Project Apis m.
Project by project, PAm helps address the bee health questions of today while helping beekeepers prepare for the future. Across the U.S. and Canada, recently funded projects are beginning on topics ranging from Varroa and viral diseases to drought-tolerant bee forage.
Eyes on Amitraz
Varroa mites are a plague to all honey bees and beekeepers in the US and most of the world, but beekeepers have limited tools available for Varroa control. One widely used tool is Amitraz/Apivar strips. Although Amitraz has been effective for almost two decades, we know from experience that using synthetic compounds puts pressure on Varroa populations and can lead to mite resistance. This happened with fluvalinate (Apistan) and Coumaphos (Checkmite) within 10-15 years of use. As we pass those landmarks using Amitraz for Varroa control, beekeepers and scientists are on the lookout for treatment efficacy and any signs of resistant mites.
Zac Lamas is the 2019 PAm-Costco Scholar. He is a PhD candidate at the University of Maryland, studying at the vanEnglesdorp Bee Lab. Zac started his career as a beekeeper and queen producer, and recently switched his focus to honey bee research. PAm recently caught up with Zac to hear more of his story. We are excited to be investing in researchers like Zac, who bring unique experience and insight to the fold of scientists that are supporting honey bee health.
The Bee Informed Partnership (BIP) and Project Apis m. (PAm) have a long history of partnership. Since 2012 PAm has deeply supported the BIP Tech Transfer Teams (TTTs), who are the “boots on the ground” to survey honey bee health, and often acting as liaisons between research, and beekeepers. Their unique position not only allows them to share research developments and management practices with commercial beekeepers, but they also understand the most current beekeeping needs and trends and can help inform researchers about what is going on in the beekeeping industry that needs to be addressed.
Commercial beekeepers who work with the Tech Transfer Teams on average lose 30% fewer colonies each year than beekeepers who do not. That is significant! Quite a few participating beekeepers have also reported saving money by working with TTTs - some very major losses have been avoided, and many beekeepers report overall improved condition of their bees as well.

The HilΩ Bee Project
Hawaii is a chain of many islands, and of the seven inhabited by people and bees, only two have Varroa mites. I know, in beekeeper minds, that quickly conjures an image of paradise and perfectly healthy booming colonies with no Varroa! Having worked with bees on all those islands since 2010, I can report with confidence that the bees on these mite-free islands fall far short of this fantasy. Although there are no Varroa, these bees are a great example of how the many years of breeding and selection have provided us with the important traits beekeepers rely on, like gentle temperament, large populations and brood nests, reduced swarm tendencies, large honey stores and winter survival. Although they were abundant and successful in Hawaii’s conditions, the bees throughout the Hawaiian Islands were not, on average, large, gentle, productive colonies. They were mostly small, mean colonies of A. mellifera mellifera, brought by ship in 1850’s, and then naturalized in the jungle without beekeeper selection or improvement. The first time I met with a beekeeper as the Hawaii state apiarist, a bee met me over 50 yards from the undisturbed colony and immediately stung me in the face! This was a hobbyist, whose colonies were captured from the jungle. He likely didn’t know any different, but his bees had traits in stark contrast to the selected stocks I was used to throughout the USA and Canada. To be fair, they were also very different than the bees kept by Hawaii’s queen producers, which were painstakingly selected and improved by breeders such as Gus Rouse at Kona Queen.

Cameron Jack Grew up watching his grandfather work 150 hives in southern Nevada. This was his gateway-bee experience. Learning and watching – being taught about honey bees. Today, Cameron is a researcher and lecturer at the University of Florida, Department of Entomology and Nematology.
Cameron received a one-year Costco/PAm fellowship award in 2016 to conduct research at the University of Florida where he is completing his graduate work. The subject of his research: Varroa. More specifically, his focus has been on breeding Varroa in vitro in the laboratory.
North Dakota is home to over half a million honey bee colonies, and is the number 1 honey producing state in the US for the past 30 years. According to the North Dakota Department of Agriculture, in 2017, North Dakota produced 33 million pounds of honey valued at over $65 million. The vast expanse of land, as far as the eye can see, offers a dense and rich clover forage, a favorite of the honey bee. It is therefore no surprise that more beekeepers want to bring their bees to the Peace Garden State each year. In contrast, corn and soybean are gaining popularity in the agricultural landscape of North Dakota, replacing some of the more traditional grain crops of the past. As a result of these two opposing landscape factors, beekeepers in North Dakota report an increase in honey bee colony density and a decrease in forage for the pollinator. Zac Browning of Browning Honey Co. warns that North Dakota is the ‘Last Best Place for Bees’.
