Welcome to the Los Angeles County Beekeepers Association!

For over 130 years the Los Angeles County Beekeepers Association has been serving the Los Angeles Beekeeping Community. Our group membership is composed of commercial and small scale beekeepers, bee hobbyists, and bee enthusiasts. So whether you came upon our site by design or just 'happened' to find us - welcome! Our primary purpose is the care and welfare of the honeybee. We achieve this through education of ourselves and the general public, supporting honeybee research, and practicing responsible beekeeping in an urban environment. 

"The bee is more honored than other animals, not because she labors, but because she labors for others."  Saint John Chrysostom

(Note from LACBA: "Through our volunteer efforts at the Bee Booth at the LA County Fair the Los Angeles County Beekeepers Association supports research through Project Apis m. Take a few minutes and vote for Samuel Ramsey @" Note from Project Apis m.: "Thank you for your support! This project alone has pretty big implications for our understanding of Varroa mites- beekeeper enemy #1!)

Project Apis m. funded this important project, please vote and help Samuel Ramsey win this contest for his great work!

"Vote for me! This April I won a national competition where you're judged on how well you can present your entire Doctoral Thesis in 3 minutes (called the 3MT). I was told that I would have the distinct honor of representing the University of Maryland and, more broadly, the US in the International Competition in October! Well, October kind of snuck up on me here in Thailand!!! A big part of that competition started on Sunday: "The People's Choice Vote" and apparently my video is doing pretty well!! The University of Maryland has been really excited about it! They think I've got a shot at winning the International round and they want me to take home the People's Choice Title too! The only problem is that it's kind of difficult for me to rally the troops and get the word out while I'm in another time zone 8,431 miles away from home (approximately). So how about this: I'll rally the troops here at Chiang Mai University (after all, this project is the whole reason why I'm here); could you guys help me rock the vote in the ole US of A?"

Link Between Brain Connections And Cleverness In Bees Could Shed Light On Differences In Human Intelligence    Associated Press October 3, 2017

  • Scientists looked at type of neural connection known as 'synaptic complexes'
  • Bees that had more of these in visual area of brain region had better memories
  • The same bees were also quicker to learn new tasks, researchers discovered
  • It is the first study to suggest a link between the number of neural connections in the brain and how well an individual does on a cognitive task

A study of what makes some bumblebees brighter than others could shed light on differences in human intelligence, scientists believe.

Researchers looked at the brains of bees trained to perform different tasks and found a link between nerve cell connections and cleverness.

Bees with more synaptic connections in a specific part of their brains associated with vision had better memories and learned faster than those with fewer connections.

A study of what makes some bees brighter than others could shed light on differences in human intelligence, scientists believe

Dr Clint Perry, a member of the team from Queen Mary, University of London, said: 'Our findings are the first to suggest a strong correlation between the number of neural connections in the brain and how well an individual does on a cognitive task.

'However, at this stage we cannot show a causative link between the two.

'Our results should provide new avenues for understanding the neural basis of cognition in all animals, including humans.'

The bees were taught to discriminate between 10 differently coloured artificial flowers, half of which contained tasty sugar water and half a bitter quinine solution.

Two days later the bees were tested on how well they remembered which colours were rewarding and which were not.

Then an imaging technique called confocal microscopy was used to look deep into the brains of the bees in areas known to be responsible for visual learning and memory.

Researchers looked at the brains of bees trained to perform different tasks and found a link between nerve cell connections and cleverness.

They found that bees with a higher density of neural connections called synaptic complexes within the visual association brain region were better at remembering the colours.

Further experiments showed that bees which were quicker to learn - shown by taking fewer landings to find the right flowers - also had a higher density of synaptic complexes in the same brain region.

The findings appear in the journal Proceedings of the Royal Society B.

Queen Mary Phd student and lead author Li Li said: 'For the first time, we have shown that visual learning can increase the density of nerve connections in this area of the brain and that an enriched environment, where bees are exposed to many colours without learning anything from them, can also affect the synaptic organisation in the brain.'

A different study by Queen Mary University of London found the insects, given a selection of balls, cleverly went for the closest even after watching demonstrator bees which always chose the furthest away. 

Scientists placed bees on a platform.

Using either a live or plastic bee, they were shown how to move the ball into the trap door in the centre of the pitch.

The bees observed the technique and then copied it themselves.

Each time they pushed a ball into the trap door they were rewarded with sugar.

'Varroa Destructor Virus-1: It’s Here…'

By Karen Rennich  October 10, 2017

One of the best things about working in research is that it never fails to surprise – for good or for bad. And occasionally, it is not until much later that the surprise comes. In this case, the “surprise” arrived in the form of another Varroa-vectored, RNA virus, Varroa Destructor Virus-1, or VDV1.

Our University of Maryland lab has been leading the APHIS National Honey Bee Pest and Pathogen survey since 2010. During those years, we have processed thousands of samples from across most states for nosema spore load, Varroa load, pesticides, and viruses with the primary goal to survey whether exotics, not known to be in the US, are here or not. Secondarily, but almost as importantly, we also use the survey results to establish a nationwide honey bee health baseline. It cannot be overstated how important that baseline is, nor how vital archiving all of those samples are. In the case of viral samples, they are archived in a large -80C freezer at the USDA-ARS Beltsville Lab just down the road from us.

Dr. Eugene Ryabov, working at USDA-ARS with Dr. Jay Evans, decided to take a look into our archive freezer with the intent of re-processing those archived samples for VDV1. And we are glad that he did.  After doing a sweep of 2016 samples, he found VDV1 in >64% of all samples, making it just less prevalent and second only to Deformed Wing Virus (currently found in ~90% of all colonies). Reaching further back into that freezer, Dr. Ryabov found that only 2 colonies were positive from our 2010 survey samples – 1 in Indiana and 1 in Pennsylvania, and that temporal snapshot [below] shows the spread of this virus in just 6 years.


VDV1 is a species of RNA viruses under the genus iflavirus. Other iflaviruses include Sacbrood virus, Slow Bee Paralysis virus and its closest relative, Deformed Wing virus. Because we have methodically stored all historic samples, it will be possible, looking at the variants of this virus in the US and the world, to possibly help resolve how and when this virus arrived on our shores.  It is important to note that this virus is also present in Hawaii (the Big Island) so it has already migrated beyond the lower 48 states.

In addition to field samples, the APHIS National Survey also asks beekeepers to report colony loss numbers for the 3 months prior to being sampled. Using those losses, it may be possible to correlate those losses now with VDV1 infections and/or the levels of the virus present. This finding, and the further research it demands, provides a unique window into the forensics of this infection.

Additional information about this virus, the details used to screen for it and the possible risks to US honey bee colonies will be published in “Ryabov, E.V., Childers, A.K., Chen, Y., Madella, S., Nessa, A., vanEngelsdorp, D., Evans, J.D. (2017) Recent spread of Varroa destructor virus-1, a honey bee pathogen, in the United States. (Submitted)”.

The notice below was sent to all members of the Apiary Inspectors of America (AIA) and American Association of Professional Apiculturists (AAPA) on October 2nd.

Presence of Varroa destructor virus in the U.S.

Using RNA sequencing methods, the honey bee virus Varroa destructor virus-1 (VDV1, also known as Deformed wing virus strain B) was discovered in US honey bee samples by Dr. Eugene Ryabov, while working in the USDA-ARS Bee Research Laboratory (BRL) under the supervision of Drs. Jay Evans and Judy Chen. With guidance from the Bee Informed Partnership (University of Maryland, Dr. Dennis vanEngelsdorp) and USDA-APHIS (Dr. Robyn Rose), the BRL screened an extensive set of research samples along with U.S. bee samples collected during the USDA-APHIS National Honey Bee Disease survey.  This screening confirmed that VDV was widespread in the US in 2016 and far less common in 2010. Thanks to stored samples from the National Honey Bee Disease survey, it will now be possible to track the spread of this virus in the US and guide work for virus control in order to assure the good health of honey bees and maintain them as the primary pollinator of agricultural crops. There is no indication that VDV1 is significantly more virulent than DWV in US honey bees, and the advice to reduce levels of Varroa mites remains the same for both viruses. We are seeking to inform colleagues of this discovery primarily since VDV1 is not detectable using current genetic markers for DWV, and therefore laboratory methods will need to be tailored to detect this virus. Those involved with the National Honey Bee Disease Survey will notice that VDV1 is now a reported agent in this survey.
