“ #Mites & #spiders are #arachnids and they eat each other, they also have toxins in their #venom that target each other. Spider venom #peptides "organic" way of killing mites doesn't accumulate in the food chain; doesn't kill the farmer or the beekeeper or any pets — it's selective to the #varroa mite," Dr Herzig said.

Women Work to Save #NativeBees of #Mexico
A happy story about #bees, #BeeConservation, and empowering women in Mexico.
Mar 5, 2014
Excerpt: "Spaniards introduced European #honeybees to Central America around 1620, and they are now well established. European honey bees (and their Africanized form) do compete with gentle #NativeBee species for pollen and nectar on flowers. #MeliponaBeecheii is a #ForestBee, so if they could find flowering trees and shrubs, competition with honey bees might not be a problem. Alas, #Yucatan is heavily logged.
"The Yucatan peninsula sits right in the path of a lot of big storms; quite a few hurricanes, floods, and droughts have caused beekeepers to lose all or most of their hives. Native stingless bees are quite sensitive to #pesticides, so that isn't helping either."

The East hive. This would technically be the oldest hive since the OG queen moved here with a split, or maybe after I caught a queen wandering around after the split which I suspect was the old queen since I probably split them days before they would have swarmed or she couldn't fly good enough to swarm.. whatever, she was here and generally I'd say it's been the best hive but a bit swarmy. Lots of drones in this photo.
5/5 🏁
-
The White hive. Not much to say about it, I think it swarmed twice or more last year so I suppose it doesn't really have much character.
-
The Center hive. This hive always has lots of bees, and swarmed once last year so maybe the slight meanness of some bees went with that queen. It was like 1 of 100 bees would just hit you and sting you, no warning, when checking them.
-
The Green hive. This is the part of the split with the queen from the East hive. It's activity is picking up every day as more foragers take flight. They have a green 4 leaf clover and a water trough to help ID the hive and for other bees to see sooner it's not their hive. I noticed a lot of drift from other hives landing or almost landing before realizing it wasn't their hive.
-
The West hive. These bees seem to be smaller. They could just be young bees but I've seen the small ones bringing in pollen. They seem healthy and didn't have any issues over the winter. This was a swarm caught July 17 last year and combined here since this box had swarmed and I probably cleared out it's queen cell when checking things.

Looks like good pollination on the apricot tree even though I'll probably remove all but a few if they set.

We have all heard about the devastation caused by Varroa mites. Thankfully, there is now something you can do to help our honey bees.
Australian National University's Research School of Biology has started gathering data on bee populations, and they'll supply materials if you can spare a sunny afternoon to collect some bees.

Planetary electromagnetic pollution: it is time to assess its impact
by Priyanka Bandara and David O Carpenter
Published December, 2018
"As the #PlanetaryHealthAlliance moves forward after a productive second annual meeting, a discussion on the rapid global proliferation of artificial #electromagnetic fields would now be apt. The most notable is the blanket of radiofrequency electromagnetic radiation, largely microwave radiation generated for wireless communication and surveillance technologies, as mounting scientific evidence suggests that prolonged exposure to radiofrequency electromagnetic radiation has serious biological and health effects. However, public exposure regulations in most countries continue to be based on the guidelines of the International Commission on Non-Ionizing Radiation Protection and Institute of Electrical and Electronics Engineers, which were established in the 1990s on the belief that only acute thermal effects are hazardous.
"Prevention of tissue heating by radiofrequency electromagnetic radiation is now proven to be ineffective in preventing biochemical and physiological interference. For example, acute non-thermal exposure has been shown to alter human brain metabolism by NIH scientists, electrical activity in the #brain, and systemic immune responses.
Chronic exposure has been associated with increased oxidative stress and #DNADamage, and cancer risk."Laboratory studies, including large rodent studies by the US National Toxicology Program and Ramazzini Institute of Italy, confirm these biological and health effects in vivo. As we address the threats to human health from the changing environmental conditions due to human activity, the increasing exposure to artificial electromagnetic radiation needs to be included in this discussion.
"Due to the exponential increase in the use of wireless personal communication devices (eg, mobile or cordless phones and WiFi or Bluetooth-enabled devices) and the infrastructure facilitating them, levels of exposure to radiofrequency electromagnetic radiation around the 1 GHz frequency band, which is mostly used for modern wireless communications, have increased from extremely low natural levels by about 1018 times. Radiofrequency electromagnetic radiation is also used for #radar, security scanners, #SmartMeters, and medical equipment (#MRI, diathermy, and #radiofrequency ablation). It is plausibly the most rapidly increasing #anthropogenic #environmental exposure since the mid-20th century, and levels will surge considerably again, as technologies like the Internet of Things and 5G add millions more radiofrequency transmitters around us.
"Unprecedented human exposure to radiofrequency electromagnetic radiation from conception until death has been occurring in the past two decades. Evidence of its effects on the #CNS, including altered #neurodevelopment and increased risk of some #neurodegenerative diseases, is a major concern considering the steady increase in their incidence. Evidence exists for an association between neurodevelopmental or behavioural disorders in children and exposure to wireless devices, and experimental evidence, such as the Yale finding, shows that prenatal exposure could cause structural and functional changes in the brain associated with #ADHD-like behaviour. These findings deserve urgent attention.
"At the Oceania Radiofrequency Scientific Advisory Association, an independent scientific organisation, volunteering scientists have constructed the world's largest categorised online database of peer-reviewed studies on radiofrequency electromagnetic radiation and other man-made electromagnetic fields of lower frequencies. A recent evaluation of 2266 studies (including in-vitro and in-vivo studies in human, animal, and plant experimental systems and population studies) found that most studies (n=1546, 68·2%) have demonstrated significant biological or health effects associated with exposure to anthropogenic electromagnetic fields. We have published our preliminary data on radiofrequency electromagnetic radiation, which shows that 89% (216 of 242) of experimental studies that investigated oxidative stress endpoints showed significant effects.
This weight of scientific evidence refutes the prominent claim that the deployment of wireless technologies poses no health risks at the currently permitted non-thermal radiofrequency exposure levels. Instead, the evidence supports the International EMF Scientist Appeal by 244 scientists from 41 countries who have published on the subject in peer-reviewed literature and collectively petitioned the WHO and the UN for immediate measures to reduce public exposure to artificial electromagnetic fields and radiation.
"Evidence also exists of the effects of radiofrequency electromagnetic radiation on #flora and #fauna. For example, the reported global reduction in #bees and other insects is plausibly linked to the increased radiofrequency electromagnetic radiation in the environment. #Honeybees are among the species that use magnetoreception, which is sensitive to anthropogenic electromagnetic fields, for navigation.
"Man-made electromagnetic fields range from extremely low frequency (associated with electricity supplies and #electrical appliances) to low, medium, high, and extremely high frequency (mostly associated with wireless communication). The potential effects of these anthropogenic electromagnetic fields on natural electromagnetic fields, such as the Schumann Resonance that controls the weather and climate, have not been properly studied. Similarly, we do not adequately understand the effects of anthropogenic radiofrequency electromagnetic radiation on other natural and man-made atmospheric components or the ionosphere. It has been widely claimed that radiofrequency electromagnetic radiation, being non-ionising radiation, does not possess enough photon energy to cause DNA damage. This has now been proven wrong experimentally.
"#RadiofrequencyElectromagneticRadiation causes DNA damage apparently through oxidative stress, similar to near-UV radiation, which was also long thought to be harmless.
"At a time when environmental health scientists tackle serious global issues such as #ClimateChange and chemical #toxicants in public health, there is an urgent need to address so-called #electrosmog. A genuine evidence-based approach to the risk assessment and regulation of anthropogenic electromagnetic fields will help the health of us all, as well as that of our planetary home. Some government health authorities have recently taken steps to reduce public exposure to radiofrequency electromagnetic radiation by regulating use of wireless devices by children and recommending preferential use of wired communication devices in general, but this ought to be a coordinated international effort.
We declare no competing interests. We thank Alasdair Philips for assistance with the figure and Victor Leach and Steve Weller for assistance with the ORSAA Database, which has enabled our overview of the scientific evidence in this area of research."https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(18)30221-3/fulltext

Today, our (@freelyflyingbee@Twitter and mine) first PhD student Brad Ohlinger successfully defended his thesis. He worked on costs and gains in honey bee foraging, and how to use the waggle dance to study these. He has won multiple awards for his talks, so it was a thoroughly enjoyable experience. We will miss him sorely, but we are also looking forward to read about his new adventures.
