WHAT THIS SITE IS ABOUT 澳洲5历史开奖记录查询



Firstly, I give permission for use of all material on this website for
educational purposes so long as it is attributed to
澳洲幸运5开奖结果历史查询#澳洲幸运5开奖结果历史开奖记录图片#百度澳洲幸运五开奖结果 ScientificBeekeeping.

This is not a “How You Should Keep Bees” site; rather, I’m a proponent of
“Whatever Works for You” beekeeping.  I’m a “data over dogma” guy, and I implore
my readers to correct me on any information at this website that is out of date
or not supported by evidence.

“It’s what you know for sure that keeps you from learning.”

And I’m all about learning.  I’d like to make it perfectly clear that I do not
consider myself to be the final arbiter on any matter!  In investigating many of
these controversial subjects, my brain feels like a GPS unit, repeatedly saying,
“Recalculating” and sometimes even “Turn around when possible.”   This is why I
take care to hold no positions, and appreciate being intelligently challenged on
any point.   If something comes to my attention that makes me rethink or correct
anything I’ve written, I am more than happy to rebut myself on these pages.

I’ve visited beekeepers in many countries, and realize that there are as many
ways to keep bees as there are beekeepers.  The bees don’t care whether you are
a commercial or hobby beekeeper, nor whether your personal preference is
Langstroth, Warre, top-bar, small cell, foundationless, “natural” or
conventional beekeeping–the same biology applies to all.   My goal is to
provide any and all beekeepers with a resource of readable and straightforward
information on how to practice good bee husbandry, and  to exercise
environmental and community responsibility.

This site is more or less a record of my learning process as I apply my formal
training as a biologist to the practice of running my ever-evolving commercial
beekeeping operation in California.  I have no interest in offering advice
(there are plenty of beekeepers more than eager to do that).  Rather, what I do
offer is evidence-based and scientifically-verified explanations of the
biological processes occurring in the hive, as well as the effects of various
management options.  I then leave it to each beekeeper to use that information
in order to make their own better-informed practical management decisions.   

In this “post-truth, information overload era” novice beekeepers can be
overwhelmed by an internet and popular press chock full of conflicting strong
opinions and questionable advice.  If you are a beginning beekeeper looking for
basic information, or an experienced beekeeper looking for a summary of mite
treatment options, I suggest that you go directly to Basic Beekeeping.
 Otherwise, I suggest that you click on the blue categories to the right of each
page to see which articles are available, or go to Articles By Publication Date,
or use the Search function at the top of each page to look for topics.

My Background



I started keeping bees as a hobbyist around 1966, and then went on to get
university degrees in biological sciences, specializing in entomology.  In 1980
I began to build a migratory beekeeping operation in California, and currently
run around 1000-1500 hives with my two sons, from which we make our livings
(update: Eric and Ian are in the process of taking over the operation–allowing
me more time for research).

In 1993, the varroa mite arrived in California, and after it wiped out my
operation for the second time in 1999, I decided to “hit the books” and use my
scientific background to learn to fight back.  I started writing for the
American Bee Journal in 2006, and have submitted articles nearly every month
since then (see “Articles by Publication Date”).

My writing for the Journal brought me requests to speak at beekeeping
conventions, which has also allowed me the chance to visit beekeepers from all
over North America and several other continents.  I read most every scientific
study relating to beekeeping, and regularly correspond with beekeepers and
researchers worldwide.

What I try to do in my articles and blogs is to scour scientific papers for
practical beekeeping applications, and to sort through the advice, opinion, and
conjecture found in the bee magazines and on the Web, taking no positions other
than to provide accurate information to Joe Beekeeper, following the suggestion
in 1922 by New Zealand beekeeping author Isaac Hopkins:

That scientific accuracy, as opposed to rule of thumb, or guess-work methods, is
much needed in commercial production to attain the success we should aim for,
will be acceded by all intelligent beekeepers. There are many, however who do
not realise this, or at all events, do not sufficiently appreciate the principle
in their practice, but are content muddle along in a slipshod fashion to their
great loss.   From THE BEE WORLD February 1922

I regularly update the articles on this site as new information becomes
available, and solicit constructive criticism or comments.  Perhaps the best
venue for such discussion is at the Informed Discussion of Beekeeping Issues and
Bee Biology.  Be sure to subscribe to updates, and I’ll email you monthly when I
add content to the site

Updates (I will not share your personal info or email with anyone, nor clog your
inbox; I update once every few months at best).

EXTENDED-RELEASE OXALIC ACID

I get a lot of questions about my research into extended-release oxalic acid
(“OAE”).  This treatment is not yet approved for use in the U.S., but I suspect
that it will be a game-changer for managing varroa.  Researchers can find
details on how I created the test sponges for my 2020 trials at the end of Mite
Control While Honey is on the Hive: Part 4

For instructions for preparation and use of OAE under permit, see How to Use
OAE.

I’ve created a very useful varroa control model for all to use–check it out
here.  It is designed to run in Excel, and can be used to run simulations for
mite management in your own operation.



Nicole from Heritage Acres interviewed me about the state of bees, breeding for
mite resistance, and extended-release oxalic acid, treatment-free beekeeping,
mite drift, and my recent research.  You can listen to it at this  podcast

My assistant Brooke Molina shot a quick video of me demonstrating how to use my
home-made plastic cups to perform a swirl-type mite wash–showing how it takes
less than 4 minutes per hive.  Randy’s Mite Wash Video

EXTENDED-RELEASE OXALIC ACID

There is a crying need for a safe and effective varroa treatment for use during
hot weather, when there are honey supers on the hive.  I am working with
USDA-ARS to get this application method approved by EPA.  My latest update is
at: Extended-Release Oxalic Acid Progress Report

An objective assessment of the neonics

I was recently asked to write an assessment of the neonics targeted for the
nursery trade group–the University of California Nursery and Floriculture
Alliance.  It’s brief and simple.
You can read it here: link

MY COLONY AGE DISTRIBUTION CHART

I get a lot of requests for the colony age distribution chart that I created
from Lloyd Harris’ data from Manitoba hives.  Thanks to beekeeper Kat Satnik for
pointed out a typo in previous versions.   You can download a copy here.




Mite control updates 25 January 2018

Many of you have noticed the recent discovery that lithium salts may be of use
in varroa control.  I’ve gotten some lithium citrate and will be testing this
season.  It is currently legal to feed colonies  a lithium salt as a nutritional
supplement, but I cannot recommend putting it into your hives prior to further
formal testing.

Re oxalic acid in glycerin (oxalic shop towels), I’ve made big strides in
developing protocols for incubator trials this winter to test various
formulations for best efficacy against the mites, coupled with minimal adverse
effects to the bees.



These cup cages in my home incubator allow me to place precise amounts of
various oxalic acid solutions on a measured square of cellulose fabric (note the
blue piece of towel in the left hand cage) sized to be proportional to the
surface area of the combs in a hive (using a piece of beeswax-coated plastic
foundation as proxy).  The screens at the bottoms of the cups allow me to
measure the percentage of mites killed by the treatment.



I’ve also recently perfected a protocol that allows me to quickly titrate the
amount of oxalic acid that actually gets transferred to the bees’ bodies (note
the pink indicator solution in the cup with bees).  I’ve only run one formal
trial using this method so far, but it shows great promise for me to be able to
quickly screen for the optimal application method for distributing oxalic acid
within the hive.

I thank you all for your donations in support of this research.  I will continue
to publish and post updates.

The 2017 Eclipse

Thanks to Idaho beekeepers Steve Sweet and Kevin Duesman  for inviting Stephanie
and I to join the Treasure Valley Beekeepers Association in camping out and
viewing the eclipse directly under the path of totality!



We also shared the experience with some other bee researchers–Annette Bruun
Jensen (from Denmark), Dennis vanEngelsdorp, and Steve Sheppard.

Update 10 March 2017 to the OA shop towel link below 

There has been huge interest in my article from the Jan ABJ on extended-release
oxalic acid dissolved in glycerin, and applied on shop towels.  Please go to
 this link for
updates: https://scientificbeekeeping.com/oxalic-shop-towel-updates/

Updates: Jan 29, 2016

California almond season is upon us!  We’ve had it easy the past few seasons in
almonds, since the lack of rain during our drought kept the orchards relatively
dry.  Not so this year!  The orchards are a mess, and many are impassable.



My sons Eric and Ian, and I spent the past week welding up our new boom loader
(original design, on the truck to the far right, largely constructed while
working under a tent during the rain).  We got a 3-day break in the rain this
week, and used the window of opportunity to start moving our hives into the most
problematic orchards.  I took the photo of Eric and Ian with our three trucks as
we arrived in the morning for offloading.  It was relatively dry upon arrival,
but it started raining shortly thereafter, and was a sloppy mess by the time we
had finished unloading two hours later (after having to replace one loader
motor, and swap a battery between the trucks–the usual almond problems).

The drought made beekeeping really tough last season, and we had to feed a
record amount of pollen sub and syrup to our colonies in late summer and fall.
 Varroa only added to our problems.  But we poured TLC (and dollars) into our
hives, with the result that our colonies are looking OK for almonds (knock on
wood).

I’ve added several new articles to the website, continuing on Colony Buildup and
Decline, as well as investigating the fermentation of beebread
(see https://scientificbeekeeping.com/articles-by-publication-date/).

I also updated my ppt on oxalic acid.

Beekeeper Jeff Anderson (and coplaintiffs) have recently filed a lawsuit against
EPA to remove the current loophole that allows growers to plant
pesticide-treated seed without the normal restrictions regarding pesticide
application. EPA interpreted existing law as such:
Treated seed (and any resulting dust-off from treated seed) may be exempted from
registration under FIFRA as a treated article and as such its planting is not
considered a “pesticide use.” 
The above loophole has allowed serious problems with planting dust to remain
unresolved.  The lawsuit explains that the current EPA guidance document:
 states there will not be investigation or enforcement against any of their bee
kills or other harm caused by neonicotinoid-coated seeds or resulting
contaminated dust because the kills and other harm incidents are “not considered
a ‘pesticide use.'”

Although I am not of the anti-neonic camp, and feel that seed treatments are
perhaps the best use of neonics, they are indeed potent insecticides, and anyone
(including the guy pulling the seeder) should have training in pesticide
application, and follow restrictions to reduce pesticide drift.  Thus I feel
that beekeepers should support Jeff in this important lawsuit.  Read more at:
(Broken Link!) http://pollinatorstewardship.org/?p=3903

On the subject of pesticides, Dr. May Berenbaum has recently published the most
succinct summary of the history of insecticide use that I’ve had the pleasure to
read.  Read it at: (Broken Link!) Does the Honey Bee “Risk Cup” Runneth Over?

We’re now pushing 30 years with varroa, and from the look of it, in many
operations varroa is winning.  Lately I’ve been giving presentations on “A New
Era in Mite Management,” which I plan to spin into a series of articles.

I’ve also got a backlog of research trials that we’ve done (funded by the donors
to 澳洲幸运5开奖结果历史查询 ScientificBeekeeping), but have not yet had time to publish.
 There just haven’t been enough hours in my days, due to building our operation
and my many speaking engagements.

The good news is that we’ve finally reached the point that my sons are getting
ready to take over the reins of our business (now at around 1200 hives), which I
hope will free up time for me to catch up on the home front and concentrate on
beekeeping research (as well as to improve the website).

Updates: Jan 9, 2016

A recently-filed lawsuit by beekeeper Jeff Anderson deserves our support, in
order to close a huge loophole in pesticide regulation.  Currently, the EPA does
not classify pesticides applied on treated seed as pesticide “applications,” and
are thus exempt from the restrictions and liability due to drift or misuse as
are other pesticide applications.  The registration of seed treatments as
pesticide applications will allow better monitoring of the overall environmental
impact and fate of seed-applied pesticides (not only the neonics).  For more
information, see: (Broken Link!) Pollinator Stewardship News.

Also, see my updates on oxalic acid at Varroa treatments

Updates: Nov 2

There have been a couple of excellent and objective reviews of our state of
knowledge on the effects of neonicotinoids on bees.  Both are open access.  The
lay reader may wish to simply read the summaries in the second link.

A restatement of the natural science evidence base concerning neonicotinoid
insecticides and insect pollinators

A restatement of recent advances in the natural science evidence base concerning
neonicotinoid insecticides and insect pollinators

I’ve updated my analysis of the recent paper Neonicotinoid pesticides severely
affect honey bee queens.

I also suggest the reading of an excellent Master’s Thesis by Julia Goss of the
Swedish University of Agricultural Sciences: Neonicotinoids and Honeybee Health.
 Julia tracked varroa, nosema, and virus levels in 96 colonies, equally divided
between 16 fields of oilseed rape, half seed treated with clothianidin, half as
untreated controls.  She measured parasite levels before (June) and after
flowering of the crop (late July-early August).  Results: despite the confirmed
exposure of the Test colonies to clothianidin at much higher rates than we ever
see in North America, there were no differences in any of the parasite levels
following exposure to the insecticide.

Update: August 23: I was asked to comment on Harvard Medical School’s Dr. Lu’s
recent paper on neonics in Massachusetts.  This may be of interest to those re a
general discussion of the issue of good science vs. poor science.  Read it at A
Review of Dr. Lu’s Latest.

Update June 26: I added a post that I made to Bee-L on monitoring varroa at
Monitoring Varroa.

Update May 9: I’ve updated First Year Beekeeping, an added  Oxalic acid dribble
tips.

April 29: I’ve been derelict in updating the website, and have about 12 articles
to post.  A number of ABJ readers have asked me to post the following graphic
from one of my recent articles.

You can view a full-sized version at Colony Demography.

I occasionally comment on bee issues or the news, or link to interesting blogs
by others on beekeeping, bee biology, or the environment.

The “Flow Hive”

In recent months there has been a great deal of buzz about the “Flow Hive,”
developed by a father/son team of Australian beekeepers.  The device consists of
an arrangement of molded plastic parts that act as foundation upon which the
bees build honey combs, but which can then be shifted by the turn of a handle to
break open the cells of ripe honey and allow it to drain out of the hive through
 tubes.  Although innovative, it is similar to a patent from 1939
(http://www.freepatentsonline.com/2223561.pdf).

The Flow Hive is likely the most well-funded beekeeping device ever brought to
market, due to its inventors incredible media-savvy marketing via crowd sourcing
on the internet.  By means of producing brilliant and compelling fundraising
videos, they have raised enough money to bring their product to market.  Kudos
to them!

I suspect that much of their funding has come from non beekeepers, who have
always been fascinated by the promise of hive from which liquid honey could be
directly taken without the need for actually handling bees.

The question regarding the Flow Hive is whether it will turn out to be
practical, especially with regard to cost and whether it will stand up to
repeated use.  Longtime beekeepers tend to be skeptical, since we’ve seen so
many beekeeping inventions come and go over the years.

But who knows?  I’m as eager as anyone to see whether the Flow Hive proves to be
a revolution in beekeeping.  We’ll see once the completed hives get delivered to
buyers.  I wish the developers the best of luck.  Only time will tell whether
the device actually flies or flops.

Neonics in Ontario

A recent hotbed of anti-neonic activism is Ontario, Canada, in which an unlikely
coalition of a few beekeepers and some media-savvy NGO’s is pushing the
government to ban these insecticides.  Let me state very clearly that I myself
support organic and sustainable farming, use of Integrated Pest Management, and
greatly reduced use of pesticides.  That said, I feel that any pesticide
regulations, and agricultural recommendations, should be based upon sound
science.

An exemplar of this philosophy is Dr. Terry Daynard, formerly a professor and
Assistant Dean of the Ontario Agricultural College, and currently a farmer
himself.  Daynard recently received the “2014 Farm & Food Care Champion” award
from Farm and Food Care.org, with the introduction that “Daynard is a champion
of agriculture in many ways. He is respected as a farmer, scientist, innovator
and agricultural advocate, speaking up and advocating sound science even in the
presence of criticism by those that don’t agree with him.”

Dr. Daynard applies a sound and scientific assessment of how misinformation can
taint well-intentioned environmental regulation in his blog “Critique of “A
Proposal for Enhancing Pollinator Health.””

We all want to minimize agriculture’s negative effects on the environment.  This
includes greatly reducing our reliance upon pesticides.  But such reduction
needs to evolve as we learn (or re learn) alternate and more sustainable
strategies for growing food.  This is best done by rational and sober scientific
assessment of current and alternative practices.  I commend Dr. Daynard pointing
this out.

I’m also  impressed by a recent blog by Dr. David Zaruk, who is a Risk
Governance Analyst at Risk Perception Management and an Assistant Professor
Adjunct in Communications at Vesalius College, VUB, and Facultés universitaires
St-Louis in Brussels.  He blogs under the name of the “Risk Monger.”  He
recently posted about the real-life agricultural and ecological consequences of
the politically- (as opposed to scientifically-) motivated suspension of neonic
seed treatments in the EU.

Dec 2, 2013 If you have interest in the recent petitions to ban the neonics, I
recommend reading a letter to the respected journal Nature by a British bee
researcher, Lynn Dicks, in which she points out the problems with hurried
setting of policy based upon political pressure rather than upon careful
scientific evaluation of the evidence
 http://www.nature.com/news/bees-lies-and-evidence-based-policy-1.12443

Such a careful evaluation of all evidence is what I’m all about, even if that is
unpopular with those who don’t want to be confused by the facts.  I currently
feel that the problem with planting dust from corn seeding has finally reached
the point where the manufacturers either have to take responsibility for
compensating beekeepers who suffer losses due to the application of their
products, or EPA and PMRA need to restrict the use of neonic seed treatments to
only planters that pass dust emission certification.  However, I feel that to
date there is not enough evidence to call for a complete ban on the
neonics–there are simply too many beekeepers successfully keeping healthy hives
in areas of seed-treated crops.  Clearly this is a hot issue, and the neonics,
along with all pesticides need to be closely watched and regulated.  It appears
to me that our regulatory agencies are doing a good job at this, even if
progress seems to be excruciatingly slow.

 

The most recent blog of interest is on the real people involved in biotechnology
(GMO’s).  Steve Savage writes:

“As with any new technology, the development and commercialization of biotech
crops is a story about people.  Its a story about people with ideas and vision;
people who did hard and creative work; people who took career or business risks,
and people who integrated this new technology into the complex business of
farming…  Their story is important, but it tends to get lost in much of the
conversation about biotech crops.

Many narratives about “GMOs” leave out the people side, presenting it instead as
some faceless, monolithic phenomenon devoid of human inspiration, intention and
influence. Thats not how it happened.  Other narratives about “GMOs” demonize
those who made biotech crops a reality. Such portrayals are neither fair or
accurate.  The real stories of these people matter, because trust in a
technology is greatly influenced by what people believe about those behind it.”
