Mite Management in Top Bar Hives

Mite management of top bar hives The varroa mite does not care that you’re keeping your bees in a top bar hive–colonies in top bar hives are just as susceptible to the mite.  Unless you are running a truly mite-proof bee stock, you can expect the same sort of buildup of mite populations as in […]

DWV sampling instructions

Dear U.S. beekeeper, Recent studies by Dr. Stephen Martin and associates have found that there is apparently a benign form of DWV that can out compete the virulent form, thus allowing colonies to survive despite varroa infestation. If this is true, it raises the possibility that we may be able to minimize the effect of […]

Williams, et al (2015)  Neonicotinoid pesticides severely affect honey bee queens.

Updated Nov 2:  The science of the effects of neonics upon pollinators is so contentious, that I am often asked to comment on new published studies.  This study, which claimed an effect of neonics on queen mating, immediately garnered such requests.  Unfortunately, the lead author was at conference at the time, and was unable to […]

A Review of Dr. Lu’s paper on neonics in Massachusetts

A Review of Dr. Lu’s paper on neonics in Massachusetts By Randy Oliver ScientificBeekeeping.com August 18, 2015   I was recently asked by a couple of extension horticulturalists to comment on Dr. Alex Lu’s most recent publication on the neonicotinoid insecticides.  I hesitated to do so, since Dr. Lu feels that I’ve picked on him.  […]

Building a Better Mite Washer

Building a Better Mite Washer – Larry Clamp Notes from Randy: Tinkerer Larry Clamp put together a very nice set up illustrated instructions for building mite washer cups, and is generously sharing them.  Thanks, Larry! The thin black screen from package bee cages (or some older veils) is easier to work with than hardware cloth, and […]

Oxalic Acid Dribble and Sublimation Updates

Update 18 March 2017 When OA dribbling package bees (or perhaps any bees), I’ve received a report from a good source that the bees tolerate the dribble better if they are full of nectar or sugar syrup–presumably because they are then less prone to imbibe the OA syrup. Update 24 Jan 2017 There has been lots […]

Colony Demography

Seasonal demographics of a colony headed by a vigorous young queen, shed wintered in Manitoba.  Each band of color represents the proportion of bees in each 12-day age class at any time point.  Red (0-12 days of age) through green (61-72 days) age cohorts represent short-lived “summer bees,” which rarely live longer than two months.  […]

Tips for Citizen Scientists

Tips for Designing Bee Research Projects Randy Oliver ScientificBeekeeping.com Revised 26 Feb 2017 Beekeepers are known for being of curious and experimental minds. Since factors affecting beekeeping are continually changing, new unanswered questions are bound to arise; the beekeeper “citizen scientist” can often answer them himself by performing a well-designed experiment, and then share those results […]

Pesticide exposure pathways

Sorry for the low resolution of this snip of this Powerpoint slide that I created for a presentation.  I’ve color coded the ellipses and arrows.  Red is the pesticide active ingredient.  Blue is the initial mode of exposure.  Orange are the ages/temporal tasks of the bees involved.  Green are the contaminated foods or combs. Note […]
