my Oxalic acid grain alcohol mixture seems to have eaten the pump parts on my fogger. Now where did I put my vaporizer. I still have it, somewhere.

Parasite Pressures on Feral Honey Bees (Apis mellifera sp.) Feral honey bee populations have been reported to be in decline due to the spread of Varroa destructor, an ectoparasitic mite that when left uncontrolled leads to virus build-up and colony death. While pests and diseases are known...

Quantitative Virus Dynamics in Honeybee (Apis mellifera L.) Colonies along a New Expansion Front of the Parasite Varroa destructor Over the past fifty years, annual honeybee (Apis mellifera) colony losses have been steadily increasing worldwide. These losses have occurred in parallel with the...

A Virulent Strain of Deformed Wing Virus (DWV) of Honeybees (Apis mellifera) Prevails after Varroa destructor-Mediated, or In Vitro, Transmission The globally distributed ectoparasite Varroa destructor is a vector for viral pathogens of the Western honeybee (Apis mellifera), in particular the...

Honey Bee Apis mellifera Parasites in the Absence of Nosema ceranae Fungi and Varroa destructor Mites Few areas of the world have western honey bee (Apis mellifera) colonies that are free of invasive parasites Nosema ceranae (fungi) and Varroa destructor (mites). Particularly detrimental is V...

Increased Tolerance and Resistance to Virus Infections: A Possible Factor in the Survival of Varroa destructor-Resistant Honey Bees (Apis mellifera) The honey bee ectoparasitic mite, Varroa destructor, has a world-wide distribution and inflicts more damage than all other known apicultural...

An Amino Acid Substitution (L925V) Associated with Resistance to Pyrethroids in Varroa destructor The Varroa mite, Varroa destructor, is an important pest of honeybees and has played a prominent role in the decline in bee colony numbers over recent years. Although pyrethroids such as...

Hello Everyone, I'm new to this forum, I am a first year beekeeper in Nova Scotia Canada. I recently encountered a problem when I checked my hives yesterday (October 3rd). Winter is coming up around where I live and I recently ran into a problem. I have two hives, one I treated for varroa...

Sequence Recombination and Conservation of Varroa destructor Virus-1 and Deformed Wing Virus in Field Collected Honey Bees (Apis mellifera) In areas where V. destructor is established, virus recombination occurs and chimeric viruses between DWV and the Varroa destructor virus-1 (VDV1) [8-10]...

Effect of Flumethrin on Survival and Olfactory Learning in Honeybees Flumethrin has been widely used as an acaricide for the control of Varroa mites in commercial honeybee keeping throughout the world for many years. Here we test the mortality of the Asian honeybee Apis cerana cerana after...

Last year Clover queen bee initiated a thread "Apiguard and other thymol varroicides.." After a slow start the thread picked up but basically no one gave advice based on real experience on how to use thymol and how effective it was for controlling varroa. I'd like to make an attempt at gleaning...

Varroa-Virus Interaction in Collapsing Honey Bee Colonies In colonies where varroa treatment reduced the mite load, colonies overwintered successfully, allowing the mites and viruses to be carried over with the bees into the next season. In general, AKI and DWV titres did not show any notable...

Chemical analysis shows that honey bees (Apis mellifera) and hive products contain many pesticides derived from various sources. The most abundant pesticides are acaricides applied by beekeepers to control Varroa destructor. Beekeepers also apply antimicrobial drugs to control bacterial and...

Bidirectional Transfer of RNAi between Honey Bee and Varroa destructor: Varroa Gene Silencing Reduces Varroa Population We previously reported that honey bees fed on double-stranded RNA (dsRNA) with a sequence homologous to that of the Israeli acute paralysis virus are protected from the viral...

Fine-Scale Linkage Mapping Reveals a Small Set of Candidate Genes Influencing Honey Bee Grooming Behavior in Response to Varroa Mites To search for genes influencing this trait, we used an Illumina Bead Station genotyping array to determine the genotypes of several hundred worker bees at over a...

High-Resolution Linkage Analyses to Identify Genes That Influence Varroa Sensitive Hygiene Behavior in Honey Bees Varroa sensitive hygiene behavior is one of two behaviors identified that are most important for controlling the growth of Varroa populations in bee hives. To identify genes...

The Bite of the Honeybee: 2-Heptanone Secreted from Honeybee Mandibles during a Bite Acts as a Local Anesthetic in Insects and Mammals Honeybees secrete 2-heptanone (2-H) from their mandibular glands when they bite. 2-H is a local anesthetic effective against wax moth larva (WML) and Varroa...

If scientists in several colleges and universities, and several states, and several countries are saying small cell is worthless, and they isolate variables, why believe someone that only lost 30 percent of their colonies last year? Or think logically, when the bees "regress" to small cell what...
