Carl Linnaeus
• Carl Linnaeus (1707-1778)
• “The Father of Taxonomy”
• Linnaeus desired to name all insects
• Trained as MD; a Swedish botanist, physician, and zoologist.
• Developed the early stages of ranking and classifying organisms as used today

Linnaeus’s Scientific Thought
• Developed the “binomial nomenclature”
• Binomial = two names (Apis mellifera)
• Nomen (name) clature (what is its name)
![Page 5: Nomenclature - SC State Beekeepers Association...Apr 23, 2016 · •Developed the “binomial nomenclature” •Binomial = two names (Apis mellifera) •Nomen (name) clature (what](https://reader033.vdocument.in/reader033/viewer/2022050400/5f7de68fec881b64331afe60/html5/thumbnails/5.jpg)
Classification
• This is how Linnaeus’ method has evolved. • Kingdom = Animalia (animals) • Phylum = Arthropoda (Arthropods) (jointed foot) • Class = Insecta (insects) • Order = Hymenoptera (membranous wing) • Family = Apidae (long-tongued bees) • Genus = Apis • Species: mellifera (honey-bearing) Source: “Wepidia”

century • Smaller in size, lots of hair • Overwinters with smaller numbers • Uses less store • Builds up rapidly in spring, very gentle • Quick to swarm (because of quick build up) • Swarming makes them more difficult to manage.

Apis mellifera caucasian
• Originates in the Caucasus region; the mountain range diving south eastern Europe from Asia. Imported during the last part of the 19th century.
• Very gentle, grey in color because of the copious hair
• Good producer
• BUT slow to build up in the spring and do not fair well in cool damp climates.

Minnesota Hygienic
• Reduced – Clinical symptoms of American foulbrood or chalkbrood – have significantly fewer Varroa mites compared to
unselected colonies
• good honey producer, and is gentle and easy to manage.
• certify a trait, hygienic behavior. Not concerned with the type or pedigree of bees selected for hygienic behavior; they can be Italian, Russian, Carniolan or mutts! Interested in selecting diverse stocks of bees for hygienic behavior first, and in time, other traits that will help the bees resist diseases and mites

VSH / SMR
• This hybrid has the ability to reduce the number
of viable Varroa Mites in the hive. • There is no bee that is 100% immune to the
Varroa Mite. • Suppressed Mite Reproduction (SMR) is a trait of
honey bees that provides resistance to Varroa destructor. The mechanism of resistance in SMR bees is the removal of infested pupae from capped brood, so a better name is VSH bees (acronym for Varroa Sensitive Hygiene)

Russian Bees
• originate in the Primorsky Krai region of Russia – imported into the United States in 1997
• Varroa mite came to the United States in 1987.
• Russian Carniolan strain improves the survival from Varroa.
• When in the presence of other strains this trait diminishes.

A comparison of various colony characteristics of Italian and Russian honey bees
• Characteristic Italians Russians • Varroa mites More susceptible More resistant • Tracheal mites More susceptible Highly resistant • Brood rearing: Continuous throughout the summer Usually only during times of pollen availability • Robbing High Low • Queen cells: Only during swarming or queen replacement Present most of the time • Pollination skills Small difference from Russian bees Small difference from
Italian bees • Temperament Gentle, less defensive; not likely to sting Gentle, less
defensive; not likely to sting • Color Light Dark

Requeening Italian colonies with Russian queens
• The requeening procedure has frustrated many beekeepers because standard introduction techniques often are not successful when requeening Italian colonies with Russian queens, as the colonies may reject the new queens.
• Italian bee colonies need more time and separation to become acclimated to Russian queens.
• Step 1: Split the colony in half, with the two halves separated by a double screen.
• Step 2: Place the old queen in the bottom half and a caged Russian queen in the upper half.
• Step 3: Release the Russian queen from her cage after 7 to 10 days. • Step 4: Once the Russian queen has been accepted and has laid
eggs for one month, kill the old queen, and reunite the two halves (remove the screens)
