        HEATHER POMEROY SELECTED AS THE NEW 1993 AMERICAN HONEY PRINCESS
             Iowa's 1992 State Honey Queen, Heather Pomeroy, was selected
        as  the 1993 American Honey Princess by the  American  Beekeeping
        Federation  at their annual convention in Kansas  City,  Missouri
        January 23rd.  As a result, Heather will travel all over the U.S.
        this  year assisting the American Honey Queen in promoting  honey
        and beekeeping.  The title of 1993 American Honey Queen was given
        to Tennesee's state honey queen, Gena West.
 
        PRESIDENTS MESSAGE
             Fellow beekeepers, its already February and another year has
        come  and  gone.   Its time to file taxes  again;  figuring  your
        profit, loss and deductions this time of year is not fun.
             Last  year the ASCS's five-year state average was 83  pounds
        per colony.  If your bees produced less than this in 1992 you may
        be  eligible  to receive disaster relief  payments.   The  filing
        deadline is February 13,  1993.   We hope for a better honey crop
        in 1993.
             February is also a good time to start preparing for  spring.
        Take count of what you will need for equipment and bees.   Repair
        and paint your old boxes.   Be sure to put new foundation in your
        frames so that they'll be ready when its time to go through  your
        colonies and make splits in April and May.
             I've  talked  to several beekeepers who have found  some  of
        their colonies dead.  This was due to the lack of feed going into
        winter.   So  it would be wise to check your  bees'  food  supply
        whenever  we  get some warm days in the next  several  weeks.   I
        really think we will have to feed as soon as we can this spring.
             Our next IHPA board meeting will be March 6th.   If you have
        any questions or want any topic brought up,  please contact  your
        district director or one of the officers to get it on the meeting
        agenda.
                                         - Leroy Kellogg, IHPA president
        IHPA BOARD MEETING HIGHLIGHTS
             The first meeting of the 1993 board was held December 5th in
        Huxley at 1:00 p.m.  Eight members were in attendance.
             New treasurer,  Bob Shepherd reported a total of $3269.33 in
        revenue  was received at the annual meeting but all expenses  had
        not yet been paid.  Some of the IHPA funds will be transferred to
        a money market account in order to get a higher interest rate.
               Questions  to be answered before the association  makes  a
        cash  grant to another organization and instructions  are  listed
        below:
        1.   Do they need it? Did they send a written request?
        2.   What will it be used for?  Who will spend it?
        3.   What  will it accomplish?   Are there long term benefits  to
        the beekeeping industry or bee research,  particularly as related
        to IHPA interests?
        4.   When  a  grant of money is sent to another  organization,  a
        request  for  a copy of research results and a  financial  report
        will be made in a cover letter to be sent with the check for  the
        money.
             A  request was made by the Honey Queen committee to pay  the
        expenses for sending Heather Pomeroy to the American Honey  Queen
        contest in Kansas City, January 19-23,  1993.   Approval was made
        to  spend  up  to  $500 for  the  hotel,  meals,  transportation,
        registration fees,  and miscellaneous expenses.  Paul Goossen was
        appointed  as  chairman of the queen committee  this  year,  with
        Hildegard Goossen, Bev Powell, Elaine Johnson and Bob Cox also on
        the committee.
             A  discussion on the summer field day led to the  suggestion
        that  several field days be held in different areas of the  state
        in June, July or August.  Dates and places will be established at
        the March 6th board meeting.
             A motion was made by John Johnson and passed to send $100 to
        the Iowa Agriculture Youth Institute.   Several other promotional
        items were referred to the promotions committee for action.   Ann
        Garber  was appointed to chair the committee again this year,  if
        she is willing.
             John  Johnson  was  appointed chairman  of  the  state  fair
        salesbooth committee again this year, with Arvin Foell and Walter
        Clark  also on the committee.   A suggestion was made  to  change
        some  of  the awards in the Cooking with Honey  Division  because
        they have been the same for a few years.   A motion was passed to
        add  a  new beeswax art class in place of the frame of  cut  comb
        honey  (Class  12).   We will now have four beeswax  classes:   3
        pound bulk,  candles (molded or dipped tapers),  poured mold art,
        and handcrafted art (not from a poured mold).
             A motion passed to pay mileage to and from the fair for  the
        chairman  of  the state fair committee at the rate of  $0.10  per
        mile.   Discussion was held on the association selling  honey  at
        the  All-Iowa Store at the State Fair.   John Johnson is  working
        with  the Iowa Horticultural Society to get bids for honey to  be
        sold at the All-Iowa store.
             Bob Cox led a discussion of the proposed bee law and  apiary
        rule  changes.   A  motion passed by a unanimous  hand  count  to
        recommend that bee law and apiary rule changes be pursued in 1993
        (as outlined in the handouts).  Marvin Trojahn agreed to  contact
        Senator Vande Hoef of Harris, Iowa to sponsor a bill with the bee
        law changes.   Bob Cox will file for the apiary rules changes  on
        behalf of the Department of Agriculture.  These changes allow for
        more  flexibility because of increased mite levels and  available
        effective treatment options.
 
        STATE APIARIST REPORT
             Its  surprising  how much harsh weather  we're  having  this
        winter  in  Iowa.    Hopefully,  the  snow  will  serve  as  good
        insulation and a windbreak for the bees.  However, the bees could
        use a warmer day for a cleansing flight.   The tracheal mite  may
        cause extra beekill this winter because of the higher  percentage
        of  positive  samples  collected last summer and  the  poor  late
        season honey flow.  See the article on page 7 for more details on
        tracheal mite samples collected last year.
             Plan  on attending one of the beekeeping workshops  in  your
        area  this spring.   An interesting program is planned and its  a
        good opportunity to meet other beekeepers in a smaller group than
        at the annual meeting.  If you are a seasoned beekeeper, come and
        bring a less experienced friend along for an informative evening.
        See the article on pages 5 & 6 for the complete schedule.
             We  are  planning on another Honey promotion  with  the  Des
        Moines  Botanical Center again this year in March and April.   If
        you  would be willing to help man the booth under the dome for  a
        few  hours,  contact Ann Garber,  promotions committee chair,  at
        (515)  872-2119 or give me a call at (515) 281-5736.   IHPA  will
        provide  honey candy to give away and will bring in the  National
        Honey Board's mascot, Buzzy Bear, for a visit on Easter day.
 
        IN THE BEEYARD
             Spacing  frames in the beehive is a topic that  varies  with
        each beekeeper's viewpoint.  In nature, we find combs spaced from
        1 3/8,  1 1/2, 1 5/8 inches and sometimes up to two inches apart,
        from center to center.
             The 10-frame Dadant hive is built to accommodate ten  frames
        with the 1 3/8 inch spacing.  Some beekeepers use fewer frames in
        this size of equipment.   You,  as a beekeeper,  should adopt the
        spacing which will give you the best results:  the most brood and
        honey.
             Wherever wider spacing is used,  there is likely to be  more
        honey  stored  in  the combs in the  honey  supers.   When  wider
        spacing is used in the brood nest,  there tends to be more  honey
        stored, more drone brood and less worker brood in the comb.
             Some researchers say that close spacing (1 3/8 inches) tends
        to encourage the rearing of more worker brood,  less drone  brood
        and the storage of less honey.  If this is so, this is the way we
        would like to have it in the brood chamber.
             Finally,  spacing still remains a management  decision  only
        you, as the beekeeper, can determine.
                                  - Robert L. Wells, Asst. State Apiarist
 
        VARROA GETTING NASTY IN CALIFORNIA AND NEW YORK
             Dr.  Eric Mussen reports that many California beekeepers got
        a  surprise when their colonies collapsed last  fall,  apparently
        from  damage caused by the Varroa mite.   Finding a mite  or  two
        doesn't  mean the colony is in immediate jeopardy,  but  it  will
        require treatment sooner or later according to Mussen.
             Although  it has been reported that colonies sometimes  take
        several years to die after being infested with Varroa,  there are
        exceptions.   Dr.  Roger Morse of Cornell University speaks of  a
        New York beekeeper whose hives produced over 100 pounds of  honey
        in July and August, yet were dead by late fall.
             Dr. Mussen describes a California beekeeper's situation, who
        after a good producing season,  saw 75% of his colonies  severely
        damaged  or dead by Christmas.   That beekeeper is no  longer  in
        business and had to sell out at submarket prices.   These  severe
        cases  may  be  caused  by drift of  bees  from  nearby,  heavily
        infested  apiaries that were not treated.   Also,  the fact  that
        mites  are  hidden and protected in capped brood cells  may  mean
        there was a serious undercount of those mites found on adults.
             The  technology  to  determine when  a   Varroa  infestation
        reaches  a treatable level by any detection method  currently  in
        use  is not well developed.   Detection results may vary and  are
        dependent on bee/mite population dynamics.   For example,  in the
        fall,  Dr.  Morse says,  with little or no brood,  you  are  more
        likely to find mites on adults,  whereas in the spring it will be
        easier  to  find mites in brood.   Practical  experience  by  the
        Florida  Division of Plant Industry indicates that when 20  mites
        in  a  ether roll of approximately 300 bees are found,  a  colony
        should  be  treated  with Apistan strips.   However,  Dr.  Harvey
        Cromroy  of the Entomology-Nematology Department,  University  of
        Florida, believes more than five mites is a treatable level.  Dr.
        Morse  concludes finding 30 or 40 per hundred bees (by the  ether
        roll method) is serious and the colony may be beyond saving.  The
        ability to correlate ether roll data with other detection methods
        is not presently available.  (Information taken from the  Florida
        apiculture newsletter,  "APIS", edited by Tom Sanford,  Extension
        Apiculturist, University of Florida)
 
        BEEKEEPING COURSES IN RAPID CITY
             Beekeeping  courses for beekeepers in the central U.S.  will
        be  taught  at Western Dakota Vocational-Technical  Institute  in
        Rapid  City,  South Dakota this winter and spring.   The  courses
        will be taught by Dr. Charles P. Milne, Jr.   Dr.  Milne has over
        20  years  of beekeeping experience,  has  taught  beekeeping  at
        Washington State University,  and is now a commercial  beekeeper.
             Three  different weekend short courses will be  offered  for
        beekeepers  in the central states area.   The dates are  February
        20-21,  March 6-7,  and March 20-21.  The weekend schedule allows
        for  travel to Rapid City on Friday,  and a mixer is planned  for
        those arriving early.   The instruction will take place  Saturday
        8-12 noon,  1-4, 7-9; free time Sunday morning;  and last session
        1-4  p.m.  on Sunday.   Attending all short courses will  provide
        beekeepers with a broad knowledge base on beekeeping.   The first
        short course provides essential information on the honey bee  and
        the colony,  and some beekeeping basics.  The second short course
        emphasizes colony management.   The third short course  discusses
        hive products, queen rearing, diseases, and the Africanized honey
        bee.  Any single short course can be taken independently.
             For further information on the courses, contact Dr. Milne at
        (605)  393-0049  or  Kelley Osborn or Jerry  Johnsen  at  Western
        Dakota Vo-Tech at (605) 394-4034.

        IOWA HONEY QUEEN PROGRAM
             Wanted  -  Beekeepers  who are willing to work  and  have  a
        vision  of future possibilities.   You must be willing to  invest
        time,  effort and a personal interest in another  person  without
        expecting to see a dollar in return (at least, in the short run).
        But  you will be investing in the lives of young people  and  the
        future of the honey industry.   Do not expect to receive a "thank
        you"  for your efforts,  but you will receive a sense  of  having
        served for the good of others.
             The  assignment is to encourage,  sponsor and educate  young
        ladies to be honey queens to represent the honey industry in your
        community, in Iowa and even, in the United States, if you do your
        job  well.   If  you decide to accept  the  assignment,  you  can
        identify  an interested young lady, age 10-16 years old,  sponsor
        her and we, as the honey queen committee, will give you some help
        and guidance.
             Hopefully,  we  could  have  a number  of  local  queens  as
        candidates  for  the state title and hold a special  honey  queen
        seminar for them,  covering:   1.) basic beekeeping,  2.) uses of
        honey,  and 3.) public speaking.   What a wonderful way to help a
        young  person develop invaluable leadership and public  relations
        skills!  What a wonderful way to bait a hive and catch a swarm of
        honey sales in the future!
              To do this,  we will need to be willing to look beyond  our
        immediate,  individual  interests to tomorrow and  other  people.
        Thus  the saying,  "One sows and another reaps"  is true.   After
        all,  it is also true that we have benefited from others also ("I
        sent you to reap that for which you have not worked.   Other have
        done  the  hard work and you have reaped the  benefits  of  their
        labor".   If anyone understands this principle,  it should be the
        beekeeper,  as he gathers the bees'  honey and comtemplates  this
        principle in other areas of life.

        TRACHEAL MITE INFESTATION IN IOWA
             The laboratory test results for tracheal mites is listed  in
        the table below: 1.) the number of samples tested, 2.) the number
        of  infested  apiaries  and 3.) the  number  of  beekeepers  with
        infested apiaries for 1989-1992 in Iowa.
 
 
 
 
 
 
 
 
 
 
             The percentage of apiaries and beekeepers with infested bees
        is shown in the next table.   The level remained fairly  constant
        around  30%  for  the first three years.   However,  in  1992  it
        increased,  with  75%  of the samples infested  and  81%  of  the
        beekeepers having at least one infested apiary.   This may not be
        a fair sampling because of the small sample size, therefore, this
        may not be an actual increase.
 
 
 
 
 
 
 
 
 
 
 
             Also  listed  in  the  second table  is  the  percentage  of
        infested   apiaries   that  exceeded  the  15%   allowable   mite
        infestation  level.   This percentage seems to  have  been  lower
        during 1990 and 1991, but up again in 1992.   These 30 beekeepers
        with  infested colonies were required to treat for  the  tracheal
        mite  because  their  apiary(s) posed  a  threat  to  neighboring
        apiaries.
              If  this apparent increase in tracheal mite infestation  is
        real,  we  may see a larger than normal winterkill  this  spring.
        However,  if  the infested apiaries were treated in  a  way  that
        resulted in lower mites levels before winter,  then the mite  may
        have little effect on wintering loss this year.
             In  order to better evaluate the health of Iowa's honey  bee
        population,  a  larger  number of random bee  samples  should  be
        collected and examined in 1993.  If you would help,  we could get
        samples from most of Iowa's 99 counties and from a larger  number
        of beekeepers,  perhaps 250-300 samples total.  Contact the state
        apiarist's  office  to  get instructions on how  to  collect  the
        samples.   We need random samples, rather than only samples  from
        weak colonies likely to be infested with the mites.
 
        NEW LABELING LAWS FOR HONEY
             Although  honey may have the image of being  an  unprocessed
        natural  product,  it too will be required to  provide  nutrition
        information  on  its'  label in  accordance  with  the  Nutrition
        Labeling  and  Education  Act of 1990.   Honey  is  traditionally
        processed  to  145  F for 30 minutes to kill yeasts  and  prevent
        fermentation.   This heating process is included in the Food  and
        Drug  Administration  (FDA) definition of a  processed  food  and
        requires adherence to the new labelling regulations.
             According to the proposed regulations,  the serving size for
        honey  is one tablespoon,  which will serve as the basis for  the
        nutrition  information on the label.   The  proposed  regulations
        also stipulate that the honey industry use a simplified nutrition
        label which lists just calories,  total fat,  total carbohydrates
        (sugar), protein and sodium.
             This  nutrition information can be provided in column or  in
        paragraph form.
 
 
 
 
 
 
 
 
 
 
 
 
 
             Please  note that 60 calories is listed as  the  appropriate
        value for honey using USDA calculation of 3.68 calories per  gram
        of honey.    Honey contains 17.3 grams of carbohydrate  resulting
        in 53.66 calories per serving size.  This number is rounded to 50
        calories,   the   nearest  10  calorie   increment.    Grams   of
        carbohydrate  are  expressed  to the  nearest  gram,  making  the
        carbohydrate declaration 17 grams.
             Exemptions  to  this proposed labeling law include  a  small
        business exemption; bulk foods shipped for processing,  repacking
        or labelling;  foods in packages with less than 12 square  inches
        of label space,  provided that nutrition information is  supplied
        at  point of sale*;  and food for institutional use if  nutrition
        information is provided directly to these institutions.
        *(If   this  exemption  is  used,  a  company  cannot  make   any
        nutritional claim on its'  label.  Additionally,  FDA knows of no
        reason  why  firms  could not provide  nutrition  information  on
        placards in a clear and conspicuous way at the point of sale.)
             This  information  was provided by Richard Sullivan  of  the
        National  Honey  Packers  and  Dealers  Assn.    from  Focus   on
        Value-added  Agricultural  Products,   Vol  1  #11  Kansas  State
        University Cooperative Extension Service Sept/Oct 1992.
 
 
 
        For example, in column  form,  the       In paragraph form,   the
        label would
        label would appear as shown:             appear as follows:
