Some beekeepers question the need for funding bee research. Because
they don't see any obvious benefits, they feel research is not
that important. Any type of research is fraught with frustration
- for every fruitful product of research there are at least 10
projects that end with no discernible benefit. As one sage (Marston
Bates) put it "Research is the process of going up alleys
to see if they are blind." Too many beekeepers focus on
the blind alleys and not on the sporadic successes and feel they're
not getting the bang for their bucks. Researchers, feeling the
pressure to produce results, tend toward safe projects rather
than take a flyer on a project that shows no immediate promise
of results but, if pursued in depth, could provide spectacular
benefits.
In recent years, the almond industry has funded more bee research
than the bee industry (a fact that should embarrass beekeepers).
If, as a few beekeepers think, beekeeper funding of research
is a poor investment, then almond growers must be assessed as
not being very smart. Such an assessmeht flies in the face of
my observations as all the almond growers I've encountered appear
to be just as smart (and just as independent) as beekeepers.
Bee research has greatly benefited California beekeepers over
the years, although in ways that are not readily apparent. Allow
me to point out some of these benefits.
I got started in the honey bee pollination business in 1959,
working for a commercial pollination company managed by Charles
Reed and based in the San Joaquin Valley. In 1960, a large melon
grower in Western Fresno county had heard that bees might be
beneficial to melons but needed more proof before he spent big
bucks on bee rental. Reed had close ties with Frank Todd and
Sam McGregor of the USDA Bee Lab in Tucson and they provided
the necessary proof (based on their research): that the size
of a melon is dependent on the number of seeds it contains and
the number of seeds is based on the number of pollen grains transferred
(a prime cantaloupe requires the transfer of about 400 pollen
grains which in turn requires about 10 bee visits per flower).
This research data convinced the grower and he rented 3,000 bee
colonies for his 3,000 acres of melons at alfalfa seed pollination
prices ($6.00/colony at that time) and he came up with the best
yields he ever had. The idea of renting bees for melons is now
an accepted practice in California and in the years since 1960,
melon pollination fees have put millions of dollars in beekeeper
pockets.
Like Jim Robertson (August issue) I also encounter considerable
price cutting on melon pollination. A few years back I told our
largest melon account that part of the reason for our high prices
was that the stronger hives we supplied lost weight (consumed
honey) during melon bloom; you're trying to get the crown set
on melons and there are simply not enough flowers to support
the bees. This potential honey loss provides an impetus for beekeepers
to select colonies with the lowest populations (often divides)
for melon pollination and to put their better colonies on honey
locations.
To prove my point with the melon account mentioned above, I rigged
up two scale hives and had the grower record the weights daily.
As with most melon bees, the hives came out of the oranges quite
heavy and at the end of the melon pollination period (before
there were copious melon flowers) the scale colonies had lost
roughly 20 lbs. or $10 worth of honey each. The following year
(at the suggestion of a beekeeper who is a bit smarter than I
am) we weighed two bee trucks (120 colonies per truck) as they
went into the melon fields and again as they came out. One truck
lost 20 lbs. per colony and the other 30 lbs. (per colony) and
the grower was satisfied our prices were justified. Funding a
similar study by a respected institution (beekeeper data lack
credibility) could help beekeepers maintain higher melon pollination
fees (for growers with on-ranch scales I can see a fee based
on weight-in and weight out). Such a study, if funded, should
be done well before cotton bloom and the melon field(s) should
be isolated from any significant nectar sources (a normal state
of affairs for most melon pollination). To make it more interesting,
the weight change of a load of eight-frame strength bees (or
divides) could be compared to a load of 16-frame strength bees.
There is much less research data on the benefits of strong colonies
for melons than there is for almond and alfalfa seed. Perhaps
a study could be initiated to show that melon growers could get
by with less colonies per acre (and lower per-acre pollination
costs) if strong colonies were used.
More recent melon research by Frank Eischen, et al has shown
that bee deliveries to melons can be delayed long enough for
growers to get one or more pre-bee sprays (if needed) with no
loss in melon production.
Alfalfa Seed
The history of alfalfa
seed pollination in California is also research based. Alfalfa
seed production in California started in the late 1940s, at which
time there were many questions as to whether honey bees could
do the necessary tripping of alfalfa flowers to effect pollination.
Honey bees were ineffective pollinators of alfalfa in the main
seed producing areas at the time (the Midwest and Pacific Northwest)
because they just didn't or wouldn't trip the flowers. Todd and
McGregor showed that in the drier climates of the desert areas
of the southern San Joaquin and Imperial Valleys, honey bees
were effective pollinators of alfalfa (due in large part to accidental
tripping by nectar collecting bees because flowers tripped more
easily at lower relative humidity). As the humidity has risen
in the San Joaquin Valley (due to widespread irrigation that
has changed what was once a desert into an agricultural oasis)
alfalfa flowers don't trip as easily as they did 50 years ago,
but honey bees still do the bulk of alfalfa pollination in California
and probably always will.
Pollination fees for alfalfa seed have put millions of dollars
in the pockets of California beekeepers over the years and it
is research that laid the foundation for this bounty. One of
McGregor's students, Mike Rosso, now operates an alfalfa seed
pollination service and commands a premium price for the beekeepers
that work through him. Growers are willing to pay this premium
price because Rosso has shown them the research data that justify
it. Similarly, many beekeepers are able to command a premium
pollination price for almonds (and for other crops) because of
research that has shown that higher priced hives are usually
worth the extra money.
Cotton
Although bees have
not been proven to be essential for cotton in California, the
scattered research reports that have shown benefits from bees
(you don't get any more bolls, but more seeds per boll, thus
bigger bolls) have helped me to get cotton locations for beekeepers
(and have made at least a few cotton growers more careful about
their pesticide programs). A past study in California failed
to prove the benefit of bees to cotton because it was impossible
to get a check (no-bee) field but it is felt that cotton fields
in alfalfa seed areas get better yields because of their proximity
to large populations of honey bees.
Pesticides
Research on the toxicity of pesticides to honey bees is another
area that has helped all California beekeepers. Bee-pesticide
research, particularly that by Larry Atkins, has led to judicious
use of certain pesticides around bees and has saved billions
of honey bees over the years, particularly in the San Joaquin
Valley. When a beekeeper says he's getting "clobbered"
by a certain pesticide, his words don't carry a lot of weight,
but if research data can be shown that a particular pesticide
is indeed a serious hazard to bees, people take notice and restrictions
are put in place. It's a "show me the data" world and
Atkins and others provided the necessary data, in good part through
the use of dead-bee traps placed in hive entrances.
An interesting pesticide problem around 15 years ago was also
solved by research: beekeepers claimed they were getting clobbered
by the pesticide Monitor, yet Atkins' dead-bee traps indicated
that Monitor was a relatively safe material to use around bees.
The losses claimed by beekeepers were due to queen and brood
loss and didn't show up until well after the Monitor was applied
- Monitor was a stealth killer that had slipped in under the
radar. Beekeeper claims were ignored until Eric Mussen, in a
neatly designed experiment, provided the necessary data to show
that Monitor did indeed cause severe bee losses. The use of Monitor
around bees is now greatly restricted and such restrictions,
based on research data, have saved millions of bees.
Pesticides and oranges
Bee-pesticide research
has also helped California beekeepers make more orange honey.
As a former San Joaquin Valley beekeeper, I made virtually all
my honey during the two to three week period of orange bloom.
One of the reasons I got out of the bee business is that just
as my hives were going gang busters on orange bloom, the grower
would "have to" spray with a highly toxic material.
The year after I sold my hives a spray moratorium was put in
place in the citrus areas of the San Joaquin Valley - growers
can't spray with highly toxic materials from 10% bloom till petal
fall. If a grower does have a pest problem, he is allowed to
use certain materials (e.g., lannate) that have been shown, by
research, to be relatively safe to use around bees if applied
before 7:00 a.m. or after 7:00 p.m. The result of this research-based
moratorium has put millions of dollars in beekeeper pockets through
increased orange honey production and reduced pesticide losses.
Summing up
The vast majority of
beekeepers support funding of research (although they may disagree
on the method of funding) just as the recent referendum showed
that the vast majority of beekeepers support the Honey Board
(in spite of the somewhat paranoiac implication by a few beekeepers
that this vote was in some way not representative). The vocal
few who rail against spending money on research make a noise
far out of proportion to their numbers. The enthusiasm with which
these few present their case has a certain appeal but when their
case is examined closely, little of substance can be found.
In recent years, California farmers, beleaguered by their small
representation in state and federal legislatures, have erected
billboards stating "When you complain about agriculture,
don't talk with your mouth full." A similar phrasing could
apply to beekeepers, especially California beekeepers, that complain
about funding research.
