Demand from the cosmetics industry remains healthy, but the use of beeswax in candles, which was very strong a few years ago, has dropped considerably as consumer interest has shall we say, flickered. Or burned out.
Produced naturally by some ants as a defense against predators, formic acid can be dangerous in large quantities if handled improperly. And it must be reapplied frequently to be effective against bee mites, according to the article's lead author, Jan Kochansky, Ph.D., of the USDA's Bee Research Laboratory in Beltsville.
Two compounds are widely used in the United States to control bee mites: the pesticide fluvalinate used for varroa mites and menthol used for tracheal mites. While menthol remains effective against tracheal mites, varroa mites in some regions of the United States have developed resistance to fluvalinate, as has already occurred in parts of Europe. "The migratory nature of commercial beekeeping means that this resistance will spread rapidly to most areas of the country," claims Kochansky. Another compound, coumaphos, is used in some states to help control fluvalinate-resistant varroa mites, he notes.
A patent for the formic acid gel is pending; a manufacturing license has been issued to BetterBee, Inc. of Greenwich, N.Y. EPA registered the gel in August.
The article by Joe Humphreys further states, " Attacking the bee's immune system, varroa leaves it crippled and susceptible to viruses. If a colony becomes infected it will collapse, sending the survivors out in search of another hive, thus spreading the parasite further." For many years, Ireland was the only country in Europe free from the mite having introduced a ban on bee importations in 1980. "Our big fear was that a swarm would come across on the ferry in the back of a truck," said Mr. Don Feeley, a senior inspector with the Department. "Unfortunately, what happened was someone deliberately brought in bees from England, ignoring the ban." He said the Department had identified three different individuals responsible for breaches of the law, one of whom distributed infected bees throughout County Sligo, leaving a trail behind him. The Department had considered taking legal action but "it's impossible to prove anything".
"We anesthetize the bees with carbon dioxide and then glue tags onto their backs," explains Ronald Gilbert, who is testing the technology at the Pacific Northwest Nation-al Laboratory, in Richland, Washington. The tags contain radio-frequency-emitting chips, much like the ones stores put on clothes to thwart shoplifters. The laboratory's workers shrank the tags to half the size of a grain of rice. Antennas at the entrance to the hive pick up radio frequency signals from the tag. A computer analyzes the data to tell whether bees are coming or going. Upon returning to the hive, each bee is identified by its tag and greeted with a puff of air. The air sweeps molecules into a mass spectrometer, which measures their atomic weights and compares the results with those for TNT. If the explosive is identified, the computer system updates its map of known minefields. Police then post warning signs for as long as it takes sappers to remove the mines.
Tom Theobald, president of the Boulder County Beekeepers Association and owner of the Niwot Honey Farm, said that based on a 1996 survey of beekeepers, half the losses beekeepers report are directly attributable to pesticides. The number of colonies in Colorado until 1996 was 45,000, and now it is between 22,000 and 32,000, he said.
"Toxic Pollen From Widely Planted, Genetically Modified Corn Can Kill Monarch Butterflies, Cornell Study Shows" An increasingly popular commercial corn, genetically engineered to produce a bacterial toxin to protect against corn pests, has an unwanted side effect: Its pollen kills monarch butterfly larvae in laboratory tests, according to a report by Cornell University researchers.
Writing in the latest issue (May 20) of the journal "Nature", the Cornell researchers note that this hybrid crop, known as" Bt"-corn, has genes from the bacterium" Bacillus thuringiensis" ("Bt") spliced into the plant genes. These hybrids are very effective against the ravenous European corn borer, a major corn pest that is destroyed by the plant's toxic tissue. The engineered corn is safe for human consumption.
Unlike many pesticides, the "Bt"-corn has been shown to have no effect on many "nontarget" organisms -- pollinators such as honeybees or beneficial predators of pests like ladybugs. But the "Bt-"modified corn produces pollen containing crystalline endotoxin from the bacterium genes. When this corn pollen is dispersed by the wind, it lands on other plants, including milkweed, the exclusive food of monarch caterpillars and commonly found around cornfields.
Says John E. Losey, Cornell assistant professor of entomology and the primary investigator on the study: "We need to look at the big picture here. Pollen from "Bt"-corn could represent a serious risk to populations of monarchs and other butterflies, but we can't predict how serious the risk is until we have a lot more data. And we can't forget that Bt-corn and other transgenic crops have a huge potential for reducing pesticide use and increasing yields. This study is just the first step, we need to do more research and then objectively weigh the risks versus the benefits of this new technology."

NEW YORK -- Bees are thriving in seven high-rise hives.
Bears are nonexistent. Skunks are rare. Rats, pigeons and humans,
though plentiful, are reluctant to approach.
New York City, it turns out, is a great place to be a bee.
"They do really well here," said David Graves, who has hundreds of
thousands of honeybees in seven hives in Brooklyn, the Bronx and
Manhattan. "There are so many parks, and gardens, and rooftop flowerpots.
Even if it's dry, they can get the water they need from the East River."
They mind their own beeswax, too, and don't go around stinging sidewalk-
bound New Yorkers, Graves insisted. The hives are on rooftops -- as high
as 12 stories -- to keep them undisturbed. Each of Graves' hives can produce
50 pounds of honey a year, which he sells for $5 per half-pound at the
city's greenmarkets. His ordinary New England honey is $3.
Graves, 48, has been raising bees for 15 years. He got the up-on-the-roof
idea one spring after black bears raided hives near his Becket, Mass., home.
Dear colleagues: I am beginning a study on the parasitic fly genus
Melaloncha that attacks stingless bees in the New World tropics. I am
looking for collaborators in the Neotropical Region who would be willing to
help me. I need people who can direct me to nests of as many stingless bee
species as possible. Once I know where the nests are located, I can search
for the parasitic flies, which often are found around the nest entrance. By
the way, the flies also attack honey bees and can be a major source of
mortality for these insects.
If anyone has an interest in this project, please contact Brian Brown - bbrown@nhm.org.
-Brian says thanks.
Researchers, led by Dr. Tom Rinderer, had expected mite populations to increase by a factor of about 12 during the test period, but on the Russian stock, populations only grew about 3 times from the original mite counts. Although other factors may be involved, the results - that a genetic resistance to varroa mites may be discovered - are very encouraging! The complete Science News article is on the web.
Garth Cambray of Camdini Apiaries, South Africa, says that they will not infect a hive unless something is already badly wrong with it. If the hive is killed by pesticides, or has it's population dramatically reduced so it cannot defend itself against beetles, the beetles will hammer the hive.
More on the life cycle, longevity, and control of the hive beetle is located here.
The introduction states in part: "This report updates information on honey production, pollination and the relationship of the U.S. beekeeping industry to agriculture and the environment. The study was mandated in the Committee report that accompanied the Agriculture, Rural Development, and Related Agencies Appropriation Act of 1987. The mandate resulted from concern by beekeepers and members of Congress about problems, issues, and challenges that emerged during the 1980's with the potential to significantly alter the beekeeping industry. These concerns included northward migration of the Africanized honeybee, infestations of colonies by tracheal and Varroa mites, the widespread use of highly toxic pesticides, increasing honey imports, and efforts to discontinue the honey price support program."
This report is an extremely valuable lobbying document. The authors should be congratulated for providing the industry with these facts and figures. The beekeeping community now has plenty of ammunition to back up its arguments for public support in many arenas. However, the time and expense to produce this document will go for naught, if those in the beekeeping industry do not actively use the information to its fullest potential. To obtain a copy call toll free 800/999-6779 in U.S. and Canada (other areas 703/834-0125) and ask for AER-680. The cost is $12.00 payable by Visa or MasterCard.

United Press International, also in April, 1998, carried a similar story, citing the "killing (of) millions of honeybees in western France." The syndrome was termed 'mad bee' because the honeybees, apparently poisoned by an insecticide designed to injure an insect's neurological system, causes bees to loose their cognitive abilities, resulting in (among other things) bees which can not find their way home. Beekeepers claim the problem is the insecticied Gaucho, produced by German agrichemical giant Bayer. It was designed to protect sunflowers from parasites. French Ministry spokesman Andre Lesireux described his department's research: "The research will tell us why the bees turn crazy and die."
Texas Department of Agriculture Dismisses Free Speech Case Against Beekeeper
After a two and a half year legal battle, the Texas Department of Agriculture has dropped charges that beekeeper John Caldeira broke the law simply by talking about pesticides on the Internet.
In 1995, the Texas Department of Agriculture (TDA) sent beekeeper John Caldeira a letter in the mail claiming that he broke the law when he discussed the merits of Mavrik, a pesticide, in controlling varroa mites in beehives on Prodigy's bee hobbyist bulletin board. Under Texas law, a pesticide distributor can lose his license for "recommending" a pesticide inconsistent with its labeling or approved EPA use. But Caldeira wasn't a distributor of pesticides or even a commercial beekeeper. He was just a hobbyist repeating what he'd learned from USDA researchers at beekeeping conventions.
The TDA went after him anyway, claiming that his Prodigy posts "gave the impression" that he was a knowledgeable commercial beekeeper whose "advice and suggestions would have a significant impact in encouraging illegal use of Mavrik." They inspected Caldeira's hives and found no violations of the law. Still, they pursued Caldeira, seeking to fine him $600. Caldeira countered that his comments were factually accurate, harmed no one and were protected by the First Amendment.
After bringing his case to the readers of Fight-Censorship, an electronic mailing list, attorney Jennifer Granick put Caldeira in contact with Texas attorney McGready Richeson. Richeson, representing Caldeira pro bono, moved to challenge the TDA's actions on First Amendment grounds, filed for a stay of the proceedings and prepared to file a declaratory action to determine the constitutionality of the statute.
In response, TDA drafted a statement for Caldeira to post "one time per month for three months" to Prodigy, parroting the TDA's position on pesticide use, in exchange for dropping the fine. Richeson rejected the offer, stating that no offer which forced Caldeira either to remain silent or to speak would be acceptable.
Meanwhile, the TDA's case was in trouble. On January 12, 1998, Administrative Law Judge Barbara C. Marquardt granted Richeson's Motion to Continue, stating that "the nature of this action is problematic. While it is filed against a Texas resident, it concerns information he placed on the Internet, and no harm was done to Texas residents... Thus, the ALJ would prefer that a district court address the constitutional issues." That same day, the TDA dropped their case against Caldeira.
The largest honey marketing co-operative in the USA estimate honey sales are up about 10 per cent over last year (mostly in increased sales of lower value industural bulk honey). Members delivered about 36,400,000 pounds of honey from their 1997 crop, nearly twenty per cent of the total US production.

There is a little more mite news floating around the country. Apparently, an efficacy experiment in a southern US state involving ten-year old Apistan strips (sold in 1989) demonstrated that the old strips were much better at killing varroa than strips produced today. The apparent recent loss in Apistan strip effectiveness is believed to be due to formulation changes in the host material (the plastic that holds the miticide in the strip), which no longer releases the chemical correctly. There had been speculation that some strains of mites were developing resistance to the Fluvalinate, but it now appears (according to our sources in the south) that the strips just aren't working as they once did. In tests conducted by the producers of Apistan, it has been indicated that the product continues to be at least 95% effective in killing mites - if used correctly. Unfortunately, a correct application would require about five times the number of individual strips per hive than what beekeepers typically use. The resulting cost could finacially destroy some beekeepers (then who would buy the strips?)... It is important for producers of any commodity to keep prices at a level that customers will not go broke making purchases, or, worse turn into mavericks!
