Although I would like to save the bees, this is a bit beyond my skills as a beekeeper. I've read and know the procedures, but I'm not up to the task (Yes, I'm chicken!). Anyway, the tree is located within five miles of the Saugerties exit on the N.Y. Thruway (Exit 23 I believe) and the bees are there for the taking if anyone is interested. Time is critical here as the bees are causing a bit of a problem with the land owners animals (horses, dog, and son). The limb fell about four hours ago (About noon on 6/18). If there are any takers or free advise, E-Mail ASAP! ========================================================================= Date: Thu, 21 Jun 90 20:59:00 EDT Reply-To: Discussion of Bee Biology Sender: Discussion of Bee Biology From: General Delivery Subject: JUNE ISSUE OF APIS--PLEASE ACKNOWLEDGE RECEIPT TO MTS@IFASGNV FILENAME: JUNAPIS.90 Apis--Apicultural Information and Issues Florida Extension Beekeeping Newsletter Volume 8, Number 6, June 1990 STOCK INTRODUCTION IN FLORIDA Mr. Laurence Cutts, Florida Chief Apiarist, recently sent a memo out to interested persons concerning events in Florida. Of special interest are two importations of honey bees. Dr. Roger Morse of Cornell University was able to bring 26 British queens into the U.S. to investigate resistance to tracheal mite. Daughters were reared and allowed into Florida for testing. Florida cooperators in this project, according to Mr. Cutts, are David Miksa and Mel Greenleaf. A progress report on this research was printed in the June issue of "American Bee Journal." It was written by Dr. Norman Gary, University of California, Davis, who, along with Dr. Robert Page of the same institution, developed an experimental technique to look at resistance. Although full details are not yet available, Dr. Gary believes there was no difference in mite resistance when British and American stocks were compared. However, hybrids did show a "statistically significant degree of resistance," indicating that "hybrid vigor" may be an important element to look at in the future. Dr. Gary promises a full report of this work will be published soon. The potential importation of Carniolan (Apis mellifera carnica) bees into Florida to look at Varroa resistance is also mentioned by Mr. Cutts. At the present time, Dr. Tom Rinderer, USDA-ARS Baton Rouge Bee Lab, has applied for a permit to bring in progeny of bees that have shown resistance in Yugoslavia. The parental stock was brought to a Louisiana barrier island and kept in isolation for eight months. Once daughters are reared and introduced, the original parental stock will be destroyed, providing at least one generation of bees as a safety buffer in case pests or diseases might be present. The Florida Arthropod and Arthropod Pathogen Introduction Committee of the Florida Division of Plant Industry has granted permission to introduce the offspring which will be tested in cooperation with Horace Bell Honey Co. in Deland, Florida. However, USDA-APHIS must first act to allow the bees entry from the barrier island to the U.S. mainland. The hue and cry for importing everything from African bees to the Asian honey bee (Apis cerana) can be heard everywhere. The latter insect has a number of fans. It appears to be a good pollinator; is resistant to Varroa; and will not cross with the African honey bee. Beekeepers use it in many countries in Asia with success. Dr. Siriwat Wongsiri, University of Bangkok, Thailand, however, has recently published an article concerning problems with "Apis Cerana" in the developing countries of Southeast Asia (Honey Bee Science, Vol. 10:4 pp. 160-164. According to an English summary (the original text is in Japanese), use of Apis mellifera is on the rise and there are half as many colonies of cerana as mellifera now being used. Beekeeping with cerana is less because of the inability to control swarming and absconding resulting in lower honey yields. Significant problems using cerana also continue to be European foulbrood susceptibility and lack of basic knowledge about keeping the bee. Perhaps the best of all worlds would be a mellifera-cerana mix of bees. This controversial possibility was reported by Dr. Eric Mussen in his latest "From the UC Apiaries." The same Dr. Wongsiri mentioned above has apparently reported that mellifera colonies will accept frames of emerging cerana brood. The cerana bees then groom their mellifera sisters in the colony, removing and biting the Varroa mites. What the beekeeper winds up with is a sub-population of honey producing mellifera cared for by a sub-population of cerana! Many also favor bringing in African bees from Brazil or Africa. One reason is that both Brazil and Africa report fewer disease problems; however, as the article on the numbers game in this newsletter reports, there are disease problems in Brazil. Nevertheless, those promoting importation use the rationale that because the U.S. now has Varroa, and tracheal mites, nothing new could possibly hurt the U.S. beekeeping industry. This concept is debatable. An interesting situation has arisen in Argentina, presumably due to importation of a large quantity of queens from the U.S. American foulbrood, previously unknown in that country, is now epidemic. In addition, for some reason it doesn't appear to respond to treatment from Terramycin (R) at the same dosages used in this country. Levels of up to 1200 mg active material must be used as opposed to the 200 mg recommended in the U.S. This has proven disastrous for beekeeping in certain regions of the country. The reason the queens were brought to Argentina was simple economics--they cost less to import because the value of the U.S. dollar was low. Although regulations exist in the country to prevent introduction, this shipment was somehow cleared through customs. This Argentinian case and others (many previously believed that introduction of tracheal mites into the U.S. was not a serious threat to bee colonies) reveal why there has and will continue to be controversy over importation. Although most persons agree that stock introduction is needed in some cases, there is a great deal of concern about the methods involved. Unfortunately, no guidelines exist. Offspring of the British bees were allowed into Florida because they originated on U.S. soil and so were treated just like any others. In the case of the Yugoslavian bees, a state committee approved the permit, but there continues to be no standard importation criteria that can be followed for subsequent introductions. FLORIDA LEGISLATION The conclusion of the Florida legislative session will mean more regulations involving beekeepers and honey marketers. Fines for misuse of pesticides have been increased from $1,000 to $10,000 for each violation. In addition, in the near future it appears that the Florida Department of Agriculture will develop standards and inspection procedures for food labelled as organic. It also seems that the African bee awareness plan published in the January issue of this newsletter was not funded. This is not surprising considering the bee has yet to cross the Texas border. But, like good sports teams, the players will live on to propose this valuable program again next year. THE NUMBERS GAME On several occasions, I have discussed "the numbers game." This is an overriding concern for a large number of colonies a beekeeper manages. The results of this can be twofold: trying to manage more colonies than time permits or an area can support and/or spending valuable time coaxing along weak colonies at the expense of more pressing demands of the operation. Hints that reliance on the numbers game is not profitable are seen in the June issue of "American Bee Journal." Mr. Frank Steinoble, a successful beekeeper in South Africa, has made as much as $425,000 per year on bee pollination and honey production according to Ms. Sandra Crow. Proper management and close supervision are key factors in Mr. Steinoble's success. As Ms. Crow says, "He warns there are various ceilings to one's business; that there is a point when one has reached the ultimate profit for a stated number of hives." Mr. Hubertus Von Posern of Austria, writing in the same journal part two of a series on the Brazilian Apimondia Congress, also alludes to the numbers game. Brazilian beekeepers claim to have few disease problems with their bees. But Mr. Von Posern doubts high disease resistance in the African bee. Rather, he witnessed beekeepers killing off weak colonies with few qualms. These losses are easily replaced by swarms. As he concludes: "Imagine if we could afford this beekeeper's practice of destroying anything weak! How much healthier our apiaries would be! We learned at the Convention that bee diseases do exist in Brazil after all." News from Bill Clarke, retired apiculturist from Penn State University who visited Egypt as part of the "Farmer-to-Farmer" development project, is revealing: "It is true that Varroa is creating difficulties for the Egyptian beekeeper but we feel that the major problem continues to be the decrease per colony in honey production that has occurred over the last twenty years. We feel that a major contributor is the huge increase in the number of colonies. There is a limit to the amount of nectar that any given area can produce." An example given by Mr. Clarke: In 1979 - 200 colonies produced 20 kilograms each totalling 4000 kgs. In 1989 - 1000 colonies producted 4 kilograms each totalling 4000 kgs. NOTE THAT THE SAME AMOUNT OF HONEY WAS HARVESTED IN BOTH YEARS! As Mr. Clarke concludes, "Time and equipment are being wasted in building large numbers of colonies. One strong colony can outproduce four or five weak ones." SPONSORS FOR EGYPTIAN BEEKEEPERS NEEDED The Farmer-to-Farmer program will enter a new three-year phase this year. It will include a two-way exchange allowing 180 Egyptian farmers and extension agents to receive 30 days on-farm training in the U.S. Mr. Clarke says some five beekeepers will be coming in September and he is looking to find a place for three of them. Some will speak English and all will be enthusiastic, intelligent and cooperative workers. A $20.00 per day stipend for bed and board will be available. Any farm family wishing to host an Egyptian should contact Umesh Mally, Director of Global Programs, Agricultural Cooperative Development International, 50 F St., N.W., Suite 900, Washington, DC 20001, ph 202/638-4661 or FAX 202-626-8726. BEEKEEPERS INSTITUTE Planning is well underway for Florida's annual Beekeepers Institute to be held August 24, 25 and 26 at 4-H Camp Ocala. This year's program features discussions on effects of mites in Florida and the coming of the African honey bee. Dr. Jim Tew will be a featured speaker. Dr. Tew is National Program Leader for Apiculture for the Cooperative Extension Service, United States Department of Agriculture (USDA). He writes "Apicultural Awareness," a newsletter on events surrounding activities of USDA's Interagency Technical Working Group on the Africanized Honey Bee. In addition to learning how to detect both tracheal and Varroa mites, research on mites will be discussed by representatives of the University of Florida and Florida's Division of Plant Industry. Dr. Glenn Hall, Honey Bee Geneticist at the University of Florida, will also provide some information on beekeeping with African bees in South Africa. He and Dr. Orley Taylor spent several weeks in that country looking at beekeeping practices. As is customary, a flyer detailing the registration procedure will be mailed to the APIS mailing list soon. This year's fee is $65.00 for lodging and six meals. After August 6, a late fee of $20.00 will be charged, so get your registration in early. You should receive the flyer by the middle of July. If it hasn't arrived by then, contact your local Cooperative Extension Service office or me. Each Extension Office will be able to access the registration form through the IFAS Computer Network. THE OTHER HALF OF BEEKEEPING Dr. Roger Hoopingarner, in his newsletter "B-Plus," from Michigan State University, is concerned about the other half of beekeeping. This refers to the need to be more aware of nectar resources and the changes that are affecting them. Dr. Hoopingarner says that much of this is not within the beekeeper's influence. However, the situation can be helped by encouraging plantings along roadsides or seeding small patches of high yielding nectar plants. Graham Kleinschmidt of Queensland Agricultural College in Australia also counsels more active management of plant resources. These include attempting to gain access to governmental areas not currently available to apiarists and encouraging flora on public lands. These plants could be selected for characteristics that will not interfere with activities, but will provide ease of maintenance and be sources of nectar and pollen. As Mr. Kleinschmidt concluded in remarks made to the Second Australian and International Bee Congress, "A viable beekeeping industry requires land management that promotes polleniferous flora. If the present decline in available pollen resources continues, the effects of poor protein nutrition will make honey production uneconomic. If this eventuates the major national cost will be to agricultural production which will be adversely affected by the inability of the beekeeping industry to service entomophilus crops." Reports show that many of the powers that control public lands in Florida have not received the above message. Thus, a great deal of public land is not available to beekeepers, and in some areas, like state preserves, honey bees are seen as introduced species, precipitating movement to remove colonies already present. The argument that bees are foreign to the natural environment does not hold much water. Many plants in preserves are introduced as well. Keeping managed colonies out of public lands is not expected to appreciably decrease the bee population. Indeed, when African bees arrive, the lack of managed colonies on public lands may well be perceived as a health hazard. The more defensive insect will have less competition and, as in tropical Latin America, will immediately fill up the empty ecological niche left by those attempting to preserve a "natural" state of affairs. Like so many things in Florida, paying attention to the other half of beekeeping means only one thing. A concerted lobbying effort by beekeeping associations on local and state authorities to open up and keep available public lands for beekeeping. Only one major nectar source, citrus, is cultivated in Florida. The rest are wild plants. They require cultivation by the whole state. In return, those agriculturalists requiring pollination will continue to get bees at a reasonable rate. In the end, the citizens of Florida will be able to continue to have access to wild land and lower cost food in the bargain. Sincerely, Malcolm T.

Volumes are small, but I have access to high performance liquid chromatography (HPLC) equipment. My initial forays into the literature on Apis honey analysis have not led to work using HPLC that I might follow as a guide. Can anyone on Bee-L direct me to useful literature or, better, to an active researcher. Or, if you are experienced in HPLC, can you offer guidance on such arcana as dilution, derivitization, etc. At the same time, do you have access to wasp honeys - of any taxon of social Vespidae - that you could send to me for inclusion in the survey? I would be most appreciative and would gladly acknowledge the contribution. I can be reached directly at C4926@UMSLVMA, by FAX at 314-553-6233, or by snail mail at Department of Biology, University of Missouri - St. Louis, St. Louis, MO 63121. Many, many thanks.
