Small hive beetle is now a serious pervasive pest of beekeeping in Australia in areas with mild winters and humid wet summers. Although a number of internal trapping systems are available, it is desirable to intercept small hive beetles before they enter a hive. This research will benefit the Australian honey bee industry by providing a trapping system for small hive beetle including a simple trap and knowledge of when best to deploy traps and where best to locate the trap in respect of hives. The key findings are that natural fermentation attractants while useful are subject to variation; thus development of a synthetic lure blended from the key attractant components in fermentation volatiles should be the ultimate goal. Results from investigations into the placement of traps and movement of small hive beetles throughout the year in Australia have provided invaluable ecological data to inform external trapping and monitoring strategies. This study emphasises the importance of beekeepers managing the increase in numbers of small hive beetles potentially entering their hives during spring and after wet periods during late summer and early autumn. This report is an addition to AgriFutures Australia’s diverse range of over 2000 research publications and it forms part of our Honey Bee and Pollination Program. The R&D program aims to support research, development and extension that will secure a productive, sustainable and more profitable Australian beekeeping industry and secure the pollination of Australia’s horticultural and agricultural crops into the future on a sustainable and profitable basis.

    NSW APIARISTS’ ASSOCIATION INC. Bees and beekeepers are essential for Australia Submission to the Australian Senate Inquiry into: The future of the beekeeping and pollination service industries in Australia To the Senate Standing Committee Please find here the submission from the New South Wales Apiarists’ Association (NSWAA) to the Senate Inquiry: Future of the beekeeping and pollination service industries in Australia. NSWAA is the state peak body for commercial beekeepers, and the Association represents its members to all levels of government. There are currently around 3,000 registered beekeepers in NSW, which represents about 45 per cent of Australia’s beekeeping industry. NSW commercial beekeepers manage over 140,000 hives, but these numbers are declining at an alarming rate – 30% since 2006 – and this is reflected nationally. While the beekeeping industry is a relatively small one, it plays a highly significant role within the agricultural sector of NSW, and more broadly across Australia. Beekeeping is essential not just for honey and other hive products, but also for pollination of the food crops that feed us and our livestock. Most importantly, our industry stands between Australia and a looming food security crisis. However, Australian commercial beekeepers can’t stave off this crisis without assistance. There are three significant threats to our industry, which endanger the vital pollination services provided by beekeepers. These are access to floral resources, pests and diseases, and increasing pressures on the industry’s economic viability. We address these issues in detail below. We would like to thank the Senate Standing Committees on Rural and Regional Affairs and Transport for making available this opportunity to provide you with this submission on the importance of beekeeping and pollination services in Australia.

  • Future of Beekeeping and Pollination Services in Australia
    SUBMISSION TO SENATE ENQUIRY BURNETT BEEKEEPING SUPPLIES FUTURE OF BEEKEEPING AND POLLINATION SERVICES IN AUSTRALIA Burnett Beekeeping Supplies are a regionally based manufacturer of quality Australian hoop pine hives, beekeeping foundation and supplies. We are based in Kingaroy in Queensland and are committed to quality products for Australian apiarists. We are passionate about the future of the beekeeping industry and have invested in a wax processing plant in addition to our wood manufacturing plant. Burnett Beekeeping Supplies are making this submission to the Senate Inquiry, as we are concerned about the biosecurity arrangements of imported beekeeping equipment. We would like to make the following recommendations – 1. Greater restrictions to be put on the import of wooden hive products from overseas for biosecurity reasons. The continuation of imported wood products increases the risk of disease coming into Australia via these wood products. 2. Subsidise businesses that manufacture Australian made beekeeping products as a risk management strategy. Australian manufacturers struggle to compete with overseas imports due to Australia not having the same labour costs and taxes as our competitors overseas. What if in the future suppliers from overseas are unable to supply, due to natural disasters, war or for biosecurity reasons? In the meantime Australian suppliers and manufacturers of beekeeping supplies have closed down due to not being able to compete. The loss of Australian manufacturers could lead to short supply of beekeeping products, which could result in the loss of our bees and no pollination of food. 3. Greater restrictions to be put on the import of wooden hive products from overseas due to the additional threat to Australia’s wood manufacturing and forest industry.

On average, 100–120 beehives were 700 hives. Average annual yield for a skilled operator is 100– periodically placed on each occupation permit site, the number 120 kg per hive. To achieve this, beehives are transported from and location being determined by the flowering of species which one location to the next. Most beekeepers operate within 200 km beekeepers regarded as reliable producers of nectar and pollen. of their home base for most of the year, with occasional trips Commercial apiaries were also periodically placed adjacent to outside of this range to particularly good and reliable nectar flows, State forests, allowing the bees to fly to the floral resources of for over-wintering or to escape drought closer to home.

  • Journeyman Level Master Beekeepinjg Course
    JOURNEYMAN LEVEL MASTER BEEKEEPINJG COURSE April 7, 2014 Class No. Four HONEY BEE PESTS AND DISEASE TRACHEAL MITE (Acarapis Woodi) Mites that infest the tracheae (breathing tubes) of honey bees were found in the U.S. for the first time in July, 1984 on the U.S. – Mexican border. It is microscopic in size. Female tracheal mite is looking for a newly emerged bee about 3 days old or less, whose exoskeleton’s odor is different from an older bees. She will transfer to the host and go into the first thoracic trachea. If she cannot find a host, she will crawl off and die. Grease patties causes all the bees to smell or have the odor like that of an older bee, which the tracheal mite does not like. Chemical control of the tracheal mite is done with Mitathol which has menthol in it. If the temp is too great, it will run the bees out of the hive. The Mitathol needs to be put on the bottom, if the temp is too high, greater than 85 degrees. The adults pierce the trachea and suck blood (hemolymph) from the bee. They live 30 or 40 days. Hive Treatment--Apply grease patties, one in the fall of the year (early Oct) and one in the spring (early march). Two parts sugar; one part Crisco. Tracheal Mites Tracheal mites are microscope mites which reproduce in the trachea (airways) of the bee. A visual aid that would suspect tracheal mites would be a large number of bees walking about the outside of the hive.

Using a social-ecological system approach to enhance understanding of structural interconnectivities within the beekeeping industry for sustainable decision making. Ecology and Society 25(2):24. https://doi. org/10.5751/ES-11639-250224 Research Using a social-ecological system approach to enhance understanding of structural interconnectivities within the beekeeping industry for sustainable decision making Vidushi Patel 1,2, Eloise M. Biggs 3, Natasha Pauli 1,3 and Bryan Boruff 1,2,3 ABSTRACT. The social-ecological system framework (SESF) is a comprehensive, multitiered conceptual framework often used to understand human-environment interactions and outcomes. This research employs the SESF to understand key interactions within the bee-human system (beekeeping) through an applied case study of migratory beekeeping in Western Australia (WA). Apiarists in WA migrate their hives pursuing concurrent flowering events across the state. These intrastate migratory operations are governed by biophysical factors, e.g., health and diversity of forage species, as well as legislated and negotiated access to forage resource locations. Strict biosecurity regulations, natural and controlled burning events, and changes in land use planning affect natural resource-dependent livelihoods by influencing flowering patterns and access to valuable resources. Through the lens of Ostrom’s SESF, we (i) identify the social and ecological components of the WA beekeeping industry; (ii) establish how these components interact to form a system; and (iii) determine the pressures affecting this bee-human system. We combine a review of scholarly and grey literature with information from key industry stakeholders collected through participant observation, individual semistructured interviews, and group dialog to determine and verify first-, second-, and third-tier variables as SESF components.
