Stress also activating neuropeptide, a neuropeptide known to be present at reduced the amount of octopamine in the brain of pollen foragers (a higher levels in nectar foragers than in pollen foragers (Brockmann biogenic amine involved in the regulation of foraging and flight et al., 2009), is over-expressed in parasitized bees (McDonnell et al., behaviour in insects). According to the literature, flight metabolic rate 2013) provides some indirect support for this hypothesis. Stress can is higher during pollen foraging than during nectar foraging, and decrease sucrose responsiveness (Pankiw and Page, 2003), which is nectar gives a higher energetic return relative to the foraging effort lower in nectar foragers than in pollen foragers (Pankiw and Page, when compared with pollen. -
Swarming (Bulletin #404) (PDF)
Swarming Apiculture Bulletin #404 Updated: 10/15 Swarming is a natural method of honeybee colonies to reproduce, resulting in the creation of a new honeybee colony in addition to the established colony. Contributing factors to swarming • Crowding - too many bees, food stores and no cell space for the queen to lay eggs in. • Poor air circulation • April-May is swarming season and healthy colonies develop strong swarm impulse. • Inclement weather - crowded bees confined by cold, wet weather will build queen cells and swarm out on the first sunny, warm day. All colonies in similar condition will swarm as soon as weather becomes favorable. • Large amount of drone brood in early spring is a precursor to strong swarm impulse. Catching the swarm A swarm generally emerges from the hive between 11:00AM and 1:00PM and settles close to the apiary for several hours. Allow the swarm to cluster for at least 30 minutes before placing the swarm in a single super with frames, bottom board and hive cover. Leave the hive for the remainder of the day to allow all the bees to enter, before moving to a permanent location. Examine the new colony after a week and then every two weeks from mid May to late June. Look for disease, brood abundance, brood pattern and overall condition of the colony. Add room where necessary, cut queen cells, or divide, to prevent other swarms to develop. Hived swarms have no stored food reserves and may go hungry when there is little forage. When feeding sugar syrup, add antibiotics as a precautionary measure. -

Colony Growth and Seasonal Management of Honey Bees
Colony Growth and Seasonal Management of Honey Bees Management of honey bees varies based on whether Although honey is essential food for bees, colonies pollination or honey production is the primary objective. cannot grow without sufficient amounts of incoming A simple scheme for those interested in maximizing honey pollen. Pollen contains the essential amino acids, sterols, production can be a template for any beginning beekeeper. minerals, and vitamins that bee larvae need to grow into Managing honey bees involves seasonal manipulations adult honey bees. Bee colonies cannot grow without brood of hive space to provide room when necessary for the production, and brood production hinges on good-quality expanding brood-rearing area and for storage of surplus nutrition that comes from pollen. Hence, bee colonies grow honey. Good management includes reducing colony space largest during or just after periods of maximum numbers during periods of dearth of incoming food, preventing of blooming plants in the spring and autumn (Figure 1). swarming of bees, feeding food supplements to offset any These periods are called honey flows. shortcomings in winter stores or to help stimulate brood Blooming of food plants can be predicted by a crude production during critical periods of colony development, geographic rule of adding a 1-week delay in bloom for keeping young and good-quality queens in colonies, and every 200 miles or so northward in latitude.

Establishing a Honey Bee Colony
ESTABLISHING A HONEY BEE COLONY SUCCESS IN THE FIRST YEAR Meghan Milbrath, April 2016 Honey bees colonies should live from year to year in most climates where they are kept. Just like other perennials, new honey bee colonies require different care when they are started and their management changes as they become older and more established. In beekeeping, an established colony is one that has survived a winter with a queen and cluster of bees, will generally reproduce (swarm) in spring, have sufficient comb built, and has enough bees to ensure survival (if it is kept free from environmental threats and disease). A new colony is started by one of four ways 1) purchased packages, 2) purchased nucs, 3) caught swarms, and 4) splits. In all of these cases, the population will be much smaller, will not have the same ratio of all ages of bees, and will not function like a fully operating colony. A new honey bee colony has one goal - grow large enough to have enough food to survive its first winter. In Northern climates, where the season is shorter, new colonies often cannot become fully established by the time winter sets in without extra help from the beekeeper. Picture a new colony like a baby animal, or a new fruit tree. While an older animal may be able to fend for itself, a young one cannot. And while an older fruit tree will bear fruit, a young seedling will put its energy into root production and growth. Likewise, a new honey bee colony will need more support while it is small, and it will likely not provide a crop during its first year. -

Bee Health: the Role of Pesticides
Bee Health: The Role of Pesticides Renée Johnson Specialist in Agricultural Policy M. Lynne Corn Specialist in Natural Resources Policy February 17, 2015 Congressional Research Service 7-5700 www.crs.gov R43900 Bee Health: The Role of Pesticides Summary Over the past few decades there has been heightened concern about the plight of honey bees as well as other bee species. Given the importance of honey bees and other bee species to food production, many have expressed concern about whether a “pollinator crisis” has been occurring in recent decades. Although honey bee colony losses due to bee pests, parasites, pathogens, and disease are not uncommon, there is the perception that bee health has been declining more rapidly than in prior years, both in the United States and globally. This situation gained increased attention in 2006 as some commercial beekeepers began reporting sharp declines in their honey bee colonies. Because of the severity and unusual circumstances of these colony declines, scientists named this phenomenon colony collapse disorder (CCD). Since then, honey bee colonies have continued to dwindle each year, for reasons not solely attributable to CCD. The U.S. Department of Agriculture (USDA) reports that CCD may not be the only or even the major cause of bee colony losses in recent years. In the United States, USDA estimates of overwinter colony losses from all causes have averaged nearly 30% annually since 2006. The precise reasons for honey bee losses are not yet known. USDA and most scientists working on the subject seem to agree that no research conclusively points to one single cause for the large number of honey bee deaths. -
Preventing Pests and Pathogens in Honey Bee Colonies
BestBest ManagementManagement PracticesPractices toto PreventPrevent thethe SpreadSpread ofof PestsPests andand PathogensPathogens inin HoneybeeHoneybee ColoniesColonies Photos by Rob Snyder (used with permission) Many pest and disease problems in managed honeybee hives can be avoided by practic- ing good sanitation and cultural controls. Prevention is the first and best line of defense against organisms that can harm your colonies. Sanitation Tools should be sterilized with flame and scrubbed with isopropyl alcohol after working in or inspecting a hive. Avoid using other beekeeper’s tools that have not been properly cleaned. Clothing and gloves that are exposed to a hive where disease is suspected needs to be scrubbed and disinfected with 10% bleach solution or disposed. If not using gloves, rinse hands with rubbing alcohol then scrub with soap and water after working in a hive that appears to have been infected with disease. When disease is suspected, practice the previously mentioned steps between working hive to hive in the same beeyard. Cultural Controls When purchasing a bee colony, find out if the seller has been treating with antibiotics for patho- gens. Treated colonies could already be infected with disease, even in the absence of symptoms. Never switch frames from a box that is suspected to have pests and pathogens to a box without such problems. Do not purchase or accept used frames, boxes, or other beekeeping equipment that have not been inspected and certified by your county’s bee inspector. Boxes infected with American Foulbrood should be marked with the letters “AFB” followed by the year to prevent unintentional contamination. Equipment that has been infected with American Foulbrood must be treated or burned and buried. -

Introduction This booklet is intended to replace ‘Beekeeping – Making Increase’ published by the Welsh Assembly Government which was itself based on an earlier version produced by the National Bee Unit. The aim of this new booklet is to give more detailed coverage of this important subject and in a form of a practical guide for use by both individual beekeepers and associations who want to become self-sufficient for the provision of new or replacement colonies and queens. The methods described are not designed for large scale queen rearing but should be more than adequate to meet the needs of the hobby beekeepers who, let us not forget, manage about 85% of the colonies in Britain. -
Massachusetts Beekeepers Association's
MASSACHUSETTS BEEKEEPERS ASSOCIATION BEST MANAGEMENT PRACTICES Disclaimer This document is intended solely as guidance. This document does not confer, and is not intended to create legal rights or impose legal duties or obligations. The general descriptions provided here reflect the Massachusetts Beekeepers Association’s current views regarding reasonable considerations for safe and healthy management of honeybees in Massachusetts and may not apply to particular situations based on the circumstances. This document may be revised periodically. Introduction It has often been observed that if you ask ten beekeepers the same question, you will get at least ten different answers. This adage reflects, in part, the great diversity of practice that has grown up around beekeeping. For every beginning beekeeper, there is inevitably another beekeeper, whose enthusiasm to share his or her personal observations and techniques provides the spark for the new beekeeper’s own venture into beekeeping. Diversity of ideas and practices among beekeepers is essential to the continued success of honeybees and beekeeping. Yet, it must also be recognized that beekeepers do not exist separately and apart from the communities in which they live, and as beekeeping becomes more popular, particularly in suburban and urban areas, the potential for misunderstandings with neighbors and local officials also grows. Thus, responsible management of one’s hives within the community in which they are located is also essential. For this reason, the Massachusetts Beekeepers Association has developed these Best Management Practices to provide a framework for determining appropriate, site- specific management practices to promote healthy bees and avoid potential conflicts between beekeepers and others.
