		<li>Prepare 1.5 M sucrose solution by mixing 257 g of sucrose with 500 ml of water (it is easier to dissolve this amount of sucrose in boiling water). Store sucrose solution at 4 &#176;C until use. 
		NOTE: Sucrose solution provides a very hospitable environment for certain microorganisms, and thus easily becomes contaminated and unpalatable to bees. Bulk sucrose solution can be aliquoted and stored at -20 &#176;C until use...

The methods outlined above allow simple, effective and robust treatment of either free-flying or harnessed honey bees. These methods are compatible with many experimental paradigms and biological questions (Table 1). All of the free-flying methods can easily be applied to harnessed bees. The reverse is less successful, however, since temporary restraint and invasive treatment methods can often compromise bees&#39; flying ability.
The methods have been presented from a brain-ce...

Since Karl von Frisch elucidated their dance language1, honey bees have remained a popular study species for researchers in animal behavior and neurobiology. In recent years a myriad of new disciplines have emerged at the intersection of these two fields, and several other disciplines (e.g., molecular biology, genomics, and computer science) have arisen alongside them. This has led to rapid development of new theories and models for understanding how behavior results from activity within nervous systems. Because of the unique lifestyle, rich behavioral repertoire, and ease of experimental and pharmacological manipulation, bees have remained at the forefront of this revolution.
Honey bees are being used to study basic neurobiological questions such as those underlying learning and memory2,3, decision making4, olfactory5,&#160;or visual processing6. In recent years, the honey bee has even been used as a model for studying topics generally reserved for medical research, such as the effects of addictive drugs7-11, sleep12, ageing13, or the mechanisms underlying anaesthesia14.
Unlike for the classical genetic model organisms (e.g.,&#160;D. melanogaster, C. elegans, M. musculus), there are very few genetic tools available for manipulating neural functions in honey bees, although this is currently changing15. Instead, honey bee studies have primarily relied on pharmacological manipulations. This has been very successful; however, the diversity of bee research is such that a range of methods for pharmacological administration are needed. Research with honey bees addresses highly diverse questions, is studied by researchers from different disciplines and backgrounds, and uses a variety of experimental approaches. Many research questions require bees to either be free-flying,&#160;freely interacting in their colony, or both. This can make it difficult to keep track of individual experimental animals, and makes restraint or cannulation unfeasible.
To accommodate the diversity of honey bee research, a variety of drug delivery methods are needed, allowing for robust and flexible administration while ensuring that the pharmacokinetic and pharmacodynamic profiles, invasiveness of the method, and its reliability, suit the paradigm in question. Because of these diverse needs, most research groups have developed their own unique drug administration methods. So far, this has been a strength of the bee research community;&#160;it has led to the development of arrays of methods allowing for administration of the same drug in different circumstances. Our goal here is not to develop a single standardized method for pharmacological manipulations of bees, but rather to highlight methods that have proven to be particularly successful, and help researchers adopt these. We discuss the basic principles of how they work, as well as their advantages and disadvantages.

neuropharmacological manipulation of restrained and free-flying honey bees, apis mellifera

Honey bees demonstrate astonishing learning abilities and advanced social behavior and communication. In addition, their brain is small, easy to visualize and to study. Therefore, bees have long been a favored model amongst neurobiologists and neuroethologists for studying the neural basis of social and natural behavior. It is important, however, that the experimental techniques used to study bees do not interfere with the behaviors being studied. Because of this, it has been necessary to develop a range of techniques for pharmacological manipulation of honey bees. In this paper we demonstrate methods for treating restrained or free-flying honey bees with a wide range of pharmacological agents. These include both noninvasive methods such as oral and topical treatments, as well as more invasive methods that allow for precise drug delivery in either systemic or localized fashion. Finally, we discuss the advantages and disadvantages of each method and&#160;describe common hurdles and how to best overcome them. We conclude with a discussion on the importance of adapting the experimental method to the biological questions rather than the other way around.

A selection of representative results for the methods described above are shown, primarily to demonstrate that the methods allow pharmacological agents to reach the brain and affect honey bee behavior.
Specific effects on brain processes can be easily obtained following thorax injection.
Because pharmacological agents injected through the thorax may act on multiple target...
