Dear colleagues,


We are proud to invite the members of COLOSS to the workshop on artificial rearing “Method standardization for larval tests”, held in Graz, Austria from 7th June (arrival day) to 9th June 2010. Please register for the workshop as soon as possible, but not later than 25. February 2010 by sending an abstract (about 200 words) to: Notice the scientific agenda below before writing your abstract. Researchers without experience in this technique may provide abstracts describing intended studies. Also notice that only a limited number of attendants (~20) will be accepted. If there are more registrations, active contributors will be accepted preferably. All persons registered in time will receive detailed information about reimbursement, travel, accommodation and scientific programme in March. The costs will be about 200 Euro for three nights in a single room including breakfast and lunch and about 20 Euro registration fee. According to the number of participants the available reimbursement will be about 200 Euro per Person. We suggest you to apply other fundings for your travel expenses. We are looking forward to see you in June in Graz!



Scientific Agenda


The rearing of honey bee larvae under laboratory conditions is an intensively explored method holding many research potentials. The COLOSS network (COST Action FA0803) enables us to center investigators who are developing and refining in-vitro methods and such who apply these method to theoretical and practical questions. At the upcoming workshop we would like to focus on four different aspects.

  • First, we want to discuss the standardisation of protocols and the option of using this method for the risk assessment of plant protection products. This requires the arrangement of ring tests among participating laboratories, as has been done before. Precise questions addressed during this session may sound like: Does the variance within season, among colonies or different strains of honey bees influence the reliability of standardized methods? What further steps are necessary to promote the use of this method? The outcome of this might be contributed to the BEE BOOK.

  • Second, there should be the opportunity to focus on technical aspects and trouble shooting. What are the most commonly used protocols, modifications and problems. Key questions may be the creation of aseptic environments, or how to obtain a homogenous population of larvae of defined age.

  • Third, we should consider the quality of produced workers. In-vitro rearing alters developmental dynamics of larvae and influence the worker quality by different means. Interesting questions in this session are: Do our methods produce workers comparable to those reared under natural conditions? How do we have to consider alterations?

  • Fourth, we will talk about research applications. Artificially reared larvae are ideal models to study the effects of pesticides, pathogens, growth and metabolism, genetics, nutrition or rearing environment.

To balance the core areas of the workshop we ask all participants to indicate in their abstract which topic meets their interests and what they can contribute.
