The COLOSS BEEBOOK, Vol I Standard methods for Apis mellifera research ¿ Vincent Dietemann, James D. Ellis, & Peter Neumann (Eds) The COLOSS (Prevention of honey bee COlony LOSSes) BEEBOOK is a unique venture that aims to standardise methods for studying the honey bee. It is a practical manual intended for scientists, extension specialists and beekeepers, compiling standard methods in all fields of research on the honey bee, Apis mellifera. The first two volumes are composed of 32 peer-reviewed chapters authored by more than 234 of the world's leading honey bee experts from 34 different countries. Since their original publication in 2013, the BEEBOOK has become the definitive bee research manual, and the original papers have been downloaded some 180,000 times and cited in more than 2,300 scientific papers. The hard copy volumes have proved invaluable at the laboratory bench. Volume I includes approximately 1,100 separate protocols dealing with the study of the honey bee, Apis mellifera. These cover anatomy, behavioural studies, chemical ecology, breeding, genetics, instrumental insemination and queen rearing, pollination, molecular studies, statistics, toxicology and numerous other techniques.
