4.4.8. Protocol for using a dead bee trap

  1. Equalise colony size or assess colony size (see the BEEBOOK paper on colony strength (Delaplane et al., 2013) to obtain a mortality rate. Do regular size assessment if it is a long term experiment.
  2. Connect the trap to the hive for several days before the experiment begins, to allow the bees to become used to the new addition.
  3. Remove and count the number of dead bees at regular predetermined intervals.
  4. Clean the trap if necessary after counting.
  5. Calculate the corrected mortality rate based on the recovery rate determined in section 4.4.7.) (Gary, 1960):
