Abstract :

Defence behaviour (sting test), hygienic behaviour (needle test) and syrup foraging rate were
studied in honey bee (Apis mellifera) colonies artificially made up of defensive and gentle bees (1:1), and were compared with homogenous colonies made up only of either defensive or gentle bees. The defensive bees turned out to be high-hygienic whereas the gentle bees were low-hygienic. The mixed colonies were defensive in terms of time to the first sting, but gentle or intermediate in terms of the number of stings. Colonies of mixed high-hygienic (defensive) and low-hygienic (gentle) bees were found to be intermediate or high-hygienic when they were monitored after a period of 12 or 24 h, respectively. Foraging rate was also markedly differentiated in homogenous colonies. The colonies with a mixture of good and poor foragers exhibited a poor foraging rate. Repeatability of the monitored traits was higher in the 100% defensive/high-hygienic colonies (higher genetic effect) than in 100% gentle/low-hygienic colonies. Efficient workers performed tasks by themselves and did not solicit help from non-efficient workers. Results of combining of different bee types occurred different. Interworker interactions were mostly non-additive for foraging and defensive behaviour, but additive for hygienic behaviour.
