Sažetak
In order to evaluate genotype-environment interactions of honey bee vitality and colony losses, international experiment with 621 honey bee colonies from 18 genotypes in 16 test apiaries across Europe was launched in 2009. No chemical treatments against Varroa destructor and other diseases were applied since 2011. Beside testing and evaluation of colony development, productive traits and diseases incidences in the experimental colonies, we additionally have evaluated swarming, defensive and hygienic behaviour. During regular seasonal censuses, a four point graduation scoring system was used for the evaluation of the first two behaviour traits. Additionally, for estimation of hygienic behaviour, field test (pin-test) was used at least two times per active season. In the first complete season (2010) 419 colonies, 67.5% from the total number of 621, were assessed for defensive and swarming behaviour. During the regular seasonal censuses in the following year, 136 colonies or 21.9% were assesses for both mentioned traits. Regarding the hygienic behaviour, 314 (50.6%) colonies out of starting 621 colonies, were tested and evaluated in 2010. However, due to the low survival rate in the following 2011, pin test was applied only on 121 colonies (19.5%). The preliminary results from the statistical analysis of the observed ethological traits show strong genotype, environmental and seasonal influence. Additional rate differences for hygienic behaviour appeared as a consequence of application of various time intervals (8, 12 or 24 hours) for estimation of percentage of unsealed and cleaned cells. These preliminary results indicate high relevance of different environmental conditions on expression of pointed ethological traits in the tested honey bee populations. Also, there is a strong indication of wide range of interactions between mentioned conditons and the tested genotypes.
