RT Journal Article SR Electronic A1 Přidal, Antonín A1 Svoboda, Jiří T1 Queen introduction into the queenright honey bee colony JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 58 IS 5 SP 307 OP 312 DO 10.11118/actaun201058050307 UL https://acta.mendelu.cz/artkey/acu-201005-0035.php AB One of the actual elementary biologic principles of the introduction of queen is that the recipient colony has to be queenless. We accidentally found that a queen can be accepted also in queenright colony with using of the queen excluder. Therefore, we conducted two experiments with the introduction of queen in queenright colony.Under defined conditions of the experiment and with application of the queen excluder as a separator of queens we successfully introduced queen in the queenright colony. This result is discussed in relation to the general principle that a queen should be introduced only in a queenless colony. It is possible that there are some exceptions advert to the existence of some unknown biologic patterns in the honey bee biology and pheromones.
