Study on the Effect of Bee Strain and Pollination Method on the Hygienic Behavior of Honey Bee Colonies Tested by Liquid Nitrogen Freezing Method

Abstract

Bee queen breeding was conducted for local and Carniolan honey bee strains, as well as hybrids resulting from cross-pollination, using both natural and artificial insemination methods. The hygienic behavior test was conducted using liquid nitrogen freezing method. The results showed that the hybrid bee strain T3 outperformed with detection and removal rates of 92.66% and 87.50% respectively, 48 hours after the study, regardless of the insemination method. The results also demonstrated the superiority of the natural insemination method, regardless of the studied strain, with detection and removal rates of 85.66% and 78.66% respectively, 48 hours after the killing process. The results also showed the interaction between the bee strain and the insemination method, 48 hours after the killing process, with significant superiority for treatment T2A1 in terms of detection and removal rates at 98.00% and 96.66% respectively. It was followed by treatment T3A2, which had no significant difference in detection rate (94.33%) and a removal rate of 89.00%, which was not significantly different from treatment T3A1 with a removal rate of 86.00%.
