Influence of wintering temperature on the state of the antioxidative system in Apis mellifera L.

The state of the antioxidant system protection honey bees Apis mellifera carnica under action different temperatures in order to optimize temperature regime keep bee colonies indoors during winter was studied. Bee 81–91-day-old worker were transferred from territory Yuriy Fedkovych Chernivtsi National University apiary period sharp changes (the end November) constant conditions buildings (5±0.6°С and 14±0.8°C) kept there for 12 weeks. selection biochemical analysis performed 7 times every two level TBA-active products (TBARS), catalase (CAT) glutathione-S-transferase (GST) activity insect tagmas (head, thorax abdomen) It has been found that transfer unstable stable ones, regardless their value, leads a decrease flow rate lipid peroxidation (TBRAS level) against background increasing enzymes (CAT та GST). tagmospecific response depending on wintering revealed. Keeping at (for ten weeks) accompanied by certain coherence work insects. In particular, TBRAS level, as well enzymes, did not change significantly study. However, early February (at experiment), building temperature, TBARS increased tissues bee’s head, abdomen GST intensified. At same time, middle (on January), bees, +5°С, lower comparison with wintered +14°С. optimal keeping proposed: medium strength around weak +14°С January further +10°С.
