Skillfully assisted bee swarm
In recent summers with a temperature of about 40°C, droughts and high temperatures make it difficult for bee colonies to tolerate. This often results in sharp reductions in bee populations, weak groupings, weak groupings, and even weaker groups. The advantage is that the colony of bees can regulate the temperature of the population as if it were a constant temperature animal. It is in a constant state and does not change with the increase or decrease of the outside air temperature. However, the bee colony's regulation ability is limited, and the beekeeper must comply with the regulation mechanism of the bee colony itself. Conduct management to assist the colony in resisting high temperature and crossing the barriers, protect the strong group, and welcome the next great honey source.
First, the mechanism and behavior of bee colony self-regulation group temperature
The center of the bee colony and child-raising area is maintained at a constant temperature of about 35°C, and the strong group control ability is strong, and the weak group is weak. When the outside air temperature of the colony exceeds 25°C, the heat produced by its own basal metabolism exceeds 35°C. The bee colony begins to cool down. If the outside temperature exceeds 35°C, the bees colony will intensify the cooling. Up to about 40 °C, it is necessary to pour their full power to cool down. At this time, the behavior will be observed as follows: the water bees increase significantly, the entire nest is coated with water, and the bees kiss the water film. Inside and outside the nest, a large number of bee-shaker fans evaporate the water to cool down and make a loud noise. The queen lays eggs to reduce or stop production to narrow the parenting area and reduce the temperature range. If the high temperature lasts longer than the bee colony, the bee colony will abandon the surrounding bees, or even all of them. Only part of the bees and the queen bee will be protected. Bao handsome. The result is that the old bees are exhausted, the young bees are heat-dead, the feed is depleted, all are lost, the strong group weakens, and the weak group changes.
Second, beekeepers follow the biological characteristics of bee colony management measures taken
1.Supply enough water to provide convenient and hygienic water sources for bee colonies: water the site to keep the ground moist and even muddy. Use water from the nest feeder to feed water during the day and night. There is a public water feeder on the floor so that the bees can take water at any time. To save energy, the fans evaporate moisture and cool down, artificially create a moist and humid environment, and improve dry and hot conditions.
2. Beehive Shade: The box is under the shadow of the trees, which is ideal. If there is no condition, cover the beehive with straw mats, hard paper sheets, etc. to avoid sunlight exposure to the beehive.
3. Weak group and strong group: Weak group has poor resilience, 5 bees below the spleen, should be combined with the king, the prisoner Wang cage hanging in the group box or spleen frame above, and then when needed to enable convenient.
4 increase the space inside the box: 8 spleen bee flat box group, only put 7 spleen, leaving enough space for the spleen, bees and then to add more boxes. Always keep a large space inside the box for honeybees to dissipate heat and cool. The space inside the box is the buffer between the colony and the outside world. The temperature is always within the group's childcare area and the outside environment. Big bees are very beneficial to the colony. Increase the spleen spacing is another way to increase the space inside the box, spleen spacing is generally reduced to 9 mm during spring propagation, and the temperature can be increased to 12 mm or more.
5. Prisoner Wangzi: According to the medium and long-term weather forecast, if there is more than one week of high-temperature (36 °C ~ 40 °C) weather, the king can be trapped, actively reduce the burden on the colony, and cooperate with other cooling measures.
6. Opening and closing of the beehive ventilating window: When the high temperature is above 25°C, there is a bee in front of the strong group that cools the fan to cool the fan. At this time, it is necessary to open the window to increase the amount of ventilation, and the outside air flows into the box to cool down. When the outside temperature is higher than 35°C, the ventilation bottom window and top window are closed to reduce the air flow in the nest. Because the bee colony is a natural “air conditioning†machine, the greater the amount of high-temperature gas flowing into the nest, the more the bee colony increases. The greater the burden on thermoregulation, the result is exhausted bee colonies. This is in line with people's rooms equipped with air conditioners. It is a matter of reason to close doors and windows. This is a point where beekeepers are most likely to make mistakes. Special attention should be paid.
