CATDOLL : CATDOLL: When wild bees were put on the queen excluder, why did all the bees run away and only one queen was left?

1. When wild bees were put on the queen excluder, why did all the bees run away and only one queen was left?

It must be just a coincidence. The swarm of bees must have planned to flee long ago, and they just happened to see you put up the queen excluder. Because the swarm of bees always have a careful plan before fleeing, and they didn't expect you to put up the queen excluder, so it was just a coincidence!

2. How to kill bee varroa mites?

Methods for preventing and controlling bee mites: 1. Fumigants mainly include anti-mite, anti-mite spirit and anti-mite net. Anti-mite has a good fumigation effect on large and small bee mites parasitic on the body surface of adult bees and crawling on the honeycomb. It is generally carried out in the evening after the bees return to the nest. When the temperature is low in late autumn or early spring, it can be carried out during the day when the bee colony disperses. The dosage is 2 grams for a standard box, 3 to 4 grams for a super box group with more than 10 frames or a horizontal box. First, lay paper on the bottom of the box, put a tile outside the partition, put the medicine on it, and immediately close the nest door and cover the box lid after ignition. After fumigation for 20 minutes, open the nest door, take out the tile and discard the residual ash, then draw paper and burn the mites. The number of times to treat mites is determined according to the degree of parasitism of bee mites and the number of fallen mites. If there are many mites, treat once every 3 to 5 days, and 3 times is a course of treatment. The disadvantage of this drug is that it is easy to hurt young bees, so it is not suitable to use when young bees are leaving the room in large numbers. Miemingling does not harm young bees, but when used in early spring and late autumn, the queen often surrounds the queen. Miemingling has a good effect on killing mites and can be used in spring, summer and autumn. The fumigation time after ignition depends on the temperature. When it is 10℃~20℃, it is closed for 0.5~1 minute; when it is above 20℃, the cover cloth can be opened to release smoke, and the nest door can be opened after a few minutes. This drug is highly irritating and the dosage must be strictly controlled. When the temperature is 20℃, 2 grams are used for a single box group, and 3 grams are used for more than 10 frames. Fumigation is carried out when the temperature is above 15℃ in early spring or late autumn, preferably in the evening after the field bees return to the nest. 2. Commonly used fumigants include sanitary balls, sublimated sulfur and sulfur naphthalene mixture. Sanitary balls have a good effect on preventing and controlling Varroa mites. The method is to grind the sanitary balls into powder, evenly sprinkle them on paper slightly smaller than the bottom area of ​​the beehive, cover the powder with a layer of gauze (to prevent the powder from touching the bees), push them into the bottom of the box in the evening, and collect the fallen mites and burn them in the morning of the next day. The dosage depends on the temperature and the size of the colony. When the temperature is around 20℃, for a colony of 10 frames, 1.5 to 2 grams of medicine is used each time. When the temperature is above 25℃, the dosage is slightly reduced. Fumigation is performed once every 3 to 4 days, and 3 times is a course of treatment. The disadvantage of this drug is that it is easy to hurt young bees, so it is not suitable for bee colonies where young bees are leaving the room. Sublimated sulfur, also known as sulfur flower, is a very fine yellow powder that sublimates at a certain temperature and should be properly stored. Sublimated sulfur is very lethal to small bee mites. The method of use is to wrap 50 grams or 100 grams of sublimated sulfur with two layers of cloth, shake and sprinkle it on the sealed lid comb to prevent the medicine powder from entering the larval room; it can also be sprinkled on the frame beams and in the bee lanes. Sulfur naphthalene mixture is a mixed powder of 70% sublimated sulfur and 30% naphthalene powder. Its usage is to spread paper for fumigation, or sprinkle it on the bee lanes and frame beams. For 10-frame groups, use 5 to 6 grams of medicine each time, do it once every 7 days, and use it continuously for 3 to 5 times.

3. How to raise bees?

Feeding:

1. Supplementary feeding: artificial feeding when nectar sources are scarce. The methods are as follows: ① Supplementary feeding with honey. Honey can be diluted with 20% warm water (crystallized honey needs to be boiled with a little water). The diluted honey can be fed to the bees by gavage or poured into a frame feeder. ② Supplementary feeding with syrup. Syrup is made by adding 50% white sugar to water, which is heated and fully dissolved and then cooled to lukewarm. It is best to add 0.1% citric acid to the syrup to facilitate digestion and absorption. Brown sugar should not be used at this time.

2. Reward feeding: artificial feeding during the bee colony breeding period and bee production period. Generally, a small amount of 60% nectar or 50% syrup is given every other day in early spring, and then once a day as consumption increases. The time starts from 40 days before the nectar flow period until there is a large amount of honey and pollen from the outside world. Each frame of bees can be rewarded with 50-100 grams of syrup each time.

3. Feeding pollen: The purpose is to supplement protein feed. In the late winter and early spring, the pollen saved in the previous autumn can be supplemented, and soybean powder can also be used instead. The feeding method is as follows:

(1) Liquid feeding: Add 10 times the amount of syrup to the pollen, boil it, wait for it to cool, and then put it in a feeding container for feeding.

(2) Cake feeding. Add an equal amount of honey or syrup to pollen or pollen substitute, mix thoroughly, and make into cakes. Wrap them with plastic paper, open at both ends, and place them on the frame beam for bees to feed. This method is often used during cold snaps.

4. Feed water and salts: ① Water. Generally, each bee colony needs 200-300 ml of water per day. Put water in the feeder or put a wet towel on the gauze cover for the bees to collect water. ② Salts. Add 1% salt to the syrup.
