Organization and management of mating wasps
The mating colony organizes mating for the small colony that the new queen bee lives, either on the 10th day after the removal or the 7th day after the king platform is sealed.
To organize the mating group, you must first prepare the trunk. The standard beehive can be closely divided into 3 or 4 small areas with 2 or 3 gates. Each community can hold 2-3 nests and spleen, and open 1-3 mm long and 8 mm wide nest doors in different directions. The wall of the box in front of each nest is painted with different colors such as yellow, blue and white, so that the queen bee can identify her own hive. Put a box of capped spleen with baby bees in each district of the box, and a box of honey powder spleen to form a small mating group.
The way to get a lid spleen with young bees is to prepare a beehive, take one or two boxes from each strong colony to seal the spleen, put it into the box, put eight lid lids in a box, cover the lid, and put the hive away from other colonies. After a few hours, the flying bees flew back to their original nest, and most of the lids on the spleen were larvae. The next day, the bees were checked, cut off and then lured into the mature Wangtai. It was safest to use the protective ring made of silver wire to lure into the Wangtai. There is a small cylindrical feeding tube at the lower mouth of the conical Wang Tai protective ring, which cannot be entered from the lower mouth. Because when the bees destroy the king platform, they bite through the king platform wall from the side of the king platform, and then stab the queen bee pupa to death. The protective ring of Wangtai just protects the side wall of Wangtai. The covering of the mating group is directly covered on the upper frame beam of the nest and spleen, and then covered with a secondary cover and a large cover, so that the bees of the adjacent mating group are completely isolated, so as to prevent bees from colluding and biting each other. The mating colony should be placed on the edge of the hive, away from other colonies, where the surrounding space is open and clearly marked, and the two adjacent boxes should be more than 2 meters apart and placed in different directions.
On the 11th day after the worm transfer, that is, the day before the new queen bee leaves the house, the artificial royal platform is lured into each mating group. The induced royal platform should be selected in advance, those that are sturdy and upright should be selected, and then they will be straightened up and glued to the middle of the nest and spleen of each mating group. During operation, the king platform must be kept in a drooping state and avoid shock.
There are few bees in the mating colony, and the ability to adjust and maintain the temperature of the hive is weak, so it is not suitable to be seduced early to avoid delaying the queen's departure from the house. When the king frame is put forward from the king group, the bees can not be inverted and shaken off. A small amount of smoke can be used to disperse the bees around the king platform, sweep the bees with a bee sweep, cut off the king platform on the lath in a warm room, or cut off the triangular iron piece under the king stage, eliminate the small, curved king platform, and lure the sturdy and upright king platform with a protection ring, respectively, or stick the king platform directly to the upper middle of the spleen of the mating group.
The day after being lured into the king's stage, check the queen's room condition, eliminate the dead queen and the virgin queen of poor quality, and immediately fill the back-up king's stage to the Jiaowei group. In order not to interfere with queen bee marriage, mating, try not to open the box inspection, mating group can be observed outside the box to understand the situation. If there are small swarms of bees biting each other in front of the nest or a small number of bees that have been bitten to death, open the box and check. If the queen bee is besieged, rescue him immediately. If the queen bee is not injured, it can be put back into the nest and spleen, and if it has been injured, it will no longer be retained. Mating groups without queen bees can be lured into a royal platform or merged with adjacent mating groups. under normal weather conditions, virgin queens usually mate 3-7 days after leaving the room and begin to lay eggs around 10 days. Therefore, 10 days after being lured into Wangtai, we choose to conduct a comprehensive inspection of the mating and spawning of each mating queen bee before 10:00 or after 18:00. If it is not due to the influence of low temperature and continuous rainy days, the virgin queen who has not mated or laid eggs for more than half a month should be eliminated immediately.
For the mating group to do a good job of heat preservation, shading, prevent bee theft, keep adequate feeding, insufficient should be rewarded feeding, supplement honey spleen. The potential of the cross-tail group is weak, and there are many young bees. Once there is bee theft, they have no defense ability, and it is easy for the queen to be surrounded and injured. When there is a lack of honey sources, we should pay more attention to prevent bee theft and narrow the nest door to only one or two bees.
For the new queen bee that has laid eggs for about a week or so, the queen bee with more eggs and large spawning circle is used to divide the bee artificially or replace the old queen bee to eliminate drones and less spawning queen bees. But for a tiny mating colony organized by hundreds of bees, the new queen bee will take out its eggs in a day or two, otherwise due to lack of spawning status, the queen bee will fly away.

Successful breeding of new silkworm varieties in Hubei
The new silkworm variety "E Bombyx mori No. 3 and E Silkworm No. 4" selected by the Institute of Economic crops of Hubei Academy of Agricultural Sciences (zip code: 430070) won the first prize for scientific and technological progress in Hubei Province not long ago. Compared with Huanghe × Zhaoxia, the main autumn variety in Hubei Province, the strong autumn variety E Silkworm No. 3 has strong resistance, the unified life rate of insect and pupa is more than 92%, and the yield is high, with a cocoon yield of 33.95kg, an increase of 9.94%. The cocoon shell rate is 24.83%, and the length of a cocoon is 1150 meters.

How do racoon dogs come into being and how to prevent them?
Rugged raccoon dogs refer to commercial raccoon dogs that cannot be bred in the breeding period after litter weaning, showing that they are not long, small, bony and shaggy, and can only grow to 2.5 kilograms and 3.5 kilograms in the breeding period. Reason: there are many reasons for the formation of raccoon dogs, generally speaking, there are the following: unreasonable nutrition, nutrition is not full price, which is the main reason for the formation of stiff raccoon dogs. Breeders want to save, only feed corn flour or with very little other feed, because the feed is seriously lack of nutrition, can not meet the needs of raccoon dog growth, resulting in raccoon dog is not long, the formation of stiff raccoon dog.
