Necessity
The giant bees have been breeding in bee colonies since spring propagation. With the growth of bee colonies, the number of worker bees increases rapidly. The relative proportion of bee bees and bees is stable, and generally it will not cause devastating damage, and the group shrinks before autumn. The relative increase in the number of large bee stings has exacerbated the damage. In recent years, the small bee pupa has also been erupted in July and August. The harm is more serious than that of the big bee pupa. If the infestation occurs before the fall, two species of bee stings harm the bee larvae and adult bees. Not only will the number of overwintering bees fall drastically in autumn, the living bees will not be robust and their life span will be short, and many will not live through the harsh winter. The overwintering bees that live to the spring season are extremely low in feeding ability. Bee colonies often break the bees during the winter, or cause paralysis. The size of bee stings parasitizes the body surface of adult worker bees and sucks the hemolymph of adult bees. As a result, worker bees are reduced in physical constitution and lifespan is shortened. What is more serious is that in the breeding stage of bee stings, the female sturgeons of large and small stings are immersed in their nests before the bee larvae are capped. The body fluids sucking the big larvae are nutritious, and the progeny are propagated so that the bee larvae do not develop smoothly, and they are barely developed as The larvae are also weak and physically disabled. They are not able to normalize their feathers. Many of them become dead crickets. The dead bees are bitten by the worker bees and dragged out of their nests to form spleen.
During spring, summer and autumn, the bee colony breeds uninterruptedly, and the larvae continue to be kept in the nest room. The bees and cubs in the closed nest house play a protective role against the locust. The pesticide cannot prevent the inside of the house cover. The locusts must be kept prisoners for at least 10 days. After all the locusts have been exposed, they can be thoroughly treated to breed a sufficient amount of robust, pest-free, age-old winter bees. This is a one-year plan for autumnal breeding. Necessary steps. Qiufan is the beginning of the beekeeping year and is the basis for safe wintering. It is the guarantee for successful spring propagation and is the hope for the harvest of the thorn honey.
2. The timing of the king
According to the local climate and the conditions of powdered flour sources, in the central and western regions of Shandong Province, it will generally begin around August 20th, and push forward with 10 days in advance.
3. Control methods
Due to the different sensitivities of the two kinds of pupae to the drug type, they must be mixed for a short period of time. For example, small pupae are suitable for "sublimation of sulphur" control, and large pupae are suitable for controlling with pharmacological agents. Mix the two drugs first and then apply them so that they can be treated during the short break period.
(1) Mixing ratio: 50 g of sublimed sulfur, mixed with one (1 ml) killing scorpion No. 1 (Jianjing No. 3, etc.), and applied immediately after mixing.
(2) Dosage: 5-7 grams per group of bees, 7 groups below the spleen with a small amount, many with a large number. (3) Method: Spread evenly on the spleen frame in the spleen road. (4) Number of times of application: Generally, it is twice. When the prisoner and the king are applied at the same time, when the king or new king is spawned, it is also applied once again when the autumn is in full bloom, so that the mites hidden under the wax cover are Avoiding the last application also avoided the two applications.
In order to prevent leakage of the bees, three days after opening the complex, two pieces of each group were hung in the inner corners of the spleen on both sides of the nest.
4. Prevent disease
At the same time as the opening ceremony, combined with the prized syrup, feed "PPA" 1 tablet / 1 kg syrup and "Rhubarb soda" 2 tablets / 1 kg syrup. To prevent the highest incidence of spiroplasmosis and sporangiasis, while "Rhubarb soda" also helps digestion.
5. No prisoner Wang Zhiyu Yu Wangfa
Divide a production group into two districts. All sub-spleens will be placed in the box, and the rest of the spleen will be placed in the nest box. Note that the queen bee must stay in the nest box, cover the double board and cover the cloth. The nest box can not pass through the box, and the box can be left behind. Nest door. On the afternoon of the next day (when the field bee is fully returned to the nesting box), Shi Shenghua's sulfur and water-repellent agent mixture is applied in the nest box, followed by mature Wangtai in the box. After the new king spawns, the nest box and the box full Apply the mixture and apply the medicine after sealing the lid. Afterwards, the group will grow in autumn.
