First, bee stings harm symptoms
The bees that have been parasitized by bees are stunted, they are debilitated and their life span is shortened. In severe cases, they die when the larvae have not been dying. Some larvae, although capable of phlegm, do not eclosion and die in their nests; some are not fatal, but The larvae that have left the house are either winged or wingless. They crawl around in front of the box, and their gregariousness rapidly declines, causing the death of the whole group or the destruction of the whole apiary.
Second, control methods
Must seize the bee colony overwinter before the broken period and the early spring without the lid of the spleen to use two critical periods for complete prevention and treatment, because at this time bee parasitoid on the adult body, no place to hide, easy to kill. In early spring, it is best to treat the lice at high temperatures at noon. Minimize the number of warts in breeding and production seasons. No matter what drugs are used for treatment, it is advisable to try them in 1 to 2 groups first, depending on their effects, whether or not to conduct prevention and control in the whole room. In the early spring and late autumn, larvae are treated with contact and fumigants, and fumigants are used during the production season.
1. Smoke smoke agent. Propaganda, extermination smoke smoke agent, kill the net smoked smoke agent. The parasitizing fuming agent has a good effect of killing large and small bee stings on the surface of adult bees and crawling on the spleen, generally after the bees come back to the nest in the evening; when the temperature is low in early spring or late autumn, It can be done during the day when the bees swarm. Use a dose standard box of 2 grams, 10 boxes or more of the box group or horizontal box with 3 to 4 grams. First, put the paper on the bottom of the box, place a tile outside the partition board, place the medicine on it, and immediately close the nest door to close the lid. After 20 minutes of smearing, immediately open the nest door, remove the tiles and discard the ash, and then inhale the paper (or you can incinerate the paper the next morning). According to the degree of parasitism and the number of falling bees, the number of warts should be decided, and the number of warts should be increased. Every 3 to 5 days should be treated once, and 3 consecutive times. The disadvantage of this medicine is that it hurts young larvae, so don't use this medicine when larvae are out of the house. Extermination and use of fumigating agents are the same as above. This medicine does not injure the young bees. However, in the early spring and late autumn, the phenomenon of encircling the king sometimes occurs. Killing net smoked smoke killing effect is good, spring, summer and autumn are available. After the ignition, the treatment time depends on the temperature. At 10 to 20°C, it is closed for 0.5 to 1 minute; at 20°C or above, the cover cloth can be lifted and smoked, and then the nest door is opened after a few minutes. The drug is irritating and the dosage should be controlled. When the temperature is 20°C, use 2 grams in a single box group, 3 grams in 10 boxes or more, smoke in the early spring or late autumn when the temperature is 15 to 12 or above, and be suitable for field bees in the evening. Go back to your nest.
2. Fumigant. Commonly used health ball (naphthalene), sublimed sulfur and sulfur naphthalene mixture and so on. Sanitary balls are effective for preventing and controlling large bee stings, and are commonly used. The method is to grind the hygienic ball into a powder and spread it evenly on the paper that is slightly smaller than the bottom of the beehive. A layer of gauze is covered on the medicine powder (to avoid touching the bees to kill the bees), and then pushed into the bottom of the box in the evening, the next day. In the early morning, the paper is collected and discarded. The dose depends on the temperature at that time and the size of the group. The temperature is about 20°C, and the population of 10 boxes is 1.5 to 2 grams each time; when the temperature is above 25°C, the dose should be reduced slightly. Every 3 to 4 days fumigation 1 time, 3 times for a course of treatment. The disadvantage of this medicine is that it can easily injure the larvae, so the young bees are temporarily out of medicine when they are out of the house. Sublimation sulphur, also known as sulphur, is a very fine yellow powder that sublimates at a certain temperature and should be properly kept. Sublimation of sulfur is very lethal to the stingray. Usage is to use two layers of cloth 50 grams or 100 grams of sublimed sulfur, shake on the cover spleen (to prevent the drug into the larvae room), can also be sprinkled on the beam and the bee. Sulfur naphthalene mixture is a mixed powder of 70% sublimed sulfur and 30% naphthalene (hygienic ball) powder. The usage is paper fumigation (same as ball powder) or sprinkled on the bee and frame beams. Each frame of the 10 groups is 5-6 grams, once every 7 days, continuous control 3 to 5 times.
