The three main insect pests and control methods of "soil bee" Chinese honeybee!

Breeding Chinese honeybee is one of the ways to increase farmers' income in mountainous and semi-mountainous areas. in the process of breeding, pest control is the key link of increasing production of bee products. here are the three main insect pests and control methods of "local bee" Chinese honeybee!

1. Nest worms

The nest worm is the larva of wax borer and the main enemy of Apis cerana. It feeds on wax chips and eats the nest spleen so that the bee larvae can not be covered at pupal stage or produce "white-headed pupae", and cause mass escape or death of large numbers of capping pupae.

Prevention and cure method

1. Strengthen colony management: raise strong colonies, that is, keep sufficient honey and powder on the nest and spleen at any time, and select high-quality queen bees to enhance the genetic advantage in the hive, improve the colony's ability to resist diseases and insect pests, replace the new spleen in time, and eliminate the old spleen, which can effectively eliminate the living space of honeycomb insects.

two。 The method of killing insects and eggs: from late November to early December and from early March to early April of the following year, the beehive is thoroughly cleaned, the box body is thoroughly cleaned, and the bottom of the box is irrigated with boiling water to kill the eggs; in the coldest period of winter, the box spleen is placed in outdoor frost, it can also kill nest eggs and larvae. In summer and autumn, when the bee colony is harmful to the nest insect, the bee pulls out the damaged lid spleen and after 5-15 minutes in the sun, the nest worm will climb onto the spleen and kill it with tweezers.

3. Drug control: soak the beehive and empty nest spleen with 5% lime water or 1% caustic soda solution for 30 hours, then wash and dry, which can eliminate the hibernating nest insects. About 10 star anise fruit in each box can also play a role in preventing the breeding of nest worms. For bees that suffer from serious harm to the nest insects, you can use the "nest worm net" drug to kill the nest worms. Take 5 grams of nest insects net and dilute it to 1.5 liters with water. Spray the nest and spleen, dry and save.

2. Wasps

Wasps are commonly known as wasps, omnivorous beneficial insects, but the natural enemies of honeybees, the Chinese honeybees collected from July to October every year, are eaten by wasps, which can seriously cause the Chinese bees to flee or be killed by the whole nest.

Prevention and cure method

1. Leave a small opening in the hive: do not have an open part of the hive. The opening of the nest door should be as small as possible. It is best to use a round hole. Do not let wasps invade the Chinese honeybee hive.

two。 Keep enough honey powder: artificially reduce the collection of bees out of the nest and reduce the predation chances of wasps.

3. Manual removal: artificial beating of wasps at 8:00-10:00 in the morning and 6:00-7:00 in the evening, looking for wasp hives, painting the back of wasps with "nesting spirit", putting wasps home, polluting the whole nest and killing wasps.

III. Ants

Ants climb into the beehive to kill bees, absorb honey from the hive and spleen, and lay eggs on the beehive and cover cloth, making the colony unstable.

Prevention and cure method

1. Cut off the ant path into the hive: clean the weeds around the hive, raise the 10cm of the hive, put the hive's four legs into a container that can hold water, and then inject water into the container to cut off the ant crawling path.

two。 Artificial elimination of ants: you can use termite net to kill, find the hole of the ant nest, put the net termites into the ant nest, and kill the whole nest; soak tobacco leaves and water in the proportion of 1:1 for 15-30 days, pour the soaked tobacco water around the beehive, if soaked in bitter fruit, the control effect is better.

The above is the introduction of the pest control technology of Apis cerana.
