I believe that many family beekeepers have encountered such a problem, domestic bees are very easy to escape, and do not know the reason. Before the bees escaped, the hive was covered with white silk, as if there were bugs in it. This phenomenon is typical of nest insect hazards.
Nests are the larvae of the wax borer of the moth family, which will fly to the hive nest spleen or the bottom of the hive at night to lay eggs, and the adult nest worms will eat the wax residue at the bottom of the box or the nest spleen. Severe on the nest spleen will cause the bee larvae to die due to inability to cover normally, and the recent absence of a cap causes the bee to abandon the spleen and escape.
If we want to do a good job in preventing nests, we must understand the living habits of nest insects, and it is much better to prevent accidents in advance.
After the death of the bee pupae endangered by the nest insect, the bee will gnaw on the cover of the bee pupa, and we will see the picture of the dead larvae of the bee, the white-headed pupae, which is typical of the banded and linear whitehead pupae
Find the nest worm on the bee spleen that is infested by the nest worm, and then use forceps to clip out the picture and clean the nest worm on the bee spleen. After this bee spleen is seriously harmful to nest worms, the bee spleen is spit out a lot of cotton-like silk mesh by nest worms
Nest insects are one of the main enemies of the colony and can be harmed all year round, especially in the hot summer. Nest worms are the larvae of wax borers, and there are two common species of adults and larvae. Adult nesters are about 3 cm long and larvae are about 2 cm long. Nest worms reproduce quickly, eggs and larvae are very viable, and the harm is extremely high. It mainly harms weak bee colonies and makes cocoons at the bottom of the nest room, makes tunnels in the nest spleen to damage the nest spleen and moth wax on the nest spleen, and harms bee larvae and bee pupae. The victim bee colony is mild and has autumn decline, which affects the yield and quality of honey, and in the heavy case, it can cause the bees to abandon the nest and escape, resulting in losses. Therefore, during the summer period of the bee colony, it is necessary to do a good job in the prevention and killing of nest insects.
1. Pay attention to the breeding and management of the bee colony and increase the defense ability of the bee colony against the nest insects
Since nest insects are mainly harmful to weak bee colonies, it is necessary to manage the bee colony when the summer comes, so that it changes from a weak group to a strong group, and enhances its ability to defend against nest insects.
2. Remove the old nest spleen and reduce the environment that may induce nest worms
In the summer, the old nest spleen should be removed to make the bee spleen commensurate, and the bees should gather to protect the spleen and resist the nest insect hazard. After the old nest spleen is withdrawn, it should be waxed in time and should not be placed for a long time, so as not to cause nest insect harm.
3. Cultivate strong swarms to enhance the resistance of bees to nest insects
The main target of nest insect pests is weak bee colonies. If a strong herd can be bred, the resistance can be greatly enhanced and the nest insect pest can be prevented or mitigated. Weak groups should be merged in time.
4. Clean the hive so that the nest worms have no room for development
Do a good job in the cleaning and hygiene of the nest box, clean the beehive frequently, remove the wax chips and residues in the box in time, eliminate the breeding ground of the nest worms, and create a good living environment for the bees. The storage nest spleen should be sealed tightly and smoked with drugs on a regular basis.
In order to better prevent nest insects, we must strengthen the management of bees, remove wax slag at the bottom of the hive, eliminate the nesting insect production environment, and cut off its reproductive pathways. Usually, it is necessary to change the new spleen and replace the old nest spleen, which can also effectively prevent nest insects. When there is time, the hive can also be swapped out and baked with a musket, which can both play a disinfection role and kill the nest eggs.
