CATDOLL : CATDOLL: What should we do if bees stop working because they are harassed by hornets?

1. What should we do if bees stop working because they are harassed by hornets?

There are many types of hornets, and the main two types that harm Chinese bees are large hornets and small hornets. When beekeepers find hornets attacking small bees (identifying bees by the behavior of guard bees at the nest entrance), they should take the following measures to prevent hornets from harming Chinese bees.

1. In the summer and autumn when wasps are rampant, the apiary should be inspected several times a day. When the weather is not too hot, try to close the small nest door or use a single nest door. In addition, the wasps that come to prey should be killed with a swatter or driven away.

2. If there is a hornet's nest near the apiary, you can insert several wooden sticks covered with DDT into the hornet's nest. Hornets have the characteristic of flying away immediately when frightened, so you can drive them away. You can also ask a master who dares to catch hornets to catch them.

3. In areas where there are hornets, in addition to destroying hornet nests and killing the hornets that come to hunt, the nest entrance should be nailed into a fence shape with iron nails to prevent the hornets from biting through the nest entrance and entering the hive.

2. How to prevent wax moths and wasps from harming bees?

There are two common wax moths that harm bee colonies: the greater wax moth and the lesser wax moth. The larvae of wax moths are also called nest moths. They harm honeycombs, destroy beehives, harm bee larvae and pupae, and cause white-headed pupae. You can eliminate old honeycombs and melt wax in time, clean the wax scraps on the inner wall and bottom of the hive regularly, keep the hive clean, and do not give nest moths a breeding ground to prevent wax moths. In bee colony management, it is necessary to raise a strong colony so that there are more bees than honeycombs, so that bees can protect honeycombs and prevent nest moths from harming the honeycombs. Remove honeycombs from the bee colony to prevent nest moths from harming the hives. Drugs can be used to prevent and control them. ① Carbon disulfide: For each super, put 8 to 9 honeycombs, use 3 ml of the drug, drip it on thick paper, place it on the frame beam, and fumigate for more than 24 hours. ② Sulfur dioxide: It is the smoke produced by burning sulfur. Each super box is equipped with 8 to 9 spleens. According to the dosage of 3 to 5 grams of sulfur, the medicine is placed on the tiles of the empty nest box and fully burned. The fumigation is sealed for more than 24 hours. Fumigation is repeated after 7 days.

There are many kinds of wasps that harm bees, among which the most ferocious are the large and small wasps. The large wasps can not only intercept flying worker bees, but also wait in front of the entrance of the bee nest, biting a large number of bees entering and leaving the nest. The small wasps are more agile than the large wasps when catching bees. Although the small wasps do not prey on many bees, they seriously interfere with and destroy the normal life of the bee colony, causing losses to production. Destroying the wasp nests around the bee farm is a key measure to eradicate the harm of wasps. To destroy the wasp nest, you can capture the wasps and apply medicine to them, and then contaminate the nest after releasing them, thus poisoning their companions. The specific method is to capture the wasps with an insect net, lure them into a wide-mouthed ordinary bottle of about 100 ml, and immediately cover the bottle cap. The bottle is pre-placed with about 1 gram of powdered medicine for killing wasps. The wasps in the bottle automatically apply the medicine to various parts of the bee body due to the flapping of their wings. The bottle cap is opened to let them return to the nest. The powder brought back by the returning wasps quickly contaminates the entire nest, achieving the purpose of destroying the wasp nest. Commonly used drugs for killing hornets include organochlorine insecticides such as lindane and chlorpyrifos, and organophosphorus powders such as trichlorfon, parathion, and methyl parathion.

According to the dosage of 3 to 5 grams of sulfur, the medicine is placed on the tiles of the empty nest box and fully burned. The closed fumigation is carried out for more than 24 hours. Fumigation is carried out again after 7 days. There are many kinds of wasps that harm bees, among which the most ferocious are large and small wasps. Large wasps can not only intercept worker bees flying in the air, but also wait in front of the entrance of the apiary nest, biting a large number of bees entering and leaving the nest. Small wasps are more agile than large wasps when catching bees. Although small wasps prey on a small number of bees, they seriously interfere with and destroy the normal life of the bee colony, causing losses to production.

3. How to eliminate hornets?

Wasps are major enemies of honey bees, especially large hornets. Once they become rampant, the losses they cause to us are immeasurable.

The way to eliminate wasps is to capture and use drugs. When catching, use iron wire to make a circle, put a fishing net on it, and connect a 1.5m long wooden or bamboo handle to the iron circle to make a wasp catching net. When the wasp attacks, cover it with a net cover so that it will not kill the bees. Use a brush dipped in poisonous liquid to apply it on the back of the wasp and let it return to the nest. Other wasps will lick the liquid and die of poisoning; you can also use bait, cut off drone eggs or pork, cattle, frogs and other meat, chop them up, mix them with an appropriate amount of furadan, put them in a container and scatter them around the bee farm, but pay attention to the safety of livestock and poultry. Wasps will bring poisonous food such as drone eggs or meat back to the nest to feed their larvae. This will greatly weaken the power of the wasps. When we catch a wasp, tie it around the waist of the wasp with colorful lines, then loosen it and observe where it flies. Doing this a few times will find the wasp nest, but it is a bit troublesome. After the nest is found, burn the hornet nest with hay doused with gasoline at night to kill the whole colony. Some hornet nests are high on tree branches, so you can connect them with several long poles and push a small bottle of dichlorvos into the nest, and the hornet nest will be destroyed.

The best way to eliminate wasps is to prevent them from spreading in summer and autumn, that is, to eliminate them before they start to spread, so as to achieve the effect of cutting the grass and eradicating the roots. Although wasps are social and gregarious creatures, they are not highly social and gregarious creatures like bees. Wasps also have a solitary period. After hibernation, wasps have a single queen bee to build nests and lay eggs. In the early stage, these wasp queens not only have the responsibility of reproduction, but also have to take charge of nest building and feeding. This time is exactly when wasps appear sporadically. According to the life characteristics of hornets, if we eliminate them as soon as they appear, the hornet population is generally not strong at this time. If we kill a large number of worker bees, it is very likely that the larvae of the hornets will starve to death. The biggest advantage is that when the hornets have just built nests or are looking for nesting sites, they do not have larvae or nests. In other words, the queen bee is looking for a residence. If we eliminate the hornets at this time, we are very likely to eliminate the queen bee. At this time, there is either no hornet nest or only larvae. If we eliminate the queen bee, the larvae will die in the end. If there is no nest, we have eliminated a nest of hornets. It can be said that we have achieved the effect of cutting the grass and eradicating it completely. It saves time and effort compared to eliminating the hornets after they are rampant.

Common methods for eliminating wasps:

1. The best time to kill wasps: 6 to 9 am and 7 pm. Wasps have good eyesight and love light. They are active and active during the day and stay at home at night. Therefore, we should avoid killing them during the day. The light is dim, the temperature is low, and the air is humid in the early morning, dusk, and night. Wasps move relatively slowly, which is the most suitable time to kill them.

2. Common methods of killing hornets: Based on the habits of hornets, characteristics of the hive and on-site investigation, the following methods are mainly used to kill hornets.

(1) Bag method:

It is suitable for small and easily accessible single beehives such as balconies, eaves, and under awnings. The trappers need to prepare cloth bags or plastic bags larger than the beehive in advance, approach the beehive in the best way under the premise of taking safety precautions, first spray the beehive exit and the bee colonies outside the nest with insecticide (DDV or gunner), then cover the beehive with a woven bag and quickly tie the bag mouth, then remove the beehive, throw the beehive and bag into the water, bury it underground, or pour gasoline on it and burn it. The nest should be removed at night or on rainy days.

(2) Fire Power Method:

For beehives built at high places that are difficult for people to approach, you can tie a piece of waste cotton soaked in diesel or gasoline on one end of a long bamboo pole, light it, and stretch it to the side of the beehive to burn it from bottom to top. Evacuate the surrounding people in advance and pay attention to fire prevention.

(3) Killing with drugs:

① Use a cloth strip, towel or cotton to dip in pesticide (DDV or Dimethoate) and hang it on the beehive or insert it into the beehive to fumigate the bees.

② Automatic drug application method: After catching a wasp, put it in a 100-150 ml bottle with "Nest Destroyer" powder pre-placed in the bottle. With the help of the airflow of the wasp's wings, the powder is automatically and evenly applied to all parts of the bee's body. Open the bottle cap and let the bee return to the nest. The whole nest can be quickly contaminated to achieve the purpose of destroying the nest. Be careful to prevent corrosion or poisoning of the drug.

(4) Local methods of killing:

The equipment of the traditional bee-killing team mainly consists of a pair of waders, a thick raincoat, a pair of thick long gloves, a fully enclosed helmet, and an oil torch. They conduct field surveys and formulate specific bee-killing plans during the day, and burn with torches at night. This method of bee-killing is simple, easy, low-cost, and effective.
