Nest worm refers to the larvae of the wax borer, there are two common species of adults and larvae, the nest worm body length is about 3 cm, and the larvae are about 2 cm. 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.
Wax borers generally appear in March to April, lurking inactive during the day and active at night, with females and males mating at night, and then sneaking into the hive to lay eggs, which are laid in the crevices of the hives or at the wax chips at the bottom of the box. The newly hatched nest insects do not like to live on wax chips at the bottom of the box, but try to drill into the nest spleen of the bee colony, and the worker bees who protect the spleen do not obstruct their movements, so the larvae take the opportunity to drill into the nest spleen. After the larvae enter the spleen, they lurk at the bottom of the nest room and bite the nest spleen into a tunnel, causing the bee "white-headed pupae" disease. When the larvae develop into 5 to 6 days old in the nest spleen. Due to the length of the body, the amount of food is getting larger and larger, and the destructive force of the nest spleen is also increasing, at this time the worker bees feel their threat, begin to remove the "white-headed pupae", and whistle the nest spleen of the insects, pull the nest worms out, and some fall to the bottom of the box and survive by eating wax chips. At this time, the worker bee will never let the grown nest worms go to the nest again.
If the bee colony is weak, there are many nest worms in the spleen, and the worker bees cannot resist, and the bee colony has to abandon the nest and flee, and move to a new location to build a nest. The original hive was endangered by the nest worms, and after a few days the entire nest spleen was eaten clean, and the larvae grew up to spit silk into a net, and formed cocoons in the net to pupate. The pupae feathers turn into adults, and the wax moths lay eggs after mating, and so on.
Many friends found that there is a "white-headed pupae" on the nest spleen and did not see the nest worm at the bottom of the box, they all feel that it is not caused by the nest worm, and they do not know that the nest worm at the bottom of the box is cleaned up by the worker bees after growing up on the spleen.
The articles on the market to prevent nest insects are nest insect clear wood chips and nest insects a spray net, the main ingredient is Kang Kuan, wood chips are soaked Kang Kuan to get, nest worms a spray is diluted by mixing water to a certain proportion, the commonly used proportion is 2 times, that is, 2 ml Kang Kuan with 1 liter into 2 kg of water is converted into 2 kg of water, 5 ml of Kang Kuan on the market can be converted into 5 kg of water.
Kang Kuan's principle of action activates the fish nittin receptor in insect cells, binds to it, causing the receptor channel to open abnormally for a long time, thereby over-releasing calcium ions in the cell, resulting in paralysis of insect muscles, and finally paralysis and death.
If the bees are raised less, you can choose the nest insects prepared by the manufacturer to spray clean or the nest insects to clear the wood chips. When you have a large bee colony to buy a mixed finished product is more costly, at this time we can choose to buy a pack of 5 ml of Kang Kuan, add 5 pounds of tap water to dilute it with water to 2 times thousandths, spray wet on the inner wall of the hive, sand cover, large cover, covering cloth, can effectively prevent the breeding of nest insects, the effect is very good and the cost is very low.
When waxing is drilled into a beehive to lay eggs or hides on a sand cover or large lid to lay eggs, due to the spraying of Kangkuan dilution on the wall and lid of the box, the larvae of the wax meditation cannot hatch normally or the wax meditation dies
Kang Kuan is a micro-toxic grade, very safe for pesticide practitioners, and also very safe for beneficial insects (bees), fish and shrimp in rice fields, but for moths, silkworm moths are highly toxic, such as silkworm babies, nest worms, drill heartworms and so on.
