What are the key points of breeding and management of yellow powder insects in winter?

Tenebrio Molitor is favored by many farmers because of its high protein content. It makes the "pests" living in the warehouses of crops, grain and medicinal materials become people's favorite high-nutritious food in the twinkling of an eye, and more and more people are raised in recent years. It is more difficult to cultivate Tenebrio Molitor in winter. Let's take a look at the key points of breeding and management of Tenebrio Molitor in winter.

First, what are the main points of winter culture and management of yellow powder insects?

1. The house must be well sealed.

In winter, the weather in the north is cold and windy, so the sealing of the house is very important. Generally, the method of nailing plastic sheeting can be adopted, and conditional straw curtains can also be used to seal the window. The door must be covered with a cotton curtain to prevent people from going in and out frequently to take away the heat. If several houses are one, several houses should be opened, the doors that are not in use should be closed, and cotton curtains should be used between them. Two doors can be set up if necessary to reduce the direct entry of cold air into the room.

2. Strengthen the work of heating

Heating facilities can use coal stove (general honeycomb coal stove, smoke is small, and easy to manage, should be the first choice), conditional or large heating area can use heating gas for unified heating. When setting up the number of coal stoves or heaters, the temperature of the adult and pupa room should be higher, and the temperature of larvae due to their own friction can be appropriately lower (3-5 degrees). Special attention should be paid to heating at night, otherwise it will be hot during the day, cool bugs will not grow normally at night, and the temperature should be kept above 10 degrees both day and night, otherwise it will not meet the needs of insect growth, on the contrary, it will increase the cost of breeding. Humidity can be solved by boiling water on the stove.

3. Feed should be kept at a certain temperature

The feed and vegetable leaves fed on the same day should be put indoors in advance so that their temperature is close to the indoor temperature, so as to prevent insects from eating overcooled feed and prevent the decrease of insect body temperature caused by disease and low temperature, affecting normal growth. If there are conditions, the feeding proportion of corn flour can be increased appropriately and the heat can be increased.

4. Pay attention to prevent gas poisoning

Bugs also need to breathe, so we must also pay attention to prevent gas poisoning. The method is to open a breathable hole before and after the window of the house, causing air convection, which can effectively prevent gas poisoning, and at the same time seal the stove and install the chimney to prevent the backflow of smoke. When the temperature is high at noon, the door can be opened for short ventilation.

5. Winter transportation

Two links should be paid attention to when transporting bugs in winter: one is that the bugs should be placed in a relatively low temperature environment for a period of time before loading to make them adapt to the transport environment, and the other is to cover the front of the car with canvas to prevent the cold wind from blowing directly to the bugs. At the same time, it should be loaded and left to reduce the exposure time of the bugs in the cold air.

How to choose the species of Tenebrio Molitor?

When selecting insect species for the first time, it is best to buy from a breeding unit authorized by the national science and technology department or the agricultural department. In the future, you can learn to cultivate insect species by yourself and change them every 2 or 3 generations. Note that:

Individual size, 3500 to 4000 pieces per kilogram

The body is strong, the body is full and full, the color is golden, the body surface is shiny, the ventral white part is obvious, and the big larva is more than 2.5 or 3 years long.

Strong vitality, fast crawling, quick response to light, like darkness. When you put the bug in the palm of your hand, you crawl quickly, and you will climb up to feed when you encounter vegetable leaves and fruit peel.

It's nutritious. It is required to raise and manage meticulously from the early age, constantly increase feed, melons and vegetables, and reduce feeding density, so as to produce fat, strong and dynamic varieties.
