First, the preliminary preparation of breeding Eupolyphaga sinensis
The Eupolyphaga Seu Steleophaga breeding house should be selected in a higher place to prevent water accumulation.
The breeding house can be a waste and idle house. The light in the house should be as dark as possible, and the front and rear windows should be opened with screens, and the door should be double-decked.
The size of the breeding pond depends on the amount of breeding, and the bottom of the pond is treated with cement to prevent escape.
Eupolyphaga sinensis can also be raised in boxes and pots, and the boxes and pots can be set up layer by layer for three-dimensional culture, which can make full use of space and improve yield.
To improve the survival rate of Eupolyphaga Seu Steleophaga, firstly, we should choose loose and fertile garden soil or sandy loam rich in humus, add appropriate amount of chicken manure, pig manure or plant ash into it, and expose it to the sun to make it.
The humidity of the soil is generally 20%-25%, so it is advisable to hold it in hand and let it go.
Second, the management of Eupolyphaga sinensis larvae
The suitable temperature for larvae to hatch is between 25-30℃, and the humidity of feeding soil should be kept at about 40% during hatching. After one month, larvae can break their shells.
Once the seedlings are hatched, they should be raised separately from the mother immediately to avoid being eaten by the mother.
When the larvae are young, they are mainly fed with intensive feeding, and they are fed with foods with rich nutrition and easy absorption, such as egg yolk and meat foam.
Usually, we should also pay attention to the heat preservation and moisturizing of larvae.
Third, the main points of daily feeding of Eupolyphaga sinensis
Eupolyphaga sinensis is an omnivore, and it is not picky about the types of food. The feed is mainly concentrated feed (wheat bran, rice bran, etc.), supplemented by green feed (vegetables, peels, melons, etc.).
Animal feed, such as various fish, meat, shrimp, internal organs of livestock and poultry, and by-products after processing of dairy products, is also a favorite feed for Eupolyphaga sinensis.
If the growth is slow by feeding grass and other feeds alone, the complete feed can be 72% wheat bran, 20% corn flour, 5% bean cake and 3% animal feed (cooked feed).
The feeding amount must be sufficient, otherwise there will be mutual cannibalism.
Fourth, the temperature and humidity management of Eupolyphaga Seu Steleophaga has strict requirements on temperature and humidity. The suitable growth temperature is 25-30 degrees, and it will hibernate below 8 degrees, and it will start to eat at 10 degrees. If it is below 0 degrees, it will freeze to death, and if it is above 38 degrees, it will die of heatstroke.
The weather is hot in summer, and under the condition of feeding semi-dry and wet materials, several small pots filled with water can be placed in the breeding pond for them to drink.
Keep dry in winter, feed semi-dry and wet materials, and keep warm with straw at low temperature.
5. Pest control of Eupolyphaga Seu Steleophaga 1. Disease control of Eupolyphaga Seu Steleophaga mainly includes diseases such as pot-bellied disease and fungal infection.
The prevention and treatment of pot-bellied disease is to adjust the dry humidity of feed and feeding soil, and the moisture should not exceed10%;
The prevention and treatment of fungal infection is mainly to replace the feeding soil, and disinfect it in time, and then grind it with 0.25 g tetracycline and feed it with mixed materials to cure it.
2. Pest control The pests of Eupolyphaga Seu Steleophaga include mites, ants, rats, cats, snakes, etc. When breeding, we should pay attention to the defense and blockade of the farm, and don't let the pests have an opportunity.
For tiny pests such as ants and mites, tung oil and sticky substances can be coated on the wall of the pond, and mites can be controlled with chemicals.
