How to raise dung beetles artificially

Dung beetle is also called dung beetle, and many people call it dung beetle (g è) beetle, push pill and so on. It belongs to the subfamily Coleoptera. There are about 2300 species of dung beetles in the world, distributed on any continent outside Antarctica. Dung beetles can use moonlight polarization to locate to help feed. It has a certain phototaxis. Insects that drill into cow dung can roll the manure into a ball and push it forward. Mainly feed on animal droppings, there is the title of "natural scavenger", also known as "Moduoji".

Shape feature

The figure is slightly flat oval, with a length of 5mm and 30mm. The body color is mostly glossy black, but also brown. The head is flat, the forelegs are strong, and the male has horns. It is a completely abnormal insect. The body surface is dark, and some have metallic luster. There is a long and curved horn on the top of the male's head. Dung beetles can make use of moonlight polarization to locate to help feed and have certain phototaxis. Its insects are deep-eyed and high-nosed, shaped like Qiang Hu, carrying black armour and shaped like warriors, so they are known as dung beetles and generals.

So how do dung beetles be raised in captivity?

I. breeding facilities

1) the method of insect cage culture on the ground. Outside, a triangular iron frame is used to set up a worm cage with a length of 3m and a width of 2.5m, and the underground is surrounded by stainless steel wire mesh.

Deep 100cm. The upper part is covered with a nylon net with an aperture of 0.5cm. Dig a drainage ditch around the insect cage from the 20~30cm, with a depth of 90cm and a width of 20cm. Leave a door on one side of the worm cage for easy operation and management. At the same time, fresh pig manure should be put in time, and then once every 2 or 3 days.

2) Underground insect cage culture. Five ponds were dug underground, round, 100cm in diameter and deep 80cm. The surroundings and bottoms of the ponds were surrounded by stainless steel nets, exposed 20cm, and then filled with soil. The above ponds were covered with nylon mesh, 20 pairs of insects were planted in each cage, and fresh pig manure was put in at the same time.

3) cement pond culture. Build 5 cement ponds, square length, width and height 100cm, wall thickness 15cm. Fill it with solid soil and add water to the soil according to the appropriate soil water content needed by the cockroach. The soil in the pond is 10cm away from the surface of the pool. The cover is covered with stainless steel wire or nylon mesh, leaving 10cm space between the cover and the soil surface. 20 pairs of adults were put into each pool. All management methods are the same as above. In view of the impervious characteristics of the pool, a cover is added to the cement pool to prevent stagnant water.

4) the breeding method of brick wall farm. When carrying out large-scale aquaculture, in the high dry and flat area with leeward and sunny direction, the enclosure is 130 to 150 square feet.

The brick wall is 140cm high, the foundation of the underground wall is 1m, the brick wall is sealed with cement, and one steel wire hook is installed on the surface for each 30cm.

In order to fix the upper nylon net, the aperture 0.5cm of the net, in order to support the nylon net, there are 3 to 4 cement columns with a height of 180~190cm, and several lead wires are radiated around with the cement column as the fulcrum to hold the nylon net from sinking. Leave a door on one side of the wall at the height of the wall. There is no gap between the door and the wall to prevent adults from escaping. In order to keep the farm dry without stagnant water, a cross-shaped drainage ditch is opened in the farm, there is a dark communication to the outside, and the outlet is blocked with stainless steel mesh. To prevent adults from escaping and other wild animals from getting into the insect body. The density and management method of insect feeding are the same as those of other feeding methods above. However, in the place where fresh pig manure is thrown, a movable shade should be built temporarily to prevent the utilization rate of fresh pig manure from being dried.

2. Feeding and management

1. Choose the species of insect. The breeding insects are the best from May to June, because these adults are overwintering adults and can lay eggs in a month once they are released. The temperature in July is too high, so the species and insects are easy to die in transportation. At the same time, during this period, there is heavy rain or torrential rain, and the feed is easily washed away, which will also cause the death of species and insects (except those with rain shelter). When breeding insects, individuals with large, strong and intact wings and feet are selected and released according to male and female at about 1:1, in order to improve the survival rate and reproduction rate.

2. Feed frequently. After planting insects, feed them in time. At first, feed every day, and then replenish it at any time depending on the feeding situation. Once every 2 or 3 days. In the choice of food, although human manure is better than pig manure and pig manure is better than cow manure, according to the source and habit, pig manure is the most convenient feed. When putting it, we should pay attention to choosing fresh feces, moldy or sun-dried ones.

3. Pay attention to the enemy. It was found that earthworms and mole crickets were the main enemies in breeding. The soil chamber is often drilled or drilled through, resulting in the destruction of mud balls and the death of larvae or pupae. In order to avoid its harm, attention should be paid to reducing soil moisture and selecting sandy loam with high dry and low fertilizer content.
