Cockroach culture technology

Periplaneta Americana, a cockroach with large size, wide food range and strong reproductive ability, is a good breed in captivity. There are two forms of culture: 1, mixed culture with Tu Yuan, exclusive culture of cockroaches and mixed culture of Tu Yuan, and the production of soil raised by Tu Yuan. In the practical operation of our field, it is found that there is not much conflict between cockroach and Tuyuan mixed culture, and even produce complementary advantages. Cockroaches do not enter the ground, and special animal medicine has high efficiency and good market. during the day, it only drills into the cracks in the walls of the pit house and comes out to look for food at night. While Tuyuan goes to the ground during the day, he also comes out in the evening to hunt for food. in the process of raising Tuyuan, there will be a lot of feed that can not be eaten on the same day, which is excellent food for cockroaches. And the light, temperature and humidity in the Tuyuan breeding room are also extremely suitable for cockroaches. In our practice, we found that when the source of feed is insufficient, adult cockroaches also prey on soil larvae. The solution is: ① controls that there is a certain amount of light in the feeding room during the day, so that cockroaches can not come out to look for food. When raising food, ② also put some feed on the stalls of Tuyuan pit, so that cockroaches will not be hungry and prey on Tuyuan larvae.

Cockroach nursery. The requirement of cockroach breeding room is high, when setting up cockroach breeding room, you need to pay attention to the sealing degree of the house, preferably a flat-roofed house, the tightness of the house should be fully checked, a small gap will cause the small cockroach to jump. A partition wall is built around the house, and the upper and lower dimensions are determined according to the size of the inner pit room. After the partition wall is finished, what are the methods of breeding wild cockroaches with cement? stop work for 2 days or paste the wall with a 3cm foam plate to keep warm, hang a plastic film on the inner wall of the foam plate and require it to be hung all around. Then check the cracks in the cement wall and make up the cracks. The design of the pit pool is set according to the size of the house, leaving a walkway of 1 meter, with a height of 40 centimeters on each floor, pre-poured with reinforced concrete and cast into a trough-shaped pit with a small groove extending down 25 centimeters and a gap of 10 centimeters. In order to facilitate the operation, the amount of steel bar in pouring the pit should not be too small to prevent the trough-shaped pit from breaking when laying the pit. Cockroach trough-shaped potholes only need to be placed layer by layer, and the total height of the pit room should be less than 2.6 meters. When the code is placed on the top floor, it is sealed with concrete on the top floor to prevent the cockroaches from escaping. Heat preservation materials such as forage and foam are placed on the top. The doors and windows of the cockroach pit house should not be made of wood. Wooden doors and windows will be bitten off by cockroaches and are made of aluminum alloy or plastic steel. When making, we should also pay attention to the tightness, seal and prevent jumping with stainless steel screen on the outside of the doors and windows, and block the strong light outside with black cloth curtains. At each end of the aisle of the breeding pond, there is a smoke fontanelle-shaped vent with a pipe diameter of 8-10 cm. The ventilation window is separated by window screen, and the heating facilities in the cockroach pit room can be set flexibly. Electric furnace, honeycomb coal stove and wood chip furnace can be used, but the waste gas should be discharged outdoors to ensure the success of breeding and the safety of breeders.

I. Culture form

The cockroach species cultivated in our farm is Periplaneta Americana, which belongs to the genus Periplaneta of the cockroach family. This cockroach has large size, wide food range and strong reproductive ability, so it is a good artificial breeding variety. There are two forms of culture: 1, mixed culture with Tuyuan, exclusive culture of cockroaches and mixed culture with Tuyuan. In the practical operation of our field, it is found that there is not much conflict between cockroach and soil element mixed culture, and even produce complementary advantages. Cockroaches do not go to the ground. During the day, they only drill into the cracks in the walls of the pit house and come out at night to look for food. While Tuyuan goes to the ground during the day, he also comes out in the evening to hunt for food. in the process of raising Tuyuan, there will be a lot of feed that can not be eaten on the same day, which is excellent food for cockroaches. And the light, temperature and humidity in the Tuyuan breeding room are also extremely suitable for cockroaches.

The upper and lower dimensions are determined according to the size of the inner pit room. After the partition wall is finished, wipe it with cement and stop work for 2 days, then check the cracks on the cement wall and make up the cracks. The design of the pit pool is set according to the size of the house, leaving a walkway of 1 meter, with a height of 40 centimeters on each floor, pre-poured with reinforced concrete and cast into a trough-shaped pit with a small groove extending down 25 centimeters and a gap of 10 centimeters.

Wooden doors and windows will be eaten by cockroaches and are made of aluminum alloy or plastic steel.

The heating facilities in the cockroach pit room can be set flexibly. Electric furnace, honeycomb coal stove and wood chip furnace can be used, but the waste gas should be discharged outdoors to ensure the success of breeding and the safety of breeders.

2. Feeding and management

Cockroaches eat a wide range of food. As mentioned above, even wooden doors and windows will bite, generally rotten vegetables, melons and fruits, newspapers, abandoned cakes, grain and so on, so the feeding cost is quite low, artificial feeding almost no feed input cost. Cockroaches often come out at 18:00 at night, peaking at 21mur23 and hiding the next morning, so they only need to be fed once a day at 17-18:00 and the feed is placed on the platform between each floor. The amount of feed is determined according to the amount of food they eat. Use a duster to sweep away the remaining feed and its faeces every 5 days. Can spray water on the feeding platform to humidify or autocratic sink for cockroaches to drink.

The egg blocks laid by cockroaches are brown, about 1 cm long and 0.5 cm wide. A female cockroach can lay 30 mi 60 eggs, as many as 90, and each egg contains 14 mi 16 larvae. The egg mass is laid on the wall or on the grass stem. When we collect cockroach eggs, we only need to put grass handles on the breeding platform, and nearly half of the cockroaches will lay their eggs on the grass handles, which can be collected by shaking the grass every few days.

When the temperature is about 25 ℃, the hatching period of the egg is 20 Mel for 30 days, and the larva becomes an adult after molting several times for 5 months. The larvae have no wings and have long wings in the mature stage, and the males mature later than the females. The last molting of the female is about half a month and begins to lay eggs. American cockroaches have the habit of asexual reproduction. If there is no male, the female can lay unfertilized eggs, and the unfertilized eggs are all female after hatching and can reproduce continuously for 3 generations. Our artificial breeding of cockroaches can keep the pit house at 25 ℃-30 ℃ all the year round, and this condition can enable cockroaches to complete a generation in 6 months. The 100-square-meter pond can produce 1600ml 2000 kg of fresh cockroaches per year. The economic benefit is quite high, in the feeding process, the feed must avoid pesticide pollution, pesticides are of course prohibited.
