Eggs, larvae, cockroaches, and adults of different stages of development are kept separately to facilitate feeding according to different requirements. It is also possible to prevent larvae from eating cockroaches. Adults easily eat eggs when they eat; basically the same age of the larvae. They should be kept together for feeding, marketing, and rating. If the larvae need to be replenished at high velocities, mature larvae are not needed. Adult worms that have just emerged are tender and have poor resistance and cannot eat more green feed.
Second, note that monoculture:
When the larvae grow to the fifth instar, they will begin to become warty. The larvae should be picked out of the terrarium in a timely manner and placed in a separate place. Because you do not eat food or move, if you put together with the larvae will be bitten or killed by larvae.
Third, pay attention to the density:
The thickness of the larvae in the terrarium should not exceed 2 to 3 cm in order to prevent fever from causing death. The pods should be placed in a ventilated, dry and warm environment. They should not be closed and overly moist, so that the pupa rots yellow to black. In hot summer season, the moltings are easy to dry and should be properly turned and sprayed with a small amount of water droplets to keep the skin moist. Both larvae and adults have habits of killing each other. Therefore, the stocking density should not be too large.
Fourth, pay attention to cleaning:
The terrarium should be kept clean and the dead fleas or adults must be removed in time to remove the fleas and feces from the larvae. The method of clean-up is: Don't put feed into the terrarium within the first three or four days of preparation for clean-up. Try to make it eat as much as possible. Then use a sieve to separate insects of different ages and isolate insects. Need to use several specifications of the sieve, the screen type can be 100 mesh screen (for larvae over 10 years of age), the old mature larvae can use ordinary screens.
Fifth, pay attention to management:
With the changes in temperature in different seasons, management methods are also different. If the weather is high, the larvae grow vigorously and there must be sufficient water. Therefore, more green feed with more water content must be fed, and ventilation and cooling should be taken into consideration. In winter, it is necessary to reduce feed for green feed and keep it cold.
1, pay attention to 螨 categories:
Anthrax is very harmful to Tenebrio molitor, which results in thin body, slow growth, low egg hatching rate, and reduced fertility. It usually occurs in July-September, when the temperature is too high, the temperature of the feed is large, and there is a time when it is in the feed. Prevention methods: prevent feed from licking, and conditional can sterilize bran and bran in water for 20 minutes. Usually keep indoor air circulation and reduce humidity. Especially when the humidity is too high on summer rainy days, try not to throw or cast too much wet green material. When you find the quail, take the feed to the sun for 10 minutes in time. At the same time, ants and mice are the enemies of Tenebrio, and they should always be wiped out.
2, pay attention to disease prevention:
Blight: After the disease, the head and tail of the mealworms dry up, and finally the body withered and died.
Control methods: In the dry and hot season, timely put green materials or sprinkle water on the ground to cool down.
Soft rot: The insects and insects move slowly, the excrement is thin, and the diseased bodies become black and soft and eventually die. The disease mostly occurred during the rainy season, with damp indoor air, over-wet feed, and excessive stocking density or insect damage.
Control methods: The soft parasite was found out in time, the residual food was removed, green feed was stopped, and the indoor humidity was adjusted. 0.25 g of chloramphenicol or chlortetracycline mixed with 250 g of wheat bran were fed.
