Control of diseases of Tenebrio Molitor in culture

The main results are as follows: (1) mite damage is easy to occur from July to September, and mite eggs are the main cause of mite damage. Therefore, the bait of Tenebrio Molitor should be sealed and stored in this season, and rice bran, wheat bran, soil miscellaneous grain noodles and coarse corn flour had better be exposed to the sun and then fed. Another point can not be ignored, mixed in the pericarp, vegetables, wild vegetables should not be too wet, because the summer temperature is too high easy to lead to corruption. It is also necessary to remove insect dung and residual food in time, and keep the feeding box clean and dry. If mite is found in the feed, it can be moved to the sun for 5 minutes (the feed is spread flat) and the mites can be killed. 1000 times of dicofol can also be used to spray feeding places, such as wall corners, feeding boxes, feeding utensils, or directly sprayed on feed, and the acaricidal effect can reach more than 80% 95%. However, the best way is to raise insects scientifically, which is the effective way to put an end to the occurrence of mites.

(2) the symptom of this disease is that the head and tail of the disease is dry, and the serious ones develop to dry up and die as a whole. The main causes of the disease are high temperature, dry air and too little green fodder in the feed. In the hot summer, the feeding box should be placed in a cooler and ventilated place, various vitamins and green fodder should be replenished in time, and water should be sprinkled on the ground to cool down to prevent the occurrence of the disease.

(3) the soft rot disease mostly occurs in the plum rain season, the movement of the disease and insect is slow, the appetite is decreased, the litter is less, and the serious insect becomes black, soft, rotten and dies. The main cause is that the damp air in the breeding place is difficult to screen and the excessive force causes the insect body injury. After discovering this situation, we should immediately reduce the amount of vegetables, clean up the feces of diseases and insect pests, open the doors and windows to vent the tide, adjust the appropriate temperature, take out the diseases and insects that have softened and blackened in time, and feed them with 0.25 grams of chloramphenicol or oxytetracycline mixed with bean flour or corn flour 250 grams per box, and then change to wheat bran mixed with green material when the situation improves.

(4) the natural enemies of yellow powder insects are rats, ants, cockroaches, toads, chickens, ducks, geese and dogs, which should be paid special attention and precautions when raising temporarily in the courtyard.
