1. The crickets are commonly known as bacillary dysentery, and they are divided into two types, ie white pupa and pupa. Puqi body is small, not easy to see with the naked eye, they are mostly concentrated on the surface of the culture material; powder body is larger, white shiny, not a mass, a large amount of powder. Mushroom fungus of fleas occurs, and the hyphae are bitten. In severe cases, the hyphae can be eaten. Aphids occur in strains and can be smeared and killed by 50% of the dichlorvos. During the fungus, aphids appeared, which could be sprayed with 0.5% dichlorvos, or sprayed with 25% chrysotide 2000 times. There are locusts during fruiting, which can be sprayed with chloralloate, but it is not until 3 days after spraying. 2. Small instar larvae of mosquitoes feed on culture materials, while older larvae eat fruiting bodies of mushrooms and Other fungi. Control methods: mushroom house, mushroom farm and the surrounding environment should be kept clean and hygienic. Before planting, mushroom house and mushroom field should be sprayed with insecticide, and 40% of dichlorvos can be sprayed with 1000-1500 times liquid. Occurrence of eye mosquitoes during fruiting can be sprayed with 40% dichlorvos 1000-1500 times, and can also be controlled with 25% chrysanthemum ester 2000 times liquid spray. 3. The larvae of the gall midge mainly harm the mycelium and its fruit bodies, and the prevention and control methods are the same as those for controlling the mosquitoes of the eye. 4. Collembola is also known as collembola, tobacco worm and so on. Control methods: Indoor and outdoor cultivation and mushroom farm use 40% of dichlorvos 500 times spray. During the period of germination, the insects could be killed by pests, and they could be trapped and killed with dichlorvos and honey. That is, they sprayed 40% of dichlorvos 500 times on paper and then dropped a few drops of honey to disperse and spread the medicinal paper on the surface of the culture material. During the fruiting period, the insect is harmed by the insects, and 0.1% of rattan extract or pyrethrum can be killed. 5, nematodes infected by nematodes damage the surface or all of the material will become wet, black, sticky, hyphae shrink or disappear, young mushrooms died. Dead mushroom has a sticky surface with stench. In the humid, hot and unventilated conditions, it is prone to harm by nematodes. Control methods: Use 2% formaldehyde solution to spray to kill. When nematode damage occurs in local culture materials, some of the damaged nutrients may be excavated and sprayed with formaldehyde. 6. Aphid also known as slugs. It is a kind of mollusc. It lurks in the dark and humid place during the day and comes out at night. It eats the fruiting bodies of mushrooms and other edible mushrooms. It can be used during the night when it is 9-10. Manual capture, or spraying 1% potassium permanganate solution or 5% salt solution in its swimming place and route. 7, termites mainly harm mushroom wood. Control methods: Use 80% arsenious acid, 15% salicylic acid, 5% ferric chloride, dubbed poison, spray ant road, ant nest, spraying 6-16 ml per nest; or use 50% litre Mercury, 35% arsenious acid, 10% salicylic acid, and 5% ferric chloride were formulated as termite powder and sprayed on the ant nest as long as part of the termites could be destroyed by the whole nest.
