Common pests of Lentinus edodes and their control

1. Mites are commonly known as fungus lice, which are divided into acaroid mites and mite mites. The mite body is small and not easy to be seen by the naked eye, and they are mostly concentrated on the surface of the culture material; the mites are large, white, not agglomerated, and are powdery when they are in large quantities. The mycelium of Lentinus edodes with mite pests is bitten and can be eaten up in severe cases.

If mites occur in the bacteria, they can be fumigated with 50% dichlorvos in cotton plugs. Mites can be sprayed with 0.5% dichlorvos or 2000 times of pyrethroid. Mites occur during mushroom emergence, which can be sprayed with pyrethroid, but the mushrooms can not be picked until 3 days after spraying.

2. The young larvae of eye mosquitoes feed in the culture medium, while the older larvae eat the fruiting bodies of Lentinus edodes and other fungi.

Prevention and control methods: mushroom houses, mushroom farms and the surrounding environment should be kept clean. Before cultivation, mushroom houses and mushroom farms should be sprayed with 40% dichlorvos 1000 / 1500 times. During mushroom emergence, eye mosquitoes can be sprayed with 40% dichlorvos 1000 / 1500x, or 25% pyrethroid 2000 times.

3. The larvae of gall midge are mainly harmful to mycelium and fruiting body, and the control method is the same as that of eye mosquito.

4. Jumping insects are also known as spring tails, ash insects and so on. Control methods: 40% dichlorvos 500 times solution should be sprayed in indoor and outdoor cultivation and mushroom farms. If the harm of jumping insects occurs during the infection period, dichlorvos and honey can be used to trap and kill, that is, 40% dichlorvos 500 times liquid is sprayed on the paper, then drop a few drops of honey, and spread the medicine paper on the culture surface to trap and kill. The harm of jumping insects occurs during mushroom emergence, which can be killed with 0.1% ivy essence or pyrethrum.

5. The surface layer of the culture material damaged by nematodes will become wet, black, sticky, the hyphae will shrink or disappear, and the young mushrooms will die. The dead young mushroom has a sticky surface and a fishy smell. Nematode damage is easy to occur under humid, muggy and unventilated conditions. Prevention and control method: can be sprayed with 2% formaldehyde solution. When nematode damage occurs on local culture materials, some of the damaged nutrients can be dug up and sprayed with formaldehyde.

6. Slug, also known as slug, is a kind of mollusk that lurks in dark and humid places during the day and comes out at night. It bites on the fruiting bodies of mushrooms and other edible fungi. At 9-10:00 at night, it can be caught manually when the slug comes out. Or spray 1% potassium permanganate solution or 5% salt solution on its swimming place and route.

7. Termites mainly harm mushroom wood. Prevention and control methods: use 80% arsenous acid, 15% salicylic acid, 5% ferric chloride to form poison, spray ant road and ant nest, spray 6Mel 16ml per nest; or use 50% liter mercury, 35% arsenite acid, 10% salicylic acid, 5% ferric chloride to prepare termite powder, spray ant nest, as long as some termites are dipped in medicine, the whole nest can be destroyed.
