Shiitake mushroom planting gall mosquito pest is harmful, how to prevent and control it?

After dismantling the wooden bed frame of the mushroom room, soak it in water for 10 days, wash it and dry it, rinse the mushroom room with bleaching powder, and scrape 3 cm on the soil floor; Doors and windows are open day and night to keep them dry and cold. Before the production of autumn mushrooms, the bed frame is set up, and the empty room is fumigated with dichlorvos once, sprayed with bleaching powder once, and sprayed with lime slurry water again. Cement bed frame, first brush with cement mortar, then brush lime slurry water.

Edible fungus mites are mainly brought into the cultivation site in warehouses, feed rooms, chicken coops and coarse bran, cottonseed cakes, rapeseed cakes, etc., or through insects. Mushroom mite infestation generally occurs when the culture material enters the house and is sown to the first stage.

In the first and second tide mushroom stage, the mycelium often begins to eat the mycelium when it occurs to 2 3 cm in the vertical and horizontal direction of the material after sowing, and the damaged hyphae then no longer elongate, and the mycelium of the whole mushroom room is destroyed in serious cases. Pry open the culture material layer of the infested mushroom, and it is yellowish-black. If the oyster mushroom is infested by mites during the germination period, the white fungus will turn black and emit unpleasant mite damage, and the white fungus will turn black and emit an unpleasant musty smell.

Stabbing Hazards:The surface of the mushroom body is shrunken, not smooth, loses its original luster, is drier, and the water content is lower than that of normal mushrooms. When the stinging is severe, the surface of the mushroom appears soot powder, and finally the mushroom withered.

Canola cake booby-trap:The sautéed rapeseed cake has a strong oily flavor. Spread a number of pieces of gauze on the material surface, sprinkle a layer of freshly fried rapeseed cake powder on it, and the mites will gather on the gauze.

Then soak the gauze in boiling water or concentrated lime water to kill it, and then wash it. Repeatedly, the effect of mite control can reach more than 90%. Sweet and sour booby-trap:

Take 1 part acetic acid, 1 part water, and some sugar, mix well and drop into dichlorvos to form sweet and sour liquid. Put gauze or cotton soaked in the chemical solution on the surface of the material, and when the mites gather on it, remove the scalding pests. Repeat until there are no mites.

Stone sulfur mixture:Lime, sulfur, and water 1:1:

10. Mix and boil, then dilute to 5 Baumé spray for empty room disinfection. If mixed with a 500x dilution of dicocidal sulfone, the acaricidal effect can be improved. Examination of the culture:

Put the culture bottle in the sun for 1 hour, the mites should crawl on the shoulder of the bottle and the tampon, and then carefully check with a magnifying glass for harmless mites.

The method of fumigation with aluminum phosphide can effectively kill insect pests without damaging the mycelium. Other agents such as phosphine spray and aveinbacterium spray can also kill insect pests.

Control by spraying pesticides. Some pesticides can kill the galls.

Pests can be removed by salicylic acid, which is generally 5% to 15%.

You can use regular fertilization, but you can also apply a little pesticide on the shiitake mushrooms, which of course need to be non-toxic and harmless.

Special chemical fertilizers should be used, as only then will crops be better protected from invasion by this pest.

Eye mosquitoes, jumping worms, nematodes, slugs, termites and other insect pests, but there are relevant methods for these insect pests.

1. Ophthalmic mosquitoes, the larvae of the insect feed on cultures, and the older larvae feed on the fruiting bodies of shiitake mushrooms and other fungi.

2. Jumping insects, also known as soot insects, harm hyphae and fruiting bodies.

3. Nematodes, the surface or all harmful culture materials will become wet, black, viscous, mycelium will atrophy or disappear, and small mushrooms will die. The surface of the dead mushroom is sticky and smelly. In humid, sultry, and unventilated conditions, nematodes can easily occur.

Nematodes, the surface or all of the culture material harmed by nematodes will become wet, black, sticky, mycelium will shrink or disappear, and young mushrooms will die. The surface of the dead young mushrooms is sticky and has a fishy smell. Under humid, sultry, and unventilated conditions, nematode damage is prone to occur.

Shiitake mushroom-eating gall mosquito, also known as mushroom-loving gall mosquito, mushroom gall mosquito, is easy to lead to the decline of mushroom quality and yield, and the heavy one is not harvested. Therefore, farmers must take timely measures to prevent and control it. So, how should farmers deal with mushroom-eating gall mosquitoes?

Symptoms: larvae are used as pests for all kinds of edible fungi. The larvae in the germination stage are harmful in the material, and most of them are transferred to the covering soil layer after covering the soil to damage the villous hyphae and fruiting body, and the mushroom buds are yellow, shriveled and died.

After the fruiting body is unearthed, it can reach the mushroom root when the number of worms is small, and it can spread to the whole mushroom body when the insect mouth base is dense, and the mushroom body can often be seen to be orange-red or light red due to larvae burrowing. When there are few mushrooms and many larvae, the covering soil is a layer of red powdery substance, and the larvae burrow into the shallow skin layer of the mushroom meat when the temperature is low. The murdered fruiting body quickly decays.

The larvae prefer humidity and move freely in wet places and can survive for many days in water, while they have difficulty moving in dry conditions, relying on the strength of their bodies to curl up and spread, or many larvae gather together to form a red ball to protect their survival. When the environment is suitable, the sphere disintegrates and the surviving larvae continue to reproduce.

Occurrence rule: When the peak of adult featuration is 12 13, after eclosion, it can fight before mating and laying eggs, and the eggs are laid between the soil cracks of the mushroom bed. Before hatching, the eggs change from white to light brown, the temperature is 18, the relative humidity is 70-80%, and the egg period is about 4 days.

At room temperature 18 20 and relative humidity 68% 75%, after 10 to 16 days, the mature larvae enter the surface layer of the material or the surface layer of the soil block to pupate. The larvae overwinter dormant in the culture medium. Before the pupation, the compound eyes and wing buds of the pupa turn black, the pupa body continues to swing left and right, leaving the soil room, and then 2 3 hours before the beginning of feathering, the room temperature is 18 20, the relative humidity is 68% 75%, the pupal stage is 6 7 days.

Control measures: 1) Cultivation. The doors and windows and ventilation holes of the mushroom room are equipped with screen doors and screens to prevent adults from flying into the mushroom room and then cultivating materials or primordium to lay eggs and reproduce, so as to reduce the source of insects.

Manual capture. The Chinese mosquito has a habit of living in groups, because the adults and larvae are relatively large, so attention should be paid to catching the larvae when cleaning the material surface after mushroom picking. Adults are phototaxis and often fly to the window of the mushroom room or near the light to rest or mate, and can be beaten with a fly swatter.

2) Pharmacy. When the occurrence is severe, spraying 1000 times the liquid of trichlorfon, the lethality rate of the larvae is 100%, and the lethality rate of the pupal is 90%, and the lethality rate of the 500 times trichlorfon liquid to the larvae and pupae is 100%.
