Edible fungus is a common kind of vegetables in daily life, which is delicious and has high nutritional value, and is deeply loved by people. In the process of planting edible fungi, the emergence of insect pests has seriously affected the normal growth of edible fungi. This paper will introduce the preventive measures of edible mushroom pests in winter.

In winter, insect pests in the production of edible fungi are still a major threat, even worse than in summer. Such as mushroom mosquitoes, mushroom flies, jumping insects and so on, seemingly insignificant pests can cause irreparable losses to production in a very short time. In particular, the pests such as mole cricket, cricket, horse land, snail and so on are larger and more harmful. In order to effectively control insect pests, we must adhere to the principle of combination of prevention and control. The specific methods can be summed up as follows:

Physical prevention 1. The mushroom shed should be built away from villages, stable toilets, garbage dumps, dung piles and other places, so that the mushroom environment is far away from the source of insects. two。 Raw and auxiliary materials are exposed to strong sunlight to avoid carrying eggs or live insects. 3. If there are live worms or eggs in the raw materials, do not sow seeds with raw materials directly, at least use them after fermentation treatment, and adopt clinker cultivation or seed production. 4. Strictly check whether the bacteria are infected with worms, and carefully check the purchased strains before transfer to prevent the phenomenon of worm-carrying inoculation. 5. The vents of the mushroom shed and the entrance and exit of the mushroom shed are encapsulated with anti-insect nets to prevent adults from flying in. 6. Spread lime barriers at vents and entrances and exits to prevent reptiles from entering.

Prevention 1. Phoxim is added when mixing, the dosage is generally about 100ml per 1000 kg of dry material, and can be added with the mixture during raw material cultivation, and the time for fermentation material cultivation is added before turning the heap. After high temperature and stuffy heap, the insecticidal effect is very ideal. two。 Within a certain distance outside the shed, efficient insecticides such as trichlorfon can be used to kill insects and cut off the source of pests after cleaning up the waste. 3. Outside the shed and the vents, entrances and exits of the shed, cypermethrin was sprayed with high efficiency and low residue to prevent reptiles from entering the shed. 4. Insecticides such as cypermethrin can be sprayed in the mushroom shed, avermectin is used to kill mites, and efficient paracetamol can be used to ward off mushroom mosquitoes and mushroom flies under certain conditions. the mechanism is: the use of mushroom mosquitoes, mushroom fly adults do not like the smell to ward off, adults do not dare to enter the shed, let alone feed to lay eggs, adults are repelled, the formation of harmful larvae will have no opportunity to take advantage of. The smell can make mushroom mosquitoes, mushroom flies to avoid, even if occasionally into the shed insects, but also because of the unpleasant smell and quickly escape, unable to form harm.

When there are live insects or eggs in the insecticidal bacteria, the bacteria can be packed into a large plastic bag (wide double-layer greenhouse film, which can be made at one end), put into aluminum phosphide according to the dosage of 4 pieces per cubic meter of space, and the bag can be unpacked in about 6 hours.

During the germicidal period, if insect pests occur inadvertently, you can sprinkle water on the ground, cover the plastic film after the bacterial bag is concentrated (pay attention to the temperature to prevent burning bacteria), and put aluminum phosphide under the film, the dosage is the same as above, but you should pay attention to putting the uniform and airtight plastic film. After removing the film for about 6 hours, it can be managed normally.

If pests are found during mushroom emergence, if they are not strictly prevented from entering the net, pyrethroids can be sprayed on adults, and adults of mushroom and mosquitoes are extremely drug-intolerant, according to the concentration of vegetables; if larvae have been found, aluminum phosphide can be used to kill the fruit body, but the fruiting body should be harvested. For young buds, drugs can be used with buds, and the general initial pests can be killed in 4-6 hours.
