Control techniques of common insect pests in Pleurotus ostreatus

The common pests of Pleurotus ostreatus are mushroom flies, mushroom mosquitoes, mites, nematodes, jumpers and slugs. In their egg-laying culture medium, the larvae reproduce in the culture medium, which harms the mycelium and causes the culture material to rot. Adults such as night moths also eat the stalk and mycelium of Pleurotus ostreatus and spread pathogens. In addition, the whole process of cultivation and mushroom production should be prevented. Rats eating mushroom seeds, crawling bed materials or biting mushroom bags are also problems that lead to reduced production.

Preventive measures: pay attention to environmental hygiene, clean inside and outside the mushroom before planting mushrooms, and spray with formalin, dichlorvos or chrysanthemum, or fumigate with fumigant before sowing and inoculation; plastic film and other appliances used in bed planting should be sterilized before use, clean up in time after use, clean up the residue dropped during inoculation, close doors and windows, and install window screens conditionally to reduce the invasion of insects and rats.

Treatment measures: when Penicillium and green mold appear locally on the mushroom bed, you can sprinkle lime or carbendazim powder on the surface of the bacteria, or cover the bacteria with some potassium permanganate solution to inhibit the growth of the bacteria, and remove the sick Pleurotus ostreatus in time when there are insect pests.

Note that during the mushroom period, it is best to collect a batch of mushrooms and spray them when there are no mushrooms, so as to avoid the impact of pesticide residues on human consumption of mushrooms, and to prevent the impact on mushrooms, which is easy to cause deformities.
