Fast-growing thin-mouth mite of edible fungi

Fast-growing acaroid mite (Histiostomaferoniarum) belongs to the genus Tetranychidae. This mite is harmful to mites all over the world, and it is possible to exist and occur in any environment suitable for the growth of edible fungi.

The main results are as follows: (1) the fast-growing mite can infect the mushroom strain bottle, reduce the finished product rate, invade the mushroom bed and affect the yield, so it is one of the harmful mites of cultivated mushrooms. When the humidity of the mushroom bed is too low or there is a lack of food, a large number of reddish-brown active dormant bodies are produced, which gather on the surface or fruiting body of the mushroom bed and spread by breeze or adsorption on insects and other animals. The mite feeds on the residual mushroom spoilage or humus in the culture material, and once the mushroom bed occurs, it will accelerate the decay of the mushroom body, thus increasing the humidity of the bed and worsening the ecological environment of edible fungi, therefore, the occurrence of fast-growing thin-mouth mites indicates that the damaged edible fungi will have a poor harvest or no harvest.

(2) the occurrence regularity is on the fruiting bodies such as rotten mushrooms, Lentinus edodes and Pleurotus ostreatus or in the wet medium, fast-growing mite mites such as juvenile mites, nymph mites and adult mites are often found. When the fruiting body is dehydrated or the medium is dry, dormant bodies appear. The mite likes to be wet and afraid of dry, and often occurs in wet edible mushroom bed and decaying organic matter, especially on the mushroom body infiltrated with suspension, and crawls slowly to feed and reproduce on its surface. When the conditions are not suitable, a large number of dormant bodies will gather on the surface of the culture material. The dormant body holds the ground on feet 3 and 4, and raises feet 1 and 2 so that they can be attached to it and spread through moving objects. Generally speaking, the mushroom beds with poor growth of edible fungi and hyphae decline in the later stage are more common.

(3) the control method ① can cultivate healthy bacteria, improve the rate of finished products, and make the hyphae strong and strong. ② pays attention to environmental hygiene and does not pile up sundries and wastes around the mushroom house to avoid miscellaneous bacteria pollution and reduce the breeding ground of harmful mites. The mushroom house is not built near the grain warehouse. ③ strict disinfection: before sowing, the mushroom room is thoroughly cleaned and fumigated with chemicals; the culture material is fermented or sprayed with pesticides to eliminate harmful mites.
