What does Auricularia auricula harm long head mite look like? What are the main points of prevention and control?

Auricularia auricula is a widely cultivated fungus, and it is easy to invade diseases and insect pests because of improper management in the production process. Among them, Auricularia auricula long head mite is a very harmful pest, which will feed on the hyphae and fruiting bodies of many varieties of edible fungi, and even different types of miscellaneous bacteria, once it occurs, it will cause great economic losses to growers. What does the long-headed mite look like? What are the main points of prevention and control?

First, what does the fungus harm the long-headed mite look like?

The non-pregnant female mites are flat and pearl-white in color, and when they gather together they are as dense as pearl powder. If it is a pregnant female mite, it is more round and longer, which is several times the size of the non-pregnant mite.

Generally speaking, if Auricularia auricula harms long-headed mites, there are only two periods, namely, egg and adult mites, and there is no infancy. Mite eggs directly develop into adult mites in the mother, and then drill out from the mother, so it is the birth of eggs.

Female adult mites look for hyphae or fruiting bodies to eat as soon as they come out of the mother. In general, within the time of the day, most of the female mites will feed in one place, and the latter part will slowly become larger, which is called abdominal distension. The specific body size is determined by the amount of food and the space for growth.

When the ear slices of Auricularia auricula are picked and fed to the mites, most of the swollen abdomen is round, and the shape is usually long tube if it is above the fruiting body of Auricularia auricula in the original bottle. So most of the swollen bellies that grow on cultures with large space and individuals are not very crowded are spherical, otherwise they are in the shape of a long tube. The size of the dilated abdomen ranges from 2 to 4mm, and the longest can reach 7mm, which can be observed with the naked eye. If the temperature is at 27 degrees Celsius, it will take only eight days to complete the reproduction of one generation.

2. Harmful characteristics of long head mite caused by Auricularia auricula

Long-headed mites like to eat edible fungi such as Auricularia auricula, especially in the primordium, and gnawing is the most serious. In the auricularia auricula fruit body can be seen in the shape of a long tube-shaped abdominal swelling, the so-called harmful long-headed mite. It can also enter the bottle of bacteria through cotton plugs, and then bring in some miscellaneous bacteria, infect bacteria, and naturally reduce production.

III. Control methods of long-headed mites caused by Auricularia auricula

1. Do a good job in the sanitary work of the strain production site, especially to reduce the pollution sources of miscellaneous bacteria, and the abandoned bottles of miscellaneous bacteria should be disposed of immediately to avoid insect sources.

2. In the production of bacteria, the cotton plug should be stuffed into the strain bottle, which can effectively reduce the crawling of harmful mites.

3. The operation of introduction must be strict to avoid the spread of harmful mites. At ordinary times, we should also do a good job in regular inspection of the breeding places of bacteria.
