Control measures of Poria cocos rodent damage

Rodent damage is a serious global problem, which is common in the cultivation of edible fungi such as Poria cocos, Pleurotus ostreatus, mushrooms, Lentinus edodes and Flammulina velutipes, and is one of the outstanding problems in the cultivation of edible fungi.

Damage characteristics in the strain production, the bottled bacteria mainly bite the cotton plug, resulting in the cotton plug loose or even taken out, resulting in the culture material to be contaminated with miscellaneous bacteria. The bacteria in the plastic bag will bite through the plastic bag. Holes can be made in the culture material to destroy the culture material. In the middle and later stage, it directly feeds on the fruiting body, which affects the formation of the fruiting body. After the differentiated stalk and cap are gnawed, there are obvious missing or sunken spots, so that the product loses its commercial value. This pest is also an important pest during storage.

The morphological characteristics of the body length are 150-160 mm, the scale ring on the tail is clear, there are shorter setae between the scales, the dorsal hairs are brown, brown and brown, and the abdominal hairs are generally gray-white.

Regular rats usually hide in caves during the day, go out for food at night, go out for food twice a night, once in the evening, and again before dawn. Rats have miscellaneous eating habits, which are harmful not only to edible fungi, but also to agricultural and forestry crops, all kinds of food and articles. Agile behavior, poor vision, sense of smell, hearing, touch are very good, during the activity, slightly disturbed, immediately avoid. The young mice can reproduce after 3-4 months of life. Under the condition of adequate food, once a month, they can swim in the water.

Prevention and control measures of Poria cocos rodent damage:

The main results are as follows: 1) capture manually and put a mousetrap in the cultivation site to catch. Dig a hole to kill, pour water into the hole to catch and kill.

2) poison bait, the available rodent control agents are zinc phosphide, sodium salt of rodent, warfarin, excellent rodent control, new rodent control, etc., and 5 parts of zinc phosphide can be added to 100 parts of sorghum, corn, flour, peanuts and rice. Mix with a stick, not with your hands. After mixing, put the poison bait in the place where the rats move, put 10-20 grams of poison bait at each point, or mix it with 3 parts of zinc phosphide powder, 2 parts of tea oil and 95 parts of rice, but you can't sprinkle it directly on the fruit body.

3) can be fumigated in the rat hole, half or a piece of aluminum phosphide is put in the rat hole, then all the entrance of the hole is sealed with soil, and the aluminum phosphide tablet absorbs moisture and decomposes in the rat hole to release phosphine gas to kill the poison gas in the hole.

Commonly used agents zinc phosphide, diphacinone, warfarin, rodenticide, new rodent control, aluminum phosphide.
