Voles have strong fertility, a female vole can give birth 6 or 7 times a year, more than a dozen or twenty each time, mice can give birth in three months, see how fast? If left unchecked, rat infestations will become rat plagues, and the world will become a rat world. But voles have a habit of intraspecific struggle, voles in a place more than a certain density, this intraspecific struggle will occur, vole population will appear a large area of liver degeneration and nervous disorder, fighting each other, resulting in a sharp decrease in the number of populations, and eventually reach the balance of accommodation. This habit is also a great blessing for people. A vole can consume several kilograms of grain a year, and the highest stock of voles in China reaches 3 billion, damaging tens of billions of catties of grain a year. Crops such as cotton and sugarcane are also suffering. People's hunting behavior of voles' natural enemies, owls, weasels, snakes, etc., has made the harm of voles increasingly serious. In addition, voles are also carriers of more than 70 disease pathogen viruses, which are a great threat to human health. Therefore, the control and management of the harm of voles should attract sufficient attention.
Voles are also rampant too much, some diligent vole holes can dig out more than fifty pounds of grain, are some peanuts soybean rats stored in the winter to eat, nothing to go with my dad to dig the vole nest, really a physical work, there is a kind of vole where we call "Tianjing", a nest has several holes, generally there is a largest main hole diameter of about 10 cm, is its transportation route, vertically down nearly a meter, a meter below the beginning of the fork, large hole fork small hole, hole even hole, hole set hole, true and false hole, true and false hole, Generally there are several bedrooms (dig a look to understand, covered with a variety of feathers and leaves weeds), there are toilet holes, storage room holes are at most and the largest, some are more than 20 centimeters in diameter full of grain, there are some strange holes that do not know what to do, some can reach a depth of two meters, and there are several escape passages, really intricate, really can be described as the textbook of tunnel warfare!
There are many species of voles, different rodents, and different burrows.
Black-tailed prairie dog rat, meadow field mouse, shaded ground squirrel
Black-tailed prairie dogs, meadow voles, ground squirrels, cave-dwelling owls
Mole cave
Many rat holes are not dug by only one vole, but the result of the joint efforts of many voles, and the highest vole burrow on the "floor" can reach six floors. Vole burrows are related to food, environment, and species of voles. Different species of vole burrows have different shapes and arrangements
Some voles survive by hunting other clams that invade their territory. The size of a vole's burrow depends on the abundance of food on its territory. Vole burrows that live in grassy pastures are much smaller than those that live in dryland sour soils. An adult vole can dig out a network of more than 7,000 square meters of crisscrossing multi-layered caves, and the highest "floor" of the vole cave can reach six floors. But no matter how winding their network of caves, they will eventually lead to the luxurious "grain depot" of voles.
Species of voles: A generic name for the rodent hamster family, but in general, those who live in fields and grasslands are voles.
Mo's voles, also known as swamp pond voles, are mainly found in China, And are common in Inner Mongolia and the three northeastern provinces, mainly inhabiting grasslands and shrublands, and are one of the main pests in the northeast forest area. The nest area of Mo's voles is generally 452 m2, and the nest area of wintering male rats can reach 1874.46 ±539.31 m2. This largest phenomenon in the nest area occupied by male rats is also present in other rats such as haddock rats, root voles, Bryde voles, etc.
The wild rats in the Dongting Lake area are called "Oriental Voles". In the past two years, there has been no major flood, and wild rats in the lake area have been breeding in large numbers. On June 20, 2007, the Three Gorges Dam was released more and more, causing the water level of the lake outside the Dongting to rise, and rats flew out to form a rat plague.
Oriental voles are larger voles with round heads and a body length of 12-15 cm, which are widely distributed in China, with a distribution area as far north as Heilongjiang Province and south to Guangdong Province. Oriental voles go out day and night, and are still more active at night. The oriental vole once nibbled on the bankers on a large scale, causing great losses.
Buzian voles, Chinese alias sand yellow voles, prairie voles, brandet voles, Brandet voles, hamster mammals, one of the main rat pests in the grasslands of Inner Mongolia, China. Its activities not only directly affect the growth of plants on the grassland, destroy vegetation, and expose the land, but also its excavation activities change the soil structure and micro-terrain of the Dongkou group area, so that the vegetation in the Dongkou group area evolves in a direction that is not conducive to grazing. It will take 3-5 years to recover after abandonment, which will seriously affect the development of animal husbandry.
The squirrel resembles a vole, is small in size, and has a diurnal and active lifestyle. Feeding on the leafy parts of plants, the main predators are ferrets, foxes, wolves and beasts of prey. It is found in Sichuan, Yunnan and eastern Tibet; it is found abroad in northern Myanmar.
The mole-shaped vole belongs to the genus Vole family, vole genus. Shaped like a mole, it is similar in size to a vole, with a total length of about 100 mm, and has a series of morphological structures adapted to the life of underground caves. It is mainly plant-based food, gnawing on roots and underground parts. It is mainly distributed in Xinjiang, Hexi Corridor, Xiahe and other places, and is also distributed in Mongolia and the Soviet Union.
Root voles are medium in size, slightly larger and stout than ordinary voles, and are distributed in Gannan and Qilian Mountains. It is found in Xinjiang, Qinghai and Shaanxi. It is found in Mongolia, the Soviet Union, westward to western Europe.
In that era of extreme poverty, starvation in the vast countryside was a frequent occurrence, and the grain of large collectives was very expensive and could not be wasted. After the autumn harvest, our mischievous children began to let go of people and horses to carry out large-scale hunting of voles, one is that the captured voles can improve food, and the other is that the grain seized by the voles' nest can be shared with their families. Voles are rodents, similar in size and fur to house mice, with yellowish coats, day and night, often haunting the fields, destroying crops, stealing grain, and are good at burrowing and storing stolen grain. Voles are afraid of water, so when building nests and repairing caves, they will choose high and dry places, the cave is a convenient path for entry and exit, the cave is a place to live and live, and the depth of the cave is unequal: shallow is 1-2 meters, and deep is several meters without bottom. Because our rat hunting is mainly the way of filling the cave in the past (you can also use the rat clip and the wire sleeve, but the effect is not good) sometimes the filling does not see the voles for half a day, which shows the cunning of its nature and the solidity of the cave fortifications. As long as it is a shallow source cave, it can be dug up to harvest some grain, and then the deep one will be empty, and it is impossible to dig anymore. The caught vole has its skin peeled open and its flesh can be stewed or grilled, and its taste is very delicious. Swan-catching pigeon meat weasel (vole) is high-level, and the average person can't eat it. In recent years, the number and breeding rate of voles seem to be not as high as in the past, perhaps because of the large number of cats!
