The scientific name Eutamias sibiricus (Laxmann) belongs to the order Rodentia and family Muridae. Also known as Five Eyebrows, Flower Li Stick, or Flower.

Host vegetables, field crops, ginseng, insects, bird eggs.

Harmful characteristics: preferring to eat seeds, nuts, and berries. In spring, we often dig and eat the seeds sown in farmland, and in autumn, we steal and store grain.

Morphological features: Small in size, approximately 140mm in length, with cheek pouches, prominent earshells, and no tufts at the end of the ear. The tail length is close to the body length, with slightly fluffy tail hair and long end hair. The whole body is brownish gray yellow, with the latter half being yellowish compared to the front half. The back hair is light yellow or orange red, with 5 black brown vertical lines, hence the name "Five Eyebrows". The belly hair is dirty white, the base is gray, the tail hair is brown, the middle is black, the tip is white, and there are white fur edges around the tail. 4 pairs of nipples. The head is narrow and elongated, the skull is not protruding, and the zygomatic process of the maxilla is horizontally flat. The chewing surface of the molars is almost prototype, with indistinct thin longitudinal ridges on the anterior surface of the upper and lower incisors.

Living habits inhabit plains, hills, broad-leaved forests, coniferous forests, and areas with multiple shrubs, as well as mountainous farmland. Caves are often made in forest areas, such as fallen trees, tree root bases, deep ditches and crevices, and stone crevices. The tunnel structure is simple, about 1 meter deep, and the warehouse and nest are integrated. The lower part stores grain, and the upper part uses grass to make a nest. There is a grain storage pit near the cave, which can store 30g of grain. The flower rat nest is spherical or bowl shaped. During the day, one should first climb to high places in the morning, such as trees, tree stumps, fallen trees, etc., to observe the surrounding movements and then jump into the ground to cause harm. In mid July, the peak period of harm will enter, and one should be agile, curious, and good at climbing. Annually giving birth to 1-2 fetuses, with 4-6 offspring per pregnancy, and one month for pregnancy and one month for lactation.

Prevention and control method (1) Shooting method: Before the flower rat harms the ground, observe the movement on the tree first, and then use a bird gun to shoot it. (2) Set aside a 2-3 meter distance around the severely damaged area, nail wooden stakes and use iron wire to pull wires, tie dogs and run back and forth along the iron wire, which can force flower rats to climb trees or escape, reducing the damage. (3) The poison bait method is used to take shelled peanuts. First, take out the peanut kernels, dig holes in the kernels, inject a small amount of zinc phosphide, seal the holes, and then put the peanut kernels into the shells and place them in areas where flower rats often appear; Or put zinc phosphide into the fried cocoon pupae to make poison bait; Stir fried corn germ sugar can also be used, and the mixed medicine can be found in the prevention and control methods for black striped mice. At present, the alternating use of acute and chronic rodent drugs has a good effect. Both acute and chronic rodenticides have good effects on rodents in farmland, as well as on crop seedling protection. Alternating use can prolong the emergence of the first generation of anticoagulant resistant mice, which can maintain the advantages of high chronic drug efficacy, long efficacy, and good safety, while also leveraging the characteristics of acute rat poison, such as fast rat killing, early efficacy, and food saving. Combine rapid extermination with long-term control of rodent infestations. In areas with low density of rodents in farmland, acute and chronic rodenticides can be used alternately between years for prevention once every 1-2 years; Chronic drugs should be used twice a year for rodent control in medium density areas in spring, and acute drugs should be used alternately in autumn; In high-density or epidemic areas, for spring rodent control, acute drugs should be used to lower the base first, and then chronic drugs should be used to sweep the residue, achieving continuous alternating use, which can maintain a low-density state for a long time. For specific methods, please refer to the black striped mole mouse.
