The last issue of science popularization led everyone to understand the habits and control methods of brown rats, and this issue of science popularization to introduce the habits and prevention measures of family pest rats and yellow-breasted rats. This species is listed in the IUCN 2013 Red List of Threatened Species ver3.1 - vulnerable species, although it is harmful, but it is also endangered, you do not have to worry too much.
Yellow-breasted rat (scientific name: rattus flavipectus), also known as roof rat, yellow-bellied rat, is larger, similar to the brown rat, but thinner than the brown rat, slender body, tail length equal to or greater than the body length. Agile and strong climbing ability. It is mostly active at night, mostly at dusk and early in the morning. There is a seasonal migration habit, and when the crops are ripe in spring and autumn, they move to the field activities. Yellow-breasted rats are omnivorous, but mainly live on plant foods. Yellow-breasted rats mainly inhabit plains and some mountainous areas, and the cave structure is relatively simple, divided into simple holes and complex holes. Fertile ability is strong, but due to changes in habitat, the population is constantly decreasing.
What are the characteristics of yellow-breasted rats? First of all, it is the larger rat in the family Of Rodents, similar in size to the brown rat, but thinner than the brown rat, with a slender body and a tail length equal to or greater than the body length. The body length is 130 to 150 mm, and the weight is 75 to 200 g. The ears are long and thin, and the forward pull covers the eyes. The hind feet are slender, longer than 30 mm. Females have 5 pairs of nipples, 2 pairs of thoraxes and 3 pairs of abdomen. In addition, the dorsal hairs are brown or yellowish brown, mixed with black, the ventral hairs are grayish yellow, and there is no obvious boundary between the dorsal and abdominal coat colors. The thorax is more yellowish in color and sometimes has a white patch. The upper and lower tails are dark brown. The central coat on the dorsal of the forefoot is grayish brown and the surrounding area is grayish white, and this patch is an important morphological feature that distinguishes it from the yellow rat. The tail is well-developed, ring-shaped, with long fine hairs.
Yellow-breasted rats are generally diurnal, but predominantly nocturnal, with two peaks of activity after dusk and before dawn. Short seasonal migration is possible in residential areas and on farmland, and seasonal migration is often carried out in farmland with different crop maturity periods. According to the early and late maturity of crops, for example, the seasonal migration order of yellow-breasted rats in Rongjiang County is: pea field - wheat field - peanut field and rice field - sweet potato field - cassava field and potato field.
Speaking of which, everyone is very concerned about where yellow-breasted rats are generally distributed. In fact, it is unique to China, widely distributed in Shaanxi, Gansu, Henan, Jiangsu, Zhejiang, Anhui, Hubei, Jiangxi, Hunan, Guizhou, Sichuan, Yunnan, Fujian, Guangdong, Guangxi, Hainan and other places.
With so much to say, let's talk about its harm. Yellow-breasted rats not only destroy all kinds of clothing, furniture, stealing food and various foods in the living room, endanger crops such as corn, rice, peanuts, sweet potatoes, plantains and other crops in the field, causing serious yield reductions, but also spread epidemics such as epidemic hemorrhagic fever, scrub worm disease, leptospirosis, plague, schistosomiasis and other epidemics. Yellow-breasted rats are indoors, and the fields near the village are vulnerable, no less harmful than brown rats.
Finally, I will introduce you to the key points of how to kill rats!
Chemical control is mainly based on anticoagulant rodenticides, but the drug resistance of yellow-breasted rats is higher than that of brown rats, which is easy to leak out, so in areas with relatively high density of yellow-breasted rats, the dosage should be relatively increased. At the same time, the new object avoidance reaction and habitat characteristics of yellow-breasted rats decided that when using poisonous bait to kill rats, the baiting time and high-level feeding should be extended. Fumigation can be used on trains and ships to exterminate rats.
(1) Poison bait method: The following poisonous bait can be removed in the evening to remove voles or domestic rats for poisoning.
(1) 5% zinc phosphide bait: crush 4-6 pieces with 5kg corn or beans, mix with 500g of dilute noodle soup, and then add 5% zinc phosphide to mix well; (2) enemy rat sodium salt poison bait: use 0. 05% enemy rat sodium salt 1g mix well with 2kg of rice or cornmeal;
(3) Rat repellent bait: use 1 part of rat repellent powder 50g and 19 parts of bait: corn residue 55g or flour 350g, coarse sugar 50g mixed and mixed well; (4) Chinese herbal poison bait: fried with 20 psyllium seeds in hot oil, dried and refined, mixed with 1 bowl of fried noodles, 100g of cooking oil, add an appropriate amount of water and mix well, making bean size pills.
(2) Plugging method: use corn shaft or stalk dipped in zinc phosphide to poison paste to block the rat hole. Poison paste with zinc phosphide 12%, white noodles 13%, water 75%, first of all the oil, salt, green onion stir-fried fragrant, pour the water into the boil, and then use a small amount of water to adjust the flour into a thin batter poured into the pot to boil into a paste, to cool and then put in the zinc phosphide, fully stirred evenly.
(3) Venom method: after diluting the rat extermination medicine with 30-40 times water, it is placed in a place where there is a lack of water, and the rat is lured to eat and kill the rat. (4) Fumigation method: 3-5ml of chlorinated bitterness, injected into the cotton ball or grass ball with a syringe, the drug ball is stuffed into the rat hole, and the hole is covered with soil; it can also be put into the rat hole with 2-3 tablets of aluminum phosphide, which has excellent prevention effect.
(5) Smoke cannon method: After igniting the special smoke cannon for rat extermination, when a large amount of smoke is released, put it into a depth of 15-17cm in the effective rat hole, and then block the hole with mud, and the rat can be poisoned after 5 to 10 minutes.
