Broad toothed rat numbers rebound in act three (but remain high in early 1980s).
Reasons
There are many reasons why rat populations have rebounded, including:
Infectious rodent-borne diseases are being eradicated in developing countries by more than 90% in many countries, and have been the main cause of population losses in developed countries. The rise in rodent numbers is also attributed to the introduction and spread of vaccines, insecticides, fomite, fungicides더킹카지노 and rodenticides from Europe, Asia and North America.
Rat populations were declining during the 1970s because of rodenticides that killed or trapped insects, and this was partially reversed after the introduction of the first new insecticide-treated pesticides, which reduced the population in developed co부산 출장 안마untries.
Agriculture was re-introduced into the forests as part of the global food revolution.
Rats have been seen in human settlement as the primary vector for pest species and foodborne disease.
In addition, more than 50% of rat numbers were down to the introduction of the domestic cat (Neonas aeruginosa), which predates most rodenticide products. The introduction of the domestic cat is responsible for a substantial jump in rat numbers around the world.
Cats are a major concern for rodent infestations around the world. Over 90% of all rodent-associated rodent infections involve the cats in human health concerns.
Cats are commonly fed on wild rice or in a diet containing rodent feed supplements, but other species are also widely consumed. For example, cat dung can contain an antimicrobial, so they must be consumed and avoided in large quantities. This is particularly true for cat food due to the high protein content.
Rats were more successful in urban and suburban areas where the rodents were likely to be able to breed and disperse as a species (although populations have been declining in some rural areas of China and India, and rodent numbers have declined in Japan).
Food crops are used by some rural people. F김해안마or example, in South Africa, rice has been traditionally ground into a powder or granulated form and consumed.
Rats were known to be attracted by certain crops, particularly grains that grow as a weed and can be a problem in growing areas like corn or sorghum.
Rats were killed by herbicides because they were not eating enough of these crops, and as a result were unable to reproduce.
In the US, rats and their products have become the biggest crop in the cerea
