It is said that, “The smaller the creature is the more havoc it is likely to create”; the rodents present in our lives are very much example of it. Rodents belong to the class Rodentia are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws which must be kept short by gnawing. The 4000 rodent species belonging to 30 families are spread all over the world. A pair of rats and their offspring could produce 1,500 more rats in only one year if they all survive.
Rats have been enjoying a close relationship with humans for hundreds, if not thousands, of years. Humans derive no benefits from having rats around, but rats get
all sorts of perks. Most notably: food, shelter and water. Often this has little effect, but in some cases, rats go too far, and their impact on human population becomes unbearable. The rodents have the history of causing damage to the belongings of the human as well as the human itself as they act as perfect and ideal host to carry a variety of viruses. The ill-effect of the presence of the rodents can affect a single person or a large group of people.
The rodents are known to cause nuisance in all sectors of human life; agriculture, transport, communication and daily life. The destruction is on the large scale when the livelihood of a region is in danger.
“By gnawing through a dike, even a rat may drown a nation”. The rats in the North-eastern region live upto the above statement.
North East India has rich bamboo culture. The different tribes inhabiting the region heavily depend on bamboos for various domestic and agricultural purposes. Their handicrafts using bamboo has gained popularity both nationally and internationally. These products are made of specific bamboos usually cultivated by the people. In recent times bamboos have been identified as a valuable industrial raw material substituting wood products and having potential for augmenting the economy.
Their utility as edible shoots is also being exploited for setting up of industrial ventures. The flowering of bamboo is infrequent and the time interval ranges from 60-130 years. The species of bamboo plantation in India flowers every 48 years. In this species the entire plantation flowers at the same time leading to abundant production of seeds. The bamboo trees die after flowering and re-grow from their seeds. The seed forms a huge source of food for the rodents. The feasting of rats on these seeds boosts their population by many folds.
The bloom in the rat population exhaust the bamboo seed supply and soon turn their attention to the other crop plantations and destroy them completely leaving the entire population in a lurch. The consequence of this is the outbreak of famine in the concerned regions. Such times are known as ‘MAUTAM’; a cyclic ecological phenomenon which returns every 48 years in the northeastern Indian states of Mizoram and Manipur, which are thirty percent covered by wild bamboo forests, as well as in Hakha, Thantlang, Falam, Paletwa and Matupi Townships: regions in Burma creating a widespread famine in those areas.
The population of rats grows so large in these areas that they are killed and used as source of food in these affected regions as their source of food was destroyed by the rats.
The famine caused by bamboo flowering was recorded for the first time in 1862 and the next bamboo famine which devastated the entire Mizo chiefdoms was recorded in 1881-1882 and 1959. In 2006 when the when the similar famine situation was encountered affecting near about 10,000 families also destroying the bamboo plantation.
The bamboo famine has caused economic and political disturbance in these regions resulting in the death of about 30,000 people. The Relief Fronts organized failed to meet up with the destruction caused. “Rodenticides were distributed by the government while farmers were asked to cultivate alternative crops which would not be damaged by rats” said James Lalsiamliana of the State Agriculture Department to Indian Express on 11th February 2011. The state government is now as a solution to problem encourages cultivation of other crops like potatoes and turmeric instead of bamboo to mitigate the impact of Mautam. But does this really solve any problem?
Bamboo are an important group of plants, which have become an inseparable part of the culture and day to day life of the people particularly those living in the rural areas of N.E. region of India. The north eastern regions of India have 29396 sq. km under bamboo cultivation. The switching of the crop won’t serve as a profitable solution. The root cause of the problem however is not the crop but the rodents.
The focus should be on the rodents and their avoidance to escape the harshness of the famine. The typical action involves use of poison to kill the rats. Such action may have a serious consequence; the poison spread around the area may leach into the soil and alter its quality as well as pose danger to growth of the plantation. They may also endanger the life of the other microorganisms present in the soil.
Ctech Corporation provides the best solution to the problem. It produces and supplies Rodrepel which is non-toxic and environment friendly. The use of Rodrepel does not kill the rodents or any other organisms; it repels the rodents using their own sensory stimulants. Rodrepel is target specific and works such that it makes the rodents repel from the concerned areas. Rodrepel are available in the form granules which can be incorporated in the mulches and films. Rodrepel is a solution which meets every requirement of rodent problem.
