Dumb Cane (Dieffenbachia seguine) Stem Extract as a Rodenticide for Black Rats (Rattus rattus) PROPONENTS: Dolino, Alma Gubalane, Delsan Miquiabas, Cheryl Telen, Nikol IV- Einstein Mrs. Lalaine Biboso Research II Adviser ABSTRACT Black rats are pests and are dangerous to humans in several ways. These species are also famous for its role in spreading the dreaded bubonic plague that took billions of lives in the Middle Ages. To control them, chemical rodenticides are used but these chemicals often destroy our environment and health, and may lead to death of non-targeted organisms and even human poisoning. Dumb cane contains calcium oxalate crystals that cause the poisoning. Thus it was the concern of the study to determine whether the …show more content…
Significance of the Study This study will help people get rid of rats that are quiet a nuisance to the householders and even transmit some dreaded diseases. This will also help lessen the use of commercial chemicals used as rodenticides, which destroys our environment and health. Besides, this can also be beneficial because people can minimize their expenses. So, in this simple way, people can save money. Scope and Limitation This study was only limited on the effectiveness of dumb cane stem extract in killing house rats. Its effectiveness was measured by counting the number of rats killed in 2-6 days after they were fed to rats. The dumb cane extracts were mixed with chiffon cake. The actual observation and counting were done at an interval of 2 days. Each treatment was given 3 replications. The commercial product which was the control was Raccumin. Dumb cane stem were taken from the house of one the researchers. This study was conducted at the DOST Laboratory at the barangay hall of Calumpang compound last July 29, 2005. CHAPTER II REVIEW OF RELATED LITERATURE This chapter gives the background and the related information about the study. Dumb Cane Dumb cane (Diffenbachia seguine) is a shrub, and a native to the West Indies. Its common name derived from the fact that if its stem, which contain

People already know that rats are very disgusting creatures that live in sewers and eat trash. But these four articles introduced new insights to the problems that rats cause. Some of them include causing destructive infestations, horrible diseases that can harm or kill people and pets, and the danger of using pesticides to humans. The first reason and paragraph discusses what rat infestations are and why they occur, the second paragraph talks about the dangers to human society, and the third paragraph discusses the ways people are trying to rid their lives of rats.
To tested the effects of this plant, a research study was conducted through an online survey among college students. A group of undergrad college student was randomly selected through email from a large university in southwestern Unites States to participate. The study procedure was an online survey, with based questionnaire on college student’s achievement, lifestyle, alcohol, and other drugs behavior if a user of drugs. The data was base on the usage of drugs within the two semesters of fall 2006 and spring 2007. To get respondents to participate, rewards were offered for anyone who
Rat infestations have swarmed throughout the world, looking for food, and spreading diseases, so of course people attempt to get rid of them. First off, they spread disease. It states in Source 1, “Around 60% of the rodents carry Weil's disease...” This quote states that the majority of all rodents, have Weil’s disease. That means that if you see a rat, it is probably infected with disease. This is incredibly dangerous for people walking the street, or someone without a home. That person who does not have a home, could get a disease very easily. The rats can carry disease and they can spread that disease, it even states in Source 4, “It was this rat which ushered in the Black Plague.” In this piece, they are speaking of Black Rats. These rats were probably one of the unlucky 60%, or it was a carrier something that was on them.
The rodent problem has grown in New York City vastly in the last decade; according to Jonathan Auerbach a Columbia doctoral student in his statistical analysis on 2014 called “Does New York City Really Have as Many Rats as People”; there are approximately 2.02 million rodents in New York City and according to the Planning Department, New York’s population raised as 8,405,837 in 2013. If these reports are accurate, there is one rat for four humans in New York City. So, the problem is why New York City has so many rats and how can it decrease/eliminate the population.
An outbreak has not occurred in a long time and hopefully it will remain that way with the addition of new technology and medicine in the health department, much research and observing previous cases and more knowledge spread to those who are susceptible to the disease. It dates back many years, and is still present today. This means the number of rats, in every city, needs to be maintained and carefully watched. We need to be more cautious of cleanliness within our homes and public areas as to not attract
When rats carry diseases they become a great threat to other lives [dogs, cats, and humans] (Davison, Source 1). This was seen when the Black Death wiped out 30-60% of Europe’s population during the late Middle Ages. In source 2, by Victoria Gill it states, “A once in a generation, gigantic plague of rats, that ruins crops and leaves people starving.” This is a that is a danger because humans could starve to death without food. Rats are eating and destroying important items in your house (Schattenberg, Source 3).
The pesticides used on rodents are called insecticides that attack an enzyme called acetylcholinesterase which attacks the nervous system. They are so harmful that they can even kill a human with a decent enough dosage. The chemical doesn't just pass through the organism, it accumulates
and is a stimulant of the central nervous system. It is a bitter alkaloid C8H10N4O2 also found in cacao
Rats, are they friends or foes? This paper will unlock the mystery to rats and what's beneath their furry little faces'. We will determine if they're our rivals, our allies, or possibly both. Many believe them to be mean and vicious. Others believe they're sweet and make incredible pets. Can they both be true?
Rats proclivity towards the human condition of surplus food supplies and trash production created a system whereby these rodents cohabitation with humans, to the displeasure of the humans, was greatly supportive of large rat populations (McCormick, 2003). In his 2003 study, McCormick goes into great detail surrounding the intimate relationship between human urbanization and increasing rat populations. These animals, did not only survive, but thrived on continued interaction with human created systems of roads, cereal storage, waste disposal, and climate controlled housing (McCormick, 2003). This parasitic relationship clearly makes some institutional controls available in a more domestic case less viable, but can still be mildly controlled as seen in modern steps towards urban sanitation including widespread eradication of rat population in modern cities (McCormick,
History reveals the traditional usage of blackberry fruit, leaf, bark and roots by the Romans and Greeks for healing numerous health conditions ranging from a mild infection to venomous bites. The fruit is effective against the development of cancer including lung cancer, colon cancer, and esophageal cancer. The micronutrients present in blackberries exert chemopreventive effect and prevent the proliferation of malignant cells.
Rodents can be found everywhere on earth. Among the several different types of rodents, the ones that mostly prefer to live near humans, being the most numerous, are the mice and rats. They live in colonies which comprise of complex hierarchies, wherein they form deep bonds, often putting their own lives at risk to save family and friends. Their best habitats are cavities, holes inside walls, in sewer pipes, in stores where foodstuffs are kept, in the fields and in garbage dumps. As a matter of fact, they love to live anywhere food is available and is convenient for them to put up a nest. In addition, they can easily adjust to any kind of climate and even wipe out original mammals occupying the same niche.
New york is probably known as one of the most rat infested city. There are many programs that try to end the rat dilemma, but the rat population is so large that it’s hard to control. Not only are rats found on the train, they are also found in neighborhoods such as the Bronx. Many people complain about the rat situation to the city, but the homeowners take no action when it’s time to clean up their own mess (Bragdon et al., 2007-2009). Many of the rats that are seen all over the city are huge, and go crawling around for any food that they can find, mainly in trash cans.
