Q1. Entomotoxicology is the use of insects on decomposing corpses to determine and quantify the drugs which had been consumed by the individual prior to their demise. According to Campobasso (2004), as the maggots feed on the corpse, they consume the drugs available in the body, which can affect their growth or complicate their life cycle. He describes how maggots from different corpses which had been proved to have different amounts of drugs such as morphine varied in their development cycle and general characteristics (Campobasso, 2004). This claim was further supported by De Carvalho (2012) in which the study had shown that the presence of morphine in the maggot body would cause the acceleration of its development. However, these concentrations …show more content…
First, they can be infected with disease agents such as bacteria or viruses which will be transmitted to the human targets (Pate and Cameron, 2003). Secondly, the arthropods can be used to attack crops and livestock so as to cause crop destruction which leads to severe economic loss and starvation etc. For example, insects such as Eastern Lubber grasshoppers could either directly feed on the cultivated crops or cause an infection to the crops (vectors). Thirdly, the stinging insects such as bees and wasps etc. could be used to directly torment the targeted population. They could attack the local people to cause pain and distress, which is equally threatening just as disease conditions, hence it should be prevented in order to preserve family bonds (Pate and Cameron, …show more content…
For example, CRISPR technology can be used to create genetically modified “Killer Mosquitos”, which cause plagues with a capability of wiping out staple crops and cause food deprivation (Kaufmann, Meltzer and Schmid, 1997). It is possible to design other agents which could cause even more damages to the targeted population. For example, during the cold war in the 1950s, the United States Army designed an entomological warfare laboratory that could produce 100 million of mosquitos infected with Yellow Fever virus (Mattingly, Crosskey and Smith, 1973). The army tested the impact of this ‘entomological weapon’ by launching the uninfected mosquitos over its cities such as New York. No Yellow Fever was noted, but up to 92% of the residents in the targeted cities were under attacked by the mosquitos (Peterson, 1990). This, therefore, proved to be biologically risky and capable of causing a lot of distress to the victims. It was tested by the best and was observed to be a great risk if it falls into the wrong
Dr. Martin Luther King Jr. writes the letter to Birmingham jail to address the biggest issue in Birmingham and the United States at the time. The letter describes the injustices happening in the black community of Birmingham. Martin Luther King Jr. uses appeals to emotion, ethical appeals, and logical appeals to justify his desire for racial equality. Rachel Carson wrote “ The Obligation to Endure “ to enlighten humanity on the atrocities being granted upon earths biological systems, and the harmful mutating chemicals that will potentially effect the future generations and their health. Carson addresses these understandable concerns using logical, emotional, and ethical appeal.
Get Rid Of Bed Bugs By Freezing Them Out Pesticides may not be as effective on bed bugs as they once were because the bugs have developed a tolerance to many of the chemicals. However, it 's possible to kill the bugs in other ways, such as freezing. You can freeze some belongings yourself in your home freezer if it is cold enough, or you can hire an exterminator to do the job. Here 's how you freeze out bed bugs. Using Your Freezer In order to kill bed bugs, your freezer should drop to at least 0 degrees Fahrenheit.
By the end of the experiment, it became clear that the pill bugs preferred the environment consisting of dirt over the other
Although they may be small in size, they have had a significant impact on human activities in terms of agricultural production and in the same way it can be observed that human activities have impacted this species in terms of optimal conditions for reproduction and growth. Globally, invasive insects cost an estimated $2. 1 billion in forest damage and $13 billion in loss of crop depending on how detrimental the species is but nonetheless, a species such as the love bug demonstrates that even nuisances can provides benefits amide the costly
The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants.
For example, genetic engineering can lead to overpopulation by expanding the lifespan of humans. On the third page of Pros and Cons of Genetic Engineering in Humans by Matt Bird, Bird states “Genetic Engineering’s ability to expand life has a drawback in that it can cause overpopulation. The Earth is already showing the strains of supporting too many people at once, and preventing natural death can have serious implications for employment, living space, food and energy sources and much more beyond. ”In The Giver, the elders used genetic engineering to make everyone colorblind.
So each time one insecticide becomes outdated, a stronger and more poisonous one is made. Another issue that has brought about an expansion in the insect populace is the worldwide migration of plants and insects. Each year, the United States imports many plants from other countries, so far they have introduced over 200,000 and 90 major insect enemies of U.S plants have come from these introduced
Nicholas Hack-Irvin Bio 104-06 October 25, 2015 Earthworm Response to Spicebush Methods: Using a plastic container lined with wax paper, two pieces of construction paper were cut to each fit the width of the box. These two pieces of construction paper were placed in close proximity to each other to ensure that both sensory feedbacks would be noticeable to the earthworm when placed in between the two pieces of paper. One strip of paper was lightly covered in water, where the other piece of paper was lightly covered in spicebush extract. 10 replications were performed where a different worm was placed in the center of the container each time, equidistant from both pieces of construction paper, and observed to see whether it would move towards
The issue of modification through gene manipulation becomes increasingly complex when considering how this technology can be used as a means to unethical and harmful uses. In the article, Babies with Genes From 3 people could be Ethical, Panel Says, Rob Stein exposes various concerns about three gene donors in an embryo, including how a scientist, “Could introduce some new disease into the human gene pool or that scientists could try to do this for other reasons-nonmedical reasons, like create designer babies where parents pick the traits of their children.” Stein goes on to explain how the gene replacement procedure would take place, which continues to usher in a plethora of concerns as whether to allow Crispr technology be tested on a embryo.
The hands were washed. Goggles were placed on the eyes for extra protection. A petri dish containing nine pill bugs were obtained and set aside for later use. Two water bottles’ ends were cut and taped to each other creating a miniature tunnel for the pill bugs to crawl in. 50 mL of tap water was obtained in a small beaker and then was slowly moved into the lid of the bottle using a funnel.
First, the government's fear controls the inhabitants to cause genocide. Earth's fear of the Buggers gives them one priority, kill them all. The Buggers attack on Earth outrages many. The humans support any efforts to hurt the Buggers in any way, even though humans have no idea what they wanted in the first place. The government feels the need to please the people because not a lot gets accomplished when the humans keep thinking about a possible Bugger invasion.
Firstly, Carson uses horrific examples to grab the attention of her audience. She tells her readers about chemicals, such as pesticides, that are destructive and how they are used on all kinds of foods as well as how they are used to kill bugs. Carson explains in her essay how the war on bugs may never be won. She states “…insects, in a triumphant vindication of Darwin’s principle of the survival of the fittest, have evolved super races immune to the particular insecticides used, hence a deadlier one
The of use maggots to aid wound healing – known as maggot therapy (MT) or maggot debridement therapy (MDT) is a type of biotherapy that has been reported since ancient times. The Old Testament cites the infestation of a wound with fly larvae – “My body is covered with worms and scabs, My skin is broken and festering.” (Old Testament, Job 7:5, NIV Version, 1984). The benefits of this biotherapy have been recognised for centuries; Grossman states “since ancient times, fly larvae have been deliberately introduced into wounds to promote healing” (Grossman J. Flies as medical allies. The world & I. October 1994;187-193) and goes on to state that this method was practiced by aborigines in Australia, Hill people in Burma, and
Some of the forensic and pathology experts cast doubt on coroner John Penistan’s key forensic evidence used to convict Truscott.” This case haven been taken many years ago had many doubts surrounding it, “in 1996, Penistan had second thoughts and published a review of his autopsy that opened the time frame to a 12-hour window.” Since the forensic evidence was the determining factor for Truscott’s conviction, many years later there was more research done. Dr. Neal Haskell, a forensic entomology professor “testified that larvae must have been deposited on the 12-year-olds body between 9pm and 9:30pm.” With that being said this put weight on the time interval Penistan originally stated.
Birth Defects: Birth deformities from pesticide presentation is an alternate developing sympathy toward expecting moms, grown-ups and kids. The connection in the middle of pesticides and conception deformities has been fixed to utilization of family unit spreads that execute enclosure bugs, ants, mosquitoes and insects. These intense chemicals are utilized to assault the sensory system of creepy crawlies and slaughter them, however may represent a significantly more serious danger to your unborn child's wellbeing and expand the danger for oral clefts, neural tube imperfections, heart deformities and appendage imperfections. Introduction to pesticides and insect poisons ought to be evaded no matter what amid pregnancy.
