Bed bugs, known as Cimex lectularius L., are blood-sucking insects that dwell in homes, hotels, and basically anywhere. In order for the bed bugs to survive and grow, the bug feeds on blood. The best time for the bed bugs to come out and retrieve their daily dose of blood is at night, which is controlled by the circadian rhythm. During the bug’s nightly routine, the bug is triggered by carbon dioxide released by the humans and comes out of its hiding place to seek a victim. The heat produced by the victim attracts the bed bug onto the bare skin. As soon as the bed bug is on the victim, its rostrum pierces the skin and sucks out the blood within 10 minutes. Side effects of getting bit by a bed bug include: itchiness, rash marks, and psychological …show more content…
All of the chemicals and solutions conducted in the experiment were either from Pierce/Thermo Fisher Scientific or purchased from Sigma-Aldrich. Many of the concentrations were diluted in water or heated to a certain temperature to see how bed bugs would react to these different solutions. Scientists conducted two experiments to see how bed bugs reacted to different concentrations. The first experiment bed bugs were treated with adenosine nucleotides such as ATP, ADP, and AMP. After collecting data, the results show that there was little to no difference between bugs engorging on blood and ATP. Also, the same effect applied to low concentrations of ATP and phosphate-buffered saline when offered to male bed bugs. This experiment revealed that bed bugs engorged more than 80% of ATP, 40% of ADP, and less than 20% of AMP. Which means that ATP had the highest effect on bed bugs than ADP or …show more content…
Different groups of bed bugs were offered 3%, 1%, 0.1%, and 10% of NaCl solutions, however, none of the bugs reacted to the 10% solution. The 3% NaCl solution was engorged the most by male bed bugs. Which we can say that bed bugs are fastidious insects, because the higher percentage of the solution the bed bugs will not have the ability to survive. Same concept goes with the lower percentage of the solution. Bed bugs do not react fully when offered a low percentage of solution, therefore, the bug would rather engorge on a solution with a medium percentage. Scientists also detected that solutions containing albumin, globulins, amino acids, vitamins, and cholesterol had a lower rate of being engorged. To further understand how bed bugs feed on blood, scientists also tested chemicals that are found in the blood. Bed bugs have both innate and fixed action behaviors. Innate behavior is known as instinct behavior, which the bug’s instinct is to feed on blood. Fixed action behavior is define as triggered instincts, which carbon dioxide and heat produced by the host triggers the bed bug to suck on the blood. Another study have shown that triatomines, Aedes, Culex pipiens, and Simulium venustum responded highly to AMP rather than ATP. Thus, assuming that bed bugs and adenine nucleotides come into contact at the biting site, but apyrase in the bug’s saliva does not recognize this reaction. Many scientists hypothesize

Corotto, F., Ceballos, D., Lee, A., & Vinson, L. (2010). Making the Most of the Daphnia Heart Rate Lab: Optimizing the Use of Ethanol, Nicotine & Caffeine. The American Biology Teacher , 176-179. The purpose of this article was to test the effects of chemicals on Daphnia magna.
According to Yong, Coffee Berry Borers are beetles that can make holes into coffee berries and lay eggs in the bean itself. The experiment was to see why the Coffee Berry Borer can withstand caffeine while other beetles clearly can’t stand its own with the poisonous caffeine. Ceja-Navarro and his team set up an experiment where they tested the beetles by first examining the feces of their normal diet. Then they promptly fed the beetles with an antibiotic and once again examined the feces. The feces of the beetles that were fed antibiotics was chock full of caffeine.
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.
This is important because before potentially harmful products are tested on humans, they should be tested on the worms. First, a pre-test hypothesis (Pau D’Arco is a stimulant) is made about what a certain extract (Pau D 'Arco) will do to the worms heart rate. A worm was chosen and put into a cup of conditioned (unchlorinated) water to sit for ninety seconds. The worm was very squirmy and active during the ninety seconds. It was put on a slide, and three separate tests were taken to determine the control group heart rate.
Mosquitos in particular. “ He had come through the crash, but the insects were not possible. He coughed them up, spat them out, sneezed them out, closed his eyes and kept brushing his face…All biting, chewing, taking from him.” (Paulsen, 2007:39) These bugs were testing Brian’s resilience and willingness to survive.
The most affected creature are the bees that are coming into contact with the insecticide. The aerial spraying in North Carolina resulted in the death of millions of honeybees. The product used, Trump, which contains the pesticide Naled, is labeled to be highly toxic to bees. Many beekeepers were not warned about the aerial spraying which resulted in the loss of their colonies. Juanita Stanley stated: “Now, I 'm going to have to destroy my hives, the honey, all
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.
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.

Bugs can be a nag. They often cause a household’s mood to be a drag. Not only do they cause embarrassment, they deteriorate health and comfort levels of individuals who have to co-exist with them. There should be no human core-existence with any other species that can harm us in any way. If bugs are allowed a comfortable stay at your house-hold, friends will flee you and children will do anything than stay home.
The invertebrates ate the bait trap and their habitats were contaminated from bait residue, as well as the by-products and carcasses of other animals. The poisoned insects also lead to secondary poisoning for the animals that prey on
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
Although human hosts are the main source of blood meal for the insect, other wild animals such as birds and reptiles can become infected as well. (Cdc.gov,. ' CDC - Chagas Disease - General Information - Vector Information' July 19,2013 Retrieved from http://www.cdc.gov/parasites/chagas/gen_info/vectors/index.html#list) The human host then scratches the bug bite causing an open wound, getting the parasite into the bug bite hole or subsequently getting it on their hands and into a mucous membrane. “Meta acrylic trypomastigotes reaches the bloodstream and enter various cells such as muscle cells, macrophages, neurons and epithelial
Grasshopper in a group are subject to attractive three forces based on combined sensory, chemical, and mechanical cues that affect their motion. These forcess represent the grasshopper swarming behavior and they are: 1. Downwind advection force 2. Social interactions force 3. Gravity force There are N grasshoppers in the swarm group, and the ith grasshopper has position xi.
