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
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.
Freezing bed bugs with dry ice is a good alternative to using chemicals in your home. If you have small children or if someone in your home has allergies, then freezing the bugs may be the ideal solution for getting rid of the
To test the hypothesis the impact of temperature on milkweed bugs, they will be placed in three different temperature conditions. The temperatures include: 10°C (refrigerated), room temperature 22°C and at 28°C. These various temperatures represent the lowered temperatures from the milkweed bugs optimal temperature (28°C). The day and light cycle for these conditions will be 16L:8D. To test the hypothesis of the effect of light regime on development, milkweed bugs were placed in 22°C condition with a 16L:8D cycle and 22°C condition with a 2.5L:21.5D cycle. About 35 milkweed bug eggs will be placed in a clear container for each treatment group.
In the passage Out to Get You Head Lice and Bed Bugs, written by Ruth Tenzer Feldman, it talks about the life spans of both bedbugs and head lice as well as how to get rid of them. It also talks about how to avoid getting them. According to the article the National Institute of Health says that if you get bitten, by either bed bugs, or head lice their bites alone, probably won’t make you sick, also that they are not attracted to dirt, but rather blood like leaches or mosquitos. Head lice’s scientific name is Pediculus humanus capitis.
Only the larva of this insect can actually eat cloth, the adults just don 't have the mandibles to do so. They have four life stages, the egg, larva, pupa and adult. The adults only live two to four weeks. The larva are attracted to animal products that contain keratin. This is a fibrous protein found in hair and skin.
The same worm (for a control variable) was placed in a forty percent mixture of Pau D’Arco (independent variable) and water for ninety seconds. Then, the worm’s heart rate (dependant variable) was recorded as before on a slide with beats per thirty seconds. As a result, the hypothesis
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 US sprays 16 million acres of Naled every year which has been linked to neurological defects which raises concern. While the insecticide is approved to be safe for crops and water supplies, it is recommended to wash produce and avoid direct contact. Although there is little risk for the environment while using Naled, wildlife is not as safe. There is threats to aquatic and terrestrial wildlife. The risks begin before the insecticide has fully broken down which does not persist for long periods of time.

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

Ouch! The constant miniature needles poking into me was not making the visit as enjoyable. Every few seconds I could hear the mosquitoes buzzing by my ears. Some also got stuck in my eyes and even my mouth! It is like my skin is their food.
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
