Skin Repellent

LITERATURE REVIEW
Repellents and Treated Fabrics Researchers in the 1960’s from the U.S. Army Medical Research Unit conducted a comparative efficacy test of Diethyltoluamide skin-application and M-1960 impregnated-clothing against mosquitoes in the nipah palm-mangrove swamps of Malaya (30). In this study, it was shown that the combination of skin repellent and clothing treatment provided the best protection against mosquito bites. Use of skin repellent was effective at preventing bites to the skin but this resulted in an increase in mosquitoes landing on the untreated uniform and biting through it. Solely treating the uniform with repellent had a similar effect, driving the mosquitoes to the unprotected skin areas. This experiment required …show more content…

This study used both knock-down cone tests along with arm-in-cage repellency tests against Aedes albopictus mosquitoes. These combinations along with microencapsulated mixtures extended washing durability when compared to the conventional treatment method. Their results indicated promising methods for future impregnation techniques. In this study, the volunteers inserted a forearm treated with a test sample into a cage containing 400 laboratory reared mosquitoes to test for …show more content…

SPECIFIC AIMS
This study will investigate the mosquito bite protection provided by fabrics treated with two different concentrations of picaridin as compared with the current US Army permethrin factory-treated uniform. It will focus on the following specific aims:
1. To count the number of successful blood meals adult female Aedes aegypti mosquitoes complete by biting through fabrics treated with 18 ml, 36 ml concentration of picaridin, the standard US Army permethrin treated fabric, and an untreated fabric.
2. To count the number of successful blood meals adult female Anopheles gambiae mosquitoes complete by biting through fabrics treated with 18 ml, 36 ml concentration of picaridin, the standard US Army permethrin treated fabric, and an untreated fabric.
3. Compare any difference between bite-through (bloodfed) counts of the two picaridin treated fabrics vs. standard Army permethrin treated fabric by the two mosquito

    An alternative hypothesis was that there is a significant correlation between the amount of fruit flies collected with the 0.5 mg methyl eugenol and just the eugenol control. According to Table 3, the amount of fruit flies collect in the 0.50 mg of methyl eugenol was higher than that of the eugenol control (e.g. trap 1 had 39 flies in contrast to 50.0 in the control). After calculating the p values using the t-test, the data indicated that there was significant difference and the null hypothesis was rejected. A null hypothesis that was rejected indicated that the p-value was lower than 0.05 and the critical value (t-value) was above the indicated t-value. Although the p-value was higher than 0.05 with a value of 0.09, the critical value of 2.2 was above the value indicated by the degree of 4 which had a value of 2.132.

    Then test tubes A and C contained bromine. Test tube A was placed under the light and test tube C was placed in the dark. After the reactions occurred, test tube A was the only test tube that contained a white solid and was vacuum filtered. It was then washed with DCM and the leftover substance was the product. Capillary tubes were then obtained and filled with the solid product.

    When Jeannette was visiting her friend’s home in Battle Mountain, her friend “pointed toward a shiny gold contraption dangling from the ceiling, which she proudly identified as a Shell No-Pest Strip… I went home and told Mom we needed to get a No-Pest Strip like Carla’s family, but she refused. ‘If it kills the flies,’ she said ‘it can’t be very good for us”’ (64-65). Jeanette’s mother doesn’t want to buy the no pest strip because she wants to preserve nature which seems fine because the lizards will eat the flies, but by doing this she has caused her home to be infested with flies and lizards and decline the family’s living conditions severely. While the Walls home in Phoenix was infested with cockroaches and termites, Jeanette “suggested we buy roach spray, like all our neighbors did, but Mom was opposed to chemical warfare…

    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.

    For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.

    T. Coraghessen Boyle’s tone in his narrative “Top of the Food Chain”, conveys a casual conversation with a senator about the use of DDT in Borneo. This casual conversation also exemplifies his casual and reckless approach to the solution of insects plaguing the people of Borneo. Boyle’s passion blindfolded reasonable and reliable alternatives to help the insect problem. The ramification of dealing with the pesky insects causing disease and burden to this developing country were ill-researched and exemplifies Boyle’s casual approach and tone. Boyle’s passion to help a “2 year old so black with flies and mosquitos it looks like he’s wearing long johns”, blinded all reason to do good research and understand the risks upstream when mosquitos and

    Bed Bug Summary Bed bugs or more specifically Cimex lectulatius are blood drinkers that have had major population increases across the globe in the past ten years. Bed bugs can cause many skin syndromes due to the fact that they feed on blood making them relevant in modern health. Prolonged exposure to bed bugs can lead to chronic blood loss, anemia, and many psychological disorders. Bed bugs are active during the night and select hosts randomly except when they are in close proximity to a host. At that point it is believed that bed bugs will be drawn towards heat and possibly carbon dioxide.
