Mosquitoes are common disease vectors for such illnesses as avian malaria, yellow fever and encephalitis. Together these illnesses kill literally millions of people per year, partially because mosquitoes are such a hardy and tough family. Was the scientific community to know more about a mosquito's life parameters, better and more efficient method of controlling mosquito population could be developed. The rapid bombardment of sound waves that accompanies high hertz and decibel levels will stunt and even stop development of the Culex pipiens larvae, creating a more efficient, environmentally friendly method to control mosquito populations.

Methods/Materials: The Culex pipiens arrived when they were in the larvae stage. They were placed, along with roughly 1 ounce of dried liver and yeast, into 2.48 liters of tap water contained within a glass container. The container was placed within a sealed room, whose temperature stayed within the mid-70° Fahrenheit. The room received extremely limited light; the larvae received less than 4.5 hours a week of light.

Results: Though at one point there were nine living adult mosquitoes and around 240 larvae, all the mosquitoes died within one week. The adult mosquitoes died first, with 66.7% of them dying in the first two days. At the end of the week, 100% of the mosquitoes were dead and 16% of the larvae population had disappeared. By the 28th of February, the population of the larvae had descended by 97.5%. Conclusions/Discussion The mosquitoes didn't survive for a variety of possible reasons. One reason was the lack of light. Another conclusion could be due to the storage area I used for my experiment. There was a range of diverse chemicals within the closet that could have escaped and either killed the mosquitoes or combined with other chemicals to kill the mosquitoes. Finally, there is the possibility that some unknown microbe invaded the mosquito culture and infected the mosquitoes' food/water source. All of these explanations need further experimentation to determine their validity and viability in the outside world. Summary The experiment was designed to test the health effects of different frequencies (hertz), pitches (cycles per second) and amplitude (decibels) on developing mosquitoes from the species Culex pipiens.
