*Last Updated July 14, 2022  Purpose: For my experiment, I am testing what color container and type of water mosquitos are most attracted to. Background research: During the weekly science session with Dr. Alison Parker, I learned more about mosquito habitats and where mosquitos breed. Mosquitos lay their eggs in/near water, and mosquitos in their early larvae and pupae stages live in water. This information guided me to choose my AOI coordinates in an area with standing water. The coordinates on the red line in the picture run along a ditch that leads into a ...

I am currently testing the attractability of mosquitoes to black and white, with a control of transparent plastic. This could help us determine what clothes to dress in to avoid mosquito bites, and therefore the spread of disease, when going outside.  Materials: Three 1 liter clear plastic containers One 1 liter white plastic container One 1 liter black plastic container Five wooden sticks Fish food Hypothesis: Mosquitoes will hatch more larvae inside of a white conatiner than a Black container because the white stands out more in a natural environment. I ...

Initial Setup I decided to test how sunlight and container size would effect mosquito oviposition both in terms of how many larvae and what type of larvae are found in each container. Testing For Sunlight I found two locations in the same neighborhood with very different levels of sunlight. My first location is a sunny and open back yard (with my cat): My second location is a shady backyard near a golf course: Testing For Container Size At both locations I placed a 5 gallon home depot bucket and half of a plastic water bottle to compare the ...

As my trap experiment, I'm comparing location, trap contents, and trap container (mostly the container, hence the title). I have 8 traps set up across 3 locations - 3 in one, 3 in another, and 2 in the last. Each location's traps all share an origin for the water they use and the bait they use, but each of the traps in a location uses a different type of container - either a dark blue bucket, white bucket, black bucket, or clear soda bottle. As a further variation, the soda bottle traps are much smaller that the bucket traps, giving another layer to the data. The first set of traps ...

The last 4 weeks of field trips and mosquito mapping have made me curious about the effect of water quality on the habitation of mosquito larvae in water bodies. So far, I have gone to a canal, creeks, ponds, and backyards. All these places vary in their water quality and mosquito larvae content. <--- The creek I visited had mostly clear water <--- Canal with poor water quality and lots of algae Looking beyond AOI for vector-borne disease data While my field research is limited to the area of interest (AOI), I researched New Jersey vector-borne surveillance reports ...

After reading the article "Container Type Affects Mosquito Oviposition Choice," I was inspired to test how a container's surface area, an abiotic parameter, may affect female mosquito oviposition choice (Parker et al). At first, I was really curious about how the ratio of surface area to volume in a container affected oviposition choice. Thus, I began my experiment by finding containers with different surface areas but of similar volumes so I could control the volume of water in each container and more effectively isolate whether surface area affected oviposition choice. The first ...

Conclusion:  Although no mosquitoes were found, this process has helped me understand the methodology of making an experiment and having to deal with hardships and setbacks. There were many potential sources of error both within the system of the experiment and with outside forces. Systematic errors could have stemmed from the trap design or location. The weather was a factor of random error. The weather varied across the duration of the experiment, sometimes drastically within a single week. The weather changes could have been counteracted with more frequent checking of the ...

I decided to test the impacts of fertilizer on mosquito breeding habitats. Background: I live in the Tampa Bay Area in Florida, and a major issue facing our ecosystems is fertilizer entering our waterways from runoff after people fertilize their lawns before it rains. This can lead to major algae blooms, like red tide, which are harmful to the rest of our marine organisms. Just last year, there was a particularly dangerous bloom that led to a fish kill where our waterways were littered with millions of dead fish. However, the Tampa Bay Area contains more than just marine ...

NYC is very hot and stuffy in the summer, but also has a lot of shade. A large part of this shade comes from large buildings, but most blocks have trees and there are some notable parks with a lot of tree cover as well. I get bitten all the time in the park when not in direct sunlight, but not so much when I'm downtown with the same level of shade.  I wondered if there was something to this natural shade (from trees) vs artificial shade (from buildings), or if the park in general was just more conducive to mosquito growth. I also added cute little PLA 3D Printed frogs as ...

Background: I live in a suburban area around 30 miles south of San Francisco in the West Bay, near the wetlands/the bay. Our county regularly treats the wetland trails for mosquitoes, and they also do aerial treatment, especially in the spring when mosquitoes like to breed. Many previous literature papers concluded that mosquitoes prefer to oviposit in slightly alkaline water; as such, I predicted that there would be a higher abundance of mosquito larvae in the alkaline water. To make an alkaline solution, I added baking soda to water; to make an acidic solution, I added aspirin ...

Selecting the right satellite images and products can be challenging! In this blog, I am sharing my learning and experience of working with satellite images for image classification and visualization. The use of remote sensing satellite images to measure water qualities is a viable option to predict and control vector-borne diseases. Space agencies, such as NASA and ESA, provide open access to both acquired images and curated data/products for scientific research. Data is available both in the raw format as well as products (e.g. Top-of-Atmosphere (TOA) reflectance, ...

I currently have four traps in operational order. Two at one of my AOIs and two in backyard that were prototypes that I've left up because they seem to be performing admirably. I My traps have been up for about a week, the prototypes were deployed a day before the other two, and I haven't seen any mosquitos or mosquito larvae. I did take care to note that I used dog food in my trap, specifically the dry kibble variant instead of ones that come in chunks or are wet. I choose dog food over decomposed plant-based organic material because I noticed that the few times I've accidentally ...

Have you ever wondered why NASA has chosen to follow water ? NASA’s James Webb Space Telescope has captured the distinct signature of water outside our solar system. NASA's Artemis program is examining the presence of water on the Moon in advance of sending and establishing a sustainable human presence there.  The answer is simple - water is key to life as we know it, including on planet Earth. Only 2.5% of the water on Earth is fresh, and only a tiny fraction of that is available for use. NASA and other space agencies’ remote sensing satellites provide vital information to ...
