My experiment is to determine which type of water and bait is most attractive to mosquitos. I had 6 large buckets total, and I filled 3 of them with tap water and the other 3 with water from a pond. The pond contained algae which were included in the water sample. From there, I used fish food, sugar, and grass as my different baits, and I included 1 cupful of each bait in the water samples.  Hypothesis My hypothesis was that the pond water would have more mosquito larvae than the tap water because it contained bacteria, nutrients, and other organic material that could be ...

Purpose: The purpose of this experiment is to determine whether the size of trap openings affects mosquitos' preferences to oviposit. Basically, I wanted to study if mosquitos are attracted to a source more if it is more accessible with a wider opening, or if this didn't play a role in their egg-laying preferences.  Background Information: According to preliminary research, mosquitos are able to locate and pass through small gaps and holes such as holes in mosquito nets. They do this by first sensing the source (usually they detect human blood and carbon ...

Introduction: For my experiment I decided to test the effects of various commonly used compost materials on mosquito oviposition. Certain essential oils have been proven to either attract or repel mosquitoes, but often these extracts are difficult to come by especially in undeveloped/developing countries. Therefore, I wanted to find a natural repellant against mosquitoes that could easily be acquired. Another motivation was the fact that litter has become especially prevalent and is a major contributor to air pollution, so I wanted to determine if the rise of mosquitoes could be ...

A Novel investigation that aims to conclude what style of mosquito trap is most effective for reducing mosquito populations in relation with the cost of creating it. INTRODUCTION Ovillanta trap is a form of mosquito larvae trap created using discarded motor vehicle tires. When I was first introduced to the Ovillanta trap by Dr. Low, I became immediately set on building one myself. I didn't think it would be very difficult. After all, I have probably spent more time in my grandfather's basement workshop surrounded by power-saws and drills than anywhere else in the world. ...

Hello everyone! As my team's resident novice RF engineer, I figured that I'd write a brief article about something so integral to the A.M.E.A. Project! First, I must introduce some Amateur Radio linguistics and general knowledge that'd be useful in understanding this article! (Note: Originally this section was going to be a lot smaller but then I realized that I needed additional information in order to understand the basics I included!) >RF Stands for Radio Frequency. >Amplitude can be roughly defined as Signal Strength. >According to Wikipedia, Modulation is the ...

For my experiment, I am testing whether different types of baits would have different impacts on mosquito larvae breeding grounds. Introduction:  Mosquitoes are the deadliest animal on the planet. According to the World Health Organization, mosquitoes are responsible for the deaths of over 1 million people each year, most of which are caused by the spread of diseases, such as malaria. To help slow this trend, it is important for citizens like me to identify any potential mosquito habitats, as well as note any preferences within these habitats. In my experiment, I created ...

Purpose The purpose of this experiment is to determine the prevalence of two characteristics of containers in attracting more mosquitos. I wanted to measure if mosquitos prefer to lay their eggs in locations with more shade as well as how the color of the trap, dark or clear, can also impact this preference. Methods Since Aedes mosquitos, which are the most common type of mosquitos in San Diego County, tend to prefer containers with larger openings, I used such dishes to create my traps. Out of the three traps, I use a fully clear container for one and black containers for ...

Purpose: The purpose of this experiment is to determine the prevalence of each container’s exposure to sunlight in attracting more mosquitos. My intent was to measure the difference in the preferences of female mosquitoes to lay their eggs in locations with more or less shade.  Methods: After some research, I was able to deduce that the most common mosquitoes in North Georgia (specifically near Johns Creek) are Aedes and Culex, with some Anopheles (since they are somewhat prevalent throughout North America). Since I was limited to what I had at home, I went on a search ...

Introduction:  In my trap experiment, I decided to test the attractiveness of different bait types to pregnant female mosquitos. I was interested to discover what conditions drew in mosquitos the most.  Experimental Design:  I constructed 4 mosquito traps using plastic tupperware containers and filled them each with about 400ml of tap water. I then introduced a different bait type into the water of each of the traps. The first trap contained fermented grass clippings (about two handfuls give or take). The second trap contained a cup of white sugar and two ...

Purpose: The purpose of this experiment is to determine the type of bait and the container size that attracts the greatest number of mosquitos. I hoped to understand whether the amount of water and the bait in the water made a difference in the oviposition of female mosquitos. Setup: I used 6 different buckets of 3 different sizes and filled them with two types of bait- initially sugar water and water with grass. I made sure to fill up the buckets of three different sizes almost all the way with the largest bucket containing 5 quarts, the second largest bucket containing 2 ...

My experiment aims to find the effects of saltwater concentration on mosquito breeding.  WEEK ONE- June 13-18, 2022 Hypothesis- Mosquitos are more likely to breed in water with the least amount of salt. All the traps were set up in open Tupperware containers containing- 2.5 cups of tap water, 1 tablespoon of dog kibble, and either 0, 1, or 3 teaspoons of water, depending on which container. (I set up 2 control containers with no water in hopes to find mosquitos easier) WEEK 2- June 19-25, 2022 By this point, no mosquito larvae or eggs have appeared, ...

I’m located in Reno, Nevada. Reno’s climate is semiarid and Nevada is the driest state in the US. Additionally, Reno’s daily temperatures vary significantly: June’s average temperature high is 29 degrees celsius and its low is 10 degrees Celsius, similarly July’s average temperature high is 34 degrees and its low is 13 degrees celsius. In contrast, mosquitoes tend to breed best at around 29 degrees celsius and there are significant drop-offs in breeding as temperatures increase or decrease from 29 degrees. Furthermore, as a result of low vegetation in its semi-arid climate, Reno has very ...

I decided to have two controls for my experiment: plain water and sugar water. Since I am testing how mosquitoes react to flowers; specifically, the number of eggs I collect, I wanted to get more variant data by having plain water and sugar water. After the first week of my experiment, I saw that many ants infested the sugar water (as anticipated), however, I found more mosquito larvae in the traps that had both sugar and flowers. This concluded that either the mosquitoes were attracted to the scent of the flowers or the appearance. Living in New York City, there aren't many ...

For 4 weeks this summer, much like other Earth Explorer interns, I built a few mosquito traps and set them out near my home within my AOI. I’m located in sunny Plano, Texas, near a creek. To set up my traps, I first bought 4 large, 2 Liter soda bottles, drank a small bit, and emptied the rest out. I know we shouldn’t eat in the lab, but let’s just say the experiment started after the bottles were emptied. Then, I cut them in the middle and sanded the top halves near their mouths to make them a bit rougher. I got some net from a loofah and tied it to the mouths, then inverted the top so it ...

For my experiment, I decided to test the effect of sunlight and different colored traps on number of mosquito larvae. I started my experiment by gathering six white buckets. I then painted two of them red and two of them blue. I also covered each bucket with a sealant.  After the buckets were prepared, I placed a white, red and blue bucket directly in the sunlight. The remaining three buckets were placed in the shade, under a tree. Then, I filled each bucket with 3 liters of water and 100 grams of weeds. A wooden stick was also placed in each bucket and used to stir the ...

Introduction To follow along with NASA GLOBE’s mission to encourage public involvement in mosquito observation research, I decided to conduct a small experiment to determine preferred mosquito habitats. I’m writing this blog about my experience to encourage people to become citizen scientists as well and take part in the GLOBE Observer App’s mission [1]! Hypothesis Since mosquitos most commonly breed in swamps or marshes and are said to thrive in water that is fairly shallow, filled with organic matter, and nutrient-rich [2] [3], I hypothesize that mosquitos will be most ...

Introduction California is home to 53 mosquito species, including many that serve as vectors for diseases like West Nile, Malaria, and Dengue. In my county of California, Santa Clara, mosquitoes from the genus Culex and Aedes are most common. For mosquitos to keep their population flourishing, female mosquitos lay eggs in stagnant containers of water. These eggs then go through the mosquito lifecycle to reach maturity and reproduce. Purpose The purpose of this experiment is to determine how important stagnant water is to female mosquitos as they choose a location to lay ...

Purpose: My experiment aims to test whether: 1) Ovitraps or Safe Bottle Traps attract more mosquitoes   2) CO2 traps or CO2 under light at night attract more mosquitoes  Background: Studies have shown that mosquitoes can detect carbon dioxide and may move towards the area with an increase in carbon dioxide. In fact, pregnant women are a feast for mosquitoes! This is due to an increase in body heat and more significant amounts of carbon dioxide. Additionally, during the day mosquitoes avoid light and prefer shady areas. However, without sunlight, mosquitoes ...

My experiment is testing the effect various types of bait have Mosquito Habitation. My research consists of three five gallon buckets, all filled with equal amounts of water and placed under shade. Each of my buckets has a different type of bait (dirt, leaves, and wood chips). Each week I take out any larvae I see and refill the traps to the 9 inch mark (to keep the water level constant each week). I do not refill the bait. Each week I take a sample of each trap, collecting all the larvae I can see and count the medium/large larvae. Week 2: The trap with dirt had about 250 medium/large ...
