High School Biology Mosquito Review TEMPLATE

Female mosquitoes can track down their blood meal in a variety of ways, olfaction or "smell" being the overall reason that they can find you.

However that are still studies being conducted to see if blood types contribute to mosquitoes attraction towards humans and other animals.

In the graph provided, scientists determined that when mosquitoes are fed a specific blood type, they produce varying numbers of offspring.

Using the graph provided, can you conclude that mosquitoes in the wild will hunt for specific blood types?

(CLICK ON IMAGE TO ENLARGE)

• No, more information and experiments are needed since these mosquitoes in the study were fed blood instead of hunting for it.

• Yes, mosquitoes will always be more attracted to humans in B blood type.

• Yes, mosquitoes are mostly attracted to O blood types

• Yes, mosquitoes prefer at least two of the four possible blood types

Of the 6 common diseases vectored by the female mosquito, which of the disease(s) below is considered a living organism (biotic)?

• Malaria Protozoa

• Yellow Fever Virus

• West Nile Virus

• Zika Virus

• Dengue Virus

Malaria is the deadliest mosquito borne disease — common in sub-Saharan Africa, where it causes more than 400,000 deaths a year, the majority of whom are children under five.

Symptoms are chills, fever, and sweating, usually occurring a few weeks after being bitten.

It is caused by a single celled organism containing a nucleus, mitochondria, and other membrane bound organelles.

What kind of cell is this parasite?

•

The Navy Entomology Center of Excellence is located in Jacksonville, FL and is responsible for monitoring outbreaks of arboviruses (viruses spread by insects) across the globe.

The 3 mosquitoes that are most identified as problematic in regards to human public health are the Anopheles, Aedes, and Culex.

Why is it important to monitor for insects that carry diseases communicable to humans? (SELECT ALL THAT APPLY)

• It provides insight to which types of diseases are carried by specific species of mosquitoes

• It allows us to predict and prevent possible outbreaks

• It allows scientists to develop new breeds of genetically engineered mosquitoes that feed only on plants

• It helps us see trends in disease outbreaks throughout the world so that we connect environmental factors that influence mosquito breeding (temperature, weather, seasons, etc.)

A mosquito scientist is having a hard time identifying physical characteristics of a mosquito and needs to increase the magnification of her microscope. She typically uses light as a main source of observation, but the image is just too blurry.

She needs to use a microscope that provides higher magnification and resolution (1000x more detailed than light microscopy), and can also scan the surface of the mosquitoes foot structures. The image provided is what she sees as she looks through the microscope.

Question: What type of microscope would she be using, given the image provided?

• Scanning Electron Microscope (SEM)

• Transmission Electron Microscope (TEM)

• Dissection Microscope (Stereo Dissection Microscope)

• Compound Light Microscope

In the Bacillus sphaericus Bioassay, what was the independent variable?

• The different concentration in each container

• The number of dead larvae in each container

• The concentration that killed 90% of the larvae in the container

• There was no independent variable

In the Bacillus sphaericus Bioassay, what was the dependent variable?

(The dependent variable is what you were looking for in the experiment)

• The different concentration in each container

• The number of dead larvae in each container

• The LC90

• There was no independent variable

In the Bioassay, we set up one of the containers to have no pesticide, while the rest of the containers had a specified concentration of pesticide. 10 larvae were placed in all containers and after 24-48 hours we assessed the effects of the pesticide on the larvae. We were looking for the concentration that killed 90% of the larvae in that container.

What was the purpose of having one container without any pesticide?

• This allows us to see the health of the larvae without being exposed to any pesticide and gives us something to compare the other concentrations to

• This was to preserve at least 10 larvae at the end of the experiment

• This was an accident and should not have been done.

• If you find that none of the larvae are dead in the container without pesticide, then you must redo the experiment because your results are false
