The percentage of the total number of mosquitoes that were attracted to the most attractive group. Concept introduction: Plasmodium is one among the genus of unicellular eukaryotes that are obligate parasites of vertebrates and the insects. They infect the humans and are responsible for most malarial infections. It is transmitted through the bite of female anopheles mosquito. The life cycle involves the mosquito and human as the host. When they ingest from the human blood, the malaria infected mosquito inoculates the sporozoites into the human host. The sporozoite infects the liver cells and matures into schizonts that rupture and release the merozoites.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Is it more beneficial for Neodermata to have one host or two hosts? Neodermatahas two classes: class Trematoda and class Monogenea. Class Trematoda has the subclass Digenea, which has organisms that live through at least two different hosts. An example of this is Fasciola hepatica, the sheep's liver fluke. Class Monogenea has organisms that only need to live through one host. Is it better to have a simple or complex life cycle? Which lives longer? Has more energy? Does more damage or good?

Choose an example of a host adaptation that may not look advantageous at first, but was determined to reduce parasite load. Explain the mechanism for why this came to be and why it was advantageous.

Even though genetically engineered mosquitoes might be developed that do not allow the reproduction of malaria protozoa, these mosquitoes would have little, if any, immediate effect on the spread of the disease. Why should this be so? What would have to happen for these mosquitoes to significantly affect the spread of malaria?
