What is the relationship between mosquitoes and people? What is the relationship between mosquitoes

When a female mosquito bites, it feeds on human blood. Is the relationship between female mosquitoes and humans parasitic or predatory? To get the answer to this question, it is necessary to first clarify the difference between parasitism and predation.

This is how parasitism and predation are explained in the compulsory textbook "Biology" of the People's Education Society. Parasitism: A phenomenon in which one life resides in the body or surface of another organism, from which nutrients are obtained to sustain life, this phenomenon is called parasitism.

Predation: The phenomenon in which one organism feeds on another. From this explanation alone, it is difficult to determine whether the relationship between female mosquitoes and humans is parasitic or predatory.

The author believes that in order to determine whether this interspecific relationship is parasitism or predation, it can be based on the following three differences.

Parasitism 1One organism tends to live in or on the surface of another organism for life or at some point in its life.

2.One organism often obtains nutrients and sap from another.

3.One organism tends not to kill another.

Predation 1One organism only stays on the surface of another organism for a short period of time.

2.One organism tends to acquire all or part of the organs of another organism.

3.One organism tends to kill another.

The above three judgment bases are mainly based on point 1, but each point is not the only basis for judgment, and should be looked at together.

Then, the relationship between female mosquitoes and humans has the characteristics of predation 1, parasitism 2 and parasitism 3, and does not have the characteristics of parasitism 1.

Leeches suck human blood, have the characteristics of predation 1, parasitism 2 and parasitism 3, and do not have the characteristics of parasitism 1, which should be judged based on the first point and should be predation.

Female mosquitoes bite plants, with the characteristics of predation 1, parasitism 2 and parasitism 3, and do not have the characteristics of parasitism 1, which should be judged based on the first point and should be predation.

Aphids and plants, aphids to"Plant lice"It is famous, gathers on the stems of certain plants to live, and feeds on the sap of the plant. They insert their mouthparts into the plant and then stay on the plant all the time, and if they can stay undisturbed all the time, they will stay in the place where they were born for the rest of their lives. But for most aphids, it is impossible to live undisturbed, and they are a favorite food for many predators and parasitic organisms.

The relationship between aphids and plants has the characteristics of parasitism 1, parasitism 2 and parasitism 3, so it is parasitic.

Parasitics, such as aphids and plants, can also be seen as parasitic.

<> the relationship between mosquitoes and humans is predation. Because mosquitoes live by sucking human blood, predation relationships refer to the interspecific relationships in which one organism feeds on another. The former is called a predator, and the latter is a ** eater. For example, rabbits and grasses, wolves and rabbits, etc., are all predators.

Under normal circumstances, the predator is a large individual, the ** eater is a small individual, and the large eats the small. The result of predation, on the one hand, can directly affect the population of the first eater, and on the other hand, it also affects the population change of the predator itself, and the relationship between the two is very complex. Predation is also an adversarial interrelationship between species.

The predation relationship is generally manifested as an asynchronous change of "the first to increase and the first to decrease, and the second to increase and then to decrease", that is, "one eliminates the other, and the other grows". The first to increase and then decrease is the ** eater, and the second to increase and then decrease is the predator. Interspecific struggles in predatory and competing genera, interspecific mutual assistance in symbiotic genera, intraspecific struggles and intraspecific mutual assistance in the relationship between organisms of the same species.

Symbiosis is when two organisms live together in one, dependent on each other and mutually beneficial: if separated, either of them or one of them can not survive independently, and it can be seen that the number of individuals of two organisms that are symbiotic should change synchronously over time.

Predation is a phenomenon in which an organism feeds on another organism, and the population relationship between the two organisms is one and the other, and there are regulatory and inhibitory effects between each other, so as to maintain the relative stability of the two populations.

<> "The Relationship Between Man and Mosquitoes."

Buzz in your ear gently branch to tell you, sprinkle the waves, hey, ah, ah, slippers warning! Didn't Mo Wu say that mosquitoes covet my beauty and think my type O blood is too fragrant, so they always stare at me and bite? Don't go any closer to the hood pure me, dead mosquitoes!

Dead water, non-flowing buckets, hydroponic plants, etc., are the best places for mosquitoes to breed. Mosquitoes grow quite fast, most of them survive for a week, and early detection can kill mosquitoes in their cradles.

1. Control the number of other species, the reason why humans hate mosquitoes very much is that they are often bitten. But bites and sucking blood are indeed their most important role in nature. Due to the greedy bite of mosquitoes sucking blood, while injecting toxins wax back to swimming.

Mosquitoes become vectors of disease. In this way, mosquitoes have been declining in this way for millions of years, including humans. The most recent Ebola virus, which was transmitted by mosquitoes, has led to the depopulation of Africa.

Without mosquitoes, many diseases would be completely slowed down or stopped, and animal populations would increase accordingly. Overabundance of species in nature often leads to starvation and death, as well as damage to the environment. All mosquito species reduction is to protect the planet.

2. It is a kind of food**, mosquitoes are, from fish to birds and other creatures, reliable and necessary food**. Many organisms, like fish and birds, evolved with mosquitoes and evolved hunting techniques specifically designed to find and capture mosquitoes. If those mosquitoes are no longer there, these animals will have no primary food**, so their populations may decline, or go extinct.

In other harsh environments, mosquitoes are food for migrating animals and birds**. When birds migrate from south to north during the summer months, they rely on large numbers of mosquitoes for food. Many birds migrated and could not find food other than mosquitoes.

First-time migrating birds can rely on mosquitoes to stay alive. Without them, the migration process can be difficult to complete, and the number of birds that survive the migration may decline dramatically.

3. Environmental filter, mosquito as a natural filter is of great significance to the environment. Mosquito larvae grow in the water and feed on detritus, which float and clog the surface of the water, while mosquito larvae prevent debris from clogging the surface of the water and the plants in the water do not die due to lack of nitrogen and oxygen. If there are no mosquitoes to consume the waste, many plants and ecosystems may also disappear, so mosquitoes are a kind of environmental filter for activity.

4. Help pollinate plants, male mosquitoes do not feed on blood. Instead, he survives on the sugars present in the nectar of the plant. When male mosquitoes feed, they help pollinate plants of the same kind.

In subarctic climates such as northern Canada and Russia, mosquitoes play a major role in plant pollination. In other regions, mosquitoes are no worse than bees and butterflies when it comes to pollination. While the results of mosquito control may not be felt in all regions, they can be affected in those subarctic regions where plants rely on them for pollination.
