Why don t mosquitoes bite in autumn?

Why is it autumn and mosquitoes are still biting people so badly? Many people have such doubts. Oregon State University, USA.

Ecologists William Bradshaw and Christina Helzapfi found that one of the reasons is that the autumn is getting warmer and the mosquitoes are delaying the start of hibernation.

Researchers began collecting winter data from animals in 1972. They conducted a statistical analysis of the winter time spent by mosquitoes for more than 20 years, and found that today's mosquitoes wait an average of nine more days than the 1972 mosquitoes before starting to hibernate before they start hibernating. Next, they analysed weather data over 20 years and found that mosquitoes began to hibernate later and later as average temperatures slowly increased in autumn.

Therefore, with global warming.

People not only have to deal with various climate disasters, but also have to allocate part of their energy to deal with mosquitoes.

Mosquitoes generally start in May and reach their peak in mid to late August. When the temperature drops to 10 degrees Celsius.

In the following cases, the remaining mosquitoes will stop reproducing and will enter hibernation without eating or moving. Many people think that mosquitoes only come in the summer and that they will die out in the fall. In fact, early autumn and mid-autumn are both active periods for mosquitoes.

When the weather is too hot, the vitality of mosquitoes will be weakened. The best temperature for mosquitoes to survive is between 28 and 30 degrees Celsius, and mosquitoes are more active on rainy days.

Female mosquitoes bite indoors, and they suck blood to provide more nutrients to their offspring when they lay eggs. Autumn is rainy and the temperatures are pleasant, creating more opportunities for mosquitoes to breed. Therefore, the autumn mosquito bites people more fiercely, sucks more blood, and the mosquito carries more germs, so there is a saying that the autumn mosquito is more poisonous than the summer mosquito.

However, the lifespan of mosquitoes is generally 1 to 4 weeks, and as the weather gradually cools, mosquitoes will gradually disappear in the half month after the Mid-Autumn Festival.

According to the World Health Organization.

Statistics, only in the Sahara Desert.

In sub-Africa, nearly 1 million people die each year from mosquito-borne falciparum malaria. We should do a better job of mosquito prevention for young children in autumn.

Because the weather is cold, mosquitoes can't stab their mouths.

It's cold, and I can't fly.

He's going to die, and he doesn't have the strength to bite!

Generally, there are no mosquitoes, because the weather is getting colder, if there is a heated place, there will be several mosquitoes.

The growth of mosquitoes: the life of mosquitoes goes through four stages: eggs, larvae, pupae and adults. Mosquitoes like to lay their eggs in clear water, such as small river water, rain puddles, ponds, ponds, rice paddies and mountain streams. In the warm season, the eggs hatch in about three days and begin to eat the tiny microorganisms and protozoa that grow in the water.

They lean against the two blowholes at the end of their bodies close to the surface of the water to absorb air turbulence. After molting, they finally stop eating, become less active and become pupae. After about two or three days, the pupae come to the surface of the water again, shed their skin and emerge as adults.

Male and female mating mostly in the early morning or evening, first male mosquitoes around the top of a low tree, eaves, windows or open areas in groups of flocks, female mosquitoes see the opportunity to join the team, in the flight quickly mate. Male mosquitoes only suck grass juice, and live with plum honey and do not suck blood. Female mosquitoes must suck blood (human or animal blood) eggs to mature after mating, so only female mosquitoes can transmit diseases.

Female mosquitoes can lay eggs once they suck blood, and they can lay eggs six to eight times in their lifetime, with 200 300 eggs each time, so the early elimination of one mosquito is equivalent to the elimination of hundreds, thousands. It is important to know the life history and breeding sites of mosquitoes, and we can apply this knowledge to fight mosquitoes. If there is no stagnant water, mosquitoes will not be able to grow and flush and store, and treating or modifying breeding sites is the root cause of mosquito prevention.

Mosquito larvae are the easiest to extinguish, because they must live in water, if they can fill up the lowland, drain the stagnant water, and often clean up the utensils that store water, there is nowhere to survive, and the mosquito control will definitely receive good results.

Mosquitoes are a type of insect that belongs to the family of mosquitoes under the order Diptera. Mosquitoes usually feed on blood, where female mosquitoes need proteins in the blood to develop eggs.

When the weather is cold, the ability of mosquitoes to move is limited. Mosquitoes are cold-blooded animals, and their body temperature is closely related to their surroundings. When the ambient temperature drops, the mosquito's metabolic rate decreases and its mobility decreases.

Mosquito bites require a certain level of mobility and sensitivity, so in cold weather, they tend to choose to reduce their activity or go into hibernation rather than looking for prey.

In addition, cold weather can also affect the development cycle of mosquitoes. Mosquitoes need the right temperature to develop, and low temperatures will prolong their development time, making it take longer for them to reach the adult stage. As a result, the number of mosquitoes also decreases during cold weather, reducing their exposure to humans.

To sum up, the reason why mosquitoes do not bite when it is cold is mainly due to their weakened mobility and prolonged development cycle. However, this does not mean that the cold season does not eliminate the risk of mosquito bites, as some mosquito species can adapt to the cold environment and continue to move the field. Therefore, it is still important to maintain proper mosquito protection measures to avoid the inconvenience and spread of disease caused by mosquito bites.

When it's cold, mosquitoes usually reduce their activity or go into hibernation, so they bite less. Here are some possible reasons:

1.Temperature Effects: Mosquitoes are cold-blooded animals, and their body temperature is affected by the ambient temperature. At lower temperatures, mosquitoes have a slower metabolism and less mobility, so they are less prone to biting.

2.Weather conditions: Cold weather is often accompanied by lower humidity and stronger winds, which are not conducive to mosquito breeding and activity. Mosquitoes need a moist environment to breed and find food, while dry and windy weather can reduce their activities.

3.Reduced host activity: In cold weather, people often reduce outdoor activities, especially at dusk and at night, which also reduces the chances of mosquito bites.

In addition, people may take mosquito protection measures, such as wearing long-sleeved clothing, using mosquito repellent, etc., which also reduces the chance of mosquito bites.

Just because mosquitoes are less active when it's cold doesn't mean they don't bite at all. In warm indoor environments or some special climatic conditions, mosquitoes can still appear and bite humans. Therefore, proper mosquito prevention measures should be taken in place in any season to reduce the risk of mosquito bites and disease transmission.
