Flies, a small insect that is annoying in daily life, have a special habit of rubbing their hands, which arouses people's curiosity. This habit may seem funny, but behind it lies the unique survival wisdom of flies.
The survival wisdom of flies is reflected in their behavior of rubbing their hands and feet frequently. This is not a simple crushing action, but a multifaceted effort to sustain the flies' lives.
Flies do not have noses, but taste food through the sensory organs on their feet. In order to guarantee the accuracy of this perception, flies must frequently rub the fluff to remove dirt residue in order to maintain taste sensitivity. This is essential for the survival of flies, as accurate taste judgment is directly related to their ability to discriminate about food.
Flies have hooked claws on their feet that are used to attach to surfaces. But if it is dirty, the adhesion will weaken, affecting the stability of the flight. To maintain this stability, flies need to clean their feet frequently to ensure that flying remains an important survival skill for them.
Hand rubbing is important not only when searching for food, but also in the courtship process of flies. Flies that rub their hands quickly release pheromones that make them more attractive, which is essential for the reproduction of offspring. This habit shows the ingenuity of the fly's survival strategy.
Although flies rub their hands with a clear purpose of survival, sometimes they accidentally rub their heads off in the process of rubbing. This is not accidental, but because the control center of the fly's head and body are not very connected, so the head is accidentally detached because the force is not noticed during the process of concentrating on rubbing the hands. Although the importance of the head to the fly cannot be overlooked, the body's ability to remain active for a period of time demonstrates the amazing physiological mechanism of the fly.
Even after losing their heads, flies display a peculiar "superpower" – they can still survive for a period of time. This is very different from vertebrates, and the key is that invertebrates such as flies have distributed nervous systems.
The brain of vertebrates is the center of the nervous system, and once the brain dies, the whole body functions are paralyzed. The nervous system of invertebrates such as flies is "decentralized", and the central nervous system, sympathetic nervous system, and peripheral nervous system are independent of each other. Even if the central nervous system in the head is damaged, the other two systems can continue to function and maintain basic vital activities.
Although flies can move through other parts of their bodies after losing their heads, they are unable to consume food after losing their heads because their feeding mouthparts are in their heads. As a result, headless flies will eventually starve to death because they can't eat. Although they have demonstrated "superpowers" for a while, they also have limits to their survival.
As one of the "four pests", the control of flies in the family is very important. Through a systematic and scientific approach, we can reduce the breeding of flies and other pests, and ensure the health and safety of individuals and families.
First of all, keep the living environment clean, regularly clean up the garbage, mop the floor, disinfect the tables, chairs and the ground to prevent flies from breeding in a dirty and messy environment.
Store your food properly to reduce the attraction of flies. Put perishable food in a crisper and minimize direct exposure to air. At the same time, clean the refrigerator regularly to avoid spoiled and unflavored food residues.
Install fine fly nets on doors and windows to effectively block the entry of flies and keep indoor air circulation.
Sticky insect boards are placed in corners where flies are frequented, and fly swatters are used to directly attack or repel flies, which is an effective means of control at home.
Clean the drains regularly to avoid becoming a breeding ground for flies and ensure smooth drainage both indoors and outdoors.
Try to use natural and pollution-free control methods, such as lemon, garlic, mint and other plant odors have a repellent effect on flies. These plants can be placed in various corners of the house, or fly repellent spray can be made.
If you have pets at home, clean up their excrement in time to prevent them from becoming a breeding ground for flies.
When all methods fail, be cautious about using professional pesticides. When using, it is necessary to pay attention to the toxicity and dosage of the product to avoid environmental pollution.
Flies are just one of the "four pests", the other three include mosquitoes, rats, and cockroaches, all of which pose a threat to human health. Mosquitoes are the transmitters of diseases, while rats and cockroaches carry a variety of pathogens and are prone to infectious diseases. Therefore, the prevention and control of these "four pests" needs to be comprehensively considered.
In daily life, it is necessary to prevent and control flies and other "four pests" in a scientific and rational way, and keep the living environment clean and hygienic. Careful use of chemical pesticides and more environmentally friendly controls ensure that our living spaces are fresh and pleasant and free from pests. In the struggle against these small creatures, we can better appreciate the importance of scientific prevention and control, and create a healthy living environment for ourselves and our families.
