Speaking of cockroaches, everyone should be familiar with it, it also has a breast name called Xiao Qiang, a nickname called Stealing Oil Po, but its scientific name is rarely known, called cockroach.
Cockroaches, scientific name cockroaches, belong to the insect class, orthoptera, cockroach family, has a history of 350 million years, is one of the most primitive winged insects in existence. For humans, cockroaches have a strong ability to transmit diseases and are the culprits of many infectious diseases. It can carry and spread a variety of pathogenic bacteria through the body surface and intestinal cavity, causing cholera, typhoid fever, paratyphoid fever, dysentery, anthrax, tuberculosis and other diseases; its excrement and shed epidermis will also carry allergens, making people rash, asthma and so on.
What are the types of cockroaches < h1 class="pgc-h-arrow-right" >? </h1>
There are three most common species in our lives: the German cockroach, the American cockroach and the Australian cockroach. Could it be that the little strong people around us are actually of foreign origin? Probably these three places are both famous and famous for cockroaches!
In contrast, the small strong head of German descent is the smallest, which is a great contrast with the tall and powerful image of Germans; American and Australian cockroaches are roughly equivalent, both are large. Ordinary people may find it difficult to distinguish between the three small strong, but in the eyes of professionals, the difference between them is still quite large. The German cockroach is small, small, and generally active in the kitchen; the two adult cockroaches are several times the size of the small cockroaches, and are more common in hot and humid sewers. Their physical characteristics and life habits are slightly different.
<h1 class= "pgc-h-arrow-right" > the habits and physiological characteristics of cockroaches</h1>
Cockroaches are generally afraid of light and dark, day and night, and it is not easy to find them during the day. No wonder many places, during the day to check, can not find the trace of cockroaches, think they are extinct; at night, do not know where they emerge from, stir up the wind, the scenery!
Cockroaches have a characteristic, bet that thousands of people do not understand, today to reveal a little to you. Sometimes, a single female cockroach can also reproduce! This may seem unreasonable, but it is true. Scientists don't say whether this is true for every female cockroach, but they are sure that some female cockroaches can mate only once in a lifetime, but can lay eggs multiple times. A female cockroach can produce a population of hundreds of thousands of cockroaches during its lifetime. This fecundity is terrifying!
Why are cockroaches called "undead little strong" in the jianghu? It's not that it really can't die, it's that it can't be destroyed, because it's too capable of life! Now you get the idea.
<h1 class="pgc-h-arrow-right" > cockroaches may not be extinguished, but they must be controllable</h1>
Cockroaches may not be extinguished. Today you have destroyed a pile, tomorrow it has again; the killing here is finished, the possibility of other places is coming again, in short, the enmity between man and cockroaches will never end!
However, the number and influence of cockroaches can be artificially controlled at a given time and space. How?
First, control its breeding grounds. Cockroaches are mostly born in dirty and chaotic places, after understanding their living habits, they use fast, accurate and fierce methods to continuously attack and kill the "one pot end", so that it is difficult to even sprout!
2. Control of their activities. At the initiative of the government, the "people's war" to kill cockroaches was launched, and everyone saw it and cursed it, and never slackened off.
Third, this is a new topic, but it is very important, and it is the guiding ideology of the cockroach eradication action. We humans can't blindly pursue some short-term goals, such as eliminating the harm of cockroaches, which can easily lead to the loss of one or the other. Perhaps, in some ways, cockroaches have their own unique irreplaceable effect on humans or the natural environment. Therefore, we should treat this problem rationally and scientifically from the perspective of ecological environment construction, which may be the ultimate way out!
