Why can’t cockroaches be trampled on (why can’t cockroaches be trampled to death?)
Cockroaches have multiplied on the earth for hundreds of millions of years and are one of the most successful species in the world, mainly distributed in the tropics and subtropical regions. There are about 4,600 species of cockroaches in the world, and most of them live in the natural environment. There are only about 30 species whose habitats intersect with human living areas, and more than 10 of them are pests.
In China, there are more than 200 species of cockroaches, among which the German cockroach and the American cockroach are common indoor cockroaches. Cockroaches like warm and humid environments with plenty of food, so they can often be seen in kitchens and other rooms in southern China. This is a cockroach paradise.
Cockroach is listed as “four pests” because it can spread more than 40 A pathogen with super reproductive ability. Cockroaches are nocturnal animals and like to crawl around, so they are very responsive to people. Some of the small ones are fine, while the big ones are as big as a thumb, which is scary. Therefore, as long as you see it, you want to get rid of it quickly, one by one.
There is a saying that it is better not to step on cockroaches, because they will be trampled to death, but their eggs are likely to stick to the soles of shoes, and people do not wash them every day shoe. If it is not cleaned up in time, many small cockroaches will hatch indoors after a period of time; and there are many pathogens in the cockroaches. If you step on cockroaches rashly, these germs will be brought to various places in the room. Is it really?
A cockroach is a small insect that lays eggs. Different species of cockroaches have different numbers of eggs each time, ranging from a few to more than 50 eggs. These eggs will be stored in ootheca. In a warm and humid environment, the incubation period is about 20 days to 3 months. That little bean-shaped brown thing you see in the crevices of your bed or desk when you clean your room is a cockroach egg case. The ootheca is a capsule that is secreted by the female.
Different species of cockroaches lay eggs in different ways, which can be divided into three ways: outer ootheca, ventral ootheca and inner ootheca.
The outer egg case refers to placing the egg case in a relatively hidden and safe place, usually various cracks or depressions in the room. In this case, even if you trample the cockroach to death, as long as the conditions are right, the eggs will still hatch. Sometimes the cockroaches in the house are wiped out, but after a while a large group of small cockroaches appear again, this is the case. The American cockroach lays eggs in this way.
The egg-parent resource mesh sheath is placed on the abdomen. The cockroach that lays eggs in this way will drag the egg case to the abdomen. During development, the egg in the ootheca also receives water and nutrients from the mother. If they shed prematurely, the eggs cannot hatch successfully. This is how german cockroaches lay eggs.
Egg sheath embedded, belongs to ovoviviparous. The roach then stores the egg case in a nursery inside its body until the larvae hatch.The egg-laying method of sugarcane cockroaches belongs to this type.
Many times, in order to prevent cockroaches from stepping on the body with one foot and not being too lazy to clean the house, many people may just step on the cockroach lightly with their feet to make it immobile. In this case, if the female cockroach has an egg case, it is possible to survive and hatch. If the roach is crushed, the egg case may not survive.
As for the dead cockroaches, even if there are cockroach egg cases inside, everyone will quickly clean out the room together with the garbage, so don’t worry about being in the room incubation. In addition, the egg sheath is not so sticky, and the probability of sticking to the sole is very small. If you’re really worried, you can clean the soles of your shoes. Like the Periplaneta americana, which has an outer egg case, there are no cockroach eggs inside. So if you come across a cockroach, feel free to stomp on it. If you let go of one, especially a larger adult, after a while many smaller cockroaches will emerge.
As for stepping on cockroach shoes, you don’t have to worry about spreading pathogens, because although cockroaches have pathogens in their bodies, they are usually transmitted to humans through contact with food.
Cockroaches are so successful on earth because of their super ability to survive and reproduce.
Cockroach is a kind of incomplete metamorphosis creature, and its life will go through three stages: egg, larva and adult. Different types of cockroaches have different life spans, the short ones can only live for a few months, and the long ones can live for about 1 to 2 years. Generally, female cockroaches live longer than male cockroaches.
An adult fertilized female cockroach can produce dozens of eggs in its lifetime Sheath, the number of eggs in one egg sheath is generally more than 10. It only takes more than 20 days to hatch in a humid environment of 30 degrees. It is estimated that a female cockroach can produce tens of thousands of offspring a year. This fecundity is truly amazing.
Although there are male and female cockroaches, female cockroaches only need to mate once to lay eggs. Studies have shown that under extreme conditions, even in the absence of male cockroaches, certain species of female cockroaches can lay eggs that hatch without mating.
Cockroaches are omnivorous animals with a wide range of diets. They will eat anything when they are hungry, including the carcasses of their own kind. It can last for a week or two without eating or drinking, and even more than a month if there is water. In addition, cockroaches have strong drug resistance and radiation resistance.
Cockroaches not only have strong crawling ability, but also have wings, and some species have certain flying ability. When this family has nothing to eat, they will run to another house through sewers, doors and windows.
It can be seen that cockroaches are called cockroaches that cannot be killed, and they are indeed worthy of the name. It’s no surprise that indoor cockroaches are hard to get rid of.
Spiders, mice, toads, lizards, scorpions, centipedes, etc. They are the natural enemies of cockroaches. Although cockroaches have natural enemies, indoorOften there is no such animal. So if you want to kill cockroaches, except for slippers, you can only rely on pesticides. Of course, indoor hygiene should also be done well to avoid food residues as much as possible.
