LIn The Man with the Golden Arm, published in 1949 and winning the National Book Award, Eglin made a rare mistake when, in his explicit depiction, cockroach blood, a dark liquid, was used as a Disgusting means of begging for alcohol. But in fact, the blood that flows through the cockroach’s whole body is a colorless transparent liquid. When its hard shell (that is, the exoskeleton) is pierced or crushed, it will spray out a liquid that looks like pus or smegma. Off-white substance. Of course, this bridge did not appear in the film directed by Otto Preminger, Frank. In the film adaptation starring Frank Sinatra.

This yellowish off-white substance is actually fat, which contains the organs, nerves and circulatory system of the cockroach. This thick layer of paste is located between the hard outer shell and the soft internal organs. It is called the fat body. Most of the metabolism takes place here; nitrogen and other nutrients are also stored here to sustain life in times of food scarcity.

The most common German cockroach (Blattella germanica) in the United States, which is the species we most often see in the kitchen, can survive for forty-five days without food as long as it has water; They can still live for more than two weeks. Other cockroaches live longer, notably the second most common species, the American cockroach (P. americana). As long as there is water, it can survive for 90 days; the American cockroach in the laboratory can live for 40 days without food or drink. Regardless of the species of cockroach, females survived longer than males without eating or drinking.

Cockroaches are natural survivalists. Although there are not many insects with strong survival ability, as far as we know, cockroaches are the oldest existing insects on the earth, which is indeed a very successful evolutionary design. Cockroaches have six legs like other insects, and the composition of the shell is chitin (also known as chitin); the head is always drooping under the carapace, and a pair of antennae protrude from the front. Viewed from the side, the cockroach looks like Always keep your head down. Its sleek exoskeleton and body shape allow it to squeeze into extremely tight spaces.

Survival Rule 1: Only by not being picky eaters can you live a long time

It can ingest nutrients from a variety of substances. Wild cockroaches eat a wide variety of foods, including plant debris, fungi, wood, animal dung, and eat almost anything. There are plenty of animals that are classified as omnivorous (eats everything), but very few live up to their name like cockroaches. Cockroaches living around humans eat whatever humans eat (except cucumbers, which I heard cockroaches hate). Cockroaches are happy to eat many things that humans would rather starve to death than eat, such as glue, feces, hair, leaf decay, paper, leather, banana peels, other cockroaches, humans (both dead and alive), and acid Warm beer (it is said to be a favorite of cockroaches).

Cockroaches appeared 150 million years earlier than dinosaurs and 300 million years earlier than humans. The earliest cockroach fossils can be traced back to the Carboniferous period of 325 million years BC. Every insect fossil left in that period Both represent the extinction of a species, with the exception of the cockroach. Fossil cockroaches dug up from a coal seam in Illinois look almost identical to cockroaches that live on the same soil today. The Carboniferous period of cockroaches was so numerous that it is sometimes called the Age of the Cockroach; cockroaches are still numerous today. Over the past two centuries, more than 5,000 species of cockroaches have been discovered and named. Scientists believe that there are about 5,000 species of cockroaches that have not yet been discovered. Cockroaches belong to the order Blattaria, a word derived from the Greek blattae, what the ancient Greeks called household pests.

The closest insect relatives of cockroaches are termites and mantises such as praying mantises. Both of these insects (as well as crickets and grasshoppers) have no teeth like cockroaches, but use their mouthparts to tear, tear, grind, and grind; the broad forewings are seldom used for flight, because they hardly fly. In the past these several insects were classified in the order Orthoptera, but then cockroaches got their own classification.

There are five families under the order Blattata, and there are about 10,000 species under it. In our usual living space, we only see a few species of cockroaches (less than a hundred); but as insects that prefer hot and humid, the tropical jungle may be the favorite environment for cockroaches. In 1983, a scientist set up only six traps in the jungle of Panama and captured 164 different cockroaches.

In any case, cockroaches are not restricted to a particular habitat, and can live in a variety of places, including under a woodpile in Alaska, in the canopy of a tropical jungle in Costa Rica, in a water-collecting forest in the Trinidad rainforest. Bromeliads, burrows in Australia, 2,000-meter mountains in Central Asia, swamps in Argentina, caves in Borneo, and bushes in the arid zone of Kenya. No matter where they live, cockroaches can spread and spread. But of the thousands of different species of cockroaches, most don’t interact with humans. If the Creator really exists, it can only be said that He especially favors cockroaches, because the structure of cockroaches is the world’s leading one, and cockroaches are undoubtedly the ultimate manifestation of biological evolution.

Therefore, humans can learn far more from cockroaches than cockroaches can learn from humans. This statement is not empty, because humans continue to spend a lot of time and money studying cockroaches. Every aspect of the physiology and behavior of cockroaches has relevant scientific research, and the number of documents is astonishing. As early as the nineteenth century, there were researches and discussions on the reproductive mechanism of cockroaches. Although cockroaches and humans are obviously quite different, cockroaches are considered an excellent model animal for neurobiology.

It is generally believed that cockroaches act entirely on instinct and are simple, sentient machines, especially suitable for biological research. Biology students love to dissect the American cockroach because of its size and abundance. “We can reasonably speculate that among the insects dismembered on the experimental table, the largest number is the cockroach; the number of mouthparts of the cockroaches observed under the microscope also far exceeds that of other insects.” Cornwell (PB Cornwell) in his So wrote in the 1968 book “THE COCKRAOCH”.

Survival Rule 3: Dodging the bullets of pesticides

Of course, there are not a few PhDs who earn a good salary by studying cockroaches day after day. By the 1970s, most cockroach research had to do with biology—how their bodies work, how they reproduce, and how they are classified. After the 1970s, research on the social and living behavior of cockroaches increased rapidly. Most of these research funds came from chemical companies that manufacture and sell insecticides. Their products disrupt cockroach behavior, control and/or eliminate cockroaches . Since bed bugs have not been seen for fifty years or so, cockroaches are the most annoying household pests in many developed countries.

Therefore, in addition to scientists, there is another group of professionals who make a lot of money from cockroaches: pest control companies. Pest control can make a lot of money every year, especially killing cockroaches. According to the United States Department of Agriculture, the annual cost of eradicating cockroaches, ants, mice and termites is about $4 billion. According to a recent study, the cost of eradicating cockroaches is approximately $240 million.

The eighteenth-century Swedish naturalist Karl. The scientific name given to cockroaches by Carolus Linnaeus does not accurately reflect where they originated. For example, in Eglin’s novel, the cockroach that crawled on the bar of the widow Widzyric was very likely a German cockroach; it is believed that the German cockroach first followed the Phoenicians across the Mediterranean from Africa, and then Spread to Russia, Europe, and finally to America. When most North American city residents turn on the lights at night, they see cockroaches running around. They should be German cockroaches, and they are also the most important parents of the pest control companies. These smaller brown cockroaches are mostly found in kitchens and bathrooms in apartments or bungalows.

Of the five common household cockroach species in the United States, the German cockroach is one (along with sixty-four species that live farther from people and may never be seen in their lifetimes) and is the most common. The wings of German cockroaches are structures left over from their ancestors, and because they have degenerated, they cannot fly. Most cockroaches have wings, but many are ostentatious. Still, the second-most common cockroach in the United States makes an occasional flight, the aforementioned American cockroach; some euphemistically call it a “water bug.”

Most people call them American cockroaches, but in fact they did not originate in America, but came from Africa on slave ships.

The American cockroach is dark brown, much larger than the German cockroach, and can reach a length of five centimeters. It is more common in the southern and subtropical regions of the United States. But American cockroaches are so adaptable that a patient observer near the boiler in the basement of any building in New York City has a chance of seeing them. They like to live in damp and dark places such as sewers and basements.
