Are Cocks Roaches Dangerous?
Cockroach is a common name given to several species of insects in the order Hemiptera. They are among the most abundant insect groups found worldwide, with populations estimated at over one billion individuals. Although they have been known since ancient times, their importance in modern society has only recently become apparent; they were once considered vermin or pests until recent advances in biotechnology allowed them to be used as food additives and pharmaceuticals.
The term “roach” itself comes from the Old English word roca meaning “a small rodent.” However, it was not until 1854 that Charles Darwin published On the Origin of Species, which included a chapter titled “On Insect Life,” in which he discussed the existence of insects. Since then, numerous other scientists have confirmed Darwin’s findings.
Insects are not just useful for food but also serve many other functions such as medicine, pest control, and even energy production (such as photosynthesis). They are also very important to human life because they play a vital role in maintaining our environment and keeping us alive. Even the smallest members of this class have a crucial part to play; bacteria, for example, help break down organic matter so that the nutrients contained within it can be returned to the soil so that plants can use them to grow.
The most widespread species of insect are ants, which can be found in just about every terrestrial ecosystem and occupy almost every niche in the food chain. Ants first appeared in the Permian period and diversified greatly as the world’s climates changed, with over 12,000 species of ant currently known to science. The name ant is derived from the Latin word for ant, formica.
Cockroaches belong to the order Blattodea, which encompasses many species of omnivorous insects that are mostly nocturnal and prefer to live in groups. Despite their reputation as disease carriers, there is no evidence to suggest that they are more prone to disease than any other type of animal. These common misconceptions about them have led to the widespread introduction of pesticides and other dangerous chemicals into our environment with little regard for their effects on other species.
While most types of roaches prefer to dwell in the soil or among plant life, a few can be found living in trees, such as the safari or tree roach from the Philippines.
The diet of a roach mainly consists of anything organic that they can find, such as food waste or even dead animals. While the idea of eating other living creatures might seem disgusting to us, there are many animals such as lions that do exactly that and are still essential to our environment.
Despite their bad reputation, roaches have been shown to play a vital role in keeping our environment healthy. Perhaps if more humans could learn to live in peace with them, as the Native American tribes did, we could stop expending valuable resources killing them and instead focus on the real threats to our continued survival on this planet.
Cockroach Species of the Americas
The following is a list of all known species of roaches that can be found in the Americas region, including Central America and South America.
The American roach, or Periplaneta americana, is a large species of brown or dark-gray roach that is common throughout North and South America. It is the largest species of roach within the region and is also the most commonly found, especially in more urban or populated areas. The American roach has a body length of about 2 inches with long and slender legs that enable it to run quite fast when necessary (1).
The American roach is thought to be one of the cleanest types of roaches as it is very averse to coming into contact with filth or disease. It can often be found scavenging dumps or landfills for food and even eats the eggs of other, smaller species of insects and spiders (2).
American roaches are nocturnal and are often found hiding in cracks and crevices during the day. At night, they scavenge for food and can often be seen near street lights as the extra light attracts insects for them to feed on (2).
These roaches can often be found in basements, sewers, drains, damp areas or any other damp or wet areas where there is shelter from predators (3). The American roach has been known to climb up vertical surfaces and can even survive underwater for up to 24 hours, enabling it to hide from predators or hunt underwater prey (3).
American roaches produce a thick and sticky like substance from their bodies that can help prevent small particles of dust or dirt from reaching their internal organs. It is thought that this might be a defense mechanism against other roaches or predators that don’t finish the job when hunting them (1).
The German roach, or Blattella germanica, is a smaller species of light brown to dark brown or even black in color and is the most common type found in kitchens and bathrooms (4). It has a body length of about 1 inch and is a good flier, but not as agile or fast when compared to other species (4).
The German roach is quite a nomadic species that can often be found in large groups or colonies. They are common pest species and can often be found feeding on human and animal waste, garbage, decaying matter and any other organic matter (4).
They build silken webs around doors, windows, gaps and any other entry points in an effort to keep other roaches from invading their space.
