The reason which allows cockroaches to invade the world successfully

Cockroaches are an extremely successful, extremely successful insect on all continents except Antarctica. There are 4,600 species of cockroaches around the world with complicated social behaviors and practices, according to Popular Science.

German cockroaches, the most widely dispersed cockroach in the globe, is an indoor harmful item with persistent vitality. “They are basically a suitable species to invade,” Warren Booth, an urban insect, commented. This cockroach owns a long list of super powers. If a pair of cockroaches crawl into a new house, they can spread extremely quickly. A female cockroach can lay 40 eggs at a time and about 200-250 fruits throughout the life cycle.

Their closest relatives are that American cockroaches can go further. If a female cockroach wants to start a new family, it can do so without waiting for any male cockroach to appear. It can be virgin, meaning that young cockroaches can grow from unprocessed eggs.

According to Booth, harmful cockroaches can even regenerate the broken limb. “They do so with the inner tissue. They can lose the entire trachea, then regenerate,” Booth said. Finally, cockroaches can eat almost anything and survive only based on waste.

Faced with harmful insects capable of regenerating and reproducing so quickly, humans must use chemical weapons. The invention of DDT insecticides in the 1940s activated a “arms race” between chemicals more and more dangerous and the adaptive genome of cockroaches.

The use of indiscriminate insecticides for decades then leads to the destruction of useful populations such as honey bees, accumulating toxins inside wildlife with many impacts on health, thinning eggshell of birds, even increasing the risk of cancer in people exposed to chemicals. Within a few years, cockroaches with DDT resistance began to appear. Modern cockroach population is resistant to all insecticides born between the 1940s and 1990s. Booth explains that they can produce enzymes to detoxify and quickly decompose harmful chemicals.

Part of the problem lies on the huge scale of the cockroach community. While bees rely on a queen bee to reproduce, cockroaches can increase the number through thousands of breeding members simultaneously. This provides more opportunities for a sudden anti -drug gene appearance.

Despite being famous as a harmful species, cockroaches are also an important source of food in agriculture and hydroponic, used to manage waste in some Asian countries, even cosmetic production materials. Many species live in rain forests, accounting for 25% of biomass in forest trees. According to Booth, without cockroaches, rain forests will collapse because they are basic decomposition species.
