How Are Cockroaches Useful?
WouterCockroaches are important for the ecosystem, as they aid in the decomposition of organic matter. This process is beneficial in small amounts, but unchecked decay can destabilize a fragile ecosystem. Cockroaches also contribute to the nitrogen cycle, which is essential for growing plants.
Many cockroach species have medicinal properties. Researchers have isolated proteins from cockroaches that are effective against bacterial infections. One such protein, derived from cockroach brain tissue, killed 90 percent of a mixture of bacteria. Another study identified 11 peptides produced by cockroaches that have antimicrobial properties. Although researchers have not yet discovered the precise genetic sequence of these peptides or developed therapeutic drugs from them, the evidence is growing that cockroaches are useful for medical purposes.
Cockroaches have a complex, symbiotic relationship with a bacterium called Bacteroides, which lives inside their special cells. The bacterium is passed on to new generations of cockroaches by their mother. This bacteria is very useful to cockroaches, as it produces amino acids and vitamins that cockroaches need to survive.
Cockroaches also play important roles in science, food, and nature. As a pest in our homes, we often encounter these creatures.
