COCKROACH DNA GIVES CLUES TO WHY THEY’RE SO STRONG AND PERHAPS HOW TO BETTER KILL THEM
The following is an excerpt from DANA DOVEY | March 22, 2018 | newsweek.com |
Cockroaches are extremely difficult to kill and constantly evolve ways to resist our attempts to control their populations. A new study has sequenced the DNA of roaches, revealing exactly what makes them so resilient and perhaps giving insight into how they can be killed.
The study, published in Nature Communications, specifically looked at the genome of the Periplaneta americana, also known as the American cockroach. The analysis revealed that cockroach DNA is even more fascinating than scientists previously knew.
For example, cockroaches are known for their ability to find food in even the most difficult environments. This is part of the reason they are able to thrive so well in urban areas, Smithsonian magazine reported. The report revealed that this ability to thrive in extreme environments may be due to the roaches’ high number of genes that code for chemical receptors. The bugs have over 1,000 of these genes, including 154 genes dedicated to smelling and 522 dedicated to tasting. This may explain their ability to get around and find food in even the most difficult environments, the study suggests.
