Do you also have cockroach phobia? The summer arrives, and with it, many insects also appear to take a vacation, for example, cockroaches. Although they can appear in our house at any time, the heat and humidity favor that they appear with more intensity.
You may get up and see one of them in your kitchen and be most uncomfortable, not only because of their appearance but also because they can transmit diseases such as gastroenteritis or dysentery due to the bacteria they have in saliva, feces or other parts of the body.
Now, in addition, thanks to a new study we have just discovered that they may be almost immortal. How is it possible?
Resistant to certain chemicals
A recent study published in the scientific journal Nature prepared by experts from Purdue University in Indiana (USA) reveals that cockroaches are becoming resistant to chemical insecticides or pesticides.
Specifically, the experiment has been conducted with a common species, the German cockroach, known as ‘Germanic Blattella’ in the scientific world. The entomologists who conducted the research were responsible for assessing the resistance developed by German cockroaches in urban areas of Illinois and Indiana, exposing them to different pesticides over a period of six months.
Specifically, one of one. After the experiment, the team warned that the most effective way to control a colony of these insects was by using three different types of insecticides since in the other groups analyzed, cockroaches created resistance to chemicals.
In fact, they demonstrated that later generations that were born did so by being resistant to the insecticides used. «The resistance increased four or six t the groups of cockroaches were exposed to three different chemical pesticides; another to two; and the third and last, only times in a single generation. We had no idea that something like this could happen so quickly, ”said one of the leaders of the experiment, Michael Scharf.
Therefore, this new study demonstrates that to combat pests it is necessary to use methods that combine different chemicals, otherwise, it will be almost impossible.
