United States: billions of periodical cicadas will emerge from the ground at the same time
Cairo: Hani Kamal El-Din
This sudden emergence of billions of cicadas is unlikely to harm the vegetation. Cicadas are not locusts, they do not attack leaves but they feed in small quantities on tree sap which does not harm them. This massive emergence of cicadas should, on the contrary, provide certain services to nature. Studies have shown that the holes that cicadas make when exiting then improve the infiltration of rainwater into the ground.
No need to use pesticides to get rid of them, entomologists remind in the American media. These cicadas do not sting or bite. After four to six weeks of living in the open air, they will die. There is therefore just a risk of being a little noisy, but we might as well take advantage of it because such an emergence will not happen again before 2037.
