The locust's love changes because of the noise

Male grasshoppers that live in noisy urban environments must increase the volume of the melodies they emit to "flirt" with their children.

In nature, grasshoppers have a unique pairing style thanks to the love songs that the males play to attract females. The male grasshopper brushed the serrated layer under the hind leg into the protruding part of the front wing. This sound lasts only 2 to 3 seconds, clear and slow at first, then quickly and gradually stronger, then like a murmur at the end.

Increasing the sound frequency in "chats" is the way
Male grasshoppers apply to deal with artificial noise.

A group of experts from Bielefeld University's Department of Evolutionary Biology in Germany captured 188 bow grasshoppers in both urban and rural areas to understand the effects of man-made sounds on end behavior. double of insects.

Scientists have paired several male grasshoppers with the same grasshopper in a laboratory and recorded the results after each transplant. The results showed that the sound frequency calls to partners that male grasshoppers in urban areas are much higher than those in rural areas.

'The level of noise increase can affect the pairing process of locusts in many different ways. It can block love songs to the ears of the children, make them unable to recognize the same males, or reduce the attention of the children to the love, " Ulrike Lampe, team leader , conclude.

This is the first study of the effects of artificial noise on an invertebrate species.
