Scientists have discovered a change in the behavior of cockroaches in sex

As a result of the use of poison, cockroaches became quicker in sex and fell out of love with sugar

Due to the use of glucose-based poisons, domestic cockroaches fell out of love with sugar, changed their mating behavior and began to have sex faster.

Previously, males of red cockroaches or Prusaks presented them with a “wedding gift” to attract females. They secreted an attractive mixture of fats, proteins and malt sugar under their wings. While the female was eating it, the male copulated with her for about 90 minutes.

But about 30 years ago scientists noticedthat cockroaches began to have an aversion to glucose. This mutation helps them avoid poisoning, and it also made it difficult for them to reproduce. As soon as the boyfriend’s saliva was converted into maltose, the females ran away. Males did not have time to copulate with them.

Scientists from North Carolina State University have found that cockroaches have acquired a new mutation that allows them to produce not maltose, but the more complex trisaccharide maltotriose. This substance attracts females and breaks down much longer than maltose.

Males also started mating twice as fast, 2.2 seconds after the female starts eating the gift. This discovery, according to the researchers, will allow the development of more effective means to combat cockroaches of a new mutation.
