PRAZZER- mosquitoes urinate when sucking

Blood-sucking insects bleak mosquitoes did have a strange behavior when sucking blood. As is known in advance by experts, they pee first. And, unexpectedly, they also issued a pre-urine liquid form of blood!


Such behavior makes the scientists puzzled. Claudio R Lazzari, entomologist of François Rabelais University in Tours, France, as quoted by the New York Times, saying, "Blood is something very precious. Release at high risk. "

Recent research conducted Lazzari and published in the journal Current Biology reveals that pre-discharge urine aims to lower the body temperature at mealtime, which can reach 40 degrees Celsius.

To get the conclusion that, Lazzari studied mosquito species Anopheles stephensi. At dinner, the liquid urine and urine pre-mosquito was issued through the anus. Sometimes, fluid hangs like dew which will trickle before it crashed.

According Lazzari, while urine and urine pre-released, the liquid evaporates and cools the body temperature up to 3 degrees Celsius. This mechanism is one of the greatness of insects in controlling body temperature.

Mosquitoes are not the only insect that uses its own food to regulate body temperature. Bees for example, throw a little nectar he eats to keep the head cool while still flying.
