A recent study published in the journal Nature reveals that the Aedes aegypti mosquito , known to be the main vector of diseases such as dengue, yellow fever, zika and chikungunya, has the ability to detect infrared radiation. This mechanism, similar to that used by rattlesnakes, allows this insect to precisely locate its human targets.
Led by Professor Craig Montell of the University of California
Santa Barbara, the study details the different turkey telegram data stages by which the Aedes aegypti mosquito detects its human hosts. The first stage is based on the detection of carbon dioxide (CO2) emitted by human breathing. This detection can be done from more than ten meters away and triggers an increase in the mosquito’s activity, making it more attentive to other signals emitted by the host.
At closer distances, about one to two meters, the mosquito is guided mainly by human body odors. However, in environments with air currents, this method of olfactory guidance can be inaccurate due to the mosquito’s poor visual acuity.
The researchers tested the hypothesis that the Aedes aegypti mosquito could also use infrared radiation to more precisely locate its target. The human
body naturally design an seo content strategy emits energy in the form of infrared radiation, which could be perceived by the mosquito. To test this hypothesis, the scientists conducted an
experiment with 80 female mosquitoes in a cage placed near two plates: one at room temperature (29.5 degrees Celsius) and the other heated to 34 degrees Celsius, the typical
temperature of v line data human skin. They also introduced a cloud of CO2 and diffused the smell of human sweat to simulate realistic conditions.
The results showed that the mosquito response was low when only
one of the cues (CO2, odor or infrared radiation) was present. HoweveThe researchers suggest that this ability may be present in other species of blood-sucking mosquitoes.
