New Mosquito Species Found in U.S. After Century of Study
10 Sep
Summary
- Aedes amateuri, a mosquito previously found only in Mexico, is now in the U.S.
- Researchers found the new species in Arizona's Sky Islands mountain areas.
- The mosquito feeds on humans and mammals, but disease-spreading potential is unknown.
A species of mosquito previously identified only in Mexico has now been detected in the United States for the first time. Researchers discovered Aedes amateuri in the Sky Islands region of southeastern Arizona.
This mosquito is known to feed on humans and other large mammals. However, scientists currently have limited information regarding its biology, including whether it can transmit diseases. The finding highlights the ongoing importance of mosquito monitoring, as new species are still being identified in the U.S. after extensive study.
The mosquito has so far only been found in specific mountain areas within Arizona, such as the Santa Rita, Dragoon, and Peloncillo mountains. While not yet detected in urban settings, researchers anticipate it may have spread to adjacent New Mexico due to similar environmental conditions.
Detection of Aedes amateuri is challenging due to its specialized habitat. Scientists typically find its larvae in temporary water pools formed after monsoon rains, meaning adult populations may be transient and dependent on precise rainfall patterns. Arizona already hosts over 40 mosquito species, with many active during the state's warmer, wetter months from March to October.
