When Does Mosquitoes Sleep?

Among insect species, the when does mosquitoes sleep question is still being researched. However, behavioral and physiological correlates have proven to be robust indicators of the sleep status of insects.

The majority of mosquito species rest during the day. They typically seek shady or sheltered areas to rest. They also use caves and holes in the ground to hide. They prefer dark places and are attracted to logs and rocks. The Asian Tiger mosquito, however, prefers to sleep outside.

Some mosquitoes are crepuscular feeders, and feed at dusk or dawn. These species have more active nights than do other mosquito species. They often use dense undergrowth and search for holes and caves. They also use a variety of chemical cues to detect people, including body odor, heat, and vibrations.

The duration of a mosquito’s sleep-like state can have a significant impact on their vectorial capacity. The length of their sleep-like duration depends on the availability of their hosts, and can be affected by urbanization. If there are no hosts, the mosquito’s sleep-like period may be longer.

It is possible that the duration of their sleep-like state is influenced by their ability to detect carbon dioxide from people’s lungs. It is also possible that the presence of an experimenter arouses them. This means that targeted studies must be conducted, and that experiments can’t be manipulated to avoid exposure to host cues.

While the answers to when does mosquitoes sleep are unclear, future research will be able to better determine whether sleep in these organisms can play a role in disease transmission.
