Where Do Mosquitoes Sleep?
Several mosquito species are crepuscular feeders, which means they feed during the night. Some, such as the Asian Tiger mosquito, hunt for the next bite during the day. Others, such as the common mosquito, are diurnal. These are the most active at dusk. In these conditions, they are most likely to feed and rest in a dark or sheltered location.
Other insect systems have shown that sleep is associated with circadian rhythms and behavioral correlates. This suggests that sleep may be a critical component of the biology of some mosquito species. These sleep states are thought to influence mosquito biology, especially with regard to disease transmission.
Until now, few studies have looked into mosquito sleep. However, the question remains. It is important to examine the role of sleep in these mosquito species. It is a promising area for research, particularly because it can lead to new and more accurate models of disease transmission.
To study the role of sleep in mosquitoes, biologists at the University of Cincinnati and Virginia Tech developed protocols for their research. During a week-long experiment, the researchers observed sleeping mosquitoes.
They found that the mosquitoes preferred to rest in dark or sheltered locations. They were also less active when they were in their sleep-like state. The researchers suggest that these sleep states are distinct from the awake, active state.
They believe the sleep-like state may be influenced by host availability. When there is no host available, the putative sleep duration decreases, and the mosquito is more likely to be interested in blood feeding.
