Insects that do not migrate from regions with the onset of colder temperatures must devise strategies to either tolerate or avoid lethal freezing of intracellular and extracellular body fluids. Insects that survive subfreezing temperatures are generally classified as freeze-avoidant or freeze-tolerant.
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Eggs of temperate zone mosquitoes are more tolerant of cold than the eggs of species indigenous to warmer regions. [69] [70] Many can tolerate subzero temperatures, while adults of some species can survive winter by sheltering in microhabitats such as buildings or hollow trees. [71]
Adult mosquitoes prefer temperate climates with mortality rates rising around 28°C (82.5°F) and can survive cold conditions by entering diapause in the egg stage. [ 6 ] [ 12 ] Life cycle
As the planet warms, mosquitoes are slowly migrating upward. The temperature range where malaria-carrying mosquitoes thrive is rising in elevation. Scientists now worry people living in areas once ...
Aedes aegypti (UK pronunciation: / ˈ iː d iː z /; US pronunciation: / ˈ eɪ d z / or / ˈ eɪ d iː z / from Greek αηδής: "hateful" and / eɪ ˈ dʒ ɪ p t i / from Latin, meaning "of Egypt"), the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents.
Eggs from strains in the temperate zones are more tolerant to the cold than ones from warmer regions. [33] [34] The species can even tolerate snow and temperatures under freezing. Adult tiger mosquitoes can survive throughout winter in suitable microhabitats. [35]
