Since the transition from water to land, maintaining water balance has been a key challenge
for terrestrial arthropods. We explore factors that allow terrestrial arthropods to survive within …

Trehalose is a major circulatory sugar in the haemolymph of insects. It provides instant
energy and protection against stress. Trehalose metabolism is associated with insect growth …

Most multicellular organisms are freeze sensitive, but the ability to survive freezing of the
extracellular fluids evolved in several vertebrate ectotherms, some plants, and many insects …

Highlights•Insect mitochondria may be crucial for determining organismal cold
tolerance.•Insects can sustain rates of mitochondrial oxidation and coupling at low …

Ticks are blood-feeding ectoparasites but spend most of their life off-host where they may
have to tolerate low winter temperatures. Rapid cold hardening (RCH) is a process …

Freeze tolerance, the ability of an organism to survive internal ice formation, is a striking
survival strategy employed by some ectotherms living in cold environments. However, the …

The accumulation of trehalose has been suggested as a mechanism underlying insect cross-
tolerance to cold/freezing and drought. Here we show that exposing diapausing larvae of the …

Insects that naturally tolerate internal freezing produce complex mixtures of multiple
cryoprotectants (CPs). Better knowledge on composition of these mixtures, and on the …

Harmonia axyridis (Pallas) is an important natural enemy insect. Using fourth-instar larvae,
we investigated whether changing temperature (5, 15 and 25 C) can enhance the cold …

The risks of depletion of energy reserves and encountering lethally low temperatures are
considered as two important mortality factors that may limit winter survival of mosquito, Culex …
