At colder temperatures (below 0 °C), glycogen production is inhibited, and the breakdown of glycogen into glycerol is enhanced, resulting in the glycerol levels in freeze-avoidant insects reaching levels five times higher than those in freeze tolerant insects [19] which do not need to cope with extended periods of cold temperatures.
In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the insect from adverse conditions associated with ...
Freezing of the head and thorax in other insects tends to have adverse effects on neural tissue, so it is not surprising that these protective mechanisms have been observed in certain species, but E. nugatoria is the only insect known to semi-freeze through the winter. By allowing the abdomen to freeze, evaporative water loss is reduced over ...
[6] As a result, growing degree-days are commonly used to estimate insect development, often relative to a biofix point, [6] i.e., a biological milestone, such as when the insect comes out of pupation in spring. [7] Degree-days can help with pest control. [8] Stenotus binotatus, a plant bug in the group Heteroptera
As with other livestock animals, a variety of welfare concerns can manifest during the rearing and slaughter of insects. The 5 Domains framework can be used to broadly categorize these areas of possible concern into four functional domains (nutrition, environment, behavior, and physical health) which then influence the mental domain of the animal's welfare state.

Grated Cheese. Throwing a bag of grated cheese in the freezer just feels … wrong. But multiple Redditors say that shredded cheese fares better than blocks or slices.
AFPs decrease the temperature at which an ice crystal grows, defined as the hysteretic freezing point, by an average of 2–5 °C below the melting point in insects, which can be as much as 13 °C in C. clavipes in winter when the insect is dehydrated and the AFPs concentrated. [11]
To freeze whole eggs, you need to "beat just until blended, pour into freezer containers, seal tightly, label with the number of eggs, and date, then freeze," said Elisa Maloberti, the food safety ...
