Eighty percent of the world's nations eat insects of 1,000 to 2,000 species. [10] [11] FAO has registered some 1,900 edible insect species and estimates that there were, in 2005, some two billion insect consumers worldwide. FAO suggests eating insects as a possible solution to environmental degradation caused by livestock production. [12]
Insects as food or edible insects are insect species used for human consumption. [1] Over 2 billion people are estimated to eat insects on a daily basis. [ 2 ] Globally, more than 2,000 insect species are considered edible, though far fewer are discussed for industrialized mass production and regionally authorized for use in food.
Insects generally have a higher food conversion efficiency than more traditional meats, measured as efficiency of conversion of ingested food, or ECI. [91] While many insects can have an energy input to protein output ratio of around 4:1, raised livestock has a ratio closer to 54:1. [92]
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...

Insect protein, long hailed as a sustainable food source, hasn’t caught on in the mainstream. But in recent years, interest in insects as ingredients for animal food has been growing. A 2021 ...
This represents a trade-off between pheromone production and energy required for activities such as immune system recovery and locomotor activity. [ 13 ] When there was a third challenge, implantation, in the same males, there was a lower encapsulation rate of the nylon implants in more attractive males than the less attractive, showing how the ...
