[24] In 1961, the British biochemist Robert Kenneth Callow identified another pheromone, also known as the queen bee pheromone, with the compound ( E )-9-oxo-dec-2-enoic acid , or 9-ODA for short.

Most organisms forage, hunt, or use photosynthesis to get food, but around 50 million years ago — long before humans were around — ants began cultivating and growing their own food.
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 ...
